Advancing accuracy in guided implant placement: A comprehensive meta-analysis: Meta-Analysis evaluation of the accuracy of available implant placement Methods.

OBJECTIVES: This meta-analysis aimed to determine the accuracy of currently available computer-assisted implant surgery (CAIS) modalities under in vitro conditions and investigate whether these novel techniques can achieve clinically acceptable accuracy. DATA: In vitro studies comparing the postoperative implant position with the preoperative plan were included. Risk of bias was assessed using the Quality Assessment Tool For In Vitro Studies (QUIN Tool) and a sensitivity analysis was conducted using funnel plots. SOURCES: A systematic search was performed on April 18, 2023, using the following three databases: MEDLINE (via PubMed), EMBASE, and Cochrane Central Register of Controlled Trials. No filters or restrictions were applied during the search. RESULTS: A total of 5,894 studies were included following study selection. Robotic- and static CAIS (sCAIS) had the most accurate and clinically acceptable outcomes. sCAIS was further divided according to the guidance level. Among the sCAIS groups, fully guided implant placement had the greatest accuracy. Augmented reality-based CAIS (AR-based CAIS) had clinically acceptable results for all the outcomes except for apical global deviation. Dynamic CAIS (dCAIS) demonstrated clinically safe results, except for horizontal apical deviation. Freehand implant placement was associated with the greatest number of errors. CONCLUSIONS: Fully guided sCAIS demonstrated the most predictable outcomes, whereas freehand sCAIS demonstrated the lowest accuracy. AR-based and robotic CAIS may be promising alternatives. CLINICAL SIGNIFICANCE: To our knowledge, this is the first meta-analysis to evaluate the accuracy of robotic CAIS and investigate the accuracy of various CAIS modalities.

Association between Hyperglycemia and Medication-Related Osteonecrosis of the Jaw (MRONJ).

BACKGROUND: Medication-related osteonecrosis of the jaw (MRONJ) is a type of jawbone necrosis caused by the use of drugs for some types of cancer and osteoporosis. The current study aimed to evaluate the associations between hyperglycemia and the development of medication-related osteonecrosis of the jaw. METHODS: Our research group investigated data collected between 1 January 2019 and 31 December 2020. A total of 260 patients were selected from the Inpatient Care Unit, Department of Oromaxillofacial Surgery and Stomatology, Semmelweis University. Fasting glucose data were used and included in the study. RESULTS: Approximately 40% of the necrosis group and 21% of the control group presented with hyperglycemia. There was a significant association between hyperglycemia and MRONJ (p < 0.05, p = 0.003). Vascular anomaly and immune dysfunction caused by hyperglycemia can lead to necrosis after tooth extraction. Necrosis is more common in the mandible (75.0%) and in the case of parenteral antiresorptive treatment (intravenous Zoledronate and subcutaneous Denosumab). Hyperglycemia is a more relevant risk factor than bad oral habits (26.7%). CONCLUSIONS: Ischemia is a complication of abnormal glucose levels, a possible risk factor for necrosis development. Hence, uncontrolled or poorly regulated plasma glucose levels can significantly increase the risk of jawbone necrosis after invasive dental or oral surgical interventions.

Enhancement of Hydrophilicity of Nano-Pitted TiO2 Surface Using Phosphoric Acid Etching.

Our research group developed a novel nano-pitted (NP) TiO2 surface on grade 2 titanium that showed good mechanical, osteogenic, and antibacterial properties; however, it showed weak hydrophilicity. Our objective was to develop a surface treatment method to enhance the hydrophilicity of the NP TiO2 surface without the destruction of the nano-topography. The effects of dilute and concentrated orthophosphoric (H3PO4) and nitric acids were investigated on wettability using contact angle measurement. Optical profilometry and atomic force microscopy were used for surface roughness measurement. The chemical composition of the TiO2 surface and the oxidation state of Ti was investigated using X-ray photoelectron spectroscopy. The ccH3PO4 treatment significantly increased the wettability of the NP TiO2 surfaces (30°) compared to the untreated control (88°). The quantity of the absorbed phosphorus significantly increased following ccH3PO4 treatment compared to the control and caused the oxidation state of titanium to decrease (Ti4+ → Ti3+). Owing to its simplicity and robustness the presented surface treatment method may be utilized in the industrial-scale manufacturing of titanium implants.

Point-of-care HbA1c Measurements in Oral Cancer and Control Patients in Hungary.

BACKGROUND/AIM: This study aimed to investigate the link between preoperative glycated hemoglobin (HbA1c) levels and oral cancer patients and diabetes mellitus (DM). We aimed to highlight the importance of point-of-care HbA1c measurements in oral cancer patients. PATIENTS AND METHODS: A total of 214 patients were admitted to the Department of Inpatient Care at Semmelweis University's Department of Oromaxillofacial Surgery and Stomatology between 1 September 2020 and 21 May 2021; individuals, who had undergone maxillofacial surgery under general anesthesia, were included in the study. RESULTS: There was a significant difference between the oral cancer group and the control group in terms of smoking (p=0.009) and alcohol intake (p=0.003). There was no statistically significant difference regarding sex (p=0.132) and DM (p=0.147) between the two groups. The tumor group had an 8.52% greater prevalence of DM, which was not significant. In the oral cancer group, twenty individuals (17.69%) had a higher HbA1c level than the upper level of the optimal metabolic value (6.9%). Nine participants (8.91%) in the control group had an HbA1c value greater than 6.9%, which means that their metabolic level was poor. The oral cancer group did not have higher blood glucose levels than those of the control group. CONCLUSION: No direct connection between high blood glucose levels and oral cancer was found. However, point-of-care HbA1c measurement can be a diagnostic tool to detect DM in the dental office.

Maslach and Jackson. Results: In the field of examined dimensions of burnout syndrome, the most characteristic was emotional exhaustion, which has occurred with a frequency of nearly 30% and with typically high intensity among professionals working in neonatal intensive care units (N = 278). In addition, one-fifth were characterized by a high frequency and intensity of depersonalization. At the same time, nearly a third of them experienced a decrease in personal effectiveness. Workplace and time spent in healthcare did not show a significant connection with the incidence of burnout syndrome, however, burnout syndrome occurred with a higher frequency and intensity among those working in level III. neonatal intensive care unit. Conclusion: This is the first comprehensive burnout survey among premature and new born intensive care units in

Delayed-onset infections after lower third molar surgery: a Hungarian case-control study.

OBJECTIVE: Delayed-onset infection is defined as infectious swelling and trismus accompanied by pain or the presence of suppuration starting approximately 30 days after surgery. This study aimed to describe the occurrence and potential predisposing factors of delayed-onset infection. STUDY DESIGN: A retrospective case-control study of 223 lower third molar surgeries was performed. Participants were selected from among 1102 outpatients who underwent surgery between January 2013 and June 2018 at Semmelweis University. The inclusion criterion for the case group was inflammation of the operated area after suture removal. Patients in the control group were healthy nonsmokers <26 years old who healed without complication. Statistical analysis was performed using the Shapiro-Wilk test, the Mann-Whitney U test, and Fisher's exact test. RESULTS: Complications occurred only in patients <26 years old approximately 29.5 days after surgery. A significantly higher risk was observed for younger age, total soft tissue coverage, deeper impaction, lower Nolla stage (P < .001), mesioangular direction (P = .002), and full bone coverage (P < .05). Distal space was inversely correlated with complications (P < .001). CONCLUSIONS: Lower Nolla stage, total soft tissue coverage, lack of distal space, deeper impaction, or mesioangular tilt may promote delayed-onset infection. Follow-up of at-risk patients and the maintenance of oral hygiene are recommended.

The early loading of different surface-modified implants: a randomized clinical trial.

BACKGROUND: Various surface treatment options have been adopted with the aim to improve osseointegration, reducing the overall treatment time. Implant stability of early loaded implants with different modified surfaces was compared in the present study. METHODS: Patients were selected from the Department of Oro-Maxillofacial Surgery and Stomatology at Semmelweis University. Patients randomly received SA (alumina sandblasted and acid-etched), NH (bioabsorbable apatite nanocoating) or SLA (large-grit sandblasted and acid-etched) surface implants. Outcome measures were: implant success, implant stability, and periodontal parameters. The implant stability was measured at the time of implant placement (primary stability) and six weeks after (prothesis delivery, secondary stability). Osstell and Periotest were applied to take all the measurements. The primary and secondary stability were compared in the three study groups Finally the periimplant probing depth appearing after three months of loading was checked on 6 points around to the implant-supported prostheses. Shapiro-Wilk and Mann-Whitney tests were used for the comparison between the study groups. RESULTS: A total of 75 implants with different length and diameter were inserted into various positions. One implant failed spontaneously at the fourth week after implant placement. The survival rate was 98,7%. Comparing the primary and secondary stability values, the data were significantly improved in every groups. The difference was the highest in the NH group, however, this difference was not significant compared to the two other groups. Good periodontal parameters were experienced in all the tested implants, independently by the groups. CONCLUSIONS: With the limitation of the present study, all the implants showed improved stability six weeks after implant placement. A trend of higher result was found for the NH group. Further studies with longer follow-up are needed to confirm this preliminary results. TRIAL REGISTRATION: Current Controlled Trials ISRCTN13181677; the date of registration: 04/03/2021. Retrospectively registered.

Risk assessment of bisphosphonate-related osteonecrosis of the jaw based on CBCT scans / A biszfoszfonátkezelés állcsontnekrózist eloidézo kockázatának megítélése CBCT-felvételek alapján.

INTRODUCTION: Bisphosphonate-related osteonecrosis of the jaw is a condition that severely affects the quality of life, therefore an early diagnosis is of utmost importance (both from a general and a surgical point of view), alongside with an accurate assessment of the risk of emergence of the disease. AIM: Estimation of the prognosis is not resolved; among several radiological options those used in dentistry seem the most fit for the purpose, with cone-beam computed tomography (CBCT) being superior in this task. Assessment of the risk of BRONJ developed following orally applied bisphosphonate is unemphatic in most case studies - these focus more on the intravenous application carrying a greater risk of BRONJ. METHOD: In contrast with the studies published so far, we performed our measurements on preoperative CBCT scans, thereby directly studying the possibility of risk assessment. Our measurements were conducted through evaluating CBCT scans. We chose the frontal section in the midline of the mental foramen as the representative area. We measured density and thickness of the cortical bone on several given points; the diameter of the mental foramen was also measured. In the first group, we examined patients suffering from osteoporosis who had developed BRONJ following oral bisphosphonate treatment. In the second group, we looked at patients suffering from osteoporosis, who had received oral bisphosphonate therapy for this condition but did not develop BRONJ after oral surgery. As control group, we chose patients suffering from osteoporosis who had not received any of the medications known to cause BRONJ. RESULTS: Based on our results, it is clear that there is no significant difference in the bone density of those patients who developed BRONJ and those who did not, examining the preoperative CBCT scans. CONCLUSIONS: Using CBCT scans (and thereby submitting the patient to radiation exposure) in order to estimate the possibility of BRONJ following oral bisphosphonate treatment for osteoporosis is not recommended. It is important not to expose patients to more radiation than strictly necessary to predict BRONJ following oral bisphosphonate treatment in accordance with the ALARA (as low as reasonably achievable) principle.

Heat Generation During Guided and Freehand Implant Site Preparation at Drilling Speeds of 1500 and 2000 RPM at Different Irrigation Temperatures: An In Vitro Study.

PURPOSE: The purpose of our study was to evaluate the impact of different irrigation fluid temperatures on intraosseous temperature increment during guided and freehand implant site preparation. MATERIALS AND METHODS: Bovine rib segments were used. Temperature was detected using K-type thermocouples. The studied groups were defined as combinations of the following: drilling speed (1500, 2000 RPM), drill diameter (2.0, 2.5, 3.0, 3.5 mm), surgical method (guided, freehand), and irrigation fluid temperature (10°C, 15°C, 20°C). The data were analysed with Kruskal-Wallis analysis of variance (ANOVA) and ANOVA, as appropriate. RESULTS: At 1500 RPM, guided drilling with 20°C irrigation fluid yielded temperature values exceeding the necrotic threshold (47°C) when performed with bits of 3.0 and 3.5 mm diameters. Meanwhile, 15°C irrigation managed to keep the mean increment below 8.0°C at the diameter of 3.5 mm for both guided and freehand surgery. However, 10°C irrigation cancelled every statistically significant difference between guided and freehand groups. At 2000 RPM and with 20°C irrigation, mean peak temperatures exceeded the necrotic threshold at the diameters 3.0 and 3.5 mm (guided) and 3.5 mm (freehand). When applying 10°C irrigation, though, all measurements indicated peak temperatures in the safe zone. CONCLUSION: Drillings at 1500 and 2000 RPM, in a guided setting, cause temperature elevations that exceed the necrotic threshold. A speed of 2000 RPM drilling may produce potentially harmful temperatures also in a freehand setting. 10°C and 15°C irrigation kept temperature increments in the safe zone at 2000 RPM and 1500 RPM, respectively.

[Incidence and case-control study of delayed-onset infection after lower third molar surgery]. / Az alsó bölcsességfogak mutéti eltávolítását követo késoi posztoperatív gyulladás (delayed-onset infection) vizsgálata.

INTRODUCTION AND AIM: Delayed-onset infection was defined as an infectious swelling and trismus accompained by pain or the presence of suppuration starting after the discharge of the patient, generally a week after surgery. Our aim was to describe incidence and possible risk factors of delayed-onset infection after lower wisdoom tooth removal. MATERIAL AND METHODS: Retrospective study of 851 lower third molar surgeries, performed between January 2013 and August 2017 at Semmelweis University Faculty of Dentistry, Department of Oro-Maxillofacial Surgery and Stomatology, has been done. The teeth were removed by 2 surgeons. Under age of 26, a case-control study comprising a total of 150 lower third molar surgeries were done to indentify possible risk factors. RESULTS: 10 delayed-onset wound infections were recorded after suture removal (1.17% of the patients). The mean time elapsing from surgery to delayed-onset infection was 30 days. Lower third molars with total soft tissue coverage, a bigger amount of bone coverage, a lack of distal space (Pell-Gregory class III), deeper impaction (Pell-Gregory classes B, C) or mesioangular tilt are associated with the development of this complication (p<0.05). Female sex and young age seem to be risk factors, too. CONCLUSION: Patients with risk factors should be warned that infection may still occur several weeks after surgery. The clinicians should observe these patients longer and emphasize keeping their wound clean for a prolonged period. Orv Hetil. 2018; 159(31): 1278-1283.

Intraosseous Heat Generation During Osteotomy Performed Freehand and Through Template With an Integrated Metal Guide Sleeve: An In Vitro Study.

OBJECTIVE: To investigate drill wear and consequent intraosseous temperature elevation during freehand and guided bone drilling, with attention to the effect of metal-on-metal contact during guided drilling. MATERIALS AND METHODS: Osteotomies were performed on bovine ribs, with 2.0 mm diameter stainless steel drill bits of the SMART Guide System, under 3 sterilization protocols, at 800, 1200, 1500, and 2000 rpm. Sterilization was performed after every 3 drilling. Temperature was measured after every 30 drilling. RESULTS: The studied contributing factors had a cumulative effect, and each contributed significantly to temperature elevation. Whether guide use led to a near-necrotic (47°C) temperature increment depended largely on the applied sterilization protocol. CONCLUSION: The metal sleeve is a significant contributing factor to heat generation during guided osteotomy, but its effect can be offset by keeping the other studied factors under control.

Effect of the Combination of Low-Speed Drilling and Cooled Irrigation Fluid on Intraosseous Heat Generation During Guided Surgical Implant Site Preparation: An In Vitro Study.

PURPOSE: Investigating the effect of the combination of low-speed drilling and cooled irrigation fluid on intraosseous temperature rise during guided and freehand implant surgery. MATERIALS AND METHODS: Bovine ribs were used as bone specimens. Grouping determinants were as follows: drill diameter (2.0, 2.5, 3.0, and 3.5 mm), irrigation fluid temperature (10°C, 15°C, and 20°C), and surgical method (guided and freehand). Drilling speed was 800 rpm. Results were compared with previous ones using 1200 rpm. Temperature measurements were conducted using K-type thermocouples. RESULTS: No mean temperature change exceeded 1.0°C if irrigation fluid cooled to 10°C was used, regardless of the drill diameter or the surgical method, with the highest elevation being 2.10°C. No significant reduction was measured when comparing groups using 15°C and 20°C irrigation fluids, regardless of both drill diameter and surgical method. CONCLUSION: The use of irrigation fluid being cooled to 10°C combined with low-speed drilling (800 rpm) seems to be a safe method for implant site preparation and drilling through a drilling guide in terms of temperature control.

Effect of pre-drilling on intraosseous temperature during self-drilling mini-implant placement in a porcine mandible model.

This in vitro study investigated intraos seous heat production during insertion, with and without pre-drilling, of a self-drilling orthodontic mini-implant. To measure temperature changes and drilling times in pig ribs, a special testing apparatus was used to examine new and worn pre-drills at different speeds. Temperatures were measured during mini-implant placement with and without pre-drilling. The average intraosseous temperature increase during manual mini-implant insertion was similar with and without pre-drilling (11.8 ± 2.1°C vs. 11.3 ± 2.4°C, respectively; P = 0.707). During pre-drilling the mean temperature increase for new drills was 2.1°C at 100 rpm, 2.3°C at 200 rpm, and 7.6°C at 1,200 rpm. Temperature increases were significantly higher for worn drills at the same speeds (2.98°C, 3.0°C, and 12.3°C, respectively), while bone temperatures at 100 and 200 rpm were similar for new and worn drills (P = 0.345 and 0.736, respectively). Baseline bone temperature was approximated within 30 s after drilling in most specimens. Drilling time at 100 rpm was 2.1 ± 0.9 s, but was significantly shorter at 200 rpm (1.1 ± 0.2 s) and 1,200 rpm (0.1 ± 0.03 s). Pre-drilling did not decrease intraosseous temperatures. In patients for whom pre-drilling is indicated, speeds of 100 or 200 rpm are recommended, at least 30 s after pilot drilling.

[Prospective randomized study regarding the effect of the preoperative antibiotic and chlorhexidine rinse on wound healing after mandibular third molar surgery]. / A preoperatív antibiotikus és antiszeptikus kezelés hatása a mutéti úton eltávolított alsó bölcsességfogak sebgyógyulására ­ prospektív randomizált vizsgálat.

INTRODUCTION AND AIM: The study compares the antibiotic prophylaxis combined with postoperative antibiotic therapy to preoperative chlorhexidine rinse combined with postoperative antibiotic therapy in preventing complications after surgical removal of a mandibular third molar. METHOD: 71 healthy patients in four groups were enrolled in the study: I. prophylactic dose of 2000 mg of amoxicillin clavulanate, continued with amoxicillin clavulanate postoperatively; II. prophylactic dose of 600 mg of clindamycin, continued with clindamycin postoperatively; III. prophylactic chlorhexidin rinsing, continued randomized amoxicillin clavulanate or clindamycin postoperatively; IV. control, with clindamycin postoperatively. RESULTS: The pain was smaller in the prophylaxis groups. Alveolitis occurred only in the control group: 2 patients. Wound opening occurred in 22,2 % in group IV., 14,2 % in group II, 10 % in group I., 5 % in group III. CONCLUSION: We consider completing the indicated postoperative antibiotic prescription with antibiotic or antiseptic prophylaxis. Chlorhexidin prophylaxis could have the same positive effect. Orv. Hetil., 2017, 158(1), 13-19.

Impact of rheumatoid arthritis in oral surgery and implantology treatment based on literature.

Rheumatoid arthritis (RA) is an autoimmune disease that results in a chronic, systemic inflammatory disorder that principally attacks synovial joints. The pathology of the disease process often leads to the destruction of articular cartilage and the bone. Normal bone remodeling cycle requires the balance between bone resorption and bone deposition which is determined by the activities of two principle cell types, namely, osteoclasts and osteoblasts. Osteoblasts and osteoclasts, coupled together via cytokine mediated cell signaling. The dominance of pro-inflammatory cytokines in bone homeostasis leads to osteolysis. Many articles have been published about the pathobiochemical similarity between rheumatoid arthritis and periodontitis, whereas the role of the disease in bone regeneration and osseointegration is less proven. According to the international literature in rheumatoid arthritis, due to frequent periodontitis, decreased salivary secretion, medication, as well as a decrease in bone regenerative potential, rheumatoid arthritis is considered as relative contraindication in implantology. In daily practice, we face more frequently with rheumatoid arthritis which makes the topic so important in oral surgery and implantology. It can be said that adequate preoperative preparation (healthy periodontal status, antibiotic protection, consultation with the rheumatologist to modify medication) interventions can be done more safely. The risk of failure is higher in patients suffering from rheumatoid arthritis of the underlying disease which fact is important to be communicated before surgical intervention.

[Dental and oral surgical treatment of medication-induced bleeding patients: Audit of the national guideline in Hungary]. / A gyógyszer indukálta vérzékeny betegek fogorvosi, szájsebészeti ellátása: a 2015-ös hazai szakmai ajánlás alkalmazása és értékelése.

INTRODUCTION: In 2015 a new Hungarian guideline was published regarding dental treatment and management of anticoagulated patients in agreement of the Hungarian Association of Oral and Maxillofacial Surgeons and the Dental Implantology Association of Hungarian Dentists. AIM: The aim of the authors was to evaluate the efficiency and safety of local hemostatic measures recommended by the guideline in anticoagulated patients. METHOD: In these patients, postoperative bleeding episodes were examined after dental and oral surgical treatments, retrospectively. RESULTS: Overall 263 bleeding risk cases were treated; 138 patients with vitamin K antagonists, 97 patients with antiplatelet therapy and 6 patients with novel oral anticoagulants. Six patients (2.3%) had minor postoperative bleeding after the "one hour control", while one patient needed a night duty support (0.5%). In contrast, 86 patients who were treated in rural practices neglecting the guideline attended the night duty with postoperative bleeding (3 patients treated with vitamin K antagonists, 24 patients taking low molecular weight heparin, 30 patients receiving antiplatelet therapy and one patient on novel oral anticoagulant therapy. CONCLUSIONS: The Hungarian guideline can be applied safely, without increasing the risk of postoperative bleeding, however, rural dental practices are frequently unprepared for these treatments.

Intraosseous generation of heat during guided surgical drilling: an ex vivo study of the effect of the temperature of the irrigating fluid.

We measured the rise in the intraosseous temperature caused by freehand drilling or drilling through a surgical guide, by comparing different temperatures of irrigation fluid (10°C, 15°C, and 20°C), for every step of the drilling sequence (diameters 2.0, 2.5, 3.0, and 3.5mm) and using a constant drilling speed of 1200rpm. The axial load was controlled at 2.0kg. Bovine ribs were used as test models. In the guided group we used 3-dimensional printed surgical guides and temperature was measured with a thermocouple. The significance of differences was assessed with the Kruskal-Wallis analysis of variance. Guided drilling with 10°C irrigation yielded a significantly lower increment in temperature than the 20°C-guided group. When compared with the 20°C freehand group, the reduction in temperature in the 10°C guided group was significantly more pronounced at all diameters except 3.5mm. Finally, when the 10°C-guided group was compared with the 15°C groups, the temperature rise was significantly less at 2.5 and 3.0mm than with the guided technique, and at 3.0mm compared with the freehand technique. We suggest that the use of 10°C pre-cooled irrigation fluid is superior to warmer fluid for keeping temperature down, and this reduces the difference between guided and freehand drilling.

[Difficulties in differential diagnosis of dentin dysplasia. Case report]. / A dentin dysplasia differenciáldiagnosztikai nehézségei. Esetismertetés.

In cases of periapical lesions of unknown origin we have to keep in mind the possibility of dentin dysplasia. From the differential diagnostic point of view of differential diagnosis it is important to recognize this disease as it significantly influences the treatment modality. It is an anomaly of unknown etiology that could affect both deciduous and permanent dentition. Dentin dysplasia presentation varies clinically and radiologically. A rare manifestation which affects 1: 100000 patients is spontaneously occurring either as periapical abscess or odontogenic cyst. The affected teeth could become mobile and eventually lost. Dentin dysplasia is a genetic disease which shows autosomal dominant inheritance and characterized by abnormal formation of dentin structure which occurs during tooth development. For this article we have reviewed available literature and PubMed database. Dentin dysplasia increases the risk of early tooth loss and associated with it esthetic and functional disturbances. As a result it can influence the psychological and social status of the patients and affect their quality of life.

[Dental management of hemorrhage-prone patients]. / A vérzékeny betegek fogorvosi ellátása.

The authors present a proposal of dental treatment and management of anticoagulated patients and of patients on antiplatelet therapy, with the approval by the Hungarian Association of Oral and Maxillofacial Surgeons and by the Dental Implantology Association of Hungarian Dentists. This current guide was based on recent Hungarian and on several foreign national guidelines and considers significant publications from international literature.

[Survival and success rate of dental implants treated with high intensity laser]. / Lézerrel felületkezelt dentális implantátumok túlélési és sikerességi rátájának vizsgálata.

Clinical and radiological evaluations were conducted in patients with high energy Nd : glass laser-treated dental implants. These patients underwent dental implantation surgery between 1997 and 2006. Strict success criteria were used for the examination and analysis of implants. Based on clinical and radiological evaluation, success and survival rates of laser surface treated dental implants were similar to those of sandblasted, acid-etched surface implants frequently reported in the literature. Specific surface morphology and high degree of purity of laser surface treated dental implants ensure excellent osseointegration and a good clinical performance also on the long-term.
