ABSTRACT

OBJECTIVE: Cyanoacrylate tissue adhesive has been presented as an alternative to sutures and several studies have compared them. The objective of this meta-analysis was to evaluate the effect of cyanoacrylate tissue adhesive on postoperative pain and swelling, following mandibular third molar surgery. MATERIALS AND METHODS: Database search was conducted in MEDLINE/PubMed and Scopus, along with extensive search in the grey literature, including randomized and non-randomized clinical trials that applied cyanoacrylate adhesive for closing mandibular third molar surgical sites and compared it with silk sutures, assessing postoperative pain and swelling. The search ended on September 22, 2023. RESULTS: Of 886 identified articles, six were included and meta-analyzed. Applying cyanoacrylate demonstrated a reduction in the overall postoperative pain (SMD = -0.57, 95% CI -1.00 to -0.15, p = 0.009). A similar outcome was noted when pain was evaluated on the first and last postoperative days, based on controlled clinical trials (SMD = -0.47, 95% CI -0.92 to -0.03, p = 0.04), and randomized trials (SMD = -0.97, 95% CI -1.31 to -0.62, p < 0.00001). Patients/sides received cyanoacrylate showed a decrease in postoperative swelling (SMD = -0.26, 95% CI -0.51 to -0.01, p = 0.04). Following the GRADE rating system, the quality of evidence on pain and swelling was judged as moderate and low, respectively. CONCLUSIONS: The use of cyanoacrylate adhesive may offer benefit in reducing postoperative pain and swelling following mandibular third molar surgery. Nevertheless, this should be further investigated, considering the low number of included reports. CLINICAL RELEVANCE: The current results could help clinicians who perform this procedure to manage postoperative pain and swelling more effectively.

ABSTRACT

OBJECTIVE: To compare the accuracy of implant position, using a combination of static and dynamic computer-assisted implant surgery (CAIS), with either static, dynamic, or freehand implant placement, in fully edentulous arches. MATERIALS AND METHODS: Twenty-one patients with a total of 88 fixtures were included. Implants were divided equally into four groups: a combination of static and dynamic CAIS (SD group), static CAIS (S group), dynamic CAIS (D group), and freehand placement (FH group). Angular deviation, as well as the 3D platform and apex deviations, were measured for all groups. Furthermore, the direction of implant deviation was recorded and compared. RESULTS: The FH group showed significantly more deviation compared to all groups, considering all the aspects, and at both the implant platform and apex. A significant difference in angular deviation between the SD and S groups (p < .001), and between the SD and D groups (p < .001) was noted, favoring the SD group. When evaluating implant distribution, the FH group showed a tendency towards the buccal, apical, and distal directions at platform and apex, while in the D group, implants shifted more to the buccal. In contrast, the SD group did not show a trend toward any specific direction. The S and SD groups did not show a statistical significance considering any direction. CONCLUSIONS: The combination of static and dynamic CAIS increases the accuracy of implant placement in fully edentulous arches when compared with either static or dynamic CAIS alone, as well as freehand placement.

ABSTRACT

This network meta-analysis was done to thoroughly evaluate the available literature on the use of different hemostatic agents for dental extraction in patients under oral antithrombotic therapy, aiming to identify the agent with the best/worst performance in bleeding control. Considering that such patients have a higher risk of bleeding, choosing the right hemostatic is essential. Twenty-three randomized clinical trials articles were included after completing the literature search. Cyanoacrylate tissue adhesive showed a reduction in the odds of postoperative bleeding events compared with conventional methods (i.e., gauze/cotton pressure, sutures), with a tendency toward a statistical significance (OR 0.03, P = 0.051). Tranexamic acid was the only agent that demonstrated a significantly lower risk of developing postoperative bleeding events (OR 0.27, P = 0.007). Interestingly, chitosan dental dressing and collagen plug had the shortest time to reach hemostasis. However, they ranked last among all hemostatic agents, regarding bleeding events, revealing higher odds than conventional measures. Therefore, it is concluded that the use of cyanoacrylate tissue adhesive and tranexamic acid gives favorable results in reducing postoperative bleeding events following dental extractions. Although chitosan dental dressing and collagen exhibited a faster time to reach hemostasis, they led to a higher occurrence of bleeding events.

ABSTRACT

OBJECTIVES: This systematic review aimed to evaluate the current evidence on the effectiveness of autogenous dentin block graft prepared chairside for alveolar ridge augmentation and compare its clinical outcomes to the main available grafting materials and techniques. MATERIALS AND METHODS: Three databases were screened, including prospective clinical studies, utilizing autogenous dentin blocks for ridge augmentation, with at least 3 months of postoperative follow-up. RESULTS: Eight articles were included, and four of them were meta-analyzed. Dentin blocks demonstrated similar vertical bone gain and significantly higher width gain, compared to bone blocks (WMD = 0.03, 95% CI -0.51 to 0.57, p = .92 and WMD = 1.34, 95% CI 0.57 to 2.12, p = .0007, respectively). Vertical and horizontal resorption were similar between the two groups (WMD = -0.36, 95% CI -0.91 to 0.18, p = .19, and WMD = -0.47, 95% CI -1.05 to 0.11, p = .11, respectively). Dentin blocks showed more incidences of postoperative complications, however, with no statistical significance (RR = 4.30, 95% CI 0.97 to 18.96, p = .054). The need for additional augmentation upon implant placement was also similar between both grafts (RR = 0.95, 95% CI 0.39 to 2.28, p = .90). Recorded incidences of graft exposure were low (2.27%), and no study stated surgical site infection. CONCLUSION: Within its limitations, this study indicates that the autogenous dentin blocks prepared chairside could be a possible alternative to the other established bone augmentation techniques for staged ridge augmentation. Nevertheless, future studies are needed to confirm its efficacy and implant success/survival in sites grafted with this material.

ABSTRACT

Dental implants have been utilized for many years to treat individuals with missing teeth. To optimize the long-term success rate of such implants, new designs, surfaces, and materials have been analyzed. It is important for the clinician to have a background in the field of implant surface design, to be familiar with the strengths and limitations of the available options, and to be aware of the alterations in surface structure that may occur following installation. This article provides a detailed review of the structure and the surface characteristics of dental implants, the modifications of implant surface, as well as the methods of evaluating implant surface structure. Moreover, it provides information concerning the structural changes that may take place at the time of dental implant placement. It is important for clinicians to be aware of such changes to plan and execute implant procedures with the highest possible success and implant survival rates.

ABSTRACT

PURPOSE: The Allogenic Demineralized Dentin Matrix (Allo-DDM) has been introduced as a new grafting material, and several investigations were conducted, showing its efficacy in bone augmentation. The objective of this systematic review was to evaluate the available literature on the Allo-DDM, revealing its clinical performance when used for implant placement procedures. METHODS: This study is registered in the PROSPERO database (number: CRD42021264885, date: 30/7/2021). Four databases, as well as the grey literature, were searched, selecting human studies where the Allo-DDM was applied to augment implant-recipient sites. RESULTS: Six articles were included. The total number of implants placed in Allo-DDM-grafted sites was 149. Mean implant stability quotient values (ISQ) were 60.4 and 68.67 for the primary and secondary ISQ, respectively (data from one study). Buccal marginal bone loss around implants was approximately 1.46 mm after 24 months of prosthetic loading (data from one study). Two studies documented a total of 6 cases of dehiscence of the grated area, however, not affecting early implant success. Histological findings from all studies showed new bone formation around the graft particles. CONCLUSION: A low number of publications are available, presenting only preliminary results, thus the long-term success/survival of implants still needs to be further explored. Moreover, the possibility of bony dehiscence with the use of this material should be investigated. Within these limitations, the Allo-DDM could be a possible alternative to other grafting materials used for bone augmentation and implant placement. Nevertheless, considering this limited evidence, future studies are necessary to confirm this conclusion.

ABSTRACT

BACKGROUND: Hemostatic agents are used to control bleeding after tooth extraction and have been compared with conventional measures (that is, sutures or gauze pressure) in several studies. The objective of this systematic review was to evaluate the benefits of topical hemostatic agents for controlling bleeding after tooth extractions, especially in patients receiving antithrombotic therapy. TYPES OF STUDIES REVIEWED: The authors conducted a literature search in MEDLINE (PubMed), Scopus, and the Cochrane Central Register of Controlled Trials, including prospective human randomized clinical trials in which researchers compared hemostatic agents with conventional methods and reported the time to achieve hemostasis and postoperative bleeding events. RESULTS: Seventeen articles were eligible for inclusion. Hemostatic agents resulted in a significantly shorter time to achieve hemostasis in both healthy patients and patients taking antithrombotic drugs (standardized mean difference, -1.02; 95% CI, -1.70 to -0.35; P = .003 and standardized mean difference, -2.30; 95% CI, -3.20 to -1.39; P < .00001, respectively). Significantly fewer bleeding events were noted when hemostatic agents were used (risk ratio, 0.62; 95% CI, 0.44 to 0.88; P = .007). All forms of hemostatic agents (that is, mouthrinse, gel, hemostatic plug, and gauze soaked with the agent) had better efficacy in reducing the number of postoperative bleeding events than conventional hemostasis measures, except for hemostatic sponges. However, this was based on a small number of studies in each subgroup. CONCLUSIONS: The use of hemostatic agents seemed to offer better bleeding control after tooth extractions in patients on antithrombotic drugs than conventional measures. PRACTICAL IMPLICATIONS: Findings of this systematic review may help clinicians attain more efficient hemostasis in patients requiring tooth extraction. This systematic review is registered in the PROSPERO database. The registration number is CRD42021256145.

ABSTRACT

Bone regeneration is currently one of the most widely researched topics in regenerative medicine. Several bone-grafting materials have been introduced and compared. However, the limitations of the currently available grafts have led researchers to investigate new materials to be used. In contrast, the periosteum performs endogenous bone regeneration as seen in physiological bone fracture repair, and transplanted periosteum has been used to induce bone regeneration in animal models. Although many of the introduced bone grafting materials have not been clinically evaluated, the use of the periosteum for bone regeneration has been documented in several clinical situations. Recently, the Micrograft concept, which was initially used to treat burn patients, where the tissue sample is cut into smaller pieces to expand the area that they can cover, has been applied to oral periosteal tissue for inclusion in scaffolds for bone defect healing, and was evaluated in various clinical bone augmentation procedures. This article first presents a brief overview of some of the commonly used bone grafts and their limitations. Next, it provides background information on the periosteum, including its histology and the cell biology and signaling involved in its osteogenic effect, periosteum-derived Micrografts, their osteogenic potential, and their recent clinical applications for bone augmentation.

ABSTRACT

This study aimed to investigate the effect of the lack of keratinized mucosa on the risk of peri-implantitis, while also accounting for possible confounding factors. A literature search was conducted in PubMed and Scopus, including human studies that assessed the presence and width of keratinized mucosa in relation to the occurrence of peri-implantitis. Twenty-two articles were included, and 16 cross-sectional studies we meta-analyzed. The prevalence of peri-implantitis was 6.68-62.3% on patient-level and 4.5-58.1% on implant-level. The overall analysis indicated that the lack of keratinized mucosa was associated with a higher prevalence of peri-implantitis (OR = 2.78, 95% CI 2.07-3.74, p < 0.00001). Similar results were shown when subgroup analyses were performed, including studies with a similar case definition of peri-implantitis (Marginal Bone Loss, MBL ≥ 2 mm) (OR = 1.96, 95% CI 1.41-2.73, p < 0.0001), fixed prostheses only (OR = 2.82, 95% CI 1.85-4.28, p < 0.00001), patients under regular implant maintenance (OR = 2.08, 95% CI 1.41-3.08, p = 0.0002), and studies adjusting for other variables (OR = 3.68, 95% CI 2.32-5.82, p = 0.007). Thus, the lack of keratinized mucosa is a risk factor that increases the prevalence of peri-implantitis and should be accounted for when placing dental implants.

ABSTRACT

Polyetheretherketone (PEEK) implants are being increasingly used to reconstruct defects in the oral and maxillofacial region. This article reports a special case of a patient with major destruction in his maxilla due to a war injury. The resultant defect was reconstructed with a 3D-printed, patient-specific, PEEK implant, restoring acceptable function and aesthetics. The patient followed up for 13 months and showed no technical or biological complications, proving the reliability of this treatment option for recreating severe maxillofacial deformities, and benefiting from the advantage they offer, which is eliminating the need for additional surgery to harvest autogenous bone grafts. Thus, when applicable, the use of PEEK implants could be a possible alternative to other treatment modalities.

ABSTRACT

OBJECTIVES: The goal of this retrospective study was to determine the significance and impact of several factors on the alveolar cleft bone grafting procedure. MATERIALS AND METHODS: The medical records were reviewed. In addition, x-rays were checked. The size of every cleft was measured in this retrospective study. The analyzed factors included sex, age, type of cleft, size of the cleft, and the type of flap used in surgery. The patients were characterized into group A (no complications, Bergland scale 1 or 2), group B (complications or Bergland scale 3), or group C (failure cases). Statistical analysis was performed with a P-value set at 0.05. RESULTS: There were 32 cases in group A, 26 in group B, and 9 in group C. Multinomial logistic regression showed an association between the type of the cleft and the size of the cleft, with the presence of complications, or achieving type 3 on the Bergland scale, with odds ratios of 5.118 and 6.000, respectively. The type of cleft was related to failure with an odds ratio of 4.833. Given a small sample, statistical analysis could not be performed to evaluate the relationship between the size of the cleft and group C. Age, sex, and the type of the flap were not significant factors. CONCLUSION: The cleft size of more than 10 mm and bilateral clefts were listed regarding their effect on the procedure. Clinicians should not overlook these factors. In addition, patients must be informed of any risks that are present.

ABSTRACT

BACKGROUND: Mandibular third molar removal is the most common surgical procedure encountered in oral and maxillofacial clinics. It also presents the greatest challenges and controversies for surgeons when surgical removal is considered. Furthermore, diverse anesthesia results and success rates are achieved after using the same concentrations of different solutions or the same amounts of local anesthetics. The purpose of this study was to examine the efficiency of using double-cartridge (3.4 ml) 4% lidocaine (high concentration) and 4% articaine with a 1:100000 epinephrine infiltration in the retromolar region for impacted lower third molar surgery. METHODS: This double-blind study included 30 patients with symmetrically impacted lower third molars. The patients were randomly selected to receive 4% articaine on one side and 4% lidocaine on the other, as a local anesthetic for third molar surgery. The onset, duration of soft-tissue numbness, pulpal sensitivity, amount of additional local anesthetic needed, pain score during the surgical procedure, and duration of the operation were recorded. RESULTS: The results of this research indicate that 86.7% of the operations in the 4% articaine group and 83.3% of those in the 4% lidocaine group were successful. Furthermore, the outcomes in both groups were not statistically significant (P > 0.05). Numbness onset occurred faster in the articaine group than it did in the lidocaine group. However, the duration of soft-tissue anesthesia and pain scores recorded immediately postoperatively were similar. CONCLUSION: It is concluded that 4% lidocaine and 4% articaine had a similar infiltration efficacy in the retromolar region and both local anesthetics are adequate for impacted lower third molar surgery. There were no statistically significant differences between the two local anesthetics regarding pain control and the duration of soft-tissue numbness during the procedure.

ABSTRACT

Impacted teeth are a frequent phenomenon encountered by every clinician. The artificial eruption of embedded teeth is the process of directing an impacted tooth into normal occlusion. This procedure is currently attracting attention, with the aim of finding the best technique to use according to each case. This article presents key information regarding impacted incisors, canines, and premolars. In addition, we describe the most common techniques to use for artificial eruption, the open and closed techniques. We review the literature concerning these techniques and outline how clinicians can manage every type of impacted tooth.
