RESUMO

Background and objectives: Although it is very uncommon, medication-induced osteonecrosis of the jaw (also known as MRONJ) can have serious consequences. Traditionally, this adverse event has been recognised in patients who were treated with bisphosphonate (BP) drugs. Nevertheless, in recent years, it has been established that individuals having treatment with various types of medications, such as a receptor activator of nuclear factor kappa-Β ligand inhibitor (denosumab) and antiangiogenic agents, have had the same issue. The purpose of this research is to determine if the application of human amniotic membrane (hAM) may be used as a therapy for MRONJ. Material and Methods: A multi-source database (MEDLINE, EMBASE, AMED, and CENTRAL) systematic search was performed. The major objective of this study is to obtain an understanding of the efficacy of hAM when it is employed as a treatment modality for MRONJ. The protocol of this review was registered in the INPLASY register under the number NPLASY202330010. Results: The authors were able to include a total of five studies for the quality analysis, whereas for the quantity evaluation, only four studies were eligible. A total of 91 patients were considered for the investigation. After treatment with human amniotic membrane (hAM), a recurrence of osteonecrosis was observed in n = 6 cases (8.8%). The combined efficacy of surgical therapy and the use of hAM resulted in an overall success rate of 91.2%. Intraoperative complications were only documented in one article, and they were mostly caused by the positioning of the hAM, which led to wound breakdown at the surgical site. Conclusions: Based on the small amount of data and low-quality research included in this study, using human amniotic membranes to treat MRONJ might represent a feasible option. Nevertheless, further studies with a wider patient population are required to understand the long-term impacts.

RESUMO

BACKGROUND: The treatment of patients by the use of immediate implant placement in post-extractive site is a challenging procedure. PURPOSE: A 3-year clinical and radiological study of post-extractive implants placed using flapless guided surgery and immediately functioning. MATERIALS AND METHODS: Thirty-two patients (23 females and 9 males), aged between 44 and 73 years (a mean age of 59.5) were treated with immediate full arch restorations and flapless implant surgery in fresh extraction and healed sites. A double-guide technique stent in conjunction with the NobelGuide system (Nobel Biocare AB, Göteborg, Sweden) was used. RESULTS: A total of 285 implants over 32 patients were assessed. The patients were clinically and radiologically followed for 3 years. One hundred and ninety-five implants were placed in the maxilla and 90 in the mandible. Eight patients received implants in both arches. One hundred and ninety-seven implants were placed in extraction sites (137 maxilla, 60 mandible) and 88 in healed sites (58 maxilla and 30 mandible). The overall cumulative implant survival rate (CISR) was 97.54%. Two implants failed in maxillary healed sites (CISR 96.55%), three in maxillary extraction sites (CISR 97.81%), and two in mandibular extraction sites (CISR 96.66%). No implant failed in healed mandibular sites (CSR 100%). All fixed prostheses maintained stability and good functionality during the follow-up, accounting for a cumulative prosthesis survival rate (CPSR) of 100%. The overall marginal bone level (MBL) was -0.52 mm (SD -0.18) after 6 months, -0.88 mm (SD -0.20) after 12 months, -1.05 mm (SD -0.21) after 24 months, and -1.32 mm (SD -0.41) after 36 months. CONCLUSIONS: Computer-guided surgery using double-template technique (DTT) shows a predictable outcome in the medium term, decreasing treatment timing and patient discomfort.

RESUMO

OBJECTIVE: The purpose of this report is to compare satisfaction of patients rehabilitated with full-mouth fixed prostheses using computer-aided flapless implant placement and immediate loading with patients rehabilitated with conventional removable prostheses. MATERIALS AND METHODS: The study included 30 consecutive fully edentulous patients who received 312 implants and 30 matched controls treated with conventional removable prostheses. Mandible and maxilla were treated in the same surgical session with computer-guided flapless approach using NobelGuide protocol. Prefabricated screw-retained fixed prostheses were inserted at the end of surgery. Clinical and radiographic evaluations were assessed at 6, 12, and 36 months. At baseline and 5 years after prostheses delivery, patients answered OHIP-EDENT questionnaire (Oral Health Impact Profile for Edentulous subjects) to assess satisfaction. RESULTS: The implant survival rate was 97.9%, whereas the average marginal bone loss was 1.9 ± 1.3 mm after 3 years. At 6 months, patients showed significantly greater satisfaction with their fixed rehabilitation as compared to conventional dentures. CONCLUSIONS: The results of this study confirm that rehabilitation with a prefabricated fixed prosthesis supported by implants placed with NobelGuide protocol significantly increases the quality of life in fully edentulous patients when compared with complete dentures.

RESUMO

The reconstruction of edentulous patients with adequate bone volume and density by the use of bone graft and, subsequently, the placement of dental implants has become a viable treatment option with high predictability. According to many authors, maxillary antral cysts are one of the most common benign pathologies of the maxillary sinus, and they also represent an important contraindication to sinus regenerative surgical technique. The authors report a case of maxillary atrophy which is augmented by fresh frozen bone chips in the presence of antral cysts.

RESUMO

STATEMENT OF PROBLEM: Immediate occlusal loading of dental implants in the edentulous mandible has proven to be an effective, reliable, and predictable treatment protocol. However, there is limited long-term data available in the literature, when an electroeroded definitive cast-titanium fixed prosthesis is used for this treatment protocol. PURPOSE: The aim of this study was to evaluate the clinical effectiveness of dental implants (Astra Tech Dental, Mölndal, Sweden) in the edentulous mandible immediately loaded with an electroeroded cast-titanium screw-retained fixed prosthesis. MATERIALS AND METHODS: Forty-five patients received five implants each in the interforaminal area. All the implants were inserted with torque up to 40 Ncm and the distal implants were distally tilted approximately 20 to 30 degrees to minimize the length of posterior cantilevers. Implants were loaded within 48 hours of placement with an acrylic resin-titanium screw-retained prosthesis fabricated by electroerosion. RESULTS: Two of the 225 inserted implants failed after 3 and 16 months of healing, respectively, with a cumulative survival rate of 99.1% and a prosthetic survival rate of 97.8%. CONCLUSION: Immediate loading of tilted dental implants inserted in the edentulous mandible with a screw-retained titanium definitive prosthesis fabricated with electrical discharge machining provide reliable and predictable results.

RESUMO

BACKGROUND: This investigation is a clinical and histological assessment of fresh-frozen bone use in the reconstruction of maxillary alveolar ridges. The study evaluates the effectiveness of this material as a bone filler prior the placement of dental implants. PATIENTS AND METHODS: Sixteen patients with atrophic maxillary ridges underwent maxillary reconstruction with fresh-frozen tibial human block grafts prior to implant placement. Sampling procedures were carried out 4, 6 and 9 months later when a bone core was removed from the grafts for histological and histomorphometric analysis. RESULTS: Eighteen blocks were placed, and each patient received either 1 or 2 blocks. During the sampling procedures, all of the grafts were found to be firm in consistency, well-incorporated, and vascularized. A total of 34 implants were placed into the grafts with a minimum of 40-Newton-cm torque in all cases. The follow-up period ranged from 18 to 30 months. No implants were lost. The histological analysis revealed vital bone with mature and compact osseous tissue surrounded by marrow spaces. CONCLUSION: Bone allografts can be used successfully as graft material for the treatment of maxillary ridge defects. This type of bone graft can be used safely in the areas of implant placement as a suitable alternative to autogenous grafts.

RESUMO

BACKGROUND: There is a lack of consensus on the appropriate management of solitary plasmacytoma (SP) of the jaw. The aim of the present investigation was to provide scientific evidence for the optimal management of this disease through a systematic literature review. METHODS: The included articles are published in English from 1948 to March 2011 and describe the population affected by SP of the jaw with site, clinical and radiographic features, special findings, initial diagnosis, treatment, and follow-up. RESULTS: Fifty cases of SP of the jaw were identified. It typically presents as a single osteolytic lesion with no plasmocytosis involvement of bone marrow. Long bones and vertebrae are the most common sites of SP. Rarely, it involves the jaw occurring in only 4% of cases, mainly in the bone marrow-rich areas, angulus and ramus. Solitary plasmacytoma of the jaw has a worse prognosis than multiple myeloma (MM), and in half of the cases, it evolves in MM. CONCLUSIONS: Because SP of bones is an uncommon tumor that rarely involves the jaws, through this article we emphasize early diagnosis and appropriate management to avoid progression to MM.

RESUMO

Squamous odontogenic tumor (SOT) is a benign, locally infiltrative intraosseous tumor composed of well-differentiated squamous epithelium in a fibrous stroma. It seems to derive from the epithelial rests of Malassez in the periodontal ligament space. It presents an odontogenic origin, involving both the upper and lower maxillary bone, mainly areas without teeth or connective tissue of the odontogenic cysts. Clinically, SOT could be asymptomatic (3 cases), notwithstanding it is mainly characterized by pain, swelling, and tooth/teeth mobility. The most typical presentation of SOT is a slowly growing endobony lesion arising within a single periodontal location. Frequent misdiagnosis concerns either ameloblastoma and squamous cell carcinoma and fibroma. Since its first description in 1975, less than 50 cases have been identified. In light of the few reported cases, there are no consistently recorded clinical and radiographic features of SOT, and there is no predictable sex or site predilection. Diagnosis is predicated on recognition of the histopathologic features of SOT to obviate possible misdiagnosis of malignancy or ameloblastoma.We report the first case of SOT that arose in the vicinity of an implant. Through a meticulous review of literature, we discuss current etiology, pathogenesis, and treatment.

RESUMO

BACKGROUND: Insufficient bone volume in the posterior maxilla can be a major problem when placing dental implants. One of the goals of sinus augmentation procedures is the creation of sufficient volume of vital bone for the subsequent insertion and complete osseointegration of implants placed in the posterior maxilla. The aim of the present study was a clinical, histological and histomorphometrical analysis of maxillary sinus augmentation using human fresh frozen bone (FFB) allografts for maxillary sinus lift augmentation procedures. METHODS: Fifteen patients were treated with maxillary sinus augmentation using FFB. After three months, a bone biopsy was taken before implant placement in order to evaluate the healed bone from a histological and histomorphometrical point of view. After further three months, all implants were osseointegrated according to radiographic and clinical examinations. Abutment connection was performed and the patients received prosthetic restoration of the missing teeth. RESULTS: Histologically all the specimens showed signs of active remodelling and all the tissues were free of inflammatory cells. After 12 months of assessment, no implants had failed. CONCLUSION: Our findings suggest that FFB is a biocompatible material that can be successfully used for maxillary sinus augmentation.

RESUMO

BACKGROUND: Immediate implant placement after tooth extraction is a predictable solution in various clinical situations. The purpose of this study was to evaluate the predictability of a treatment, including the placement of implants, using a modified insertion technique at the time of maxillary molar extraction. MATERIALS: Sixty-eight patients with a total of 68 teeth scheduled for tooth extraction and immediate implant placement into fresh sockets were included in the study. Implants were positioned just after teeth removal and, in case of necessity, a regenerative therapy was performed at the same time. After a 3-month period of healing, implants were restored with single crown fixed prostheses. RESULTS: All implants restored with single crowns were monitored for 36 months; only, 3 implants failed with a cumulative survival rate of 97.96%. CONCLUSION: The combination of atraumatic extraction of maxillary molars, sufficient residual inter-radicular bone, and the use of appropriate regenerative material at the time of implant insertion, represents a predictable long-term treatment.

RESUMO

BACKGROUND: Localized bone defects in the maxilla are commonly reconstructed with autologous mono-cortical bone blocks prior to the placement of dental implants. This study presents a clinical, histological and histomorphometric analysis on the use of mandibular ramus block grafts for ridge augmentation. MATERIALS AND METHODS: mono-cortical bone blocks from the mandibular ramus were grafted in 15 patients. The bone grafts were left to heal for period varying from 3 to 9 months. Afterwards, 30 implants were inserted and bone samples were removed for subsequent histological analysis. RESULTS: All the bone grafts were successful and resorption was minimal. There were no implant failures. At graft placement, mean lateral augmentation was 4.6+/-0.73mm, which, later, at the time of implant insertion, reduced to 4+/-0.77mm. Histological evaluation indicated signs of active remodelling in all specimens. However, the grafted bone contained substantial amounts of non-vital bone (NVB) and generally weak neo-vascularization regardless of the time of biopsies. CONCLUSIONS: The outcome of the study suggests that the larger part of osteocytes in mono-cortical bone do not survive grafting and neo-vascularization of non-vital grafted bone is difficult because of the slow remodelling process into new vital.

RESUMO

Effectively restoring a grossly atrophic maxilla can be difficult for the implant surgeon. The placement of dental implants in patients who are edentulous in the posterior maxilla can present difficulties because of deficient posterior alveolar ridge and increased pneumatization of the maxillary sinus, resulting in a minimal hard tissue bed. Implant placement requires adequate quality and quantity of bone, especially in the posterior maxilla. Insufficient bone height and width in this area of the maxilla, because of expansion of the maxillary sinus and atrophic reduction of the alveolar ridge, represents a contraindication for conventional insertion of dental implants. The reconstruction of edentulous patients with adequate bone volume and density by the use of bone graft and, subsequently, the placement of dental implants has become a viable treatment option with high predictability. It is commonly shared that autologous bone graft is the gold standard grafting method in the augmentation of Higmoro antrum and in any kinds of guided bone regeneration. In this article, the authors report a case of severe maxillary atrophy that is augmented by block bone graft harvested from iliac crest. An early placement of implants is possible due to the quick healing of the site, as proven by histologic examinations.

RESUMO

The placement of implants requires adequate basic conditions. Insufficient bone height and width in the area of the maxilla, because of expansion of the maxillary sinus and atrophic resorption of the alveolar ridge, represent a common anatomical complication, which can be solved by augmentation of the floor of the maxillary sinus. It is commonly shared that autologous bone graft is the gold standard method in the augmentation of the Higmoro antrum. The reconstruction of atrophies with adequate bone volume and density has become a viable treatment option with high predictability and success rates. The purpose of this study was to present the results obtained with a surgical procedure aimed at reconstructing (rehabilitating) advanced maxillary atrophies. This method includes the use of intramembranous, corticocancellous bone grafts harvested from the iliac crest. These are then fixed to the residual bone by endosseous implants.

RESUMO

AIMS: The number of patients who need treatment for dentofacial abnormalities has increased over the past 30 years. Facial alterations can influence both the patient's self-confidence and his interpersonal relationships, possibly generating emotional or physical handicaps. This qualitative study discusses a patient's psychological dissatisfaction with a postoperative outcome, despite the esthetic and functional success of the treatment. METHODS: The Oral Health Status Questionnaire, Post Surgical Satisfaction Questionnaire, Illness Behavior Questionnaire, and a clinical interview were used for the research methodology. RESULTS: Oral surgeons are encouraged to identify, presurgery, the patient's true motivation. An efficacious behavioral model is proposed that might help the patient transition through the consequences stages of the psychosocial changes associated with facial reconstructive surgery. CONCLUSION: Orthognathic surgery involves more than the correction of a physical problem. The psychological needs of the patient must be recognized and acknowledged, and communication between surgeons and patients is essential. It is important to understand that any surgical treatment that modifies body image could generate psychological disorders for some patients. Early surgical intervention and a referral for psychological counseling may reduce long-term morbidity. This case report should alert attending surgeons and orthodontists to possible unfavorable psychological sequelae.

RESUMO

AIM: To evaluate a sample of patients treated with orthognathic surgery, establishing the emotional and self-perception differences between the pre- and postsurgical assessment. MATERIAL AND METHODS: Several questionnaires (Body Dysmorphic Disorder Examination, State Trait Anxiety Inventory, Self-Rating Depression Scale, Oral Health Status Questionnaire, Post-Surgical Satisfaction Questionnaire) were administered to the sample of 30 patients; these were used to study the data related to body image, level of anxiety, eventual depressive status, quality of life, and postsurgical satisfaction. RESULTS: The longitudinal study results outline the impact of orthognathic surgery on the psychological and emotional well-being of the patient and the need for the specialist to understand the emotional status and expectations of the patient.
