Maxillary sinus functions and complications with lateral window and osteotome sinus floor elevation procedures followed by dental implants placement: a retrospective study in 60 patients.

AIM: The aim of the study was to evaluate retrospectively maxillary sinus functions and complications by using generally accepted diagnostic criteria with lateral window and osteotome sinus floor elevation (OSFE) procedures followed by dental implants placement. MATERIALS AND METHODS: A group of 60 patients in whom a SFE with the two procedures (lateral window and OSFE) followed by dental implants placement had been performed were evaluated retrospectively for sinus functions and complications from the time of procedure up to 24 months using a questionnaire, conventional clinical and radiographic examination. RESULTS: Number of patients suffered dizziness accompanied by nausea immediately after OSFE was more than the lateral window procedure and the symptoms disappeared within 2 to 4 weeks. Maxillary sinus membrane perforations occurred and small for 4 out of 79 procedures, two cases for OSFE and two for lateral window procedure had been repaired. No more complications had been detected for all the patients up to 24 months. CONCLUSION: Based on the results of this study, SFE with lateral window and osteotome procedures followed by dental implants placement did not interfere with maxillary sinus function and no obvious complications had been detected up to 24 months. CLINICAL SIGNIFICANCE: The clinician performs SFE with either lateral window or osteotome procedures needs to understand the difficulties and morbidity arising in the event of complications and must be able to correctly judge the individual risk and the presence of modifying factors that may cause these complications.

Incidence of Neurosensory Disturbance and Success Rates of Solid-Screw Implants Placed in Conjunction with Inferior Alveolar Nerve Transposition.

BACKGROUND: Implant-supported prosthetic rehabilitation of a severely atrophic posterior mandibular alveolar ridge is a real challenge. Implant placement in such situations is very difficult and implies the risk of inferior alveolar nerve (IAN) damage. PURPOSE: The purpose of this study is to evaluate the incidence of neurosensory disturbance and the cumulative survival of dental implants placed after the IAN transposition (IANT) procedures followed by dental implants placement. MATERIALS AND METHODS: Twenty International Team for Implantology implants were placed in eight patients following unilateral IANT. In two patients, nerve transposition was performed bilaterally, and hence, a total of 10 IAN transposition surgeries were performed. Neurosensory dysfunction was objectively evaluated by using light touch test (LT), pain test (PT), and 2-point discrimination test (2-DT). In addition, patients were asked to answer a short questionnaire to investigate the individual feeling of discomfort and advantages related to this surgical technique. The mean follow-up periods were 47.1 months (range 12-78 months). RESULTS: Neurosensory disturbance (i.e., disturbance registered by the LT, PT, and 2-DT tests) was experienced in 2 of 10 cases. The cumulative implant survival was 100%. However, at the time of data analysis (12-79 months after surgery), all patients indicated that they would go through the surgery again. CONCLUSION: IANT can permit the placement of implants with adequate length and good initial stabilization as used in routine sites, with the same favorable prognosis. All patients felt that they had received benefits from their new prostheses in terms of improved comfort, chewing efficiency, and esthetics.

Management of Broken Dental Implant Abutment in a Patient with Bruxism: A Rare Case Report and Review of Literature.

This rare case report describes prosthodontic complications resulting from a dental implant was placed surgically more distally in the area of the missing mandibular first molar with a cantilever effect and a crest width of >12 mm in a 59-year-old patient who had a history of bruxism. Fracture of abutment is a common complication in implant was placed in area with high occlusal forces. Inability to remove the broken abutment may most often end up in discarding the implant. Adding one more dental implant mesially to the previously placed implant, improvisation of technique to remove the broken abutment without sacrificing the osseointegrated dental implant, fabrication with cemented custom-made abutment to replace the broken abutment for the first implant, and the use of the two implants to replace a single molar restoration proved reliable and logical treatment solutions to avoid these prosthodontic complications.

A Split-Mouth Design Comparison for Lateral and Crestal Sinus Lift Techniques with Dental Implants Placements: Short Communication.

OBJECTIVE: The objective of this study is to compare and evaluate the effectiveness of implant placement and patient appraisal for two sinus lift techniques using both crestal and lateral techniques for bilateral sinus left in a split-mouth design. INTRODUCTION: All implants were successfully osseointegrated without any clinical complications or peri-implant radiolucency during the follow-up period of maximum 3 years. METHODS: In terms of outcomes postoperative vertigo showed to be a major concern with the crestal approach, this approach is preferred over the lateral technique because of the reduced time required for the procedure and because it is less invasive. RESULTS: Most patients preferred the crestal approach over the lateral approach due to the delay in implant placement.

Immediate Dental Implant Placements Using Osteotome Technique: A Case Report and Literature Review.

This clinical case describes the effect of the osteotome technique on the osseointegration of a mandibular dental implant in a 42-year-old female patient with dento-alveolar bony defects and to review the literature regarding immediate implant placement using osteotome technique. The amount of bone expansion at the alveolar ridge and the marginal bone resorption from the time of implant placement to one year after the implant's functional loading were recorded clinically. The esthetic outcome for the restored implant (the gingival margin) was achieved one years after the implant's functional loading. The surgical and prosthetic sites for the implant showed no postoperative complications, and no infection or wound dehiscence was recorded during the follow-up period. The osteotome technique is good for the purpose for which it was introduced, and its advantages with immediate implant placement include reduced surgical trauma and a shorter treatment time.
