objectives: fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (chs). the purpose of this study was to compare the fracture strength of implant-supported fixed partial dentures (fpds) with excessive crown height, fabricated from three different materials. mater...

conclusions there are few absolute contraindications for di treatment. as a whole, correct patient selection, and applying standard rules of surgical procedure and di loading would lead to a successful di treatment. results though, there are multiple technique-related or patient-related local and systemic factors, which may interfere with proper osseointegration or compromise the long-term impl...

objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...

peri-implantitis is a state defined as an inflammatory reaction around osseointegrated implants, leading to progressive loss of supporting bone. various treatment methods are suggested in the treatment of peri-implantitis and clinicians have to choose a method over a large number of treatment protocols. lasers have shown promising therapeutic effect in treatment of peri-implantitis. however, so...

objectives: the purpose of this study was to compare the accuracy of implant position transfer and surface detail reproduction using two impression techniques and materials. materials and methods: a metal model with two implants and three grooves of 0.25, 0.50 and 0.75 mm in depth on the flat superior surface of a die was fabricated. ten regular-body polyether (pe) and 10 regular-body polyvinyl...

introduction microbial plaque is the main etiologic factor which causes disease in soft tissue around dental implants. the purpose of this study was to evaluate the effect of plaque on health indicies of soft tissue around dental implants. methods and materials 45 patients with 211 dental implants were examined clinically for four years after prosthodontic treatment. plaque index and health ind...

introdouction: although highly desirable outcomes and longterm survival of dental implant treatments are well documented, implant failures still occur due to various reasons. several risk factors may impair implant survival including implant dimensions (length, diameter, and implant design), procedures, local bone density at the implant site, and patient-related risk factors such as age, smokin...

BACKGROUND AND AIM: Information gathered from patients about dental implants is often incomplete and scattered. The aim of the present study was to measure the level of this information and the attitudes of patients seeking dental implants.METHODS: In the present cross-sectional descriptive-analytic study, 248 people were employed. To discover the level of knowledge and attitudes in dental impl...

background and objective: the concept of immediate occlusal loading with dental implants offers several advantages. in this research, the effect of type of restoration on osseointegration rate of dental implants was histologically evaluated. materials and methods: three months prior to implantation, the lower premolar teeth of 15 dogs were extracted. then, 3 to 4 maestro™ implants were placed i...
