objectives : microbial leakage through the implant-abutment (i-a) interface results in bacterial colonization in two-piece implants. the aim of this study was to compare microleakage rates in three types of replace abutments namely snappy, goldadapt, and customized ceramic using radiotracing. materials and methods: three groups, one for each abutment type, of five implants and one positive and ...

objective: vertical bone loss evaluations in the nobel biocare replace® select tapered tm implant system in the human after one-year loading time. materials and methods: this retrospective cross-sectional study was performed on 31 patients (14 men, 17 women; mean age, 60.39 years) receiving 170 implants (mean, 5.48 for each patient) of groovy and non-groovy designs in the nobel biocare replace®...

Background : To compare crestal bone changes after placement of immediate versus delayed dental implant
 Aim and Objective Comparative evaluation in palcement implant: A clinico-radiographical study.
 Methods coparative study was conducted total 20 implant sites patients within the age group 20-60 years comprising both male female visiting Out-patient Department Periodontology Implant...

A highly skilled surgical technic is an important factor for the success of implant. But the heat generation during bone preparation will greatly affect the healing process of bone and prognosis of implant. In this study, the heat occurrence and distribution during bone preparation which performed on an in vitro mandible model (ribs of pig) were considered with the aid of a real-time thermograp...

PURPOSE The aim of this study was to assess the contributions of some prosthetic parameters such as crown-to-implant (C/I) ratio, retention system, restorative material, and occlusal loading on stress concentrations within a single posterior crown supported by a short implant. MATERIALS AND METHODS Computer-aided design software was used to create 32 finite element models of an atrophic poste...

Abstract The present work focuses on the evaluation of polymer, metal and ceramic based biomaterials with particular emphasis success rate these materials till date along merits demerits material system. Currently, search for improved performance is rise biomedical (mainly total hip replacement, THR) applications owing to increase in number orthopedic patients worldwide. clinicians utilized pol...

BACKGROUND Total knee arthroplasty (TKA) is common, effective, and cost-effective. Innovative implants promising reduced long-term failure at increased cost are under continual development. We sought to define the implant cost and performance thresholds under which innovative TKA implants are cost-effective. METHODS We performed a cost-effectiveness analysis using a validated, published compu...

Purpose. Evaluation of the short implant (8 mm in height) long-term prognosis and of the implant site influence on the prognosis. Methods. A longitudinal study was carried out on 121 patients (57 males and 64 females) consecutively treated with 257 implants. 108 implants were short. Results. Four (3.6%) short implants supporting fixed partial prostheses failed. Similarly, three standard implant...

Abstract Due to the material itself and traditional geometric design, short implants have problems of high stiffness, less osseointegrated area, lower long-term reliability in clinical application. In this research, with various porous structures were constructed their biomechanical responses evaluated, including properties, compression capability, stress distribution surrounding bone tissue.
