|Glaucoma is an eye disease which is caused by abnormal high IOP (Intra Ocular Pressure) in the eye. The use of implants is increasing in these days in order to treat the glaucoma. However, though conventional implants have a capability of pressure regulation, they cannot maintain IOPs desired for di erent patients. To solve these problems, it is needed to develop a new implant which is capable...
Implant-supported fixed prostheses are a highly successful treatment option for replacing missing teeth, offering improved esthetics, function, and patient satisfaction. Design considerations play crucial role in achieving optimal outcomes. Implant distribution angulation should be carefully planned to ensure balanced load biomechanical stability. Occlusal vital minimize mechanical complication...
Screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. Screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. The purpose of this study is to descr...
PURPOSE Micromotion at the implant-abutment level has been reported to be a major determinant of longterm implant success, as technical problems ranging from screw loosening to screw fracture may occur as a consequence of excessive micromotion. MATERIALS AND METHODS Following published standards, implant-abutment assemblies were fixed in a universal testing machine at a 30-degree angle. A cyc...
OBJECTIVE To determine the orbital tolerance of a microporous implant fitted with an integrated stainless steel post and the enhanced motility associated with magnetic coupling of the prosthetic and the implant in a rabbit model. METHODS Six New Zealand white rabbits underwent primary enucleation with implantation of a 12-mm microporous polyethylene implant with a 2 x 3-mm stainless steel pos...
هدف:بررسی نتایج عمل تخلیه چشم ((evisceration و کارگذاری implant در بیماران مراجعه کننده به کلینیک مرکزی شهر در سالهای 1388و 1389 روش مطالعه:این مطالعه که از نوع توصیفی مقطعی بوده در 22 بیمار مراجعه کننده به کلینیک مرکزی شهر که تحت عمل evisceration با روش implant گذاری نوین قرار گرفته اند انجام شده است. بیماران بعد از ثبت اطلاعات دموگرافیک و سوابق چشم پزشکی و اطمینان از عدم دید کامل آنها(nlp) ...
Painful arthritis of the elbow joint has long been a challenging problem. Elbow arthroplasty has emerged as viable treatment method for many patients. Implant design and surgical technique have evolved to provide more predict-able symptom relief without compromising function. Elbow arthroplasty can now be used to treat a wide variety of conditions, including osteoarthritis, rheumatoid arthritis...
The design of a custom hip implant can be broken up into several distinct phases which can be carried out by separate toolkits which specialize in the service needed for each stage. We describe a client-server environment in which multiple experts can collaborate in the implant design process and shape optimization, while computations for modelling the femur, simulating loading conditions, and ...
This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...
PURPOSE Implant restoration of the partially edentulous patient has become highly predictable. The scientific information on the specifics of restorative designs and their influence on the long-term outcome is sparse. The main objective of this systematic review was to determine what scientific evidence exists regarding the influence of prosthodontic design features on the long-term outcomes of...
