Platform switching on wide-diameter external hex implants: a finite element analysis
OBJECTIVES The objective of this work was to use finite element analysis to compare the effect of forces coming to bear on abutments 4.1 or 5.0 mm in diameter connected to a 5.0 mm implant (i.e. with or without platform switching). STUDY DESIGN A 3D CAD model of a 5 x 11.5 mm external hex implant was developed, complete with a connection screw and either of two abutments, one 4.1 and the othe...
متن کاملbiomechanical effects of platform switching in two different implant systems: a three-dimensional finite element analysis.
the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...

متن کاملBiomechanical finite element analysis of small diameter and short dental implants: extensive study of commercial implants.
In recent years, mini and short dental implants have become increasingly popular as treatment alternatives for patients in whom the bone is unsuitable for a standard implant. As yet, no detailed scientific analysis of the mechanical and biomechanical impact of the reduced diameter and length of these implants has been published. We analysed 21 commercially available implants (13 mini, eight sho...
متن کاملبررسی اثر Platform Switching در توزیع تنش‌های استخوان کرستال اطراف ایمپلنت‌های دندانی 3iبه روش FEA) Finite Element Analysis)
سابقه و هدف: در سال‌های اخیر نظریه Platform Switching با استفاده از اجزای پروتزی با قطر کمتر از گردن ایمپلنت، به منظور کاهش تحلیل استخوان کرستال اطراف ایمپلنت‌های دندانی ارائه شده است. برخی از محققین معتقدند که با کمک این طراحی می‌توان تجمع تنش را در اینترفیس استخوان- ایمپلنت کاهش داد. بنابراین هدف از مطالعه حاضر بررسی و مقایسه تنش‌ها در اینترفیس استخوان کرستال-ایمپلنت و نیز اینترفیس ایمپلنت- ا...
