Objective. To use a musculoskeletal model and simulation of running to examine: (1) the in ̄uence of two commonly prescribed treatments for patellofemoral pain (vastus medialis oblique strengthening and orthoses) and (2) the functional signi®cance of timing di€erences between vastus medialis oblique and vastus lateralis on lateral patellofemoral joint loads. Design. A three-dimensional musculosk...

OBJECTIVE To use a musculoskeletal model and simulation of running to examine: (1) the influence of two commonly prescribed treatments for patellofemoral pain (vastus medialis oblique strengthening and orthoses) and (2) the functional significance of timing differences between vastus medialis oblique and vastus lateralis on lateral patellofemoral joint loads.

This paper describes a computational investigation on the response of thin wall structures due to dynamic compression loading. In this paper, the tubes subjected for both direct and oblique loading. Several different cross-sectional structures have been studied to specify the best one. Initially the tubes were subjected to direct loading, and then the tubes were subjected to oblique loading. Af...

Biomechanical influences on bone structure play an important role in the longevity of bone around an implant. The quantity and direction of applied force influence the implant and cause deformation of the bone. FEA was used to analyze the changes in the bone on loading the implant with orthodontic force in oblique and vertical directions and orthopedic force. The Mini-implants used in the prese...

Distal extension removable partial denture (RPD) can cause stress on supporting hard tissues, which may lead to harmful effects. The purpose of this study is to investigate the pattern of these stresses over the residual alveolar ridge and alveolar bone around the abutment teeth by distal extension conical crown retained te lescop ic dentures (CCRTDs) with different taper angles using three dim...

OBJECTIVE The aim of the study is to evaluate the stress distribution in tooth supported 5-unit fixed partial denture (FPD) having tooth as pier abutment using rigid and nonrigid connectors respectively, under simultaneous and progressive loading. MATERIAL AND METHODS The three-dimensional (3D) finite element program (ANSYS software) was used to construct the mathematical model. Two 5-unit FP...

Background and Aim: Oral bacteria can proliferate in the implant-abutment interface (IAI) and cause inflammation in the peri-implant tissues and adjacent bone. This study aimed to assess the effect of zirconia and titanium abutments on the microleakage of the IAI under oblique cyclic loading conditions. Materials and Methods: In this in-vitro study, 12 implant-abutment assemblies with zirconia...

Near side impact crashes – especially pole impacts – have the potential to induce antero-lateral oblique loads to the chest. Current side impact dummies and most laboratory experimental studies have been designed to assess direct lateral impacts. A recent analysis of real world crashes indicated that the human chest experiences oblique loading in side impact crashes – in particular crashes into...

OBJECTIVES 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. MATERIALS AND METHODS 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...
