Stress distribution in the temporomandibular joint after mandibular protraction: A 3-dimensional finite element study. Part 2

Abstract

This study indicates that increasing the construction bite height might give more favorable stress patterns in the TMJ, thereby improving the condylar response to functional appliances. The findings of this preliminary study need to be investigated in an animal model and in humans before deriving clinical implications.

Stress distribution in the temporomandibular joint after mandibular protraction: A three-dimensional finite element study

“…7,8 This could be attributed to the use of recent version of software with greater sophistication and advanced CAD modeling capabilities. The quality of pattern of stresses in the present study was similar to that in the studies by Gupta et al 7,8 who used IDEAS software and ANSYS 8.0 version, though this study used MIMICS software, which is believed to be more accurate for the CAD modeling procedure along with ANSYS 13.0 version for finite element analysis.…”

“…A possible limitation to the present study could be that only the left side of TMJ was modeled; thus, all results are based on the characteristics of a single subject. FEM studies in the past 7,8 suggested that increasing construction bite heights was found to generate more favorable stress patterns in TMJ, which could be corelated with a possible improved condylar response to functional appliance treatment. There was availability of an experimental study by Noro et al, 21 wherein the similar hypothesis was investigated.…”

“…This could indicate a possible improved condylar response to functional appliance treatment. 8 Inconsistent opinions have been recorded regarding the vertical component and horizontal advancement of the mandible. Andresen 10 suggested protrusion of the mandible to neutro-occlusion and keeping the bite within the freeway space.…”

“…[1][2][3][4][5][6][7][8] Finite element method (FEM) studies on human temporomandibular joint (TMJ) are being increasingly carried out to elucidate the biomechanical reactions of functional appliances. FEM is an in vitro, highly sophisticated, and noninvasive method.…”

“…In the second phase of treatment, fixed orthodontic appliances are used to refine occlusion (1,9). The responses of the temporomandibular joints (TMJs) treated using this method are controversial, which has led to the conduction of studies using the three-dimensional finite element method (10) as well as analyses in groups of experimental animals (11) or humans beings (1)(2)(3)(4)(5)(6)(7)(8)(9).…”
