“…The compressive stresses were located in the anterior and anterosuperior aspects. These results can be correlated with Tanaka et al 4 who conducted a similar FEM study of mouth opening. As the horizontal activation increased, the maximum tensile stresses increased posteriorly in both HA2 and HA3.…”

Objective: To evaluate the stress patterns in temporomandibular joint (TMJ) during mandibular protraction at different horizontal advancements with constant vertical height in a construction bite using a three-dimensional finite element method. Materials and Methods: A three-dimensional computer-aided model was developed from the magnetic resonance imaging (MRI) of a growing boy (age 12 years) using MIMICS software (version 7.0, Materialise, Leuven, Belgium). Stresses with constant vertical opening of 5 mm changing the sagittal advancements from 0 mm to 5 mm and 7.5 mm were recorded. Differences in magnitude and pattern of stresses were compared. Results: The tensile stresses in the posterosuperior aspect of the condylar head and on the posterior aspect of the glenoid fossa migrated posteriorly with increased bite advancements. The location of tensile stresses changed in the condylar head and fossa on mandibular protraction of 5 mm to 7 mm. Conclusion: This study indicates that larger horizontal advancements of construction bites may not be favorable for tissues of TMJ. Clinical application necessitates study on an animal model.

The aim of this study was to investigate stresses resulting from different thicknesses of grit blast (GB) and micro arc oxidized (MAO) treated layers at the interface between temporomandibular joint (TMJ) implants and bones using three-dimensional (3D) fi nite element models. Several studies have investigated fi nite element models for TMJs, but few have examined a model for TMJ implants with treated layers. The maximum stresses in the bone occurred at the position of the fi rst screw. Data analysis indicated a greater decrease in this stress in the case of using TMJ implants with MAO treated layers, and the stresses decreased with increasing layer thicknesses. Results confi rmed that the treated layers improve biomechanical properties of the TMJ implants and release abnormal stress concentration in them. The results of this study off er the potential clinical benefi t of inducing superior biomechanical behavior in TMJ implants.

A Call to Action for Bioengineers and Dental Professionals: Directives for the Future of TMJ Bioengineering

Abstract-The world's first TMJ Bioengineering Conference was held May 25-27, 2006, in Broomfield, Colorado. Presentations were given by 34 invited speakers representing industry, academics, government agencies such as NIH, and private practice, which included surgeons, engineers, biomedical scientists, and patient advocacy leaders. Other attendees included documentary film makers and FDA officials. The impetus for the conference was that the field of TMJ research has been lacking continuity, with no open forum available for surgeons, scientists, and bioengineers to exchange scientific and clinical ideas and identify common goals, strengths, and capabilities. The goal was thus to plant the seeds for establishing a forum for multidisciplinary and interdisciplinary interactions. The collective wisdom and interactions brought about by a melting pot of these diverse individuals has been pooled and is disseminated in this article, which offers specific directives to bioengineers, basic scientists, and medical and dental professionals including oral and maxillofacial surgeons, pain specialists, orthodontists, prosthodontists, endocrinologists, rheumatologists, immunologists, radiologists, neurologists, and orthopaedic surgeons. A primary goal of this article was to attract researchers across a breadth of research areas to lend their expertise to a significant clinical problem with a dire need for new talent. For example, researchers with expertise in finite element modeling will find an extensive list of clinically significant problems. Specific suggestions for TMJ research were presented by the leading organizations for TMJ surgeons and TMJ patients, and further research needs were identified in a series of group discussions. The specific needs identified at the conference and presented here will be essential for those who endeavor to engage in TMJ research, especially in the areas of tissue engineering and biomechanics. Collectively, it is our hope that many of the questions and directives presented here find their way into the proposals of multidisciplinary teams across the world with new and promising approaches to diagnose, prevent and treat TMJ disorders.
