Objective The aim of this study is the evaluation of the temporomandibular joint stress distribution during the use of a Mandibular Advancement Device.
Materials and methods This study is made using Finite Element Method (FEM). Dental casts, advancement bite, CBCT and MRI were taken in a 27-year-old woman. A Somnodent device was scanned and associated with a three-dimensional cranium.
FEM analysis was made using ANSYS software with 1 and 2 mm of advancement.
Results The articular disc showed values range between 0.099-6.39 and 0.5-2.02 MPa for an advancement of 1 and 2 mm respectively. The condyle load distribution showed values range between 0.0037-7.50 and 0.0020-10.0 MPa for an advancement of 1 and 2 mm respectively.
Conclusions Values obtained are significantly lower than limit values of the condyle and articular disc. Slight mandibular advancement can be consider a safe procedure even for the long period and should not cause permanent side effects.
