![]() While large population studies associate dental arch displacement (DAD), especially laterally, with symptoms, mandibular condyle displacement (CD) resulting from DAD has not been targeted as possibly etiologic in the production of common muscle contraction headache (CMCH) and temporo-mandibular dysfunction (TMD). In the present paper the stresses from an articulator TMJ modelled as a bronze sphere into a cylindrical steel cavity are analyzed by two methods, first applying the Hertzian contact theory and then numerically, by means of finite element analysis using the simulation module in CATIA.Īrticulated dental cast analysis of asymptomatic and symptomatic populationsĭental instrumentation has long provided insight into the mechanism of musculo-skeletal function of the gnathic system. ![]() The articulator is essential as it replicates the basic motions of the upper and lower mandibles, both revolve and translational motions. ![]() CONSIDERATIONS UPON CONTACT STRESS MODELLING IN DENTAL ARTICULATOR PAIRSĭirectory of Open Access Journals (Sweden)įull Text Available A dental articulator is a mechanism which simulates the temporo-mandibular joint.
