The data revealed significant displacement between the SCP and ICP of the condyles (displaced most frequently inferior (down) and posterior (distal)) and substantially increased frequency and magnitude of displacement of the dental arches (with posterior premature occlusal contacts, increased overjet, decreased overbite, midline differences, and occlusal classification changes) in symptomatic subjects. The initial occlusal contact, DAD, and condylar displacement were evaluated for frequency, direction, and magnitude of displacement between the SCP and ICP. A total of 1 192 sets of dental casts collected from asymptomatic and symptomatic populations were articulated in the SCP. The objective was to evaluate the three-dimensional nature of DAD and CD between the seated condylar position (SCP) and the intercuspal position (ICP) and to compare results derived from large deprogrammed asymptomatic and symptomatic populations. 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.

We hand pick programs that we know can open or otherwise handle each specific type of file.
We spend countIess hours researching varióus file formats ánd software that cán open, convert, créate or otherwise wórk with those fiIes.įor example, in the file name winmail.dat, the file extension is dat.
