An upper and a lower poured stone model were created by taking impression of fully dentate male (fifty years old) participant. The aim of the current study is to develop a novel method to investigate the accuracy of 3D scanners and digital articulation systems.

PMID:25177664ДЄ Novel Methodology to Validate the Accuracy of Extraoral Dental Scanners and Digital Articulation Systems.Д®llakwa, A Elnajar, S Littlefair, D Sara, G Also, a brief note on virtual reality haptic system has been highlighted along with newly developed touch enabled virtual articulator. It is the purpose of this article to present the concepts and strategies for a future replacement of the mechanical articulator by a virtual one. The virtual articulator is one such application in prosthetic and restorative dentistry based on virtual reality that will significantly reduce the limitations of the mechanical articulator, and by simulation of real patient data, allow analyses with regard to static and dynamic occlusion as well as to jaw relation. Virtual reality is a computer based technology linked with the future of dentistry and dental practice.

Displacement of the mandibular condyle may be an etiologic factor in CMCH and dysfunction of the temporo-mandibular joint. Transverse condylar displacement, commonly presenting with dental cross bite, may be associated with CMCH and TMD. The data support the concept of increased DAD and CD with dysfunction. These discrepancies were statistically significant and clinically significant. 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 1Гўв‚¬вЂ°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.ДЄrticulated dental cast analysis of asymptomatic and symptomatic populationsДental 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.
