Assessing the Reproducibility of Electronic Devices Aimed at Replacing the Mechanical Pantograph

 

Introduction:

Treating complex cases requires the precise capture of specific records. The conventional workflow of these types of cases includes impressions, finding a repeatable position of centric relation (CR), and recording border movement to create a diagnostic wax-up for definitive restorations. An accurate facebow to orient the maxillary cast on an articulator, and a repeatable centric jaw relation record to orient the mandibular cast with the maxillary, have been the long-used analog data acquisition in restoring occlusion. Recording the border movements of the mandibular jaw is an additional but very important important step to help build functional occlusion and decrease the number of interferences, that prevent the goal of harmony between form and function. The use of a pantograph and a fully adjustable articulator can be used to help achieve this goal. Digital dentistry allows for improved accuracy  or the records and laboratory phases of fabricating restorations. Newer mandibular tracking devices that utilize a digital workflow are considered as an alternate to the mechanical means.

The purpose of this poster is to analyze the use of the Cadiax Compact II and the Modjaw mandibular jaw tracking devices during border movements and assess their reliability in clinical practice.

Null Hypothesis: There is no significant difference between the Cadiax Compact II and Modjaw technology in regard to the reproducibility of the condylar readings.
