Esthetic & Function: The 4D Solution A Clinical Evaluation
Journal Title: Modern Approaches in Dentistry and Oral Health Care - Year 2018, Vol 2, Issue 3
Abstract
Since the beginning of dentistry, prosthodontists are trying to understand jaw motion and its impact on occlusion. This medical approach is dedicated firstly to achieve a diagnosis and then to be able to produce dental prosthesis with fully bespoke anatomies for each patient. Scientific literature is rich of technics invented to record jaw motion, especially between 1960 to 1990. Those devices were globally time consuming and required deep familiarity with occlusion making its use reserved for specialists [1-3]. Clinicians and researchers filled the science with great knowledge about chewing patterns, condylar movements and jaw motion. But they were limited by technology when it came to use those informations for prosthetics production. Articulators reproduces jaw movements with a mechanical behavior, they can be programmed in order to increase the precision, but again, this action is time consuming and rather elitist. For a few decades now, Cadcam dentistry resulted in the ability to build prosthetics using 3D virtual models and which are then milled or printed. But jaw motion was still an approximation and do not reflect the true patient’s jaw movements. This will remain as long as virtual articulators stays digital copycats of mechanical ones bearing the same operating logics. The aim of this presentation is to explain and evaluate a new approach based on a digital record of the jaw motion: 3D models are animated just as the patient’s function replicating the exact same jaw movement over time, this is why it is called the 4D Cadcam technology. To be long lasting, our prosthetic restorations must be functionally integrated, esthetic and perfectly correlated with the patient’s function
