Occlusal Contouring Using CAD/CAM - State-of-the-Art Technology
The methods and materials for fabricating restorations have greatly developed in the past decades. The exponential increase in the performance of computer systems has resulted in the digital fabrication of occlusal surfaces using the computer becoming widespread in practices and laboratories. CAD programmes for contouring the morphology of restorations have been considerably improved and provide various possibilities for threedimensional visualisation. Systems that operate mainly by reducing material will in future be complemented by additive systems, which will greatly extend the possibilities of CAD/CAM systems. Depending on the type of material used, e.g. porcelain restorations, deep fissures on the occlusal surface lead to an unnecessary weakening of the structure. Current systems and occlusal surfaces fabricated with the aid of these systems can be assessed as suitable for practical application.
