20 I I clinical report _ crowns _The creation of a functional occlusion is the goal of any prosthetic treatment and can be very difficult to achieve in cases of full-mouth rehabilitation,especially in the case of temporo- mandibular joint (TMJ) dysfunction. In these clinical situations, pro- visional restorations are an excellent diagnostic instrument. Aesthetics, phonetics and function, after evaluation and ac- ceptance by the patient after try-in of the provi- sionalrestorations,should be accurately transferred to the final restorations to ensure the same clinical success.1–2 The aim of this study is to demonstrate the manner in which individual movement charac- teristics of a patient’s TMJ can be included in traditional CEREC temporary crown fabrication. New occlusal relations need to be created with respect to the individual characteristics, such as mandibular and hinge axis positions, Bennett and sagittal angles. The incorporation of occlusal plane formation principles is essential to improve and ease a patient’s adaptation to new occlusal relations, as well as to reduce the probability of TMJ dysfunction. However, CEREC software does not enable the inclusion of TMJ parame- ters.
