Accuracy and precision of occlusal contacts of stereolithographic casts mounted by digital interocclusal registrations.

Statement Of Problem: Little peer-reviewed information is available regarding the accuracy and precision of the occlusal contact reproduction of digitally mounted stereolithographic casts.

Purpose: The purpose of this in vitro study was to evaluate the accuracy and precision of occlusal contacts among stereolithographic casts mounted by digital occlusal registrations.

Material And Methods: Four complete anatomic dentoforms were arbitrarily mounted on a semi-adjustable articulator in maximal intercuspal position and served as the 4 different simulated patients (SP).

Effect of occlusal vertical dimension on lip positions at smile.

Statement Of Problem: In complete mouth reconstructive dentistry, the occlusal vertical dimension may be increased to provide adequate restorative space or to improve esthetics. The effect of increasing the occlusal vertical dimension on the smile is not well understood.

Purpose: The purpose of this study was to evaluate the effect of increasing the occlusal vertical dimension on the dimensions of the smile.
