Spatial Guidelines in Systemic Restoration of Teeth: Case Report

Abstract

In the systematic restoration of teeth, it is important to have reliable spatial guidelines, which can be used to reproduce the original anatomical shape of the teeth. Restoring the dentition and bite in the primary vertical dimensions and movements, normalizing the occlusion and balance of the chewing muscles, optimizing the position of the heads in the joints and posture will follow the correct restoration of the anatomical shape of teeth according to a certain system algorithm. In the direct restoration of teeth in a free hand technique, the leading spatial guidelines are the size and shape of the tooth crown, the outer surface of the preserved enamel, the cervix of the tooth, the topography of the dental tissues (dentinoenamel junction and tooth cavity). In indirect restoration, there are no specific spatial guidelines in teeth that prepared for fixed prostheses, therefore, for laboratory modeling of teeth and bite, the leading spatial guidelines are the position of the heads in the joints and the movements of the lower jaw with the modeling of the teeth in the articulator. For both approaches in determining the bite (due to the anatomical shape of the teeth and the position of the lower jaw), the result should be a functional occlusion with all its inherent features.
