Guia canina como chave de oclusão: revisão de literatura

Abstract

The canine guide is important for an ideal occlusion and, thus, for the proper functioning of the stomatognathic system. Dentistry has been growing and establishing itself in the area of restorative dentistry, being a simple treatment to be performed and conservative, with good indication for cases of reestablishment of guides. The objective of this work is to discuss the importance of the canine guide and its restoration through direct restoration with composite resin. A bibliographic survey was made in the main databases using the keywords “dental occlusion” (dental occlusion); “Canine tooth” (cuspid); and “dental resins” (resins, synthetic). The canine tooth is anatomically more favorable to receive occlusal forces because it has a long and robust root and, when performed, the lateral movement of the mandible occurs; the canines come into contact, allowing the posterior teeth to be dislocated, thus giving rise to the canine guide. This provides adequate dissipation of forces to the posterior teeth and consequently reduces the force action of the masticatory muscles, when the canine guide is absent, it can be reestablished through restorative dentistry. It is necessary that the professional has correct knowledge about dental occlusion, including the occlusion keys to be able to diagnose and treat malocclusions on a daily basis in his office.
