Clinical applications of the etched metal retainer

This article presents the treatment of several patients directed at the prevention of periodontal disease and restoration of an occlusion from an eating disorder. The disruption of the harmony between the anterior and posterior determinants of occlusion can lead to the loss of teeth. The lack of anterior guidance can create a molar-guided occlusion producing unfavorable occlusal interferences with destructive balancing side prematurities. Conversely, if the posterior teeth are permitted to drift into unstable occlusal relationships, the posterior dentition would develop an irregular guidance despite a suitable anterior guidance. The goal of the profession is preventing occlusal deterioration or disharmony between the anterior and posterior occlusal determinants and restore compromised occlusions when necessary. Etched metal retainers were fundamental to the treatment of specific patients while patient selection and perceptive tooth preparation were essential for success.
