Custom anatomical abutment: a review study

Abstract

To describe the main benefits of using personalized ceramic abutments, when used in implants with unsatisfactory positions, presenting aesthetic and functional results. The present work was a qualitative, exploratory and descriptive review of narrative literature, which evaluates the knowledge produced in previous research, highlighting concepts, procedures, results, discussions and conclusions on the proposed theme. Currently, there is a great demand, both through the patient and through the professional, to achieve an aesthetic and functional result through rehabilitation in dentistry with implant-supported prostheses. Both seek a harmonious result with the patient's dental arch, in addition to returning their functional capacity. Therefore, it is extremely important to choose the abutment, where it should allow a similarity of color and translucency in relation to the remaining tooth structure. For a long time, titanium abutments were considered the best alternative in cases of rehabilitation, but a negative aspect has always been the fact of their interference in the aesthetic result, inducing a visual change in the color of the overlying gum. To solve these problems, the ceramic pillars appeared, offering discretion; associated with the simplicity of the installation technique, result predictability and mechanical resistance, which already existed with the metal pillars.
