Biologically oriented preparations in fixed prosthodontics

Abstract

Introduction: The management of soft tissues in fixed prostheses is of high importance, mainly in the aesthetic area. Biologically oriented preparations are intended to manage the emergence profile to seek the best aesthetic and biological results. Objective: The objective of this work is to analyze the literature about BOPT, the protocol that is carried out in the preparation and taking of the impression as well as its advantages and disadvantages. Methods: The search for published articles was carried out using the PubMed and Google Scholar database. Keywords used for the search include “Biologically oriented preparation technique”, “vertical preparation” and “BOPT”. Results: The BOPT technique seeks to improve aesthetics by managing tissue through vertical preparation, exchange of the CEJ and provisionalization. It is a technique with different steps and a large learning curve, however, among its advantages is the possibility of rehabilitating fractured teeth, improving the repreparation of the pieces and improving aesthetics.Conclusions: Having different types of fixed prosthesis preparation gives the clinician the opportunity to choose to seek the best result in the final restoration. The BOPT technique could be the technique of choice when repreparing pillars, seeking better aesthetics or for a fracture.
