Selección de esquemas oclusales en prostodoncia fija y removible: revisión de la literatura

Abstract

Introduction: Currently, there is no criterion that recommends the application or definitions of an occlusal scheme in the different prosthetic treatments available, so it is necessary to review the literature describing these schemes. Objective: To propose a list of recommendations for the selection of the appropriate occlusal scheme according to each type of prosthetic design with both tooth-supported and implant-supported rehabilitation. Materials and methods: Literature review. All epidemiological designs with at least one prosthetic design with evaluation of occlusal schemes and with at least one restoration or prosthesis were included. A combination of controlled vocabulary and free terms in the different databases was used to identify the studies, which were chosen with two authors independently. Finally, an evaluation of the methodological quality of the studies was performed. Results: Seven articles were included. Most of the studies were randomized clinical trials. Data for 626 patients were included. The studies included patients with either fixed partial, total removable or hybrid prostheses. The included clinical trials are at high risk of bias due to non-blinding of patients and unclear concealment and generation of the randomized sequence. While the included observational studies presented an unclear risk of bias due to the non-explanation of the measurement of the outcome. Conclusion: After reviewing the available literature, no descriptions of the occlusal schemes in all types of oral rehabilitation were found, therefore, it is not possible to make a recommendation to rehabilitate each case with a specific occlusal scheme.
