Técnica de All-on-4 como opción terapéutica en la rehabilitación mandibular completacomplicaciones técnicas, biológicas e índice de satisfacción de los pacientes

Abstract

Introduction: Full-arch rehabilitations are limited by the anatomical structures of the maxillas, so different techniques have been proposed for the placement of implants. The All-On-4 concept allows for full-arch rehabilitation with four implants, which will be placed near anatomical structures in patients with severe bone resorption, avoiding additional surgeries. Material and methods: The study design is an observational, descriptive, retrospective and transversal study, which gathered 12 patients: 6 patients treated with the All-On-4 protocol (Group 1) and 6 patients with a hybrid prostheses supported by 6 implants (Group 2). The variables analyzed were: Treatment type; Bleeding on probing; Marginal bone loss; Grade of satisfaction; Biological complications and mechanical complications; Gender; Age. Results: The most important variables showed that Bleeding on probing was slightly higher for Group 1. Marginal bone loss was higher for Group 2. Patients were all satisfied with both treatment options, but the results were higher for Group 1. Conclusions: The global satisfaction index is high in both groups, which rates both treatment options as very positive. There is no relation between gender, age or treatment option and the level of satisfaction. A correlation cannot be made between the treatment option and marginal bone loss or bleeding on probing.
