Utilização de um sistema de apoio à decisão clínica na reabilitação com implantes dentários e análise dos resultados clínicos

: SAC Assessment Tool

Abstract

Introduction: the International Team for Implantology developed the SAC Assessment Tool to categorize the degree of risk and complexity of implant-supported rehabilitations. The objectives defined for this investigation focused on: the analysis of the application of this tool in the clinical cases performed; the study of the relationship between each variable and the tool’s final result; the analysis of clinical results, particularly success/survival rate and mechanical and biological complications of the rehabilitation. Materials and Methods: observational, longitudinal retrospective study. All variables recorded by the SAC Assessment Tool and clinical outcomes in patients with implant-supported prosthetic rehabilitations performed in a University Dental Clinic were analyzed. The data collected was subjected to descriptive and inferential statistical analysis. Results: data from the surgical evaluation of 78 patients (131 edentulous areas) was analyzed, 38 of these also had prosthetic evaluation (58 edentulous areas). Surgical follow-up time: 8 months. Most patients were female, 46-65 years old, healthy, with medium-high expectations, sufficient oral hygiene, no smoking habits, and adequate access to rehabilitation. Mostly single unit rehabilitations were performed, without esthetic risk, with conventional loading protocol and screw-retained retention. Most of the surgical evaluations presented a simple and advanced degree of difficulty, and the prosthetic ones a simple degree. Most of the variables in the surgical evaluation and clinical results showed a statistically significant relationship with the final outcome of the SAC Assessment Tool, while the same wasn’t true for the prosthetic evaluation. Conclusion: the SAC Assessment Tool is very important at assessing implant-supported rehabilitations because of its comprehensive categorization of the risk factors involved. The variables that showed a significant relationship with the final result of the SAC Assessment Tool demonstrate the importance of its inclusion in this tool. The final result of the assessment with this tool is related to the clinical outcome of the treatment.
