Resultados clínicos de reabilitações mandibulares totais fixas sobre três implantes

Abstract

The aim of this study was to retrospectively analyze the clinical outcome of a of a complete fixed mandibular prosthesis supported by three implants with tilted distal implants and to evaluate the patient satisfaction. Materials and methods: Fifteen patients (10 women and 5 men) were included in a retrospective investigation with a mean of 11.2 months. Periapical radiographs were digitized to measure bone loss. To assess patient satisfaction with the prosthesis was applied a questionnaire composed of 4 questions about mastication, satisfaction, retention and aesthetic of the prostheses through the use of a visual analog scale (VAS). To verify the interference of treatment on quality of life of patients was used the questionnaire OHIP14br. Descriptive statistics and Mann-Whitney Test were used. Results: The survival rate of the implants was 97.77% and prosthesis survival rate was 93.33%. It was observed 9 loosening of screw torque. No other complications were observed. 73.33% of the prosthesis was immediately loaded and 36.66% of distal implants received angled abutments. The bone loss ranged from 0 to 2.89 mm with median 0.50 mm. Straight implants had a higher bone loss than the tilted implants (p<0.001).Mean bone loss was 1.64 ± 0.77 mm for the straight implants and 0.37 ± 0.56 mm for tilted implants. All patients reported contentment with the aesthetic and retention of the prosthesis. The masticatory ability was considered adequate by 86.67% and 93.34% of interviewed patients reported satisfaction with prosthesis. The result of applying the OHIP-14Br showed that treatment resulted in a compromised of patients quality of life next zero. Conclusions: A complete fixed mandibular prosthesis supported by three implants with tilted distal implants may be an alternative for implant treatment to an edentulous patient.
