Evaluación de sobredentaduras mandibulares implanto-retenidas confeccionadas con técnica Rehabilitación Oral M/Prótesis, Facultad Odontología, Universidad de Concepción, en pacientes del Servicio Salud Bío-Bío

Abstract

Health care services show interest in establishing rehabilitation protocols with mandibular overdentures retained on two implants, but they require scientific evidence evaluated with reliable instruments.

Objective

To evaluate masticatory performance, retention and therapeutic satisfaction of patientswith a model rehabilitation protocol for implant-retained overdentures.

Materials and methods

This study was conducted between the Faculty of Dentistry, University of Concepción (FAO UDEC) and Bío Bío Health Service(SS-Bío Bio). Fourteen patients, selected users of Bío Bío Health Service, Los Angeles, received implant-overdentures using a protocol of the Oral Rehabilitation Prosthesis Program (ROMPE FAO UDEC). Two Neodent™ implants (3.75 × 11 and 13 mm) were installed in each patient and connected with early loading. Before and after installing and connecting the implants, (0, 30 and 60 days), therapeutic satisfaction was assessed using the ROMPE FAO UDEC graduate program questionnaire. Retention was measured with a Force Gauge Dynamometer, and masticatory performance was quantified with a peanut screening test. Data were processed with SPSS 16.0 program and Kolmogorov-Smirnov test and t- test were used. Significance was set at P < .05.

Results

Masticatory efficiency significantly increases after connectingthe implants. Therapeutic satisfaction with the prosthesis and the tensile strength are highly significant.

Conclusions

These results coincide with the vast majority of published studies. It can be scientifically argued that the ROMPE FAO UDEC, SS Bío Bío overdenture protocol is a reliable alternative.
