Efeito imediato do reparo ou troca das próteses mucoso suportadas maxilares e mucoso suportadas implanto retidas mandibulares na funcão mastigatória, satisfação e qualidade de vida do paciente

Abstract

The aim of this study was to evaluate the effect of replacement and repair of unsatisfactory maxillary mucosa supported and mandibular implant retained overdenture on the masticatory function, quality of life and satisfaction of completely bimaxillary edentulous patients. Thirteen completely bimaxillary edentulous patients rehabilitated with complete mucosa supported maxillary dentures and mandibular implant retained overdentures had their dentures assessed according to esthetic physical and functional criteria. Three patients required only repair to dentures and 10 patients needed to have them replaced. The clinical and laboratory procedures were standardized and performed by a single operator. Laboratory tests for analyzing masticatory performance were performed by means of masticating the food simulator Optocal for 40 cycles. The index was obtained by calculating the percentage of reduction in the mean geometrical diameter of the masticated particles. Masticatory ability, satisfaction with dentures and quality of life related to oral health was evaluated by means of questionnaires. The tests were performed and questionnaires applied before, and one month after the patient had adapted to the new dentures. The masticatory performance data were statistically analyzed by means of the paired Student s-t test. For the other evaluations, the Wilcoxon test was used (a=.05). There was no statistically significant improvement in masticatory function before and after denture replacements and repairs (P=0.53). Masticatory ability presented no statistically significant difference, since the majority of patients had considered their masticatory function satisfactory. There was a statistically significant improvement in satisfaction with the dentures, stability, retention and esthetics, and as regards the questions with reference to quality of life related to oral health: retention of food under the dentures and difficulty with chewing certain foods. Within the limits of this study, it could be affirmed that the potential for grinding food and masticatory ability did not improve immediately after changing or repairing the unsatisfactory dentures. However, the patient s satisfaction and aspects of quality of life improved significantly after denture replacement and repair.
