Impacto do protocolo mandibular implanto-suportado na função mastigatória, estado nutricional e qualidade de vida - estudo clínico retrospectivo

Abstract

Background: Clinical problems are commonly reported by users of mandibular dentures, such as inability to comminute foods, decreasing on self-confidence, quality of life, social contact and personal satisfaction. Purpose: the aim of this study was to measure the impact of the use of mandibular implant fixed denture with reduced number of implants on chewing performance, nutritional status and quality of life. Materials and Methods: a clinical retrospective study involving edentulous patients that received installation of mandibular implant-supported prosthesis and new upper denture. The masticatory performance, quality of life and nutritional status before and after installation of the new prostheses (CD = before treatment, ISP30 = 30 days, and ISP150, five months after the installation of new prostheses) were measured. Masticatory performance was assessed by the colorimetric method; the quality of life was recorded using the Test Impact Profile-14 Brazil (OHIP-14Br) and the nutritional status determined by nutritional markers through hematology exams. Data were analyzed using of one-way Anova, Pearson correlation between masticatory performance and quality of life and Pearson correlation between masticatory performance and nutritional indexes. Results: significant improvement of quality of life index (p<0,05) was observed for masticatory performance (p< 0,05) after PTIS150. No significant difference was found between the evaluation times for nutritional markers (p< 0,05). Low correlation was found between masticatory performance and quality of life (CD: p = 0,187, ISP150: p = 0,732). Conclusions: positive impact of quality of life and masticatory performance was found, however no significant improvement was found for nutritional indexes.
