Qualidade de vida de pacientes edêntulos reabilitados com próteses totais fixas suportadas por implantes instalados com cirurgia guiada

Abstract

This study aimed to evaluate the impact of fixed complete denture supported by implants installed in the mandible with guided surgery on the oral health-related quality of life of edentulous patients during a six-month period. For this, a pilot study was previously carried out with a edentulous patient rehabilitated with bimaxillary removable complete dentures, which were later converted into fixed mandibular prostheses supported by four implants installed by the guided surgery technique using the KEA-TECH system. Quality of life assessment was performed using the Oral Health Impact Profile questionnaire (OHIP-EDENT) in the following periods: baseline (prior to implant placement), 3 and 6 months after an implant-supported fixed mandibular prosthesis was installed. The results of this pilot study showed that compared to the baseline (score = 21), there was a significant improvement in all domains of the OHIP-EDENT after 3 (score = 3) or 6 months (score = 1) of the implant- supported fixed mandibular prosthesis placement. The lower the OHIP value obtained, the better the quality of life related to oral health. Thus, despite this pilot study limitations, it was possible to observe that fixed mandibular complete dentures supported by four implants installed by guided surgery improved considerably the oral health-related quality of life of the evaluated patient.
