Abstract
This study aimed to evaluate oral health-related quality of life (OHRQoL) in partially dentate subjects, presenting extreme tooth loss in posterior region with missing post-canines, comparing the use of conventional removable partial dentures (RPDs) and implant-supported RPDs. OHRQoL was measured using the Brazilian version of the Oral Health Impact Profile. Twelve subjects presenting maxillary total and mandibular Kennedy Class I edentulism (mean age 62.6±7.8 years) first received complete maxillary dentures and conventional mandibular free-end RPDs. After two months, the subjects had their OHRQoL assessed. Osseointegrated implants were inserted bilaterally in the mandibular first molar regions, and after four months ball abutments were placed to support the free-end RPD. Two months later, the patients had their OHRQoL reassessed. Wilcoxon signed-rank test was used to evaluate differences in OHRQoL (α=0.05). Results showed improvement in all OHIP-49 domains (p<0.05) after associating implants to the RPD. The mandibular implant-supported free-end RPD significantly improved OHRQoL.
Highlights
Public health programs and development in technology have contributed to a decrease in edentulism worldwide; yet tooth loss is still a reality [1]
Subjects were required to present as inclusion criteria total maxillary and partial mandibular edentulism, presenting only the mandibulary canines and incisors, as well as sufficient bone height and volume in the mandibular molars region
These bone aspects were evaluated by panoramic radiographies and computed tomography
Summary
Public health programs and development in technology have contributed to a decrease in edentulism worldwide; yet tooth loss is still a reality [1] In this context, the number of partially edentulous individuals requiring prosthetic treatment has been increasing [1]. A technical and clinically satisfactory prosthesis is not necessarily a predictor of patient satisfaction, fulfilling the needs and expectations of the patients as regards the prosthesis [8]. In this sense, patient-centered outcome measurements are important to better understand the effect of different treatments on patient’s well-being and quality of life [9]
