Abstract

The aim of this study is to evaluate the impact of anatomical, prosthetic features and implant location on quality of life (QoL) after treatment with locator-retained mandibular overdentures. Thirty patients with locator-retained mandibular overdentures were included in this study. The study examined the following: (1) demographic characteristics, (2) intraoral measurements, (2a) the age of the prosthesis, (2b) the distance between the implants, (2c) the distance between the alveolar crest and the hypothetical line that crosses two implants (2d) the crest section, (2e) tissue quality, (2f) the arc form, (3) measurements of the prosthesis, (3a) freeway space, (3b) the distance between the canines, (3c) the top of the canine/the distance between the distal teeth of the second molar tooth, (3d) the canine/molar angle, and (3e) the arc form saved. After the measurements were made, patients were asked to mark the VAS (100 mm) scale to indicate their satisfaction with their prostheses and to complete the OHIP-14 questionnaire. A multivariate linear regression analysis was performed using OHIP-14 and VAS variables. The multivariate linear regression analysis showed gender and the distance between the alveolar crest and the hypothetical line that crosses two implants (2c) as the most important factor affecting anatomic, prosthetic features and implant location on QoL (p
