Mumcu, Emre / Dayan, Suleyman Cagatay / Genceli, Emrah / Geckili, OnurPage 388 - 396Objective: The purpose of the present study was to compare and assess maxillary edentulous patients treated with four-implant-retained overdentures and with implant-supported fixed prostheses using the All-on-4 concept in terms of patient satisfaction, oral health-related quality of life, and marginal bone loss.Method and materials: Thirty-three patients treated with either maxillary four-implant-retained overdentures (n = 15) or with maxillary implant-supported fixed prosthesis using the All-on-4 concept (n = 18) were compared in terms of patient satisfaction, quality of life, and marginal bone loss. Independent sample t test was used to compare the two groups in terms of satisfaction, OHIP-14 scores, and marginal bone loss. The paired sample t test was used to compare bone loss at different time intervals. The comparison of marginal bone loss with regard to implant location was accomplished with the one-way ANOVA test.
