Clinical outcome of 302 zygomatic implants in 110 patients with a follow-up between 6 months and 7 years.

Abstract

Zygomatic implant surgery is considered as a safe and successful alternative to the conventional implant surgery with bone grafts for patients with severe atrophic maxilla. The aim of this retrospective clinical case series was to report clinical outcome of zygomatic implants with a follow-up between 6 months and 7 years. A total of 110 patients with 302 zygomatic implants were included in this study. The intra and postoperative complications and survival rate of zygomatic implants were evaluated. The study included 110 consecutively treated patients with an age range of 21 to 76 years (mean 57.35 years, SD 10.42). The overall zygomatic implant survival rate was 98.34%. There were five implant failures in four patients. One intraoperative and 17 postoperative complications developed in 18 patients. There were no dropouts and the median follow-up of the patients was 41.75 months (with a range of 6-89 months). According to the results, in cases of severely atrophic posterior maxilla, zygomatic implant surgery can be considered as an effective and safe alternative to conventional implants and bone grafting procedures.
