Abstract

AIM:

The aim of this study was to evaluate 141 zygomatic implants for the reconstruction of severely aptrophic maxillae.

MATERIALS AND METHODS:

In this retrospective case series study, zygomatic implants were placed under general anesthesia. Inclusion criteria were as follows: ASA I OR asa II, age older than 18 years, in adeaquate bone for restoration with conventional implants, alternative augmentation procedures considered either inappropriate or contraindicated, absence of a medical condition related to implant failure, and providing written consent. Zygomatic implants used in the study of consisted of three brands: Implantswiss, NobelZygoma, Southern Implant System.

RESULTS:

The study included 45 patients in whom 141 zygomatic implants were placed. The mean age of patients was 51.76 (range 23 to 72) years. Three patients were rehabilitated with removal prosthesis, 19 patients with were with prostheses and 23 patients with hybrid prostheses. The overall complication rate was 5.67% (two zygomatic implants developed infection [1.4%], one zygomatic implants developed peri-implantitis [0.7%]. three zygomatic implants developed sinusitis [2.1%] and two zygomatic implants were unsuccessful prosthetic rehabilition [1.4%]. The follow-up period ranged from 6 to 36 months.

CONCLUSION:

Clinical complications of zygomatic implants are acceptable and their survival rates are similar to those of endosteal implants. Zygomatic implants can contribute to prosthetic rehabilitation.
