Immediate function with four zygomatic implants in patients with extreme maxillary atrophy - Case series
Duarte F, Ramos C, Silva JN
Abstract
Purpose: Zygomatic implants have been in use since the 1990’s for the treatment of patients with severely resorbed maxillae. Eliminating grafting combined with immediate function increases patient acceptance. The purpose of this study was to evaluate a protocol for immediate function with fixed prostheses for patients with extreme maxillary atrophy, treated with four zygomatic implants (S.I.N.-Implant System, São Paulo, Brazil).
Case report: This retrospective clinical study included 10 patients with 40 immediately loaded zygomatic implants with fixed provisional acrylic prosthesis attached 5 to 6 hours after surgery. The patients’ follow-up was from 12 to 60 months. Two zygomatic implants failed (implant survival rate 95%). There were no complications such as sinusitis, hygiene maintenance or speech impairment. The results support the hypothesis that immediate function with four zygomatic implants is a viable concept. The clinical success for these patients was enhanced by the shorter time span of the treatment process and the immediate rehabilitation in a comfortable manner as compared to grafting based procedures.
Conclusion: The high survival rate, the increase of patients demand in immediate functional ability and the less morbidity following the surgical procedure renders this immediate function zygomatic procedure a viable treatment option of the resorbed fully edentulous maxillae.
