Abstract

Purpose: The purpose of this chapter is to review the biomechanical studies, finite element analysis and clinical reports on the prosthetic and surgical principles for the survival of implants when reconstructing the edentulous maxillae using the zygoma implant.

Method: Comprehensive search of studies published from 1983 to December 2015 listed in the PubMed/MEDLINE databases was performed. Relevant studies were selected according to predetermined inclusion and exclusion criteria.

Results: The initial database search yielded 653 titles. After filtering, 192 abstracts were selected, with resultant 33 full-text articles considered relevant and included. Consensus among authors was identified in regard to the number and the distribution of implants; limiting or eliminating distal cantilevers; and importance for the presence of crestal bone at the platform of the zygoma implant which reduces the magnitude of occlusal load on the implant–bone as well as the implant–abutment interface.

Conclusion: The result of this review suggests that placement of the two zygoma implants (ad modum Branemark) in conjunction with 2–4 premaxillary implants, rigidly connected and stabilized with a fixed prosthesis, allows for the favourable force distribution during function. In cases where complete lack of maxillary alveolus is identified, the placement of four zygoma implants, rigidly connected with a fixed prosthesis, also has a predictable outcome.
