Estudos longitudinais dos implantes zigomáticos

Abstract

This paper intends to carry out a descriptive review of scientificliterature about the longitudinal studies of zygomatic implants. Was conducted a methodically search in electronic media, and the articles that reported follow- up of patients who had received implants with remote anchorage for at least three years were evaluated. Are reviewed in this monograph all articles found with a rating higher than three years. Twenty-five articles have been described, where has met a similar survival rate between conventional and zygomatic implants. The maincauses of implant losses were due to lack of osseointegration or recurrent sinusitis that was not resolved, leading to removal of fixation. Term studies show needs of improvement, particularly in the evaluation of sinus tissue, because there was not any research about it, as well as randomized controlled studies of long-term.
