Factors that contribute to the failure of orthodontic mini-implants: A literature review

Abstract

Introduction: The successful correction of various malocclusions in orthodontics requires absolute anchorage. Hence it is thought that temporary anchorage devices (mini-implants) could provide a good solution for the problems that are encountered in conventional mechanics used for absolute anchorage. The aim of this review is to analyze the available literature on mini-implants in orthodontics so that the reader is familiarized with their ever growing importance and with the factors that account for their failures.

Material and Methods: Various databases were searched to write a review article that could provide information about the usage, classification and the factors that resulted in failures of mini-implant systems.

Results: The factors found in literature include mini-implants related failures, operator related failures and patient related failures.

Conclusions: It should be comprehended that mini-implants ought to be selected and used with immense precaution to decrease rate of failures.
