Anchorage in orthodontics is of prime importance for effective results. With the introduction of temporary
anchorage devices (TADs) as skeletal anchorage method its use has been popularised. Although all
anchorage systems have their own merits but they are often associated with certain demerits too. Since, literature is ooded with
articles documenting the success rate but, as there are always two facets to everything, an insight to the failures of TADs should
also be unravelled. So, review was done with the objective to evaluate the factors responsible for the failure of mini
implants.Strategic and through search of the literature in four major databases was undertaken for data extraction and
conclusion was drawn that mini implant failure is a multifactorial problem which includes mini implant related factors, clinician
related factors and patient related factors.
