Management of anchor loss with the use of infrazygomatic implants – A case series

Abstract

The mesial tipping of the first molar marks the onset of anchorage loss, and changes in the angulation of the first molar are closely related to anchorage loss. Despite the various treatment strategy, different patients show different tendencies towards anchorage loss, which influences the treatment results and must be managed. The quest for search for an ideal intraoral anchorage device has led orthodontists to micro-implants or temporary anchorage devices (TADs), which offer to solve one of the greatest dilemmas of “anchorage control. The use of miniscrews has been increased recently due to their ease of insertion and removal, reasonable cost, biocompatibility and capability to withstand orthodontic forces The introduction of the mini screw and infrazygomatic implant has provided orthodontists with a solution to the significant challenge of "anchorage control." This case series describes the successful management of anchor loss with the infrazygomatic implant(IZC) that occurred during premolar extraction space closure in a Class I and Class II malocclusion patients with severely proclined maxillary incisors.
