Skeletal Anchorage using Mini-implants in the Maxillary Tuberosity Region

Abstract

Anchorage conservation has always been a challenge in orthodontics especially in cases requiring group movement of teeth. The drawbacks of conventional anchorage conservation methods like headgears and intermaxillary elastics have been overcome with the advent of skeletal anchorage. Mini-implants which have been proved successful in several intraoral locations for anchorage, can also be successfully placed in the maxillary tuberosity region. However, this site is not commonly used due to the fact that the density of bone in this region is comparably low. But with proper case selection and application of sound biomechanical principles, successful treatment results can be achieved with mini-implants placed in this location.The case reports discussed in the article demonstrates the ability of mini-implants when placed in the maxillary tuberosity for en masse distalization of the entire maxillary dentition, its advantages and biomechanics.

Group Distal Movement of Teeth Using Micro-Screw–Implant Anchorage- A Case Report

“…An implant success rate of 90% for group distal movement of teeth was suggested by Hyu-sang park et al, [6]. Reports from Sundaram Venkateswaran et al, [8,9], suggested high success rate of micro-implants and proper biomechanics for enmass retraction using skeletal anchorage in tuberosity and retromolar areas.…”
