Abstract

BackgroundThe aim of this study was to present a temporary anchorage device with intraosseous screw for unilateral molar distalization to make a space for the impacted premolar and to found well balanced occlusion in a case.Case presentationA 13-year-old male who have an impacted premolar is presented with skeletal Class I and dental Class 2 relationship. The screw was placed and immediately loaded to distalize the left upper first and second molar. The average distalization time to achieve an overcorrected Class I molar relationship was 3.6 months. There was no change in overjet, overbite, or mandibular plane angle measurements. Mild protrusion (0.5 mm) of the upper left central incisor was also recorded.ConclusionImmediately loaded intraosseous screw-supported anchorage unit was successful in achieving sufficient unilateral molar distalization without anchorage loss. This treatment procedure was an alternative treatment to the extraction therapy.

Immediately loaded intraosseous screw-supported anchorage unit was successful in achieving sufficient unilateral molar distalization without anchorage loss
The researchers have used intaroral distalization mechanics alternatively to the extraction treatment but anchorage loss has shown by the use of a lot of appliances with the significant maxillary incisor proclination and increased in overjet at the end of the distalization. [5,10,11]

Summary

Introduction

The aim of this study was to present a temporary anchorage device with intraosseous screw for unilateral molar distalization to make a space for the impacted premolar and to found well balanced occlusion in a case.Case presentation: A 13-year-old male who have an impacted premolar is presented with skeletal Class I and dental Class 2 relationship. The aim of this study was to present a temporary anchorage device with intraosseous screw for unilateral molar distalization to make a space for the impacted premolar and to found well balanced occlusion in a case. In the treatment of Angle Class II malocclusions, with well-aligned lower teeth and a mandible in sagitally normal position, upper anterior crowding and excessive overjet can be treated with either distalization or extraction of upper posterior teeth. A number of treatment protocols that minimize the need for patient compliance have been suggested previously [4-12]. These techniques effectively distalize the maxillary molars, in most of these studies anchorage loss is unavoidable characterized by maxillary incisor protrusion, an increase in overjet, and decrease in overbite [6,7,11]
