Periotest Evaluation of Stability after Insertion of Temporary Anchorage Device

Abstract

Introduction: Skeletal anchorage devices was developed for absolute anchorage during orthodontic
treatment. Because of immediate loading on orthodontic miniscrews, early stability became a essential
requirement for loading forces on miniscrews.
Objective: The aim of this study was to evaluate the early stability of the miniscrews after two weeks of
insertion and the effect of the length and the side of insertion of the miniscrews on its stability using Periotest
device.
Material and Method: Thirty- three orthodontic patients in a collage clinic were recruited who required
bilateral miniscrews for orthodontic anchorage. Under local anesthesia, each patient received two miniscrews
in the maxillary buccal area (one side 1.6x8mm and the other side 1.6x10mm). after two week early stability
measured using Periotest device.
Results: There was no significant different in stability of miniscrew between right and lift sides and between
short and long miniscrews.
Conclusion: length of miniscrew and side of insertion do not affect the early stability of miniscrew.
