Determination of Anchor Loss in Patients Undergoing Micro-Osteoperforation and Patients Not Undergoing Micro-Osteoperforation after Enmasse Retraction

Shaeeb Rashid, M B Halkati, Amir Shaikh

Abstract: Introduction: Attempts to accelerate the rate of tooth movement are being made to eliminate risks associated with longer treatment duration. Micro-osteoperforations and piezocision, are said to be least discomforting among all the surgical procedures and can accelerate the tooth movement signicantly resulting in shorter orthodontic treatment. Micro implants routinely used in orthodontics these days can be used for osteoperforations procedure. Hence this study was carried out with and without micro- osteoperforations in experimental and control patients respectively, using mini implants and assessing the amount of anchor loss after enmasse retraction of anteriors. Aims and objectives: The aim of the study is to determine the amount of anchor loss between the patients undergoing micro-osteoperforations and patients not undergoing micro-osteoperforations after the enmasse retraction of anteriors. Materials and Methods: 20 patients in the Department of Orthodontics, Al-Ameen Dental College, Vijayapur were included in the study and retraction was started using sliding mechanics. They were randomly divided into two groups, experimental and control. Micro-osteoperforations were done in the experimental group and 150 grams force was applied immediately using active tie-backs on both sides and enmasse retraction was done. Pre-retraction cephalograms and post retraction cephalograms of the patients undergoing micro-osteoperforations and patients not undergoing micro-osteoperforations were obtained and tracings were done. Vertical line was dropped from Ptm. and distance from distal of upper first molar was calculated. Difference in values of pre and post retraction cephalograms was the amount of anchor loss. Pre and post retraction values were compared by paired t test. The difference was not statistically significant. Results: Results showed that there was no statistical significance in the amount of anchor loss in the experimental group when compared with control group. Conclusion: when compared the amount of anchor loss between experimental and control group, there was no statistical significant difference in the amount of anchor loss.
