Accelerated Orthodontic Canine Retraction Using Minimally Invasive Orthocision

Abstract

Background and objectives:The contemporary demand for an accelerated orthodontic treatment associated with the disadvantage of complicated and difficult surgical procedures and corticotomies. The aim of this study was to evaluate the more conservative orthocision technique as a way for accelerating orthodontic treatment. Methods: Ten patients that matched the inclusion criteria were included in the study, which required orthodontic distalization of canines. The contralateral side of each patient used as a control for the experimental side with vertical incisions and decortication of bone with piezo knife both mesial and distal to the retracted canine after alignment and before starting retraction with power chain on 0.017*0.025 inch stainless steel wire. The pre-and post-treatment photographed cast superimpositions were used to quantify the canine distalization and molar anchorage loss and Muhelmans index was used for evaluating preand post-retraction tooth mobility in this study. Results: Statistical analysis showed a highly significant difference between the control side and orthocision side regarding canine distalization distance and time duration and molar anchorage loss. A non-significant result revealed regarding mobility scoring between control and orthocision sides, also a highly significant difference was present between control side and experimental side regarding transverse changes. Conclusions: Orthocision is an effective and a non-invasive way to accelerate orthodontic treatment.
