Comparative Evaluation Of Rate Of Intrusion, Retraction And Amount Of Periapical Root Resorption With Jayades Intrusion Arch And Modified Three Piece Intrusion Arch Using Cone Beam Computed Tomography.

INTRODUCTION

Deep bite, a common orthodontic malocclusion, necessitates timely intervention to prevent potential side effects. If left untreated, deep bite can lead to increased tooth wear, dental injuries, and temporomandibular joint disorders. Various treatment modalities, such as anterior teeth intrusion and posterior teeth extrusion, are employed to correct deep bite. However, selecting the optimal approach requires careful consideration of patient-specific factors and treatment objectives. While anterior teeth intrusion is effective for mild to moderate cases, posterior teeth extrusion may be preferred in severe deep bite scenarios. There are various treatment modalities for deep bite correction such as intrusion arches and mini screw implants.

AIM

“Comparative evaluation of rate of intrusion, retraction and amount of periapical root resorption with jayade’s intrusion arch and modified three piece intrusion arch using cone beam computed tomography.”

MATERIAL AND METHODS

This prospective two arm parallel interventional study involving 20 patients selected from Department of Orthodontics and Dentofacial Orthopaedics out patient department. They will be split into 2 groups. The MBT bracket system with triple tubes on maxillary teeth and a slot dimension of.022" x.028" will be used to begin all cases. After initial alignment and levelling and extraction as per the case then intrusion arch is given. Jayade’s intrusion arch will be given in group A, while Modified Three Piece intrusion arch will be given in group B. The rate of intrusion, retraction and amount of root resorption will be measured before initiation of intrusive and retractive forces and at two, four, six months after application of intrusive and retractive forces

RESULTS AND CONCLUSION

This study will determine the efficacy of simultaneous intrusion and retraction of Jayade’s intrusion arch and Modified Three Piece Intrusion arch interrelated with amount of root of resorption, thus weighing the better treatment modality for rectification of deep bite.
