Modified Precision Lingual Bonding Technique: A Step-wise Approach with Torque Angulation Device-bracket Positioning Device

Abstract

Objectives Contemporary preadjusted edgewise appliance is all about the precision in bracket design, prescription and positioning in addition to the orthodontist’s skill and training. However, achieving it is a bigger challenge as the anatomy of the lingual surface of a tooth is uneven, dissimilar, and moreover the tooth alignment on the lingual surface is variant. Thus, the need for an accurate method of bracket positioning with predetermined torque and angulation incorporated in the brackets according to the patients’ need is of key importance. Materials and Methods A TAD- BPD machine used to enhance the accuracy of bracket positioning and bioplast accurate tray transfer technique was used. Results A step-wise procedures in bracket positioning and fabricating an indirect bonding tray for lingual orthodontics using the torque angulation device-bracket positioning device. Conclusions This technique facilitated unhindered bonding even in severely crowded cases and easy rebonding during mid-treatment stages.
