Andy’s ‘T-pin’Crown and root aligning auxillary

Abstract

Orthodontists strive for accurate bracket positioning as it helps in achieving an ideal occlusion more easily. For accurate bracket positioning in direct bonding, various hand-held dental instruments are used. Instruments such as, the Boone and Dougherty gauges, MBT gauges, A-KAM and various other modifications, are used for accurate positioning of brackets. Sometimes the bracket can easily slip when the instrument is removed. So, position adjustments are difficult with such an instrument. Indirect bonding is an easy solution, but it is time-consuming and there is no precise repositioning of brackets that fall off and it does not provide proper root paralleling. This led us to develop an auxiliary which can be used for crown and root paralleling or aligning, horizontal, vertical and axial positioning of bracket (Pre-Treatment assessment) during direct bonding. This will avoid the step of repositioning of the bracket at mid or end of the treatment.
