Modified bracket holder with magnifying lens: A precise bracket positioner

Introduction

A well-finished orthodontic case has the proper alignment of crowns and roots and level marginal ridges. With pre-adjusted brackets (straight-wire appliances), the position of the bracket on the crown determines the tooth’s final tip, torque, height, and rotation. Poorly positioned brackets result in poorly positioned teeth and necessitate many more archwire adjustments. This can lead to an increase in treatment time or a final occlusion that is less than ideal.1, 2, 3, 4, 5

During the bonding procedure of placing the bracket, checking the position with the mouth mirror and then adjusting to the ideal position is time-consuming and the bracket displacement while repositioning might reduce the bond strength.

Therefore, to avoid these drawbacks, a modified bracket holder with magnifying lens will make the procedure simple and accurate. With precise visibility, the magnified image of the tooth surface allows orthodontists to place the bracket accurately according to tooth contour with respect to the mesiodistal and vertical position of the tooth. This magnifying lens which magnifies about 40X is detachable and autoclavable so it can be replaced when damaged.

Welding palatal sheath with band material

Methodology

1. Weld palatal sheath with band material.

2. Check the distance from the tooth surface to the lens for a precise magnifying effect and mark the position on the tweezer.

3. Weld the band material with the sheath to tweezer on the marked point.[Figure 3 A]

Place the lens on welded sheaths of the tweezer. This allows the sliding of lens over the sheath so there will not be a hindrance during the opening and closing of tweezer [Figure 4].
