This article reports clinical procedures used to remove residual bonded resin and enamel stains following bracket "debonding" at the conclusion of orthodontic treatment. A water-cooled fine-tapered diamond bur was used for resin removal, followed by enamel surface finishing using a commercially available microabrasion paste. It was noted that residual tooth coloration remained yellowish because of enamel translucency; the yellow dentin shade showed through. Additional tooth shade lightening was achieved using carbamide peroxide dental bleaching solution in custom-formed trays. This report describes a safe and effective technique that optimizes tooth appearance at the conclusion of orthodontic therapy. Mechanical resin removal, enamel microabrasion, and tooth bleaching are employed.
A combination of treatment methods are sometimes required for the best esthetic result. After orthodontic treatment, mechanical resin removal followed successively by enamel microabrasion and tooth bleaching can yield ideal long-lasting improvement.
本文报道了正畸治疗结束后去除托槽“去粘结”后残留粘结树脂和牙釉质污渍的临床操作。使用水冷细锥形金刚砂车针去除树脂,随后使用市售微研磨膏对牙釉质表面进行抛光。注意到由于牙釉质半透明,残留牙齿着色仍呈淡黄色;黄色牙本质颜色透了出来。使用定制托盘内的过氧化脲牙齿漂白溶液进一步减轻了牙齿颜色。本报告描述了一种在正畸治疗结束时优化牙齿外观的安全有效技术。采用了机械去除树脂、牙釉质微研磨和牙齿漂白方法。
有时需要联合多种治疗方法以获得最佳美学效果。正畸治疗后,依次进行机械去除树脂、牙釉质微研磨和牙齿漂白可产生理想的持久改善效果。
