内容記述タイプ Abstract
内容記述 The purpose of this study is to investigate effective procedures for debonding after removal of orthodontic brackets. After ordinary acid bath, thirty extracted mandibular incisors were bonded with metal brackets using either 4-META/MMA-TBB resin or Bis-GMA resin. After 48 hours, the brackets were removed with a Debonding Instrument^[○!R] (Unitek). The resin remaining on the tooth surface was removed with the following instruments: ① removing pliers ② hand scaler ③ ultrasonic scaler ④ No.8 steel round bur. Evaluation was based on observations made of the tooth surface with a scanning electron microscope (SEM), and on the feel of each instrument during use. The results are the following: (1) When the removing pliers were used, the enamel surface was observed to have wide abrasive striations made by the edge of pliers. Though the instrument enabled speedy removal of residual resin, it gave considerable impact to the experimental tooth. (2) When the hand scaler was employed, the enamel surface was found to have slender scratches along the working direction. As the operation required considerable force, it placed a heavy load not only on the operator but also on the tooth. (3) When the ultrasonic scaler was applied with strong force, the tooth surface was seen to have a concave wound in the shape of a hemispherical depression. The operation was inefficient as it required a long time. (4) In case of the No.8 steel round bur used at low speed, comparatively shallow scratches were observed widely covering the entire surface where the residual resin had been removed. As this method did not require much force, the operation could be performed efficiently. From the above results, it was felt desirable for the operator to have a good understanding of the characteristics of each instrument, to select it as the occasion calls, and to use it properly. Also, the use of a No.8 steel round bur without excessive pressure to finish resin removal, after initially removing most of the resin with the removing pliers, is especially believed to be clinically effective as a debonding procedure.
