A mechanical computerized three-dimensional scanner with a resolution of 1 micron was used to assess loss of enamel caused by orthodontic bonding and debonding. A total of 2646 measurements was performed on six human premolars. The results showed an average loss of enamel of 7.4 microns. The range was between 1 and 52 microns, which may account for discrepancies with earlier studies that measured only a few points per tooth surface.
使用分辨率为1微米的机械计算机化三维扫描仪来评估正畸粘结和脱粘导致的牙釉质损失。对六颗人类前磨牙进行了总共2646次测量。结果显示牙釉质平均损失7.4微米。范围在1至52微米之间，这可能解释了与早期研究结果的差异，早期研究仅在每个牙齿表面测量了几个点。
