Three-dimensional measurement of enamel loss caused by bonding and debonding of orthodontic brackets

Am J Orthod Dentofacial Orthop. 1997 Dec;112(6):666-9. doi: 10.1016/s0889-5406(97)70232-4.

Abstract

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.
