Efficacy of Selective Grinding Guided by an Occlusal ...
Selective grinding of the tooth surfaces to produce occlusal adjustment has been described as a valid adjunct to orthodontic treatment for improving the overall contact pattern of the teeth [19, 20]. However, the procedure must be well planned, based on precise diagnosis, and use a controlled and accurate method.

Grinding Basics | NORITAKE CO.,LIMITED
The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.
