Wear of Dental Cutting Tools Coated With Nanocrystalline Diamond Coatings Available to Purchase

Dental cutting tools have traditionally been made using resin-bonded diamonds that have a tendency to breakdown during drilling operations with the consequent loss of diamonds and resin binder into the patient’s mouth. Recent developments in chemical vapor deposition have made it possible to create binderless diamond cutting tools that are useful for machining and drilling enamel, dentine, amalgam, and cast alloys used for crowns and bridges. The paper compares newly developed tools with conventional tools that are used for orthodontic and maxillofacial operations. The reduction in wear using coated diamond tools is significant.
