| 摘要 |
The invention relates to a coated tool bit for a dental drilling/cutting system. The tool bit is used to prepare an osteotomy in the jawbone of a patient. The tool bit is coated with a hard carbon coating/film. The coating can comprise diamond-like carbon (DLC), amorphous diamond, crystalline diamond, or a combination thereof. The tool bit includes drilling bits, threadformers, counterbores, and cutting tips of osteotomes. Some of the advantages of the coated tool bit are reduced friction, enhanced cutting efficiency, improved heat dissipation, increased resistance to wear and corrosion, and reduced adhesion to bone, tissue and other debris.
