Technical Field

The invention relates to the field of dental drills, in particular to a dental implant drill bit.

Background

In a dental implant surgery, a dental implant drill is used to prepare an implant hole on an alveolar bone of a patient. The existing implant hole preparation processes have two types, one is multi-time drilling and forming, and the other is one-time drilling and forming. For one-step drilling forming, because the cutting amount of the drill bit is large, cooling liquid sprayed to the drill bit by the existing dental handpiece is difficult to deeply implant into the hole, the cutting edge of the drill bit cuts alveolar bone in the implant hole, and the cooling liquid cannot timely cool the cutting edge, so that the cutting edge seriously generates heat in the working process, and the cutting edge is easily damaged.
