The liquid guide groove 301 is vertically arranged along the direction from the drill rod 10 to the twist drill 50, namely the liquid guide groove 301 is a plane, and the inner wall of the implant hole on the planting guide plate is not easy to be scratched in the process of preparing a hole (cutting an alveolar ridge and drilling a certain depth); the twist drill 50 is communicated with the liquid guide groove 301, so that the cooling liquid can be directly conveyed to the drill point position of the twist drill 50 from the liquid guide groove 301 of the guide post 30, and the cooling efficiency of the cooling liquid is improved; in order to further improve the cooling efficiency of the cooling liquid, a plurality of liquid guiding tanks 301 can be provided, namely, the liquid guiding tanks 301 have a plurality of liquid guiding tanks; and are uniformly distributed on the outer wall of the guide post 30.
The depth of the dental pilot drill hole is not defined, so that a stop edge 20 may be provided at the end of the pilot post 30 facing away from the twist drill 50 to prevent the dental pilot drill from continuing to drill down after drilling to a desired depth. In order to allow the stop edge 20 to be snapped into the implant opening or to abut against the implant guide, the maximum width of the stop edge 20 may be greater than the diameter of the guide post 30. In some embodiments, the stop edge 20 is annular, and the diameter of the stop edge 20 is larger than that of the guide post 30, so that the possibility of injury to a patient caused by too deep penetration of the dental guide drill is reduced.
The arrangement of the stop edge 20 is not beneficial to conveying the cooling liquid to the liquid guide groove 301 of the guide post 30, so that the cooling liquid is influenced to be directly conveyed to the drill point position of the twist drill 50, and the cooling efficiency of the cooling liquid is reduced; for this purpose, the stopping edge 20 may be provided with a liquid guiding hole 201, that is, the stopping edge 20 is provided with a liquid guiding hole 201 corresponding to the liquid guiding groove 301, and the liquid guiding hole 201 is disposed in communication with the liquid guiding groove 301. In preparing the hole, the cooling liquid is conveyed from the liquid guiding hole 201 of the stop edge 20 to the liquid guiding groove 301 of the guiding column 30 and then to the drill point position of the twist drill 50. The stop edge 20 of the liquid guide hole 201 corresponding to the liquid guide groove 301 does not affect the cooling efficiency of the cooling liquid, and can ensure the depth of the prepared hole of the dental pilot drill.
The twist drill 50 on the dental pilot drill is used for cutting the alveolar ridge and drilling a certain depth, but only the cutting efficiency of the twist drill 50 is low, so that the requirement on the mouth opening degree of a patient is met, the patient is required to keep a larger mouth opening state for a long time, and the muscular joint pain of the oral cavity of the patient is easy to cause. In order to increase the hole preparation speed, a spiral drill bit 40 is further arranged between the guide post 30 and the twist drill bit 50, and the spiral drill bit 40, the guide post 30 and the twist drill bit 50 are coaxially arranged, so that the hole preparation speed of the dental guide drill can be increased, and the pain of a patient is reduced.
