AI Technical Summary

Technical Problem

Traditional dental drills have problems such as easy clogging of debris, low cutting efficiency, and stress concentration leading to tooth damage during dental implant surgery. Existing improved structures are difficult to meet the requirements of efficient drilling and tooth protection at the same time.

Method used

A dental drill for implant surgery is designed, featuring a tapered cutting edge, unevenly distributed end chip removal grooves, and a stress concentration structure, combined with a diamond-like carbon coating. This ensures that the drill bit smoothly enters the small hole and effectively removes waste chips, disperses stress concentration, and improves drilling efficiency.

Benefits of technology

This allows the dental drill to smoothly penetrate small holes, avoids getting stuck, improves drilling efficiency and waste removal, reduces tooth damage, and lowers the workload of dentists.

Abstract

The utility model belongs to the technical field of medical instruments, and particularly relates to a dental drill for implant surgery, which comprises a drill handle and a drill body arranged at one end of the drill handle, the drill body is provided with a plurality of blades axially and spirally distributed, and the blades converge on the end face far away from the drill handle to form an invasion cutting portion with taper. The cutting edges form a chambering part extending spirally on the cambered surface of the drill body, and end chip grooves with the number smaller than that of the cutting edges are formed in the cutting part. The axial end of the drill body is provided with the cutting blade with taper, the inclined groove for cuttings to invade is formed in the hole opening of the pre-formed small hole, so that the dental drill can smoothly drill into the pre-formed small hole, the blade is prevented from being clamped in the small hole, the cutting part is provided with the end chip grooves with the number unequal to that of the blade, and the blade back with the axial compression area unequal to that of the blade is arranged, so that the tooth drill can smoothly drill into the pre-formed small hole. The blades on the invasion cutting part are subjected to different axial pressures, and single blade concentrated stress is formed by using the pressure difference, so that the invasion efficiency is improved.
