Problems solved by technology

But the drilling depth of the guide plate is not accurate enough
At the same time, conventional stainless steel drills do not give patients a good experience, and safety and health, good heat dissipation, precise positioning and long tool life are always the main points of concern for various drills.

Abstract

The invention relates to a dental instrument, in particular to a ceramic drill bit for drilling of a dental planting guide plate. A ceramic nail planting expanding drill comprises a drill bit body anda drill stock; and the drill stock is designed as an RA handle matched with an oral contra-angle handpiece. A scale groove is formed from the middle part to the tail part of the drill bit body. According to the invention, safety, health and accuracy of nail planting can be improved; heat dissipation is good; and chip accommodation capacity is high.

Description

technical field [0001] The invention relates to a dental instrument, in particular to a ceramic drill used for drilling a dental implant guide plate. Background technique [0002] Dental implant is a new type of oral restoration technology that has been clinically developed in recent years. In traditional implant surgery, the drilling is done by the doctor's manual operation based on experience. The doctor's visual inspection and hand control ability determine the accuracy of drilling. position, angle and depth. In minimally invasive implant surgery, since the alveolar bone is covered by gingival tissue, the anatomical features of the alveolar bone in the implant area cannot be directly observed with the naked eye. Therefore, the accuracy of implant placement depends entirely on the doctor's clinical experience and operating level. [0003] People have developed the dental implantation guide plate for this reason, and the doctor only needs to implement drilling along the gu...
