Dental implant drill bit

Abstract

The invention relates to the technical field of dental instruments, in particular to a drill bit for dental implantation. The specific technical solution is: a drill bit for dental implantation, including a drill bit and a drill rod fixed by a base plate, a bearing is set on the drill rod, an abutment is fixed on the outer ring of the bearing, and a water storage chamber is arranged at the axis of the drill bit. The water storage cavity is provided with a water outlet channel communicating with the water storage cavity, and a chip suction cavity is provided around the water storage cavity in the drill bit, and several chip suction holes communicated with the chip suction cavity are arranged on the side wall of the drill bit; There are several annular chip suction holes communicated with the chip suction chamber and several water inlet channels communicated with the water storage chamber, and the abutment is provided with an annular chip suction groove communicated with the annular chip suction holes and an annular water inlet channel communicated with the water inlet channel , the annular chip suction groove and the annular water inlet groove are respectively provided with an air port and a water inlet, and the air port and the water inlet are respectively connected with an air pump and a water pump through pipelines. The drill bit provided by the invention can simultaneously cool the drill bit and remove chips during the working process.

Description

technical field [0001] The invention relates to the technical field of dental instruments, in particular to a drill bit for dental implantation. Background technique [0002] The existing drill bits for dental implants are made of stainless steel or hard alloy materials. They are connected to the mobile phone for implantation through the handle. The high-speed rotation of the mobile phone drives the drill bit to rotate. The working part directly acts on the alveolar bone of the human body. Drill holes on the alveolar bone in the same way. After the drilling is completed, the mobile phone is reversed and withdrawn from the drill bit. The size of the drill bit matches the diameter of the dental implant, and the operator selects the matching drill bit according to the size of the implant to be used. [0003] Drills for planting are divided into positioning drills, pilot drills, pilot drills, reaming drills and forming drills. The material is stainless steel, and the most frequ...

Problems solved by technology

After the service life is reached, the size and strength of the cutting edge will decrease, and the cutting ability will be limited

Therefore, it is necessary to cool the drill bit to improve the life of the drill bit. During the drilling process, debris will be generated, which will increase the difficulty of drilling and may cause jamming. Therefore, it is necessary to remove debris while cooling.

[0005] Moreover, when the drill bit is drilling the alveolar bone of the posterior molar, due to the size of the space in the oral cavity, the hole drilled on the alveolar bone may be inclined, and may even be caused by the drill rod being too long. Reasons why a hole in the alveolar bone cannot be successfully drilled
