Description
Technical Field
The utility model relates to a kind implant drill bit technical field specifically indicates a tooth is planted and is bored with location.
Background
Oral diseases become common diseases and frequently encountered diseases which affect the health of residents in China, and bring great troubles to individuals, families and society. According to the incomplete statistics, about 37.0% of adults and 86.1% of old people in China have tooth loss. The whole mouth of the elderly without teeth even reaches about 6.8 percent. With the improvement of the living and cultural level of China, the requirements of people on the quality of life are continuously improved, and the number of patients requiring periodontal treatment, planting treatment, repair treatment and the like is increasing. In the clinical treatment process, the insufficient bone quantity of the alveolar bone caused by inflammation, trauma or tumor operation and the like becomes a problem and a challenge often faced in the clinical practice of oral cavity repair. In this case, one of the prerequisites and basic goals of the oral repair treatment is to restore and reconstruct the lost bone tissue. The best choice for restoring and reconstructing lost bone mass is bone graft powder. The main clinical manifestations of insufficient alveolar bone mass caused by periodontal disease inflammation are periodontal pocket formation, alveolar bone resorption, alveolar bone height reduction, tooth loosening, tooth displacement and chewing weakness, and severe patients can drop their teeth or cause tooth extraction. The repair treatment becomes an important component of the comprehensive treatment of periodontitis, and the repair treatment of periodontitis is based on the fundamental treatment of periodontal disease.
Therefore, aiming at the periodontal problem that the height of alveolar bone is reduced to cause insufficient bone repair, the clinical treatment of the moderate and severe periodontal disease is to perform flap bone grafting to recover the bone mass on the premise of good control of bacterial plaque. Periodontal disease is already a common oral disease, is one of the main causes of adult tooth loss, is also a main oral disease which endangers human teeth and general health, and is very common in flap bone grafting powder in periodontal treatment.
The requirements of bone mass for implantation and repair are very strict, in order to solve the trouble that most patients are difficult to implant and repair due to insufficient bone mass, the technology for restoring and reconstructing bone mass loss by using bone powder periosteum is mature, and the use of bone powder in the implantation is common. However, the binding of bone meal to bone requires certain conditions, such as blood supply. In order to realize osseointegration in the implantation procedure, good blood supply is provided for an implant and implanted bone meal, a ball drill is used for drilling holes on dental lands in a safe area around the implant during the dental implantation operation process after the implantation is completed clinically, surface cortical bone is damaged to obtain the blood supply, and the same is true for bone implantation powder after periodontal flap surgery (drilling holes on dental lands in the safe area in the operation area).
The existing drilling holes are ball drills in clinic, but the ball drills are very easy to slip due to the fact that the ball drills need to rotate at a high speed due to the shape of the ball drills and the drilling holes and the hardness of cortex of human bodies is very high. The proximal and distal slippage may damage the adjacent teeth with good function and shape, and may cause the adjacent teeth to vibrate, lose the teeth, or even loosen. There is of course also a risk of damage to the implant, leading to late peri-implantitis and even implant detachment potential. Vertically upwards relates to the drilling depth, which is less available for cortical blood and therefore should break through cortical bone. Because the hardness of cortical bone is higher, in order to break through cortical bone to obtain good blood supply during clinical operation, pressure is often applied from the bone surface downwards to penetrate cortical bone, but because cancellous bone has lower density and is more elastic than cortical bone, if the pressure is improperly controlled, the possibility of damaging the implant or the tooth root of an adjacent tooth due to too deep drilling is easily caused.
The ball drill is easy to slip, so that the risk is caused, and the three-edged drill for assisting the positioning of the ball drill is also available in the market, but the three-edged drill has the defect that the cortical bone cannot be cut due to small drilling force although the positioning capacity of the three-edged drill is strong.
During the punching process, the doctor needs to continuously change the surgical instruments, and the process is complex; therefore, the currently used instruments cannot be well adapted to the requirements of clinical practical operation. Currently, no effective planting drill bit is available in the market to fill the gap.
SUMMERY OF THE UTILITY MODEL
For solving not enough among the prior art, the utility model provides a tooth is planted and is bored with location, the pilot pin can be used for tooth to plant the location, can be used for drilling again, and the arc cutting edge is great for current ball sword drilling force, the phenomenon of skidding can not appear.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme: the utility model provides a tooth is planted and is bored with location, includes drill bit and drilling rod, and the drill bit rigid coupling is at the drilling rod tip, and the drill bit includes drill bit body, a plurality of edge and the pilot pin of setting at drill bit body surface along the circumferencial direction, and the edge vertically sets up, and the pilot pin sets firmly the one end center of keeping away from the drilling rod at the drill bit body, forms the sweeps ditch between the adjacent edge.
Preferably, one end of the drill bit body, which is far away from the drill rod, is also provided with a chip groove.
Preferably, the chip flutes are circular.
