Problems solved by technology

[0004] However, compared with traditional implant methods, the use of dental implant guide templates lacks vision and sensory control during the operation.
Surgery according to the guide plate and guiding tools cannot adjust the direction of the drill bit in time, and can only be drilled according to the preoperative design, which has low maneuverability. If the non-flap method is used at the same time, there is a risk of damage to important anatomical structures
Secondly, the unsuitable mouth opening of the patient will affect the operation during the operation, especially in the posterior tooth area, the superposition of the height of the dental implant guide template, the pressure plate, and the drill bit is a test for the patient's mouth opening

Abstract

The invention provides a dental ball drill bit calibration device, which comprises a ball drill fixing device, an optical tracking system and a surgical tool. The ball drill fixing device comprises awork table, a three-layer bearing, a first clamping tool, a universal arm, a second clamping tool, a centripetal universal fisheye bearing and a third clamping tool, the optical tracking system includes an optical tracking device and a tracking rigid body, and the surgical tool comprises a ball drill and a drill bit fixed on the ball drill. The dental ball drill bit calibration device provided bythe invention can accurately obtain the position information of the ball drill bit in real time, and has a good visual field. In addition, the present invention also provides a calibration method based on the dental ball drill bit calibration device.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a calibration device and a calibration method for a dental ball drill bit. Background technique [0002] Dental implants are currently the most common treatment for missing teeth in the oral cavity. Dental implants are implants placed in the alveolar bone in the edentulous area of ​​the oral cavity. After osseointegration, they are used as artificial tooth roots, and then dentures are installed on them to complete the restoration of missing teeth. [0003] In the process of dental implants, it is a crucial step to use a ball drill to accurately drill holes in the alveolar bone to place the implant accurately and safely in the alveolar bone. In order to accurately drill holes on the alveolar bone, the prior art often uses a dental implant guide template to solve the problem. The position of the drill hole and the depth of the drill hole can be accurately positioned using the denta...
