AI Technical Summary
In dental implant surgery, especially when operating in the molar region near the pharynx, fixed-length dental burs are insufficient to provide enough operating space, which limits the accuracy and efficiency of the surgery. In addition, the use of auxiliary tools increases the need for patients to open their mouths, affecting the accuracy of implant placement angle and site.
A dental bur was designed, including a sleeve and a retractable cutting rod. The retraction and extension of the cutting rod are achieved through the linkage and anti-rotation limit components between the sleeve and the cutting rod. In conjunction with the drive system of the implant handpiece, the requirement for operating space is reduced. The extension and extension of the cutting rod are controlled by fluid pressure to ensure the angular and positional accuracy of the cutting part.
Precise preparation of implantation cavities was achieved in confined spaces, reducing reliance on auxiliary tools, improving the safety and precision of the surgery, ensuring the ideal implantation angle and site, and reducing the risk of damage to healthy tissues.
