Dental Implant Surgical Guide for Precise Positioning

The patent applies preliminary action by creating a surgical guide based on pre-operative imaging (CBCT scans and intraoral scans) and virtual planning. The guide is fabricated before surgery to transfer the pre-determined implant trajectory and position accurately to the patient's mouth, eliminating the need for free-hand positioning during surgery and ensuring precise placement based on prior inspection of the site.

The patent replaces the mechanical flap method with a digital imaging and virtual planning system. CBCT scans and intraoral scans provide detailed 3D visualization of bone position and anatomy without requiring physical incision or flap elevation. The surgical guide then transfers this digitally determined position to the actual surgery, eliminating the need to cut flaps and thereby reducing infection risk and patient discomfort.

The patent introduces a surgical guide as an intermediary device between the digital plan and the drilling operation. The guide physically constrains the drill bit to follow the pre-planned trajectory, preventing drilling errors such as jumping or walking. This intermediary ensures safe and accurate drilling without requiring the surgeon to maintain perfect free-hand control, thereby improving reliability while keeping the actual drilling equipment simple.

The patent applies preliminary action by performing comprehensive virtual planning and creating a customized surgical guide before the surgery. This pre-operative preparation allows the surgeon to identify and correct potential positioning issues in the digital model, ensuring accurate implant placement during the actual surgery. By doing the planning work beforehand, the procedure can be completed in one visit without needing corrective bone grafting or additional appointments, thereby reducing overall procedure time and patient discomfort.
