Simplified system and procedure for computer-guided dental implant surgery

A simplified computer-guided drilling system for performing dental implant surgery, the system used with a computer made guide element (3b) having an opening (3c) therein, wherein said opening defines a drilling position and a drilling direction, the system comprising:

• a guided perforation drilling means (1), which comprises a drilling body with a pointed end (1b) attached to a smooth-walled cylindrical body (1a);
• and
• one or more expansion means (2) each comprising a guide body with a pointed end (2a) that maintains the drilling position, and a second guide body with a cylindrical-conical shape (2b) and having a diameter that increases as it moves away from the pointed end, to allow the insertion of an implant (3g) whose shape corresponds to a last expansion means but with a larger diameter than the last expansion means;
• wherein the smooth-walled cylindrical body (1a) precisely fits the opening (3c) in the guide element.
