Navigation surgery for dental implants: assessment of accuracy of the image guided implantology system.

PURPOSE: The purpose of this study is to assess the accuracy of the navigation provided by the Image Guided Implantology system (DenX Advanced Dental Systems, Moshav Ora, Israel), which was designed to guide the surgeon in the placement of dental implants. MATERIALS AND METHODS: Seven jaw models incorporating special ceramic spheres were imaged by dental computerized tomography. The coordinates of these reference ceramic markers were calculated by the Image Guided Implantology and compared with their actual position coordinates as identified on the computed tomography image. RESULTS: The overall mean spatial navigation error was 0.35 +/- 0.14 mm. The 1-tailed probability of any single measurement exceeding 0.75 mm was less than 0.003, and that exceeding 1 mm was less than 0.0001. CONCLUSION: The Image Guided Implantology system provides highly accurate navigation with less than 0.73 mm error, which is acceptable in dental implantology. The accurate reporting of the exact position of the drilling bur should minimize the potential risk of damage to critical anatomic structures. The accurate intraoperative navigation allows the surgeon to precisely transfer the presurgical plan to the patient.

Image-guided navigation system for placing dental implants.

Navigation-guided surgery has recently been introduced into various surgical disciplines, including oral and maxillofacial surgery. Since the advent of dental implants, dental computed tomography (CT) scans have been used as a diagnostic tool for preoperative planning, but not as part of the surgical phase. This article explains the principles of computer-assisted surgery and describes the use of a computer-guided navigation system in dental implantology. The system uses preoperative dental CT scans for planning and as an integral part of the surgical procedure. This system allows continuous intraoperative coordination of the implantation phase with the preoperative plan, optimizing the accuracy of implant surgery. Deviations from the planned location of the implants are minimal. Several cases are discussed.

Intraoperative computerized navigation for flapless implant surgery and immediate loading in the edentulous mandible.

Computerized navigation surgery has evolved to facilitate minimally invasive procedures, the gold standard of surgery today. While flapless implant surgery may be clinically beneficial, it has generally been perceived as a blind procedure limited to straightforward cases that do not pose a risk of cortical plate perforation. The objective of this report is to describe a protocol for flapless implant placement in a completely edentulous mandible using computerized navigation surgery. The Image Guided Implantology system (IGI, DenX Advanced Dental Systems) is described. The IGI system provides real-time imaging of the dental drill and transforms flapless implant surgery into a fully monitored procedure. The highly accurate intraoperative navigation enables precise transfer of the detailed presurgical implant plan to the patient. This is particularly valuable in edentulous jaws lacking any indication of the dental arch. The accurate positioning of the implants, based on the presurgical digital plan, allows fabrication of a provisional fixed prosthesis before the implant surgery for immediate postoperative loading. This innovative protocol can enhance prosthodontic-driven placement of implants in a fully monitored flapless surgery.
