Application of a surgical navigation system for implant surgery in a deficient alveolar ridge postexcision of an odontogenic myxoma.
PURPOSE: The study's purpose was to describe the application of a surgical navigation system for the treatment-planning and subsequent precise placement of dental implants in a patient, 2 years postexcision of a mandibular odontogenic myxoma. PATIENTS AND METHODS: A 25-year-old male patient presented for rehabilitation of a deficient edentulous ridge at the right mandible following excision of an odontogenic myxoma. The patient was imaged by dental computed tomography while wearing an individually fitted interfacing acrylic splint. Thereafter, computed tomography data were imported to the Image-Guided Implantology system (IGI; DenX Advanced Dental Systems Ltd, Moshav Ora, Israel), and a precise 3-dimensional implant treatment plan was contemplated considering the compromised anatomy and the anticipated prosthesis. RESULTS: Three dental implants were placed using a surgical navigation approach with precise coordination to the presurgical treatment plan and subsequently were restored with a screw-retained fixed prosthesis. At the 1-year follow-up, the implants were osseointegrated and the fixed prosthesis was fully functional. CONCLUSIONS: Computerized navigation is indicated for dental implant surgery in patients with deficient alveolar ridge where coordination of the positioning of the implants to the final prosthesis is difficult.

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.

Retrospective clinical review of dental implants placed in a university training program.
Many dental schools offer implant clinical training at the pre- and postdoctoral levels, but little has been published on the clinical outcomes of implants placed in those programs. A post-entry chart review was conducted of all Branemark and Taper-Lock implants placed in a university clinic by faculty-student teams. Case information was gathered on data reporting forms and entered into a computer spreadsheet program. Survival rates were calculated as percentages. Cumulative implant survival was 96% for all 303 implants placed. Eight of the 12 implants that failed were placed by 2 operators, only 1 of whom was in the early stages of implant training. Branemark implant survival was 94.9% (n = 198) at 36 months; failures occurred between stage 2 and 3 months (n = 8) in mandibles and after 12 months (n = 2) in maxillae. Taper-Lock implant survival was 98.1% (n = 105) at 24 months; no mandibular failures occurred, but maxillary failures occurred before stage 2 (n = 1) and after 12 months of loading (n = 1). Taper-Lock implants exhibited a slightly higher (3.2%) cumulative survival rate at 24 months compared to Branemark implants. Differences in the numbers of implants placed (105 vs 198) and follow-up times (24 months vs 36 months) may have skewed the comparative results of Taper-Lock and Branemark implants, respectively, in this study. Implant survival for both systems was similar at 24 months of follow-up, and clinician experience did not appear to be an influencing variable on implant survival.

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.

Flapless approach for removal of bone graft fixing screws and placement of dental implants using computerized navigation: a technique and case report.
This article presents a technique for the removal of the screws used to fix a bone graft and for the placement of dental implants in a flapless approach that utilizes the tracking technology of a computerized navigation system. A 24-year-old female patient injured in a terrorist bombing suffered from tooth loss and a bone defect in the maxilla. The area was grafted with bone from the chin in preparation for the placement of dental implants. Four months following the grafting procedure, the fixing screws were removed and the dental implants were placed in a flapless approach by the application of a specialized computerized navigation system. This technique emphasizes the potential of computerized navigation approaches in the facilitation of minimally invasive oral surgery.
