“…In an experiment by Sarment et al using the Simplant system, it was reported that the angle deviation was 4.5±2.0° and the position deviations were 0.9±0.5 mm at the top of the implant body and 1.0±0.6 mm at the bottom of the implant body 11) . In another study by Brief et al using the IGI system, it was reported that angle deviation was 4.21° and position deviations were 0.65 mm at the top of the implant body and 0.68 mm at the bottom of the implant body 12) . Using the IGI system too in their study, Casap et al reported that the position deviation 0.35±0.14 mm 13) .…”

To enable accurate implant placement and precise drilling following preoperative simulation, we developed the BoneNavi system. To realize more precise drilling when the holes are upsized, two methods of surgical guiding were attempted in the present study. One involved using multiple surgical guides with titanium tubes of different diameters, and the other involved using a single surgical guide but employing titanium drill guide tubes with different diameters. Drilling accuracy of the two newly developed methods was examined and compared with the results of drilling into a pig bone using only the initial surgical guide. Deviations of the position and angle with the two novel methods were similar: 0.17 mm and 1° respectively. As for the control group whereby drilling was done using only the initial surgical guide, the deviations were 0.25 mm and 3.50° -which were significantly larger than those achieved with the two novel methods. In light of the results obtained, our newly developed BoneNavi system is especially applicable for severe clinical cases that require precise implant placement.

“…In oral and cranio-maxillofacial surgery, registration is often performed using intraoral fiducial markers mounted on an intraoral dental splint device [16,21]. However, the great distance from the registered region (the oral cavity) prevents the use of such intraoral templates for operations in the lateral skull base area [25].…”

“…The splint can be reversibly fixed to the maxillary dentition, and no invasively applied markers are needed. For intraoral interventions, such as the navigated placement of dental implants, the use of dental splint registration has already proven its applicability [16,17]. However, standard dental registration splints are not suitable for IGS of the lateral skull base as the considerable distance between the registration area (the oral cavity) and surgical area results in a high target registration error [4,5,18].…”

Objective: The widespread use of image guided surgery in the frontolateral skull base region has been limited by the need for a reliable and non-invasive registration procedure that provides sub-millimetric accuracy. We developed and validated preclinically a non-invasive, easy-to-use registration device based on a dental splint with a laterally mounted fiducial carrier. Methods: Repeated accuracy measurements were performed on six titanium target fiducials which were screwed into the lateral skull base region of a cadaver head and could be unequivocally identified both on the CT image and in reality. The system accuracy was evaluated by determining the deviation of the real target position from the position indicated in the CT scan. The accuracy of the dental splint-based registration was compared to that of two standard registration procedures: contour-based laser surface registration and fixed marker registration. Results: The mean accuracy of 0.55 AE 0.28 mm obtained when using the maxillary splint device was similar to that obtained with the ''gold standard'' registration using bone-implanted markers (0.33 AE 0.26 mm), while being clearly superior to that obtained with contour-based laser surface registration (1.91 AE 0.74 mm). Conclusions: Registration using the non-invasively fixed maxillary fiducial platform can provide sub-millimetric accuracy in the lateral skull base region. In vivo validation may prove dental splint-based registration to be an accurate and non-invasive alternative option for image guided surgery of the lateral skull base, and may facilitate the application of navigation systems in this delicate region.

“…This integrates anatomical, biomechanical and esthetic effects. Surgeries with the use of the direct navigation technique facilitate precise implant positioning at the angle of future prosthetic reconstruction, which creates favourable conditions for full accommodation of the reconstruction, and not for the adaptation of the future prosthetic reconstruction to the implant position [15][16][17]. A navigation technique allows the operator to achieve full spatial orientation at every moment of the surgery and does not require surgical templates, which is known as a blind preparation through faucets in stereo-lithographic templates [18].…”

Accuracy of image‐guided implantology

Abstract: Image-guided insertion of dental implants is significantly more accurate than manual insertion. However, the accuracy that can be achieved with manual implantation is sufficient for most clinical situations.
