Abstract
The use of virtual reality simulation (VRS) developed a new era in dentistry, where a pre-operative virtual planning in conjunction with a surgical guide could help the surgeon with a prosthetically-driven correct implant placement, especially in difficult clinical cases.
Materials & methods: regarding this study, 14 patients were recruited with bounded partially edentulous spans in the maxilla. The patients were randomly assorted into 2 groups. The first group (control) is the static guide group (SG), while the second group (test group) is the dynamic navigation group (DN). After implant installation, a postoperative CBCT was obtained & the obtained image was superimposed over the original implant plan to determine the linear and angular deviation between the proposed plan and actual implant position.


Results: Regarding the linear deviation between the planned and actual positions in both groups was measured at both the coronal apical areas. The independent sample t test showed a statistically insignificant difference between the two groups. On the other hand, regarding the angular deviation; The independent sample t test showed a statistically significant difference between the two groups.

Conclusion: The Image Guided Implantology system provides highly accurate navigation with less than expected error acceptable in dental implantology. The accurate reporting of the exact position of the osteotomy drills should minimize the potential risk of damage to any critical anatomic structures. Furthermore, the accurate intraoperative navigation allows the surgeon to precisely transfer the presurgical plan to the patient in an accurate prosthetically-driven manner.
