Abstract

The aim of this study was to evaluate the accuracy of a completely limiting tooth supported stereolithographic surgical guide, with sleeve structure incorporated into the design, for computer-guided dental implant placement in partially edentulous patients using the superimposition protocol using preoperative and postoperative CBCT data.

Materials and Method; 10 implants were placed in 8 consecutive patients using a stereolithographic surgical guide. Postoperative CBCT was taken 6 months after the surgery, 3D accuracy of implants position using a completely limiting tooth supporting surgical guide at the entry point, apex, and angle deviation was measured using an inspection tool software. Chi-square test was used to compare the accuracy of the planned and the placed implant positions. A value <.05 was considered significant.

Results

The mean coronal deviation was.4390°, the sagittal deviation was.2424° and the mesial shift was.1980mm with a standard deviation of.23459° in the coronal,. 26632 in the sagittal and.16315mm in the mesial shift. The statistical analysis demonstrated no significant difference between the implants placed when comparing the bony entrance point and angulations in coronal, mesial and sagittal directions (p < 0.05)

Conclusions

The completely limiting tooth supported surgical guide used has proved high accuracy for implant insertion.
