Comparison of Accuracy for Three Types of Implant Surgical Guides
Abstract
Statement of Problem. Accurate placement of implants in bone is critical for preservation of anatomical structures, restorability, and survival of the implant. While literature on the success and survival of implants is plenteous, there has been little investigation into the effect of differenttypes of implant surgical guides on the accuracy of implant placement. Purpose. To investigate the effect of conventional, partially guided, and fully guided implant surgical guides on the angulation of placed implants. Material and Methods. An implant was digitally planned, and its 3D placement was utilized to fabricate three groups of surgical guides. The groups were divided based on the amount of guiding provided and were termed one drill protocol (fully-guided), partially-guided and conventional approach. Four periodontists used the guides to place trilobe internal connection implants into 3D printed models. The angulation difference between planned and actual implant position was calculated. A 1-way ANOVA was used to examine the effect of surgical guide type and provider on the accuracy of implant placement.
