Abstract
Background: Although several different design methods have been proposed, limited research is available regarding how design features impact accuracy and performance. The purpose of this study was to compare the accuracy of implant site location between two different drilling systems for static computer-assisted implant surgery (sCAIS) in vitro study, each featuring a unique drill stabilization configuration.
Materials and methods: Sixty models were fabricated simulating a patient with maxillary partial tooth missing. Each model included two single-tooth gap (STG) situations; two extraction socket sites; and a distal extension situation. Experimental models were categorized into two distinct groups, group A: a sleeve-in-sleeve system with a metal sleeve embedded in the surgical guide; group B: an integrated sleeve-on-drill system without a metal sleeve. The deviations in shoulder, tip, depth, and angular were measured. Date were analyzed using the Scheirer-Ray-Hare test (P ≤ 0.05).
Results: The deviation of shoulder, tip and angular in group B were significantly lower than group A. When using an integrated sleeve-on-drill system, the remaining deviation values in extraction sockets were significantly higher than those in the STG situation and the distal extension situation, with the exception of depth deviation. However, there is no significant difference between STG situation and distal extension situation.
Conclusion: In comparison to the sleeve-in-sleeve system with a metal sleeve in the surgical guide, the accuracy of an integrated sleeve-on-drill system without a metal sleeve was higher. The accuracy of implantation in extracted sockets was significantly lower than that in healing sites.
