Comparison the accuracy of implant position between static and dynamic computer-assisted implant surgery with two-implant support fixed partial prosthesis

Abstract

Objectives: To compare the accuracy of position and parallelity of two implants, using static and dynamic CAIS systems.

Materials & Methods: 30 patients received two implants randomly allocated to 2 different CAIS systems. Optimal implant position and absolute parallelity was planned based on preoperative CBCT. Implants were placed using surgical guide (static CAIS, n = 15) and real time navigation (dynamic CAIS, n = 15). Implant 3-dimentional deviation and parallelity was calculated after surgery.

Results: The mean deviation at implant platform, apex and angulation in the static and dynamic CAIS group was 1.04 ± 0.67 mm, 1.54 ± 0.79 mm, 4.08 ± 1.69 degree and 1.24 ± 0.39 mm, 1.58 ± 0.56 mm, 3.78 ± 1.84 degree respectively. The parallelity achieved between two placed implants in static and dynamic CAIS groups were 4.32 ± 2.44 degrees and 3.55 ± 2.29 degrees respectively. There were no significant differences in all parameters between two groups.

Conclusions: Static and dynamic CAIS provides similar accuracy of the 3d implant position and parallelity between two implants.
