摘要

Background

Precise implant placement is critical for prosthetic success and long-term clinical outcomes. Computer-assisted design and manufacturing (CAD/CAM) has enabled fabrication of surgical guides that may enhance placement accuracy compared with conventional techniques.

Aim

To evaluate the accuracy of implant placement using 3D-printed CAD/CAM surgical guides versus conventional resin guides.

Materials and Methods

In this prospective randomized study, 36 implants were placed in partially edentulous patients and allocated into two groups: Group A (3D-printed CAD/CAM guides) and Group B (conventional guides). Post-operative CBCT scans obtained at 1 month were analysed for angular, coronal, apical, and depth deviations from the planned implant position. Statistical comparisons were performed using independent t-tests.

Results

All implants achieved successful osseointegration at 1 month (100% survival rate). Guided surgery demonstrated significantly lower deviations compared with conventional guides: angular deviation (2.43° vs. 5.40°, p < 0.001), coronal deviation (1.04 mm vs. 2.59 mm, p < 0.001), apical deviation (1.94 mm vs. 3.37 mm, p < 0.001), and depth deviation (1.95 mm vs. 3.68 mm, p < 0.001).

Conclusion

Within the limitations of this study, 3D-printed CAD/CAM surgical guides provide significantly higher accuracy in implant placement than conventional guides, with clinically relevant reductions in positional deviation.
