Resum

Objective: To evaluate the accuracy of immediate implant placement in fresh extraction sockets in the maxillary aesthetic zone using a dynamic computer-assisted implant surgery system (dCAIS), with the evaluation of possible deviations versus freehand placement. Methods: A total of 18 implants were placed by an experienced surgeon in fresh extraction sockets of anterior teeth in 6 maxillary models. Nine implants were placed using the dCAIS system and 9 implants were placed using the conventional freehand technique. The following outcome parameters were measured and compared: positional deviation at entry, apex point and angular deviations between planned and placed implant position. Surgery time was measured for each procedure. Descriptive and statistical analyses were performed on all outcome parameters. Results: Global entry deviations were not significantly different between the two techniques (p = 0.078). dCAIS resulted in significantly more accurate implant placement in terms of global apex deviation with values of 1.28±0.36 mm and angular deviations with values of 1.29±0.64°, compared to 2.06±0.60 mm and 5.05±2.54° with freehand placement (p < 0.001). The dental implant placement time was approximately three times longer when using dCAIS (10.99 ± 3.43 min) versus freehand (3.25± 0.63 min) (p < 0.001). Conclusions: dCAIS achieved more precise immediate implant placement in terms of apex deviation and angulation than freehand placement, but increased the surgery time. Clinical significance: dCAIS provides greater accuracy in the placement of immediate implants in the maxillary aesthetic zone following prosthetic-driven digital planning compared to freehand surgery.
