PURPOSE: To assess the accuracy of one-piece implant placement using stackable surgical guides by means of a novel stent defined as a number guide screwed onto the fixed base template to improve the intrasurgical registration of the scan bodies.
MATERIALS AND METHODS: A digital workflow was used for one-piece implant planning and placement. Participants were selected based on specific criteria, and stackable guides were used for fully guided implant placement with immediate provisional loading. The accuracy of implant placement was assessed by comparing pre- and post-intervention data registered with the aid of the number guide.
RESULTS: A total of 10 participants were treated with 47 one-piece implants placed in the maxilla and mandible. All implants achieved adequate primary stability, allowing immediate loading. Accuracy was measured by linear and angular deviations, showing greater precision in the mandible. Implant characteristics yielded statistically significant differences in terms of accuracy.
CONCLUSIONS: A fully guided digital workflow ensured precise implant placement and immediate provisional loading. The additional use of the number guide allowed effective accuracy assessments of the system in terms of linear and angular deviations, highlighting its potential to assess postoperative implant placement.
