This clinical trial evaluates the accuracy of a 3D printed custom-made registration method for dynamic navigation implant surgery using the Mininavident system in the esthetic zone of the anterior maxilla. Ten patients with a single missing anterior tooth will undergo CBCT-based planning, intraoral scanning, and guided implant placement using 3D printed registration markers. Postoperative CBCT analysis will measure deviations between planned and placed implants in terms of angular, coronal, and apical positions. The study aims to determine whether 3D printed markers provide clinically acceptable accuracy (<2 mm, <5°) and to assess their feasibility as a reproducible alternative to standard registration methods.

Accurate implant positioning is essential for esthetic and functional success, particularly in the anterior maxilla. Dynamic navigation systems (DNS) provide real-time guidance but depend on reliable registration between patient anatomy and virtual planning. Errors may occur with conventional fiducial markers, highlighting the need for more precise methods.

This clinical trial investigates the use of 3D printed custom registration markers with the Mininavident DNS for implant placement in the esthetic zone. Ten patients with a single missing anterior tooth will undergo CBCT-based planning and guided implant placement using the custom markers. Postoperative CBCT scans will be compared with preoperative plans to measure positional and angular deviations.

The primary outcome is the accuracy of implant placement, with deviations expected to remain within clinically acceptable limits (<2 mm, <5°). Secondary outcomes include assessing the feasibility and reproducibility of incorporating 3D printed registration into DNS workflows. Results may validate this approach as a cost-effective, patient-specific solution to enhance precision and predictability in implant dentistry.
