3D-printed custom registration for dynamic navigation implant placement in the upper front teeth
Accuracy of 3D Printed Custom-Made Registration Method for Dynamic Navigation Implant Surgery Using Mininavident in the Esthetic Zone: A Clinical Trial
This tests whether a 3D-printed custom registration marker helps the Mininavident navigation system place dental implants more accurately for patients missing a single front upper tooth.

What this trial studies
Ten patients with a single missing anterior maxillary tooth will receive CBCT-based implant planning and intraoral scanning to create individualized plans. Custom 3D-printed registration markers will be used with the Mininavident dynamic navigation system to guide implant placement. Postoperative CBCT scans will be compared with preoperative plans to measure angular, coronal, and apical deviations. The trial will determine if this registration method yields clinically acceptable accuracy (<2 mm, <5°) and whether it is feasible and reproducible in routine workflows.
Who should consider this trial
Good fit: Adults with a single missing tooth in the anterior maxilla who have adequate bone (≥12 mm height and ≥5.5 mm width), D3 bone density, Angle's Class I occlusion, and no systemic contraindications to implant surgery.
Not a fit: Patients who are heavy smokers, have uncontrolled diabetes, prior head/neck radiation, parafunctional habits like bruxism, or Class III malocclusion are excluded and unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, this could allow more precise and predictable implant placement in the esthetic zone, improving cosmetic results and reducing the need for corrective procedures.
How similar studies have performed: Dynamic navigation systems and 3D-printed surgical guides have previously improved implant placement accuracy, but the use of custom 3D-printed registration markers with Mininavident is relatively new with limited published validation.
