Accuracy of 3D Printed Custom-Made Registration Method for Dynamic Navigation Implant Surgery Using Mininavident in the Esthetic Zone: A Clinical Trial

Recruiting now · Not applicable

Conditions studied: Dental Implantation Accuracy

In brief

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.
