Implant Placement Under Dynamic Navigation Using Trace Registration: Case Presentations

Area of Science:

• Dentistry
• Surgical Navigation
• Medical Imaging

Background:

• Dynamic navigation implant surgery typically requires fiducial markers and custom stents for Computer-Branched Tomography (CBCT) scans.
• These requirements add complexity, cost, and radiation exposure to the surgical workflow.

Purpose of the Study:

• To introduce and evaluate a novel trace registration technique for dynamic navigation implant surgery.
• To demonstrate the clinical applicability and accuracy of trace registration using intraoral landmarks.

Main Methods:

• A case series was conducted to present the trace registration protocol.
• The method utilizes high-contrast intraoral structures (teeth, implants, abutments) as landmarks, eliminating the need for artificial fiducial markers and stents.
• Postoperative placement accuracy was evaluated.

Main Results:

• The trace registration technique streamlines the surgical workflow, reducing procedural steps and potential errors.
• Elimination of stent fabrication and imaging simplifies presurgical planning.
• The method successfully utilizes natural intraoral landmarks for accurate navigation.

Conclusions:

• Trace registration is a viable alternative for dynamic navigation implant surgery, offering a simplified workflow and reduced radiation risk.
• The technique is dependent on the availability of sufficient high-contrast intraoral structures.
• Further studies can validate its long-term efficacy and broader clinical adoption.
