Cone-wedge anchored surgical templates for stackable metal guide: a novel technique

Area of Science:

• Dental Implantology
• Surgical Navigation
• Biomaterials Engineering

Background:

• Stackable metal surgical guides are crucial for dental implant placement.
• Existing guides face challenges with instability, potentially affecting accuracy.
• A need exists for enhanced anchoring mechanisms to improve guide stability.

Purpose of the Study:

• To present a novel cone-wedge anchoring mechanism for stackable metal surgical guides.
• To evaluate the stability enhancement and accuracy improvement offered by this new technique.
• To address the inherent instability issues in current implant surgical guides.

Main Methods:

• A new cone-wedge anchoring mechanism was developed for stackable metal surgical guides.
• Postoperative implant positions were analyzed using Mimics Medical and Materialise Magics software.
• Key metrics assessed included 3D coronal deviation, 3D apical deviation, and angular deviation.

Main Results:

• The cone-wedge anchor demonstrated improved stability in stackable metal surgical guides.
• High precision in implant placement was observed, with average deviations of 0.97 mm (coronal), 1.56 mm (apical), and 2.95° (angular).
• Postoperative cone-beam computed tomography (CBCT) confirmed the accuracy of the technique.

Conclusions:

• The novel cone-wedge anchoring mechanism effectively enhances the stability of stackable metal surgical guides.
• This technique significantly improves the accuracy of dental implant placement procedures.
• The findings suggest a promising solution for overcoming instability in surgical guide systems.
