Computer-Guided Surgery Using Human Allogenic Bone Ring With Simultaneous Implant Placement: A Case Report

Area of Science:

• Oral surgery
• Dental implantology
• Computer-guided surgery

Background:

• Severe horizontal and vertical bone deficiencies pose challenges for dental implant placement.
• The allogenic bone ring technique offers a solution for bone augmentation and simultaneous implant insertion.
• Computer-guided surgery (CGS) can enhance precision in complex dental procedures.

Observation:

• A modified protocol utilized CGS for precise planning and execution of allogenic bone ring grafting and implant placement.
• Digital planning involved merging 3D models with CBCT data to design surgical guides.
• Guides were used to prepare both the implant site and the recipient site for the bone ring.

Findings:

• The computer-guided approach facilitated accurate adaptation of the allogenic bone ring and subsequent implant insertion.
• Post-operative measurements indicated high accuracy in implant placement, with minimal deviations at the entry point, apex, and angle.
• The technique allowed for successful implant restoration after 12 months of healing.

Implications:

• This modified CGS protocol offers a predictable and accurate method for managing severely compromised implant sites.
• It enables a prosthetically driven approach, improving outcomes for bone augmentation and simultaneous implant placement.
• The findings support the integration of CGS in complex grafting procedures for enhanced precision and accuracy.
