Summary
This study presents a guided protocol for zygomatic implant surgery. Digital planning and surgical guides ensure accurate implant placement and prosthesis repositioning with minimal deviation.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Digital Dentistry
Background:
- Zygomatic implants offer a solution for severe maxillary atrophy.
- Guided surgery protocols enhance precision in complex implant placements.
Purpose of the Study:
- To describe an in-house protocol for fully guided zygomatic implant surgery.
- To evaluate the accuracy of guided surgery and prosthesis repositioning.
Main Methods:
- Digital planning and custom surgical guide creation for four zygomatic implants.
- CBCT analysis to compare planned vs. post-surgical implant positions.
- Radiologic and prosthetic evaluations of deviations.
Main Results:
- Successful osseointegration of all zygomatic implants.
- Mean angular implant deviation of 0.52° and depth deviation of 0.47 mm.
- Mean prosthetic deviations within 0.7 mm in all planes.
Conclusions:
- Meticulous digital planning is crucial for safe and accurate guided zygomatic implant surgery.
- The described protocol demonstrates high precision in implant placement and prosthesis repositioning.
