Summary
This pilot study shows the EZgoma® "Inverted Support Technique" is accurate for zygomatic implant-guided surgery. The guided surgery protocol is reliable, efficient, and safe for patients needing zygomatic implants.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Surgical Navigation
Background:
- Zygomatic implant insertion is complex.
- Accurate placement is crucial for success.
- Guided surgery offers potential improvements.
Purpose of the Study:
- Assess the accuracy of the EZgoma® "Inverted Support Technique" for zygomatic implant-guided surgery.
- Evaluate factors influencing surgical outcomes.
- Analyze implant survival and success rates.
Main Methods:
- 20 zygomatic implants placed in 5 patients with atrophic maxillae.
- Comparison of post-operative implant position to pre-operative digital plan.
- Analysis of linear and angular deviations using 3D imaging software.
Main Results:
- Mean linear distance deviations for implant platform and apex were 1.59 mm and 1.62 mm.
- Mean angular deviation of the implant axis was 1.74°.
- Minor complications included mucositis, sinus fracture, and one case of failed primary stabilization.
Conclusions:
- Guided zygomatic implant surgery using the EZgoma® technique appears reliable and efficient.
- The protocol is ergonomic and safe.
- Further research is recommended to validate these findings.
