Summary
This study introduces 3D Apicoectomy Guidance, a novel digital workflow for guided endodontic surgery. This technique offers a precise and reliable method for treating complex apical periodontitis cases, especially those near sensitive anatomical structures.
Area of Science:
- Endodontology
- Digital Dentistry
- Surgical Navigation
Background:
- Conventional endodontic treatments may be insufficient for complex apical periodontitis.
- Digital workflows, including virtual 3D planning, are increasingly utilized in dentistry.
- Endodontic guidance systems offer new possibilities for complex cases.
Observation:
- A novel method, 3D Apicoectomy Guidance, was developed using implantology software, CBCT, and 3D impressions for virtual surgical planning.
- A 3D template guided osteotomy and root resection during ultraconservative endodontic surgery.
- The procedure was applied to a complex case involving proximity to the maxillary sinus.
Findings:
- Virtual planning and a 3D template enabled accurate root apex resection.
- A thin dentin layer was preserved, preventing sinus membrane perforation.
- Post-operative CBCT scans at 1 and 6 months confirmed accurate resection and normal tissue healing.
Implications:
- 3D Apicoectomy Guidance provides a straightforward, reliable, and precise method for endodontic surgery.
- This digital approach allows for expeditious treatment and minimizes tissue removal.
- The technique is particularly beneficial for complex anatomical scenarios, enhancing patient outcomes.
