Summary
This study presents a novel technique for restoring severely damaged teeth using digital planning and double magnetic extrusion. This method effectively preserves tooth structure and periodontal tissues, offering a promising solution for challenging dental restorations.
Area of Science:
- Dentistry
- Restorative Dentistry
- Periodontology
Background:
- Restoring teeth with tissue loss below the gingival margin presents significant challenges.
- Maintaining ferrule and supracrestal tissue attachment is crucial for successful dental restorations.
Observation:
- A 67-year-old male patient with a fractured maxillary left canine was treated.
- Simultaneous double magnetic extrusion was used to create 3mm ferrules on the canine and adjacent lateral incisor.
- The procedure involved digitally designed planning for precise execution.
Findings:
- The double magnetic extrusion technique successfully preserved ferrule and supracrestal tissue attachment.
- Eighteen months post-treatment, restorative margins were sound, and teeth and periodontal tissues remained healthy.
- Digital planning combined with magnetic extrusion proved effective for restoring severely damaged teeth.
Implications:
- This technique offers a viable option for restoring teeth with insufficient supra-gingival tooth tissue.
- Adjacent root canal treated teeth with significant coronal structure loss are suitable candidates.
- The combination of digital planning and magnetic extrusion shows potential for challenging restorative cases.
