Summary
This study presents a new digital method using cone-beam computed tomography (CBCT) and 3D guides for precise repositioning of luxated teeth. This technology improves accuracy and predictability in managing dental trauma, ensuring better patient outcomes.
Area of Science:
- Dentistry
- Digital Imaging
- Oral Surgery
Background:
- Traumatic dental injuries require prompt functional and esthetic rehabilitation.
- Accurate repositioning of luxated teeth is crucial to prevent patient discomfort and ensure successful treatment.
- Traditional methods for managing displaced teeth may lack precision.
Observation:
- A patient with a luxated maxillary central incisor (#8) due to trauma presented with palatal displacement and a fractured labial cortical plate.
- Cone-beam computed tomography (CBCT) provided high-resolution imaging to assess the displacement and bone fracture.
- Medical image processing software was used to segment and virtually reconstruct the alveolar socket and reposition the tooth.
Findings:
- A novel digital workflow utilized CBCT data to create a virtual model for planning tooth repositioning.
- A 3D guiding template was designed and 3D printed based on the virtual plan for precise tooth relocation.
- The 3D guide facilitated accurate repositioning and stabilization of the luxated tooth during splinting.
Implications:
- This CBCT and 3D guide technique offers an objective, precise, and predictable approach to managing luxated teeth.
- Virtual planning and 3D printing enhance the accuracy of tooth repositioning and splint fabrication.
- This digital technology has the potential to improve treatment outcomes for traumatic dental injuries.
