A Novel Digital Process For The Treatment Of Alveolar Fracture

A digitally designed customized splint successfully treated a severe alveolar bone fracture patient. This splint which is based on a digital process, combines rigidity, easy molding, convenient cleaning, and simple removal, achieving excellent therapeutic outcomes. A 43-year-old female presented with traumatic avulsion of upper anterior teeth and alveolar fracture, seeking treatment 20 days post-cerebral hemorrhage. Challenges included extensive bone fracture, delayed intervention, pre-existing periodontitis, and compromised bonding due to resin veneers. Treatment: 1. Reduction: Repositioned teeth and alveolar bone to restore occlusion; extracted lower anterior teeth; stabilized mobile teeth. 2. Digital workflow: - Scanned upper dentition; designed a 3D-printed lingual splint avoiding occlusion and preserving root canal access. - Bonded the splint via etching, drying, and resin application. 3. Follow-up: - 4-week fixation; initiated root canal therapy (teeth 11, 12, 21, 22) at 1 week. - Removed splint post-treatment; fabricated lower anterior teeth. Outcome: Successful stabilization despite complex comorbidities. A novel digitally designed personalized splint provided optimal rigid fixation for a complex alveolar fracture case. The 3D-printed lingual archwire ensured precise reduction and stability,demonstrating superior clinical outcomes. This approach highlights the effectiveness of digital solutions in managing traumatic dental injuries with predictable results. This digital process provides semi-elastic-level fixation through scan-to-splint automation, offering precise stabilization with cost-effective materials for widespread clinical use.
