Extrusion and lateral luxation

¨ Extrusion luxation = a rupture of the periodontal ligament and the pulp

¨ Lateral luxation = a rupture of the periodontal ligament and the pulp as well as an injury to the labial and / or palatal alveolar bone plate

Treatment:

1. Atraumatic repositioning and fixation

2. Local anaesthesia is required if there is an alveolar plate injury

3. Non– rigid functional splint for 2—3 weeks

4. Antibiotics e.g. amoxicillin 250mg TDS 5/7

5. Chlorhexidine 0.2% mouthwash twice daily while splint is in position

6. Soft diet 2 –3 weeks

7. Radiographic examination after 2 –3 weeks prior to splint removal

8. At no sign of marginal breakdown the splint can be removed

Prognosis:

¨ Considerable risk of pulp necrosis, especially in teeth with mature root formation.
