The tooth has been pressed into its bone socket by the accident. This makes the tooth appear shorter.
Clinical
- Tooth appears shorter
- Wedging in the alveolar bone with metallic percussion sound
Radiological
- Tooth is shifted into the alveolar bone, usually along the axis of the tooth
- Absence of periodontal gap
Therapy
- Reposition
- Splinting for 2-4 weeks
- Systemic administering of Doxycycline
- Root canal treatment as soon as orthograde access can be safely produced (Ledermix for 1 to 2 weeks due to the anti-resorptive effect)
Prognosis
- Unlikely that vitality of the pulp will be maintained in the case of teeth with fully-grown roots (somewhat better prognosis if apex open)
- Resorptions in almost 100% of cases, often infection-related resorptions with inadequate, usually delayed endodontic management!
