Definitions:
- Autotransplantation: Surgical movement of a tooth from one location to another
- Trans alveolar transplantation (TAT): surgical movement of tooth to its correct position (surgical uprighting)
Impacted premolar
Technique
- Requires careful surgical technique, no contact root
- Use of CBCT to create 3D replica tooth, to idealise recipient site
Root length
- Early in formation = easier surgical access
Survival
- 100% Plakwicz 2014
Success of autotransplantation
- Absence of progressive root resorption
- Normal periodontal tissues
- Crown:root ratio less than 1 Kugelberg 1994
Indications
- When no other options possible – as risk of ankylosis
Impacted canine
Survival & success
- Survival 68-88% 75% average
- Success : around 50% Kallu 2005
Indications
- Unlikely upper arch: as orthodontic treatment 97% successful
- Severely ectopic mandibular canines, to prevent transmigration
