- Decision making of impacted canines? Zeno 2018
- If canine overlaps mesial aspect of central incisor – poor prognosis
- Angle of 30 degrees + poor prognosis
- Extraction of deciduous canines?
- Normova 2018: Yes if PDC in sector 2-3 ideal of extraction of primary canine
- CBCT is it required?
- AAOMR position paper: CBCT must be justified on an individual bases
- Bjoksved 2019: compared plane view radiographs in canine evaluation Vs CBCT: good agreement
- CBCT more accurate – BUT may not make a difference to patient outcomes
- Follicle? Ericson 2001
- Normal size = 2.3-2.7
- Ectopic size = 2.7-3.2
- Large variation, CV cannot distinguish pathological follicle from normal, difficult to predict when to intervene
- Timing and sequence of events?
- Interceptive treatment removing supernumerary teeth may not resolve impaction, unclear ideal time
- Timing for ideal time for exposure?
- 8 years is the ideal time to decide on active traction or observe – opinion Becker, no published evidence
- Can canine impaction be predicted?
- Uribe 2016 – no specific variable of canine impaction prediction – radiographs, study models.
