buccallyeruptedmaxillarycanine

1. MALPOSED CANINE

2. ●Causes
1Crowding
- Maxillary canine is usually the last tooth to erupt anterior
to the first permanent molar.
If the upper arch is crowded , maxillary canine may be
squeezed buccal to it normal position.
2Retention of primary canine
3-Supernumeraryteeth
Buccally erupted maxillary canine

5. Totally blocked outbuccally erupted maxillary canines

8. Figure –
Maxillary permanent canines palpable in the buccal sulcus.
The canine position is given away by the inclination of the
permanent lateral incisor crowns.

9. Possible means for creatingspace for correction of
crowding
1-Enamel stripping (Disking)
2-Arch expansion
3-Distal movement ofmolars
4-Extraction
5-Any combination of theabove

10. Transposition of maxillarycanine
- In the maxillary canine is usually transposed with first
premolar and in the mandible lateral incisor is more
commonly involved.
Treatment options
-Alignment of teeth in transposed position.
-Extraction of the most displaced tooth ,
-Treat the other orthodontic problems

11. Transposition 3 (Ectopic erupted 3)

12. Transposition 3 and retainedc

13. Palatally displaced maxillary canineor
palatalcanine
Possible causes
1 Genetic.
2 Crypt displacement .
3 Maxillary canine has the longest path of eruption of any
permanent tooth.
4 Arch length discrepancy.
5 Trauma to the maxillary anterior area at an early stage of
development .
