  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
  3. Totally blocked outbuccally erupted maxillary canines
  4. Figure – Maxillary permanent canines palpable in the buccal sulcus. The canine position is given away by the inclination of the permanent lateral incisor crowns.
  5. 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
  6. 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

  9. 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 .
