Transcript

  • 1. CANINES DR. SYED SADATULLAH IBNSINA NATIONAL COLLEGE JEDDAH
  • 2.  
  • 3. <ul><li>Maxillary Canine </li></ul><ul><li>Labial aspect </li></ul><ul><li>The crown of maxillary canine is narrower mesiodistally than that of maxillary central incisor. </li></ul><ul><li>The incisal aspect has a large cusp with a pointed cusp tip </li></ul><ul><li>It has two slopes (cusp ridges), the mesial slope being shorter than the distal slope </li></ul><ul><li>The labial surface is smooth and bulky in the middle because of the labial ridge </li></ul>
  • 4. Labial aspect Labial ridge Cusp tip Distal cusp ridge Mesial Cusp Ridge
  • 5. <ul><li>Lingual aspect </li></ul><ul><li>The crown and root are narrower lingually </li></ul><ul><li>The cingulum is well developed, large and sometimes pointed like a cusp </li></ul><ul><li>Occasionally a well developed lingual ridge is seen that divides the lingual fossa into mesial and distal lingual fossae </li></ul><ul><li>Heavy marginal ridges are associated with well formed cingulum and fossae </li></ul>
  • 6. Lingual aspect Cingulum Distal marginal ridge Distal lingual fossa Lingual ridge Mesial marginal ridge Mesial lingual fossa
  • 7. <ul><li>Mesial aspect </li></ul><ul><li>From the mesial aspect canine looks similar but bulkier than maxillary central incisor </li></ul><ul><li>Maxillary canine is the widest anterior tooth labiolingually </li></ul><ul><li>The cervical line curvature is towards the cusp (incisally) </li></ul><ul><li>The contact area is near the junction of the incisal and middle third </li></ul>
  • 8. Mesial aspect
  • 9. <ul><li>Distal aspect </li></ul><ul><li>Distal surface is very similar to the mesial surface </li></ul><ul><li>The cervical line exhibits less curvature </li></ul><ul><li>The contact are is near the middle third </li></ul>Distal aspect
  • 10. <ul><li>Incisal aspect </li></ul><ul><li>The labiolingual dimension is greater than the mesiodistal dimension </li></ul><ul><li>The cusp tip is labial to the centre of the crown labiolingually and mesial to the centre mesiodistally </li></ul><ul><li>The labial ridge and the cingulum are very noticeable from this aspect </li></ul>Incisal aspect
  • 11. <ul><li>Root – only one </li></ul><ul><li>The root is the longest and strongest of all the teeth in the dentition </li></ul><ul><li>The mesial and distal surfaces of the root have developmental depressions . </li></ul>2.5 1.5 7.0 8.0 5.5 7.5 17.0 10.0 Curvature of Cervical Line M D Labiolingual Diameter at Cervical Line Labiolingual Diameter at Crest of Curvature Mesiodistal Diameter at Cervical Line Mesiodistal Diameter at Contact Area Root Length Crown Length Average Dimensions in millimeters
  • 12. <ul><li>Mandibular Canine </li></ul><ul><li>Labial aspect </li></ul><ul><li>Mandibular canines are similar to maxillary canines except that they are slightly narrower mesiodistally </li></ul><ul><li>Mesial outline of the crown is straight and inline with the mesial outline of the root </li></ul><ul><li>The mesial cusp ridge is smaller than the distal cusp ridge </li></ul>
  • 13. <ul><li>Lingual aspect </li></ul><ul><li>The lingual surface of the crown is smooth and flat simulating the surface of mandibular lateral incisor </li></ul><ul><li>Cingulum is less prominent and marginal ridges are less distinct </li></ul><ul><li>Mesial and Distal aspects </li></ul><ul><li>These aspects are very similar and the cervical line curves more on the mesial aspect </li></ul><ul><li>The contact area on mesial aspect is in the incisal third and a little higher on the distal third </li></ul>
  • 14. <ul><li>Incisal aspect </li></ul><ul><li>Like maxillary canine the labiolingual dimension is more than the mesiodistal dimension </li></ul><ul><li>The cusp tip appears inclined in a lingual direction </li></ul><ul><li>Root </li></ul><ul><li>The root is shorter by 1 or 2 mm </li></ul><ul><li>The developmental depression is more pronounced on the lower canine </li></ul>
  • 15. Labial aspect Lingual aspect Mesial aspect Distal aspect Incisal aspect
