Show Answers:

  1. Anterior Teeth:
    • Incisors and Canines
    • Incisal edge or one cusp
    • Cingulum and lingual fossa(e)
    • Marginal ridges parallel long axis
    • Facial and lingual heights of contour in cervical third
  2. General Canine Features
    • Single cusp (cuspid)
    • Favorable crown to root ratio
    • Transitional form: mesial (anterior) and distal (posterior)
    • Longevity
  3. Canine Facial Surfaces
    • Sharp cusp tip
    • Labial ridge
    • Dev Depressions
    • Mesial and distal cusp slopes or ridges
  4. Canine Lingual Surfaces
    • Lingual ridge
    • Lingual fossae
    • Marginal ridges
    • Cingulum
  5. Maxillary Canine
    • Longest root
    • Bulky crown with prominent ridges
    • Well-developed lingual anatomy
    • Asymmetry: mesial aspect like anterior tooth; distal is more like a posterior tooth
  6. Mandibular Canine
    • Long, narrow crown with smooth lingual surface
    • Mesial cusp ridge much shorter than distal cusp ridge
    • Incisocervical crown length longer than for maxillary canine
  7. What is the only dimension of the mandibular canine that is greater than that of the maxillary canine?
  8. Intercuspal Position (ICP)
    • Most interdigitated (closed) position of maxillary and mandibular teeth
    • �Close on your back teeth�.
    • Different occlusal relationships
    • Protrusive (Forward) Movement
    • Lateral Movement from ICP
    • Functional Canine Wear
  9. Arch Form Relationships and Considerations
    • Proximal contacts
    • Location
    • Size
    • CEJ curvature
    • Marginal ridge height
    • Embrasure symmetry
  10. Location of Proximal Contacts
    • Proximal contacts move from incisal to middle third
    • in progression from midline to distal of the canine.
  11. Pattern of CEJ Curvature
    • Describe the change from anterior to posterior
    • .
  12. Marginal Ridge Height
    • What is the clinical consequence when adjacent
    • marignal ridges are not the same height?
  13. Symmetry of Embrasures
    • The occlusal/incisal aspect is best for viewing buccal/facial and lingual embrasures.
    • The facial aspect is best for viewing the occlusal/incisal and cervical embrasures.
