Card Set Information
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
General Canine Features
Single cusp (cuspid)
Favorable crown to root ratio
: mesial (anterior) and distal (posterior)
Canine Facial Surfaces
Sharp cusp tip
Mesial and distal cusp slopes or ridges
Canine Lingual Surfaces
Bulky crown with prominent ridges
Well-developed lingual anatomy
: mesial aspect like anterior tooth; distal is more like a posterior tooth
Long, narrow crown with smooth lingual surface
Mesial cusp ridge much shorter than distal cusp ridge
Incisocervical crown length longer than for maxillary canine
What is the only dimension of the mandibular canine that is greater than that of the maxillary canine?
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
Arch Form Relationships and Considerations
Marginal ridge height
Location of Proximal Contacts
Proximal contacts move from incisal to middle third
in progression from midline to distal of the canine.
Pattern of CEJ Curvature
Describe the change from anterior to posterior
Marginal Ridge Height
What is the clinical consequence when adjacent
marignal ridges are not the same height?
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.
