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
General Canine Features
- Single cusp (cuspid)
- Favorable crown to root ratio
- Transitional form: mesial (anterior) and distal (posterior)
- Longevity
Canine Facial Surfaces
- Sharp cusp tip
- Labial ridge
- Dev Depressions
- Mesial and distal cusp slopes or ridges
Canine Lingual Surfaces
- Lingual ridge
- Lingual fossae
- Marginal ridges
- Cingulum
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
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
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
- Proximal contacts
- Location
- Size
- CEJ curvature
- Marginal ridge height
- Embrasure symmetry
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.
