Maxillary vs Mandibular Canines Flashcards
Crown wider Mesiodistally
Maxillary
Cusp angle sharper, more acute (105) degrees
Maxillary
Mesial cusp ridge shorter than distal
Maxillary
Mesial, distal proximal contacts more cervical
Maxillary
Mesial of crown bulges beyond root outline
Maxillary
more pronounced labial ridge
Maxillary
More pointed root tip
Maxillary
Crown Narrower Mesiodistally
Mandibular
Cusp angle more blunt (120) degrees
Mandibular
Mesial cusp ridge much shorter than distal
Mandibular
Mesial cusp ridge almost horizontal
Mandibular
Mesial, distal proximal contacts more incisal
Mandibular
Mesial crown outline almost continuous with root with little or no bulge
Mandibular

Mandibular
More blunt tip
Mandibular
Crown outline more convex on distal
Maxillary
Crown outline more convex on distal, mesial crown outline aligns with root
Mandibular
Mesial cusp ridge almost horizontal
Mandibular
Has distal crown outline more convex than mesial crown outline
Maxillary and Mandibular

Maxillay and Mandibular
Has mesial cusp ridge shorter than distal
Maxillary and Mandibular
Proximal contacts (Height of Contour) Maxillary Canine Mesial Surface
Incisal/Middle Junction
Proximal contacts (Height of Contour) Mandibullar Canine Mesial Surface
Incisal third (just cervical to mesioincisal angle)
Proximal contacts (Height of Contour) Maxillary Canine Distal Surface
Middle Third (most cervical of anterior teeth)
