The Esthetic and Functional Parameters of Posterior Teeth
Contact points generated by mandibular teeth on maxillary teeth (Angle Class I)
1A: Points of contact on the distal transverse ridge of the buccal cusp of the mandibular first premolar and the mesial marginal ridge of the maxillary first premolar.
2A: Point of contact where the mesial transvers ridge of the buccal cusp of the mandibular second premolar touches the distal marginal ridge of the maxillary first premolar.
3A: Point of contact where the distal transverse ridge of the buccal cusp of the mandibular second premolar touches the distal marginal ridge of the maxillary second premolar.
4A: Point of contact where the mesial transvers ridge of the mesiodistal cusp of the mandibular first molar touches the distal marginal ridge of the maxillary second premolar.
5A: Point of contact where the distal segment of the transvers ridge of the mesiobuccal cusp of the mandibular first molar touches the mesial marginal ridge of the maxillary first molar.
6A: Point of contact where the mesial slope of the medial cusp of the mandibular first molar touches the crest ridge of the mesiobuccal cusp, near the central fossa, of the maxillary first molar.
7A: Point of contact where the distal slope of the medial cusp of the mandibular first molar touches the crest ridge of the distobuccal cusp, near the central fossa, of the maxillary first molar.
8A: Point of contact where the middle of the crest ridge of the medial cusp of the mandibular first molar touches the middle of the crest ridge of the mesiolingual cusp of the maxillary first molar.
9A: Point of contact where the mesial transverse ridge of the mesiobuccal cusp of the mandibular second molar touches the distal marginal ridge of the maxillary first molar.
10A: Point of contact where the distal transverse ridge of the mesiobuccal cusp of the mandibular second molar touches the mesial marginal ridge of the maxilllary second molar.
11A: Point of contact where the mesial slope of the distobuccal cusp of the mandibular second molar touches the crest ridge of the mesiobuccal cusp, near the central fossa, of the maxill...
