made up of the triangular ridges of a buccal and lingual cusp which join to form more or less continuous elevation extending transversly accross the occlusal surface of a posterior tooth

In this normal relationship, the maxillary first molar is slightly
posterior to the mandibular first molar:  the mesiobuccal cusp of the
maxillary first molar is directly in line with the buccal groove of the
permanent mandibular first molar.  The facial profile is termed
mesognathic.

the maxillary first molar is slightly posterior to the mandibular first
molar:  the mesiobuccal cusp of the maxillary first molar is directly
in line with the buccal groove of the permanent mandibular first molar. what class?

what is the relationship of the posterior teeth of a class I

what relationship are the canines in in a class I occlusion

What class

In this classification, the maxillary first molar is even with or
anterior to the mandibular first molar:  the buccal groove of the
mandibular first molar is distal to the mesiobuccal cusp of the
maxillary first molar.  The facial profile is termed retrognathic.

What class?

occurs when the permanent first molars are in class II and the
permanent maxillary central incisors are in their normal or slightly
protruded position.

occurs when the permanent first molars are in class II and the permanent
maxillary central incisors are retruded (pulled backward toward the
oral cavity) and tilting lingually.

MB cusp of the maxillary first occludes (by more than the width of a premolar) mesial to the MB groove of the mandibular first.

Distal surface of the mandibular canine is distal to the mesial surface
of the maxillary canine by at least the width of a premolar.

Maxillary anteriors protrude facially from the mandibular anteriors, with deep overbite. what division of Class II

Maxillary central incisors are either upright or retruded, and lateral
incisors are either tipped labially or overlap the central incisors with
deep overbite. what division of Class II

In this classification, the maxillary first molar is more posterior to
the mandibular first molar than normal:  the buccal groove of the
mandibular first molar is mesial to the mesiobuccal cusp of the
maxillary first molar.  The facial profile is termed prognathic.

MB cusp of the maxillary first occludes (by more than the width of a premolar) distal to the MB groove of the mandibular first.

Canines:  Distal surface.

Mandibular incisors in complete crossbite.

In a deep bite (over bite), the maxillary incisors vertically overlap
the mandibular incisors excessively.  (In severe cases, mandibular
incisors may contact the palate or maxillary incisor may strike lower
gingiva.)

there are areas where the maxillary and mandibular teeth do not touch. can sometimes be attributed to thumb sucking or a tongue thrust.  Other times the condition is a skeletal problem.)

refers to the distance between the facial surfaces of the maxillary
incisors and the facial surfaces of the mandibular incisors.

located lingually (to the inside of) the teeth of the mandibular jaw.
