Intercuspation
The maxillary teeth can now be aligned with the
mandibular teeth in a one-tooth-to-one-tooth relation-
ship to achieve optimum intercuspation.
• After the mandibular teeth have been set up in
compliance with the findings of the model analysis,
the mandibular 1
st molar is usually positioned at the
lowest point of the alveolar ridge. The lingual cusps
of the maxillary molar form the static chewing centre.
• The palatal cusp of the maxillary premolar engages
the fossa of the mandibular premolar.
As an option, it is possible to establish a contact
relation between the mandibular buccal cusp and the
central fossa of the maxillary premolar to achieve an
esthetic transition from the canines to the premolars
and to establish a buccal corridor.
• The distance between the buccal cusps increases
along the dental arch due to the Monson curve.
