Lingualized occlusion
The basic characteristics of lingualized occlusion have
been incorporated into the design of the SR Phonares II
Lingual moulds.
The maxillary palatal cusps provide centric contacts
which articulate to the respective mandibular fossae.
The buccal cusps are not set in contact.
An additional buccal contact may be established on the
first premolars for esthetic reasons.

The marginal ridges of the
Lingual moulds have been
given reduced contours so
that the maxillary palatal
cusps remain free during
protrusive or retrusive
movements. Depending on the occlu-
sal position and the setup
of the anterior arch, it is
possible to establish a
one-to-two intercuspation.
