Setup with a template
In the mandible, the teeth can be set up in either one of two versions: setup with or setup with-
out curve of Wilson. Since all working contacts are lingualized and the buccal surfaces do not
occlude, there is some scope for variation in the degree of the curve of Wilson.
Align the template with the height of the distal third of the retromolar pad in the posterior region
and the height of the distal angle of the mandibular canines in the anterior region.
Setup method WITHOUT curve of Wilson
The buccal cusps do not touch the template in this
setup method. Make sure that the buccal and lingual
cusp tips are on the same plane.
The fissure centre of the mandibular posterior teeth is
aligned with the alveolar ridge. The mandibular
posteriors must not extend beyond Pound's line towards
the lingual.
The contacts to the template are concentrated on the
lingual cusp tips to achieve a setup that has only a
sagittal compensating curve. Viewed from the buccal,
the axis of the posterior teeth should be aligned
perpendicular to the template.
To achieve a horizontal alignment of the cusp tips on
the first premolar, the buccal cusp may be brought into
contact with the template.
optional
Setup method WITH curve of Wilson
If the curve of Wilson is taken into account in the set-
up of the Lingual moulds, contacts between the
template and the buccal and lingual cusps are required.
