Anterior restorations
with 4 units and more
Place the restorations on their
incisal surface. Make sure the
pontics are supported. Depending on the curvature,
the framework can be placed on
its labial surfaces. All the pontics
must come into contact with
the sinter tray. Abutment
crowns do not necessarily have
to be in contact with the sinter
tray. Restorations should not solely
rest on their marginal edges.
Posterior restorations
with 4 units and more
Depending on the curvature,
the restoration can be placed on
its buccal surfaces. All the
pontics must come into contact
with the sinter tray. Abutment
crowns do not necessarily have
to rest on the sinter tray. Restorations should not solely
rest on their marginal edges
(crown margins). The pontics
should be supported on the
basal side. If the restoration does not rest
on the pontics, do not place it
on its occusal surface.
Restorations with sinter
support structure
Place the restoration on the
sinter tray with the sinter
support structures resting on
the tray. The restoration can also be
placed on the sinter support
structure / incisal or occlusal
surfaces of the pontics. The
sinter support structure should
face the centre of the sinter
tray. Restorations should not rest on
the crown margins.
