Standard C/ | Crowns and bridges
Suprastructures are screw-retained occlusally on
straight Ankylos Standard C/ abutments, and laterally
on angled abutments.
Screw-retained suprastructure
Mount the wax-up copings
with wax-up screws (order no.
3104 5211/short or 3104 5213/long)
and mark the required length.
Shorten the wax-up screws
corresponding to the occlusal
proportions and, using a thin
cutting disk, make a new slot.
Then fix these in the laboratory
analogs.
Depending on the screw-retention
type, seal the hole not required
with wax. By doing so, ensure that
no wax gets into the inside of the
copings.
These directions show the
fabrication of an occlusally
screw-retained bridge. If lateral
screw-retention is planned,
please observe the directions on
page 96/97.
