Highwater
Design with primary substructure
This
design will allow you a proper correction
of implant angulation in its resorbed
maxillary ridge and prevents screw holes
in aesthetic areas.
A restoration
of this type is constructed with a primary
bar that is secured to the implant,
and a secondary casting that fits over
the primary bar. The secondary casting
is retained by lingual screws.

Finished case
This
design has been unpopular among the
dentists because of the difficulties
of handling custom slotted screws from
the palatal surface in the mouth.
Solution
Thanks
to Dr. Davidoff we have a solution to
this problem. Today we have standardized
screws for both primary and secondary
frames. These screws are all hexed.
They can be inserted and removed easily
in the mouth. For more information refer
