This prefabricated unit facilitates fabrication of a sectioned bridge with occlusal screw.
|The titanium screw has a hexagonal socket to facilitate
|The circumferential ring marks the maximum level to
which it can be
|The paralleling mandrel positions the sectioning
|The design and minimal dimensions of the threaded
sleeve in the sectioning
attachment enable it to be adapted to the papillae as required.
|The threaded sleeve is made of a cast-on alloy and can
be used with
any gold or semi-precious alloy.
|The retention rod should be coated with colloidal
graphite and retains
the threaded sleeve precisely in the investment material.
|The section connecting the attachment to the coping is
a diameter of 1.0 mm and can be trimmed accurately with a 1.0 mm rotary
cutter if required.
|The circumferential ledge on the locking ring marks the
level to which
the screw and locking ring can be reduced.
|To ensure that the locking ring is fixed in place
securely, the outer
section must be moulded with Pi-Ku-Plast brush-on
|The exterior design of the locking ring which consists
of a cast-on
gold alloy, ensures that it is retained securely in resin.
|The bridge patter is waxed up onto the resin outer
|The titamium screw can be ground to blend it into the
