Bredent oc Bridge Sectioning Attachment

This prefabricated unit facilitates fabrication of a sectioned bridge with occlusal screw.

The titanium screw has a hexagonal socket to facilitate tightening and loosening.

The circumferential ring marks the maximum level to which it can be shortened,

Premanufactured abutment.

The paralleling mandrel positions the sectioning attachment correctly.	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 rounded, has 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 resin.	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 section.	The titamium screw can be ground to blend it into the occlusal surface.
