FR Attachment
The FR system for removable
partial dentures is a technological revolution for what many call
semi-precision or "mill-ins." A tapered, friction retained intracoronal
precision attachment for removable partial dentures with a lingual arm and
for segmented bridgework or non-parallel abutments in fixed bridgework. The
female is actually cast against the prefabricated male for total accuracy,
improved proximal wall contacts, and tremendous time and labor savings. This
simple and inexpensive attachment uses a single investment technique,
eliminates porcelain in the female due to the silicone male, allows for easy
and accurate duplication, no soldering is needed, easy separation of male
and female, and the miniature size allows for use in ‘close bite’
situations. Easy insertion because of the tapered male, improved esthetics
(no metal on the occlusal), excellent retention and reduced wear account for
this being one of the most popular attachments in dentistry.

UNOR Instructions
Not available
The UNOR is a screw adjustable retention
precision attachment for intracoronal use. The beveled male is adjustable so
retention may be either increased or decreased, allowing for easy patient
insertion and removal, thus less wear. Vertical height may also be altered
for short or ‘close bite’ situations. The female may be directly cast with
precious or semi-precious alloys for easy fabrication. A female ceramic
former is available for creating a female in non-precious castings. The
excellent external wall contact allows for guide plane stability. The male
may be connected to the cast frame by acrylic resin, composite resin, or
solder. The system also allows for conversion of a fixed bridge to a
removable partial denture if distal abutments are lost. |
