The ORS-DE is an economical resilient type partial denture attachment with a
plastic castable male. The ORS-DE transfers less stress to the abutment than
any other attachment. The retentive O-Rings are easily replaceable. The
metal retainer ring reduces maintenance to a minimum. Each ORS-DE
includes: 1 ORS-DE castable male pattern, 1 gold plated stainless steel
retainer ring, 1 brass analog, 3 white, and 3 red O-Rings. A micro size distal
extension can be created by waxing an extension to a micro OD male - refer
to the stud type section under ORS-OD Micro.
