Certified offers two custom UCBL styles. The classic thermoplastic Rigid UCBL and the soft UCBL. The Rigid UCBL is fabricated with polypropylene plastic and posted to neutral. The Soft UCBL incorporates softer padding materials and a semi-rigid thermoplastic to address patients who require containment of a UCBL, while offering cushioning and a less rigid option. We accept impression kits, casts and scans to fabricate custom UCBL’s.
