OA-0145 is a general-purpose retention category at CFL encompassing several retainer types not captured under more specific product IDs. Key products include: the Invisible Retainer (thermoformed clear, Essix-type), the San Antonio Retainer (a flat-arch-form wire retainer), the L. Phase One Hybrid Retainer (lower phase I mixed dentition retainer), and the L Flat Wire Retainer. These represent CFL's retention solutions for diverse clinical scenarios across phase I treatment, comprehensive treatment, and specialty retention needs.
Each retainer type maintains teeth in their post-treatment positions by encapsulating or contacting the tooth surfaces. Thermoformed clear retainers (Invisible Retainer) use full-arch coverage. Wire retainers use labial bow contact. Phase I retainers are designed to accommodate the mixed dentition, with spaces for erupting permanent teeth built into the design.
Invisible Retainer: Standard clear thermoformed retention; Essix-type; upper or lower. Invisible Retainer with Palate: Clear with additional palatal reinforcement. L. Phase One Hybrid Retainer: Lower arch phase I retainer combining lingual arch and thermoformed elements. L Flat Wire Retainer: Flat ribbon/wire labial retainer with acrylic backing. San Antonio Retainer : Premium flat-arch wire retainer — smooth, polished, full labial contact.
Each variant has specific compliance requirements (removable) and indication ranges. Phase one retainers must be updated as the dentition develops.
for comfortable full-labial contact
Phase one hybrid retainer requires careful design to accommodate erupting teeth — spaces must be provided for unerupted premolars/canines while holding the existing arch form. San Antonio retainers use a flat/ribbon wire for smooth labial feel; the wire must follow the labial contour precisely. Flat wire retainers reduce wire-to-soft-tissue friction compared to round wire.
