The bite correction appliance category at CFL includes thermoformed or acrylic retainer-style devices with integrated anterior bite guidance elements. The "Invisible with Anterior Bite" combines a clear thermoformed retainer with an anterior acrylic bite ramp — useful for maintaining bite opening or correcting mild Class II. The "Invisible with Incline Plane" incorporates an anterior incline plane for Class III anterior crossbite correction (the lower incisors contact the incline and are guided distally). The "Dual Bite Block Retractors" is a more complex bilateral block system, potentially used for bite correction in multiple planes. These devices bridge the gap between passive retention and active bite correction.
Incline plane (Class III): Lower incisors contact an angled acrylic ramp on the upper retainer during closure, producing a distal force on the lower anterior teeth and a forward force on the upper anteriors — correcting anterior crossbite. Most effective in mixed dentition (growing patients with an accommodative bite). The incline plane angle (typically 45–60°) determines the force direction.
Anterior bite ramp (Class II/deep bite): Upper anterior coverage with a bite ramp that contacts the lower incisors and holds the mandible in a slightly forward position, preventing the lower anteriors from occluding deeply. Simultaneously opens the posterior bite to allow posterior eruption (bite plate function).
Dual bite blocks: Bilateral blocks that prevent full posterior closure, used for vertical dimension control or combined anteroposterior + vertical bite correction.
Anterior crossbite in mixed dentition where the incline plane can redirect lower incisor eruption; Class III tendency with dental (not skeletal) anterior crossbite; deep overbite maintenance during retention; mild Class II correction during the retention phase; cases where a passive retainer would lose bite correction already achieved in treatment.
Incline plane correction only works in growing patients with accommodative bite — adult anterior crossbites are skeletal and require orthognathic surgery or comprehensive retreatment. High-angle patients should avoid anterior bite ramps (worsens vertical). Compliance-dependent.
into the thermoformed base)
The incline plane angle must be specified by the ordering doctor — standard is 45–60° from horizontal. The acrylic ramp must be smooth and polished to prevent tongue irritation. For the dual bite block version, bilateral symmetry is critical — uneven blocks deliver asymmetric forces. CFL pricing: Inv. W/ Ant Bite Inv Ret w/ Incline Plane , Dual Bite Block Retractors.
