The fixed bite plate is a bonded anterior appliance providing bite opening function without patient compliance. Acrylic pads (or composite builds) are bonded to the lingual surfaces of the upper anterior teeth (typically upper central and lateral incisors), creating a shelf that the lower incisors contact when the patient bites. This disarticulates the posterior teeth and allows them to erupt, opening the bite. Unlike the removable anterior bite plate (Bite plate), the fixed version works 24/7 without patient cooperation — ensuring continuous posterior disarticulation. Often used at the start of comprehensive fixed appliance treatment to correct deep bite before full-bracket bonding.
Same as removable bite plate (Bite plate): posterior disarticulation → posterior eruption → bite opening. The fixed design eliminates compliance as a variable. Lower incisor contact on the bonded shelf creates a stop that holds the anterior teeth while allowing posterior teeth to erupt. Duration of treatment: typically 3–6 months for meaningful bite opening. After adequate bite opening, full fixed appliances can be placed without the bite plate blocking bracket placement.
Deep overbite at start of comprehensive treatment; patients where compliance for removable bite plate is poor; adults with deep bite requiring definitive correction; cases where posterior eruption is the primary vertical correction strategy; combination with full fixed appliances (bite plate bonded before or simultaneously with bracket placement).
Fixed design means the bite plate cannot be removed by the patient — the lower incisors are always contacting the shelf, which can feel unusual initially. A bite plate that is too thick may initially feel uncomfortable on closure. Bonding failure (plate debonding) returns the deep bite position. Not appropriate for hyperdivergent patients.

Pads must be shaped precisely to the lingual surface of the upper anterior teeth (using a stone model) so they adapt closely and bond successfully. The shelf surface must be flat and even. Acrylic must be polished smooth. CFL offers the Fixed Bite Plate under OA-0316 and the Mod Fixed Bite Plate; OA-0325 likely represents the specific bonded pad design. See also Acrylic plate retainer.
