ARK's Jaw Grading Bite Blocks are a specialist oral motor tool designed to develop jaw grading and stability - the controlled jaw movements needed for speech and feeding skills. Each set includes 3 colour-coded blocks with 6 different arm thicknesses, plus instructions with four targeted exercises. What is Jaw Grading & Stability? Jaw grading is the ability to move the jaw to various controlled heights needed for speech and feeding. For example, note the difference in your jaw when saying "eee" vs "ahhh", or biting into a cracker vs a sandwich. Jaw stability is the strength, coordination, and endurance to do so without the jaw sliding forward or sideways. These Bite Blocks are firm enough for good resistance during exercises, but not 100% rigid - gentle on the teeth. Each arm also has sensory bumps to grip the teeth.
