This device postures the patient forward by using the acrylic blocks. The patient can only bite in the forward position as the block disallows biting in the normal position. This causes a stretch in the muscles causing movement. What is the purpose of using acrylic blocks in this device?
1) To prevent the patient from biting in the normal position
2) To provide support for the patient's jaw
3) To improve the patient's posture
4) To stretch the patient's muscles
