Excessive material on the sides and bottom of the half-sole add-on is removed with the grinder. This process allows the practitioner to grind functional angles in the orthotic as well as achieve a level plane on the bottom surface.
When grinding is completed, the product can then be easily posted on the rearfoot or the forefoot to achieve the desired biomechanical effects. This completes the Finishing process.
An orthotic blank is chosen based on the patients’ clinical evaluation. The orthotic blank is then heated in a convection oven at 250°F for 3-4 minutes until the inner vinylplex core becomes malleable.
The heated blank is placed on the suspension pillows of the molding stand and the patient’s feet are placed on the heated orthotic blanks. Use the markings on top of each pillow to assist in determining proper heel placement of the heated orthotics.
Position the adjustable knee bar of the molding stand to a 45° angle to the patient’s patellas. The patient’s knees are placed against the knee bar, simulating mid-stance.
