Inventions herein include at least mostly optically clear orthodontic braces and feet orthotics (collectively referred to as “appliances”) with backscatter based sensors. These two categories of appliances share a common property requiring that the given appliance must be correctly custom manufactured to fit a patient's own particular geometry and dimensions of their teeth and/or feet in order to perform as intended. Incorporating such appliances with backscatter based sensors enables simple, easy, fast, efficient, and cost effective measurements, in real-time or near real-time, of stresses, forces, structural changes, and/or the like in the given appliance; which in turn can aid in determining if adjustments or re-manufacture of the appliance may be needed or desired; and/or wherein such measurements may aid in evaluating performance of the given appliance. In some embodiments, such measurements may also be taken remotely away from a practitioner; and then communicated to a remotely located practitioner.
