ORTHODONTIC BRACES AND FEET ORTHOTICS WITH BACKSCATTER BASED SENSORS
20220409342 · 2022-12-29 ·

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.

Preformed dental composite crown, process of production and use thereof

The invention relates to a preformed dental composite crown being characterized by its shape and chemical composition, the shape being characterized as follows: having an occlusal top surface and depending buccal, mesial, distal and lingual side surfaces, the side surfaces being connected to each other and forming a crown cervix, the wall thickness of the crown at the crown cervix being lower than 0.6 mm; at least two of opposing depending side surfaces having a concave shape; the chemical composition of the material the preformed dental composite crown is made of being a hardened composition comprising the following components: nano-filler(s) in an amount from 20 to 70 wt. %, resin matrix in an amount from 20 to 75 wt. %, wt. % with respect to the weight of the chemical composition, the resin matrix comprising urethane(meth)acrylate(s) and (meth)acrylate(s) not comprising a urethane moiety. The invention also relates to a kit of parts comprising such a preformed dental composite crown, processes for producing such crowns and the use of such a crown for treating a dental tooth.
