  • Patent number: 11094120
    Abstract: An inspection processing system includes a control unit connected to a photographing unit and an output unit. The control unit includes circuitry. The inspection processing system identifies a current position, displays a virtual image of a three-dimensional model of a structure corresponding to the current position. The virtual image is superimposed on a structure image obtained from the photographing unit. The inspection processing system further obtains an evaluation result of an evaluation item of an inspection subject using the structure image on which the displayed virtual image is superimposed, and records the evaluation result in an inspection information memory in association with the position of the inspection subject in the three-dimensional model.

  • Patent number: 10596301
    Abstract: This disclosure provides a product comprised of a collagen gel to which recombinant human Amelotin (AMTN) protein is added. This AMTN-collagen gel is applied to one side of a physiologically acceptable scaffold that has first been impregnated with AMTN-free collagen gel. The resulting two-layer collagen membrane (layer 1 comprised of scaffold surrounded by collagen gel; layer 2 comprised of collagen gel containing AMTN) is applied to a mineralized tissue surface such as dentin and bone with the collagen gel containing AMTN of layer 2 facing this mineral surface. Upon immersion in simulated body fluid (SBF), the presence of AMTN in layer 2 triggers the formation of hydroxyapatite mineral deposits that intimately connect with the existing mineral surface and thus provide physical attachment. A similar product is disclosed but in addition to AMTN, it contains the Odontogenic, Ameloblast-Associated (ODAM) protein as well with both proteins exhibiting a synergistic effect.
