A method of repairing an oral defect model includes performing a three-dimensional oral defect model obtaining step, a defect cutting line detecting step, a defect point selecting step and a smoothing step. The three-dimensional oral defect model obtaining step is performed to scan an oral cavity to obtain a three-dimensional oral defect model message. The defect cutting line detecting step is performed to detect a defect cutting line of the three-dimension oral defect model message, and drive a displayer to display the defect cutting line. The defect point selecting step is performed to select at least one defect feature point of the defect cutting line via the displayer. The smoothing step is performed to perform a smoothing process at the at least one defect feature point, and convert the three-dimensional oral defect model message into a three-dimensional oral repaired model message to smooth the defect cutting line.

According to the present disclosure, an oral rehabilitation device includes an air bladder and a pumping member. The air bladder includes a cheek-side membrane and a teeth-side membrane, and the cheek-side membrane and the teeth-side membrane are arranged opposite to each other. The pumping member is communicated with the air bladder, and the pumping member is configured for inflating the air bladder. The cheek-side membrane and the teeth-side membrane extend toward the outside of the air bladder when the pumping member is inflating the air bladder, and an extension of the cheek-side membrane is larger than an extension of the teeth-side membrane.

A three-dimensional serial focused intraoral digital tomosynthesis scanner includes a frame body, an image capturing module, a photosensitive member and an image processing module. The frame body includes a central axis and a light source seat which is moved along a scanning path and rotated around the central axis. The image capturing module is disposed on the light source seat and reciprocated along the scanning path. The image capturing module is configured to generate a light beam emitted from an outside to the patient's mouth. The photosensitive member is positioned in the patient's mouth. The light beam is emitted to the photosensitive member and moved along the scanning path corresponding to the photosensitive member so as to generate a plurality of two-dimensional optical images by the image capturing module. The image processing module calculates the two-dimensional optical images to generate a three-dimensional image.
