Preparation method of dental restoration with low food impaction rate

The invention discloses a preparation method of a dental restoration with a low food impaction rate, which is applied to the field of medical treatment and public health and comprises the following steps: acquiring full-surface three-dimensional data of a tooth area to be restored; on the basis of the full-surface three-dimensional data, designing a complete three-dimensional form of the prosthesis, and designing a filling hole type on an adjacent surface area, adjacent to the teeth, of the prosthesis to obtain three-dimensional data of the prosthesis; and based on the three-dimensional data of the prosthesis, manufacturing the prosthesis, filling the filling hole type during intraoral try-on and adjustment in place, and taking out to obtain the final prosthesis. In the design process of the complete three-dimensional shape of the prosthesis, the filling hole type is designed in the adjacent surface area, adjacent to the teeth, of the prosthesis, the prosthesis is tried in the mouth of the prosthesis, and the
