  • Publication number: 20230200937
    Abstract: Proposed is a hybrid ceramic prosthesis. Since the prosthesis is made of a novel hybrid ceramic material, the prothesis has a similar color and transmittance to natural teeth, minimizes tooth removal during preparation for placement of the prothesis, is securely attached to the target tooth by snap-fit fastening to prevent detachment of the prothesis and re-treatment caused by the prothesis detachment, and can be more conveniently applied to the patient than conventional prostheses, enabling an one-day-one-stop dental procedure, thereby reducing burden to patients. The prothesis is useful as a primary crown.
