PROBLEM TO BE SOLVED: To provide a dental prosthesis that is easy to be inserted and removed without damaging teeth and prostheses there, and can securely stay within the mouth of a patient without using any metal. SOLUTION: The purpose of this invention can be achieved by providing a dental prosthesis having at least one engaging member made of a plastic material with at least 10GPa bending elastic modulus and at least 0.8% maximum elongation percentage, preferably 10-80GPa bending elastic modulus and 0.8-4% maximum elongation percentage, before the material's plastic deformation occurs.
