Artificial dental root having function of natural dental root
An artificial dental root having the function of a natural dental root is characterized in that the artificial dental root is made a shape-memorizing alloy capable of changing the apex morphology of the artificial dental root after implantation so as to stay in the jawbone. The artificial dental root is implanted in an alveolus and the apexes thereof then closely contact the inner surface of the alveolus owing to the shape-memorizing effect thereof to fix the dental root firmly in the alveolus.
