A prosthesis that contains zirconia and supplements a defective portion of a natural bone, and that is changed to a color approximate to that of the natural bone by a heat treatment after a γ-ray sterilization treatment. The color approximate to that of the natural bone has an L* value of 60 to 90, an a* value of −5 to 10, and a b* value of −5 to 10 in the L*a*b* color space. The highest temperature in the heat treatment is 100° C. to 300° C. The prosthesis is a fixture of a dental implant embedded into and bonded to a natural bone, an abutment, an implant crown, and the like.

A denture lock is disclosed, comprising a tubular bushing extending between a distal end and a proximal end. The denture lock is configured with a bore accommodating a locking pin displaceable between a locked position at which the locking pin projects from the distal end of the bushing, and an unlocked position at which the locking pin is at least partially retracted. At least an external surface portion of the bushing is configured with a coupling arrangement for removably securing a denture therewithin.
