A dental prosthesis securing system (100) secures a dental prosthesisto a dental implant (110). An abutment for cement (130) has a base surface (138) for placement against the dental implant (110). The base surface (138) does not define an engagement shape that requires alignment with a complementary shape defined by the implant. A securing mechanism (250) secures the abutment for cement (130) to the dental implant (110).
