Abstract
Abstract A dental implant system and method for effecting a dental restoration using the same. The dental implant system having an implant fixture adapted to be deployed in a bone; an impression coping adapted to be selectively deployed on the implant fixture and in a dental impression; a laboratory analog adapted to be selectively deployed on the impression coping and in a dental cast; a spherical abutment adapted to be selectively deployed on the laboratory analog; and a multiaxis abutment adapted to be adjustably deployed on the spherical abutment; wherein the spherical abutment and the multiaxis abutment are used to generate a cast permanent abutment which may be received by the laboratory analog and the implant fixture.
