A dental restoration system including a dental prosthesis having an occlusal body having defined therein a cavity and having an outer profile； and a dental abutment having a main body with a gingival part for anchoring to an implant and an occlusal part shaped to fit within the cavity to support cementation of the dental prosthesis, wherein the occlusal part of the main body has an outer profile radially closer to the longitudinal center axis than an outer profile of the gingival part at the interface between the occlusal part and the gingival part, thereby defining a shoulder between the occlusal part and the gingival part. The radial width of the outer profile of the dental prosthesis where it meets the shoulder is the same as or smaller than the radial width of the outer profile of the gingival part at the shoulder.
