Abutment posts, gingival collars, and universal adaptors along with their fixation screws that are used for insertion into dental implants are revealed. The universal adaptor has at one end an external hexagon post, cylindrical post, or other means of varying dimensions of such a nature as to fit into several different types of manufactured implants with various dimensions and internal thread diameters. The adaptor is universal in that it matches to many different shaped, sized, and styled implants, and standardizes their restoration with uniform gingival collars and abutment posts. A small flange which tapers from the dimension that matches the individual underlying implant to a standardized size at its free end. An external post, octagon in shape, extends from the flange towards the free end. A gingival collar of varying sizes, which extends from the top of the flange to the height of the gingival tissue, is used to bring the restoration of the implant into the oral cavity. It tapers from the open end at the flange of the universal adaptor to a larger standardized size in order to more naturally represent the size and shape of a natural tooth root. It has an internal sleeve, extending from the open end at the adaptor to the free end at the abutment insertion which has an octagon shape to receive the octagon posts of the "adaptor" and the abutment post. In some instances, the abutment post has at one end an external octagon post to be inserted into the gingival collar. It may be designed in a variety of angulations to upright an otherwise angulated implant that is not parallel to other teeth or implants. The post tapers from the gingival collar at the open end to its free end and has at its free end one or more sockets to receive fixation screws to affix the abutment post to the universal adaptor and to affix a fabricated crown or coping that has a flaring section at its open end. The crown may be affixed to the post either by cementing it on to the abutment post or by screwing it into the socket in the post.
