A dental assembly includes an implant having a tubular body portion which can be positively secured within a bore in a jawbone by an expander mechanism, and a two-piece abutment secured to the implant and having a collar which is incapable of rotation with respect thereto. In a related process for preparing a tooth prosthesis, a transfer sleeve is utilized in a process to replicate conditions in the mouth, including the configuration of the abutment assembly, in manufacturing a custom analog. A custom analog is cast into a stone mold to provide an exact duplicate of the mouth. From this stone mold a crown can be manufactured in a laboratory to precisely fit in the user's mouth over a customized abutment. A treatment crown sleeve may be utilized in connection with a provisional tooth.
