Abstract: A method of producing a working model for preparation of a clinical crown for attachment to an implant fixture in the mouth of a patient is described in which a laboratory analog, on which the crown is mounted during preparation, is formed as an assembly including a fixed sleeve and a detachable pin and wherein the crown-receiving portion of the pin element of the assembly replicates the crown-receiving portion of the implant fixture. The analog sleeve is fixedly mounted in a base segment of the model so that the analog pin bearing a crown to be prepared threadedly connected thereto can be removed from and returned to mounted installation in the model by simple sliding movement between the pin and sleeve. Also described is the resultant working model construction and the particular analog elements which also form parts of the invention.

Abstract: 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.

Abstract: The invention provides a method for dental restoration including direct modification or customization of a final abutment inside the patient's mouth. The final abutment is made from a non-titanium material. The final abutment, after being completely modified or customized, may then be used to support a crown. The invention exhibits numerous merits such as simplified procedure, cost-effectiveness, reduction of laboratory adjustment, reduction of chair time, and reduction of dentist office visits.

Abstract: Taking a digital implant or abutment level digital impression by means of intra-oral, computed tomography or other imaging method provides the restorative doctor and laboratory accurate and effective data for determining the implant position, angulation and locking feature orientation without a physical impression. Such data is correlated with a digital library to produce an output which enables design and fabrication of an accurate restorative device such as a prosthetic tooth or crown. In this way the time-consuming, costly and error prone mechanical replication of the relevant dental anatomy is obviated.
