Abstract: A prefabricated, hybrid dental pulp organ replacement system has a tube-like core device formed as a substantially cylindrical sleeve formed of a high-strength, high-density material, having a coronal end and an apical end and configured to be partially inserted and fixed at its apical end to a root cavity. The system also has a root device forming a low-density, low-strength volume, including an apical portion formed in an inner volume of a root cavity of a tooth under restoration and a coronal portion extending slightly above a cement-enamel junction of the tooth. The high density core component redirects mechanical forces imposed thereon into a root periphery of a tooth to prevent the forces away from an axial center of the root while protecting the portion of the low density volume surrounded by the jacket from deleterious forces and fluids.

Abstract: A dental core and post system for restoration of teeth includes a core device and a dental post formed as a rod-like member extending along a central vertical axis between a coronal end and an apical end. At least one portion of the rod-like member including the apical end is configured for fixation within a root canal of a tooth for restoration. The core device is attached to or is integral with the coronal end of the dental post. At least one of the core device and dental post include an inner, low-density volume configured to limit mechanical forces communicated through the core device and dental post coaxially with the central vertical post axis after fixation.
