Abstract: Devices, methods, and systems for the design, fabrication, modification, and implantation of dental prostheses. An implant is created that has a shape closely or precisely conforming to the natural shape of a modified or unmodified tooth socket. The implant is used to anchor any of a variety of dental restorations or other substitute devices to bone. Further, methods, systems, and apparatuses for taking radiographs at specific, standard, and/or reproducible angles. A first radiograph is taken, using an aiming apparatus, with the aiming direction forming a first angle with the normal to an image plane of an image receptor. At least one additional radiograph is taken, using the aiming apparatus, at a different aiming direction from the first direction. Radiographs taken with the multiple aiming angles are used to create a three-dimensional image of an object represented by the radiographs.

Abstract: The present disclosed subject matter relates to methods and compositions for restoring a diseased or damaged tooth such that infection is inhibited or eliminated and pulp regeneration is facilitated. The disclosed subject matter also includes a composition comprising a physiologically acceptable matrix seeded with pulp cells. The matrix can be capable of being injected into the pulp chamber of a tooth. In some embodiments, the matrix of a composition includes a hydrogel (e.g., collagen, chitosan, alginate, MATRIGEL™, gelatin, JELL-O®, fibrin), a mesh (e.g., polylactide-coglycolide (PLGA) mesh, polylactide (PLA) mesh, or polyglycolide (PGA) mesh, a cross-linked fiber mesh, a nanofiber mesh, a mesh fabric, biodegradable polymer mesh), a microsphere (biodegradable polymer microsphere, a hydrogel microsphere), or a combination of any of the foregoing. In yet other embodiments, the matrix includes a nanofiber, an artificial three-dimensional scaffold material, or a synthetic three-dimensional scaffold material.
