A packaged unit of composite for performing an aesthetic restoration. The unit is mounted on a polymeric film carrier material and is covered and sealed with the same or otherwise suitable covering film. The carrier film may be an elongated strip containing serially placed units of composite, each readily separable from the strip for individual usage. This packaging is in light restrictive outer packaging since the preferred unit of composite is of a light-cured material such as bis-GMA. In preferred packaging, the unit dose is singular and applicable to the tooth surface with the film carrier which is adapted with tabs to facilitate handling and the draping or damming of the subject tooth from adjacent teeth to facilitate application of the composite. The composite is then worked, i.e., formed on the tooth with the film intermediate the composite and the customary forming tools. In preferred embodiments, the single unit packaging of composite is mounted on a clear carrier film which includes embrasure tabs for selective insertion in the embrasure between the teeth, and in a further preferred embodiment, the carrier film includes an incisal tab to cover the incisal edge of the tooth. The clear carrier is contained in further outer packaging which limits actinic radiation from reaching the composite.

Interproximal matrix with elastomeric wedge
A dental apparatus adapted to facilitate formation of a filling in an object tooth and to retain the filling within normal boundaries of the object tooth and generally spaced from an adjacent tooth includes a matrix having a resilient wedge member attached thereto. The resilient wedge member is elongated and has enlargements at opposite ends thereof. In use, the resilient wedge member is stretched. While the resilient wedge member is in the stretched state, the matrix and resilient wedge member are placed together between the object tooth and an adjacent tooth. The resilient wedge member is then released and contracts toward its natural unstretched state. As the resilient wedge member contracts, it urges the matrix to surroundingly conform to the object tooth. In this way, a tooth is comfortably and conveniently prepared to receive a filling.

Methods and Devices for Fixed Dental Restoration
This invention relates to methods and devices for restoring teeth using fixed restorations. In particular, the invention provides a system, kit, and devices for the management of interproximal areas for traditional cementation and / or bonding of dental crowns, onlays, inlays, veneers and bridges. In the method, a barrier is positioned in contact with the tooth being restored and an adjacent tooth to cover a section of the tooth being restored and to create separation of the tooth being restored and the adjacent tooth. Cement is applied to the first mating surface of the fixed restoration and / or to the second mating surface of the tooth, and the first mating surface of the fixed restoration and the second mating surface of the tooth are positioned adjacent each other to seat the fixed restoration on the tooth. The barrier covers a section of the tooth being restored to prevent cement from bonding to the section of the tooth. This eliminates the need to remove hardened cement from this section of the tooth.

Anterior composite matrix dental restoration system
The anterior composite matrix dental restoration system provides a matrix for holding a composite filling material in place as it cures, and a tool for holding the matrix in place during the curing of the filling material. The matrix comprises a thin, flat, flexible, and transparent sheet of plastic material with parallel tubular extensions on the opposite ends. The distal ends of the specialized forceps tool are inserted into the tubular ends of the matrix and used to install, hold, and remove the matrix. The relatively small and narrow tool greatly increases the comfort of both patient and dentist or dental technician by precluding need to insert and hold the fingers in the mouth of the patient to install, hold, and remove the matrix. The matrices may be provided in different sizes, with at least the tubular end components being optionally color coded to indicate the corresponding size.
