Posterior composite restoration instrument and method

A method and apparatus for restoration of teeth using light curable restoratives while assuring interproximal contact between the restored tooth and an adjacent tooth. The apparatus is in the form of a hand-held instrument with a specialized tip to hold an amount of pre-cured composite which is made from the same material as the restorative material or other compatible material and is intended for permanent placement in the tooth during the restorative process and becomes an integral part of the restoration. A tooth cavitation opening through a vertical tooth surface about which a matrix band has been tightened is filled by alternate deposition and curing of successive layers of the light curable restorative to a level at or below the plane of maximum circumference of the tooth. The amount of pre-cured composite is placed in a layer of uncured composite on this plane and the instrument is used to apply pressure to the amount of pre-cured composite to establish interproximal contact. This layer is cured, securing the amount of pre-cured composite and deforming the matrix band outwardly for subsequent filling and curing to complete the restoration.

APPLICATION TIP

Device for pushing away a dental element, and method for filling dental elements

Device for pushing away an enclosure arranged around a dental element. When filling dental elements, it is important that adjacent dental elements should come into contact with one another at a defined location. To this end, the invention proposes a tool for pushing the enclosure arranged around the dental element onto the adjacent dental element during the filling operation. In the vicinity of the free end, this tool is provided with a thickened section which has to push away an enclosure of this type. This thickened section is provided with a recess in the vicinity of the free end, approximately in the center. This recess forms an elevation in the filling material, and in this way shrinkage stresses can be guided out of the center of the filling material towards the outside, resulting in a shrinkage-free filling.
