Abstract: A dental impression tray and bite registration rim assembly comprises an impression tray, a handle and a bite registration rim. The handle and the bite registration rim are both detachably attachable to the impression tray. The connection elements between the handle and the bite registration rim to the impression tray may be the same or different. The handle is attached to the impression tray to facilitate taking of a precise gum impression, but is detached and replaced by the bite registration rim when taking a bite registration. Thus, a precise gum and bite registration may be conveniently taken in a single visit of the patient.

Abstract: A double matrix band and technique for using the same is utilized in tooth repair to minimize interproximal spacing. The first portion of the matrix band is wrapped around the tooth adjacent to that being repaired, and the second portion of the band is then wrapped around the tooth to be repaired. Light permeable materials may be used for the matrix bands, thereby allowing tooth repair with light curable materials.
