ABSTRACT:
An appliance is provided which can safely and securely carry one or more inserts into the cavity to be filled, apply a constant positive pressure against an adjacent tooth, and allow the dentist to adjust the location and spacing of the insert(s) and the amount of pressure exerted by the proximal insert against the adjacent tooth, as desired. Following initial placement of the insert, the insert is secured in a desired position and maintained in that position during the entire filling process so that both of the practitioner's hands are free to carry out the polymer delivery and polymerization process.
