Abstract
A flexible frame supports and at least partially surrounds a thin polymer sheet. The frame and polymer sheet is positioned between a tooth being filled and an adjacent tooth so as to extend partly or completely around the buccal and lingual sides of the tooth being filled. The frame may be severable to facilitate removal of the frame and apparatus following the completion of a filling. A mechanism may be included for tightening the gingival border of the frame to more closely follow the natural tooth contour. A mechanism may also be included for tightening the occlusal border of the frame with such tightening mechanisms being independently operated. The frame may be secured to a tooth being treated such as utilizing adhesive tabs.
