ABSTRACT:
A dental matrix retainer in the form of a longitudinally split band having separate band portions for looping about the axially inner or gingival contour of a tooth and about the axially outer or cusp contour of the tooth. The two adjacent band portions have opposed notches in alignment along adjacent edges thereof for cooperating to define a singular aperture through which filling material may protrude into contact with an adjacent tooth, whereby the two band portions can be transversely separated and removed longitudinally from between the teeth after a cavity is filled without disturbing the contact.
