ABSTRACT:
A device is disclosed for applying and holding a dental matrix strip against the side of a tooth which is to be filled. An embodiment of the device comprises a split ring that slidably receives a matrix. The split ring in this embodiment can have cushions on its ends sized to resist passage through matrix apertures following insertion of such cushions through these apertures when these components are slidably coupled together. This embodiment can also comprise respective matrix slots that receive portions of the split ring to at least partially conform the shape of the matrix to the shape of the split ring.
