Disposable dental matrix retainer clamp |
摘要 |
A dental matrix retainer package includes a plastic matrix retainer clamp which permits a matrix band to be unlocked from its tightened position over a tooth without releasing the matrix band from the clamp entirely, permits a matrix band to be swiveled to accommodate different mouth quadrants with removal for reorientation, permits rapid retraction of a matrix band from a tooth, and permits careful tightening of a matrix band over a tooth in order to avoid the possibility of overtightening. The package is designed so that it must be entirely disposed of after use on a patient, thereby providing maximum assurance against cross contamination.
