Abstract
Dental matrix band devices including a housing with a band, a tensioning device for the band with the control for the tensioning mechanism controllable by a control knob external to the housing, and at least one deflector pushbutton. The deflector pushbutton(s) applies pressure on an upper or lower portion of the band causing the geometry of the band to change. The resulting band geometry forms a conical loop better matching the configuration of a tooth. In one embodiment two deflector pushbuttons are provided and positioned to apply pressure on the upper or lower portion of the band depending on which deflector pushbutton is depressed in the housing. In another embodiment a single deflector pushbutton unit is provided with a pushbutton at each end.
