Abstract: Dental matrix band devices including a housing with a band, a tensioning mechanism 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.

Abstract: A running form training device for training a runner to properly position and move their arms includes a harness, a pair of bands, and a pair of cuffs. The harness can be donned by a user so that the harness is removably engaged to a torso of the user. The bands are resiliently stretchable. Each band is engaged to the harness so that the band extends from proximate to a front of a respective shoulder of the user. Each cuff is engaged to a first end of a respective band and is removably engageable to a respective wrist of the user. The bands draw the arms of the user toward the harness, thereby restricting movement and positioning of the arms to promote proper running form.
