    摘要： A custom tool for forming a dental restoration in a mouth of a patient includes a first mold body providing for a customized fit with at least one tooth of the patient. The first mold body includes a portion corresponding with at least a first surface of the tooth and an interproximal portion corresponding with an interproximal surface of the tooth, the interproximal portion being of unitary construction. The first mold body is configured to combine with the tooth of the patient to form a mold cavity encompassing a first portion of missing tooth structure of the tooth.

    摘要： 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.

    摘要： A circumferential matrix system having a matrix band and a body, such that the body comprises a handle, a housing and a base, and a spindle within the body is attached to the handle. The matrix band on one end is permanently affixed to the spindle and the matrix band on another end is permanently affixed to an inside wall of the housing. The circumferential matrix system can be tightened around a tooth without the need or use of a retaining ring.

    摘要： A dental matrix band includes a band having a first end and a second end. The band is folded over with the first end and second end generally aligned. A portion of the band adjacent the first and second ends form opposed facing band portions in contact with one another, and another portion of the band forming a looped band forming a circumference. A first or stationary toggle is secured to the band at the first and second ends with the first toggle stationary with respect to the band. A second or movable toggle is formed over the band and is capable of sliding over the opposed facing band portions in contact with one another, whereby sliding of the movable toggle away from the first and second ends causes the circumference of the looped band to reduce in size.
