Butterfly-shaped dental matrix band

Abstract

Described are various embodiments of a butterfly-shaped dental matrix band for performing fillings on two adjacent teeth simultaneously. In one embodiment, the band comprises a central portion, the central portion resting at the contact point upon the band being engaged in-between the adjacent teeth; two thin and pliable adjacent wings, each wing surrounding and extending away circumferentially from an edge of the central portion, and wherein a first portion of each wing comprising an area extending from said central portion to a lower edge of each wing along said vertical axis has a thickness equal to at most half the thickness of the central portion; and a second portion of each wing not included in said first portion has a thickness equal to the thickness of the central portion. In some embodiments, each wing has a tab at the upper edge thereof to grab and manipulate the matrix band.
