  • Publication number: 20210322135
    Abstract: Dental matrix bands with novel surface structures and use thereof in dental procedures are described herein. The matrix band features a three-dimensional surface structure that is contoured to an outer portion of a torus to allow the matrix band to securely fit around a tooth. The matrix band comprises: an outer surface of the matrix band; an upper and lower edge of the matrix band; a proximal and distal end of the matrix band; and a concave ridge disposed along the band. The outer surface of the band forms a first convex curve between the upper edge and the lower edge of the band and a second convex curve between the proximal and the distal end of the band. The concave ridge may extend between the upper edge and the lower edge of the band and between the proximal and distal ends of the band.

The band comprises: an outer surface of the band; an upper and lower edge of the band; a proximal and distal end of the band; and a flattened region disposed along the band. The outer surface of the band forms a first convex curve between the upper edge and the lower edge of the band and a second convex curve between the proximal and the distal end of the band. The flattened region can extend between the upper edge and the lower edge of the band and between the proximal and distal ends of the band.

  • Patent number: 10524878
    Abstract: A dental device for shaping matrix bands. The device has a first arm pivotally connected to a second arm. A male head component having a curved, convex inner sidewall with a flattened surface centrally disposed thereon is connected to a bar portion of the first arm. A female head component having a curved, concave inner sidewall with a flattened surface centrally disposed thereon is connected to a bar portion of the second arm. When a handle portion of the first arm is pivoted towards a handle portion of the second arm, the first bar portion pivots toward the second bar portion. The male head component mates with the female head component such that the inner sidewall of the male head component interfaces with the inner sidewall of the female head component, and the flattened surface of the male head component interfaces with the flattened surface of the female head component.

  • Patent number: 9949727
    Abstract: The present invention features an anti-rotation instrument system which could be used in all health professions including medical, dental, and any other specialties. The system includes an anti-rotation instrument device featuring a main handle, a first removable hand grip and a first instrumental tip. The first removable hand grip is attached to a first female screw cavity located on the main handle. One end of the instrumental tip passes through a channel located within first hand grip with an anti-rotation key located on the instrumental tip securely residing within a dent located on a distal end of the first removable hand grip having threading located on an end of the instrumental tip that is subsequently screwed into a first female screw cavity of the main handle such that the first hand grip is tightly sandwiched between the first instrumental tip and main body.
