Dental composite blade

A dental composite blade comprising:

• a mounting portion for mounting the blade to a blade holder;
• a tool portion including
• (a) a proximal end and a distal end, and extending therebetween along a tool path defined within a transverse plane;
• and
• (b) a first lateral edge and a second lateral edge disposed on opposing sides of the transverse plane;
• a frontal plane defined orthogonally to the transverse plane;
• and
• a longitudinal axis defined at the intersection between the transverse plane and the frontal plane;
• wherein the mounting portion includes
• (a) a terminal section, a tool interface section and a securement section extending therebetween along the longitudinal axis, the securement section including an elongated mounting slot for receiving a blade retention element of the blade holder;
• and
• (b) one or more securement flaps attached to the securement portion for auxiliary engagement of the blade holder, the one or more securement flaps being disposed laterally of the longitudinal axis.

A dental composite blade comprising:

• a mounting portion for mounting the blade to a blade holder, and
• a tool portion including a proximal end and a distal end, and extending therebetween along an arc defined within a transverse plane, the tool portion further including
• (a) a proximal section adjacent the proximal end, a distal section adjacent the distal end, and an intermediate section between the proximal and distal sections;
• (b) a first lateral edge and a second lateral edge disposed on opposing sides of the transverse plane, the lateral edges each being convex at the proximal section with respect to the transverse plane, and concave at the intermediate section with respect to the transverse plane;
• and
• (c) an obverse face and a reverse face disposed oppositely of one another, each of which extends between the first and second lateral edges;
• wherein
• (a) a frontal plane is defined orthogonally to the transverse plane;
• (b) a longitudinal axis is defined at the intersection between the transverse plane and the frontal plane;
• (c) the mounting portion includes a terminal section, a tool interface section and a securement section extending therebetween along the longitudinal axis;
• and
• (d) the securement section includes an elongated mounting slot for receiving a blade retention element of the blade holder.
