The BPD is an improved design for a universal plastic pattern.
The simple to use plastic dovetail intracoronal attachment can be used for:
The built in mandrel on the male and female provides the convenience of using the BPD in a traditional manner, or inverting it.
By inverting the BPD,
The patterns are produced in a clean burnout plastic. The reduced size provides wider application, better abutment contours, and improved esthetics. Taper ensures easy insertion and well defined proximal plates provide increased stability. A universal attachment.
Steps 1 – 11 are the same as in the Traditional Bridgework technique.
