MULTI-TAPER DENTAL ROOT CANAL FILLING POINTS/CONES AND PROCESS OF MAKING SAME

摘要

The present invention provides an improved root canal filling point/cone having a structure that can be manufactured precisely to result in better obturation with less micro-leakage. One aspect of the present invention is directed to a molded root canal filling point having progressively decreasing tapers from the smaller tip end to the larger end. Another aspect of the present invention is directed to a thermo-pressure molding process for manufacturing root canal filling appliances (e.g., Gutta Percha points). A further aspect of the present invention is directed to the structure of the mold for undertaking thermo-injection molding.

主权项

1. A cone for a dental root canal filling, comprising:
a body having a generally axisymmetric conical structure, wherein at least a section along the body has a tapered structure, and wherein the tapered structure has different tapers along the axial direction, varying progressively to define a multi-taper conical structure.
