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.
