The present invention provides an improved root canal filling point/cone 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/cone. 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). Another aspect of the present invention is directed to the structure of the mold (40, 42) for undertaking thermo-injection molding. A further aspect of the present invention is directed to a production line comprising the thermo-injection process.
