Abstract
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 filing appliances (e.g., Gutta Percha points). Another aspect of the present invention is directed to the structure of the mold for undertaking thermo-injection molding. A further aspect of the present invention is directed to a production line comprising the thermo-injection process.
