  • Fabricating method of resin base denture
    Patent number: 4971735
    Abstract: A method of fabricating a resin base denture. The method includes: burying a wax denture in an investment in a tubular flask; removing the wax of the wax denture to form a hollow space; filling the space with resin; immersing the flask in water; and polymerizing the resin by microwave irradiation; thereby fabricating a resin base denture. When immersing the flask filled with resin in water, the lids are detected from the flask so that the investment is in direct contact with water.
