Title:
DENTAL COMPOSITE BLANK AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/262814
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a dental composite blank, comprising the steps of: (a) preparing a mixture by mixing a raw material including an unsaturated double bond compound, a filler, and a polymerization initiator; (b) preparing a composite paste in which the unsaturated double bond compound is uniformly dispersed among the filler by pressing the mixture; (c) injecting the composite paste into a mold; and (d) curing the composite paste injected into the mold. The dental composite blank and the method for manufacturing same of the present invention additionally comprise the step of applying high pressure in the step of mixing the dental composite paste, whereby monomers or oligomers uniformly permeate among the high content filler, thereby reducing the degree of non-uniformity in the paste, and accordingly there is an effect of improving mechanical properties of the dental composite blank.
