Abstract
The present invention relates to a method of manufacturing a dental composite blank, including (a) placing a composite paste in a mold, (b) pressurizing the composite paste placed in the mold at a first pressure (P), (c) pressurizing the composite paste placed in the mold at a second pressure (P), and (d) curing the pressurized composite paste, in which each of steps (b) and (c) is performed once or multiple times, and the first pressure (P) is less than or greater than the second pressure (P). The dental composite blank and the method of manufacturing the same are effective at dispersing a non-dispersed filler and removing bubbles, thus improving mechanical properties, through repeated pressurization at different pressures before curing the composite paste.
