A method of forming a dental composite includes photopolymerizing a dental composition. The dental composition includes a free-radically polymerizable (meth)acrylate resin, 75 percent by weight or greater of filler particles, and about 0.005 percent to about 5 percent by weight of at least one polymerizable stable radical. The photopolymerizing forms the dental composite such that the dental composite has a flexural modulus of about 9500 MPa or greater and the polymerizable stable radical reduces shrinkage stress of the dental composite caused by the photopolymerizing by 10% or greater. A method of forming a dental composite composition includes combining a free-radically polymerizable (meth)acrylate resin, 75 percent by weight or greater of filler particles, and about 0.005 percent to about 5 percent by weight of at least one polymerizable stable radical to form the dental composite composition.
形成牙科复合材料的方法包括对牙科组合物进行光聚合。牙科组合物包括可自由基聚合的(甲基)
丙烯酸酯
树脂、75%(按重量计)或更多的填料颗粒,以及约 0.005%至约 5%(按重量计)的至少一种可聚合的稳定基。光聚合形成牙科复合材料,使牙科复合材料具有约 9500 兆帕或更大的弯曲模量,可聚合稳定基使光聚合引起的牙科复合材料收缩应力降低 10%或更大。形成牙科复合材料组合物的方法包括将可自由基聚合的(甲基)
丙烯酸酯
树脂、75%(重量)或更多的填料颗粒和约 0.005%至约 5%(重量)的至少一种可聚合稳定基组合在一起,形成牙科复合材料组合物。
