The present disclosure provides a composite material, a method of making and using the composite material and dental products made by hardening the composite material. The composite material includes a polymerizable component, ceramic fibers and nanoclusters. Each of the ceramic fibers of the composite material has a length and where the length of fifty percent of the ceramic fibers, based on a total number of the ceramic fibers, is at least 50 micrometers and the length of ninety percent of the ceramic fibers, based on the total number of the ceramic fibers, is no greater than 500 micrometers. The composite material can also include discrete non-fumed metal oxide nanoparticles. The composite material can be hardened to become any one of a dental restorative, a dental adhesive, a dental mill blank, a dental cement, a dental prostheses, an orthodontic device, an orthodontic adhesive, a dental casting material or a dental coating.
本公开提供了一种复合材料、一种制造和使用该复合材料的方法以及通过硬化该复合材料制成的牙科产品。复合材料包括可聚合成分、陶瓷纤维和纳米团簇。复合材料的每根陶瓷纤维都有一定的长度,其中,根据陶瓷纤维的总数,百分之五十的陶瓷纤维的长度至少为 50 微米,而根据陶瓷纤维的总数,百分之九十的陶瓷纤维的长度不大于 500 微米。复合材料还可以包括离散的非气相金属氧化物纳米颗粒。复合材料硬化后可成为牙科修复体、牙科粘合剂、牙科磨坯、牙科粘合剂、牙科修复体、正畸装置、正畸粘合剂、牙科铸造材料或牙科涂层中的任何一种。
