The dental material contains a polymerizable dental resin of index of refraction n1, inorganic nano-scale solid particles of index of refraction n2, dental glass particles of index of refraction n3, and accessory substances to autopolymerize and light-cure the dental resin. The dental material exhibits a composite index of refraction n4 in the range of 1.56 to 1.70. The dental material imparts optimal esthetics to the tooth being restored and allows for application in substantially thick layers.一種牙齒材料，包含：一可聚合之牙齒樹脂，其折射指數n1，奈米級的無機固體粒子，其折射指數n2，牙齒玻璃粒子，其折射指數n3，用於使牙齒樹脂自動聚合或光硬化的輔助料，其中：該牙齒材料整體具有一折射指數n4，在1.56~1.70範圍，且該硬化的牙齒材料的折射指數在1.56~1.70範圍。此牙齒材料給予所要修復的牙齒最佳的光學性質，且亦可以厚的層厚度施覆。
