摘要/Abstract

摘要： 口腔树脂作为重要的牙色充填材料,自面市以来一直广泛应用于临床。近红外光(near infrared, NIR)较可见光具有更高的穿透性,且特定波长NIR光照射上转换材料(upconversion, UC)可激发出不同波长的可见光,如蓝光,进而光照固化光固化型树脂。近年来,基于这些特性,提出了将UC材料掺入光固化型树脂中,经NIR光照射达树脂深层,再激发深层树脂中的UC材料转换为光固化所需的蓝光,实现口腔树脂深层固化的可能性。本文就其研究现状、存在问题及远期发展做一论述。

Abstract: As an important dental filling material, resin has been widely used in clinic since its development. Near infrared (NIR) light has a higher penetrability than visible light, and the upconversion (UC) material irradiated by NIR light with a specific wavelength can excite different wavelengths of visible light, such as blue light, and then light cure the dental resin. In recent years, based on these characteristics, it is proposed that UC materials could be incorporated into the UV curable resin. The UC material was then irradiated by NIR light and excited UC materials in the deep layer to convert into the blue light required for UV curable resin. This was called the deep curing of the dental resin. In this paper, the related research, existing problems, and possible long-term development of this modified method are discussed.
