回顾了“激光钻”的发展历程,归纳总结了牙硬组织的光学性质及牙硬组织与激光的相互作用方式和机制,综述了激光在牙釉质、牙本质、牙结石和牙槽骨等硬组织上的应用研究动态和最新进展,并对其存在的问题及发展趋势进行了探讨。分析表明:硬组织激光消融技术在牙科存在广阔的应用前景。 The development history of “laser drilling” was reviewed. The optical properties of dental hard tissue and the mode and mechanism of interaction between dental hard tissue and laser were summarized. The effects of laser on enamel, dentin, calculus and alveolar bone And other hard-applied research trends and the latest developments, and its existing problems and development trends were discussed. Analysis shows that: hard tissue laser ablation technology in dentistry has broad application prospects.
