Selective laser melting(SLM) technique represents a new direction in rapid prototyping technology, which enables the fabrication of precise metal parts without the limitation of complex shapes, sizes, and inner cavities. The technique possesses many advantages, such as high efficiency, high flexibility and high digitalization. With the rapid development of three-dimensional reconstruction and SLM technique, individualized diagnoses and treatments have become widely used in many branches of stomatology, including oral and maxillofacial surgery, dental prosthesis, dental implantation and orthodontics. A technology that simplifies manufacturing and operational procedures, as well as decreases accumulated errors during processing, will become a research hotspot in the near future.
