[Application of digital technique in shaping of emergence profile for prostheses supported by dental implant].

In the field of dental implantology, the design of interface esthetics not only affects the esthetic coutcome, but also affects the health and long-term stability of the tissue around dental implant. Dental implant, bone tissue, soft tissue, and prostheses' morphology are the four critical elements of interface esthetics. The emergence profile located at the junction of these four components is an important form of oral esthetics. With the wide application of digital technique in the field of dentistry, the shaping of emergence profile also involves the application of many kinds of digital approaches. This article intends to make a review of the application of digital technique in rehabilitation of interface esthetics to provide a reference for clinical practic.
