Dental crowns are divided into partial crowns and full crowns. Some crowns are divided into 3/4 crown, half crown, open crown and 7/8 crown according to the different tooth tissues covered. Whether it is a partial crown or a full crown, the manufacturing method is restoration.

Open crown is a medical term published in 1992. All-ceramic crown is a 360-degree-wrapped prosthesis, and porcelain veneer is a labial prosthesis.
