Claim 3:
4. The data-based intelligent method for selecting the intraoral prosthesis design scheme according to claim 1, wherein the other dentition information code is other teeth information obtained based on the one piece of first code of partially edentulous jaw information, comprising:
(1) a tooth loosening degree coefficient: for a tooth with code of 1, if code of a tooth on either side or both sides of the tooth is 0, the tooth is defined as an alternative abutment tooth, and a loosening degree coefficient of the tooth is obtained; for a tooth with code of 1, if code of teeth on both sides of the tooth is 1, the tooth is defined as a general abutment tooth, and a loosening degree coefficient of the tooth is obtained; and the loosening degree coefficient is any decimal between 0 and 1, and a smaller number represents a more severe tooth loosening degree; and
(2) a tooth rotation matrix: for a tooth with code of 1, a three-dimensional rotation matrix Mt is defined to reflect a relationship between an actual space state and a standard healthy state of the tooth, wherein the subscript t is the dentition first location code.
