Claim 5:
6. The data-based intelligent method for selecting the intraoral prosthesis design scheme according to claim 1, further comprising a sorting method of the intraoral prosthesis design second theme code in the second recommendation list as follows:
(1) sorting based on partially edentulous jaw information of a patient;
performing sorting according to an ascending order of distance function values of the first code of partially edentulous jaw information; to be specific, a smaller distance function value indicates a higher sorting location of the intraoral prosthesis design second theme code corresponding to the first code of partially edentulous jaw information; wherein
for any two pieces of different first code of partially edentulous jaw information, a case in which the two pieces of different first code of partially edentulous jaw information correspond to identical second code of partially edentulous jaw information exists; in this case, a calculation method of a distance function between the two pieces of different first code of partially edentulous jaw information is as follows:, D

wherein the dentition second location code of first code of partially edentulous jaw information is a1a2 . . . ai, and the dentition second location code of second first code of partially edentulous jaw information is b1b2 . . . bi, 1≤i≤16;
sorting is performed according to the other dentition information code, and the other dentition information code comprises a tooth loosening degree coefficient and a tooth rotation matrix; and
(2) custom sorting based on subjective and objective scoring results;
experts subjectively score design themes from dimensions of hygiene, mechanical balance, and aesthetics; at the same time, finite element calculation and in vitro mechanical verification are introduced to objectively score the design themes to obtain subjective and objective scoring results, and the subjective and objective scoring results provide a basis for user-defined theme sorting.
