1. A data-based intelligent method for selecting an intraoral prosthesis design scheme, comprising the following steps:
step S1: establishing an intraoral prosthesis design scheme database based on predetermined data of partially edentulous jaw, wherein the database provides two data search paths comprising a first search for data of partially edentulous jaw and a second search for data of partially edentulous jaw;
step S2: acquiring data of partially edentulous jaw of a dentition by using a scanning device, and performing encoding on the data of partially edentulous jaw of the dentition to obtain one group of dentition information first code, wherein the dentition information first code comprises: first code of partially edentulous jaw information, dentition first location code, and other dentition information code;
performing data block division on the first code of partially edentulous jaw information to obtain second code of partially edentulous jaw information; and
calculating a data block center location of the second code of partially edentulous jaw information to obtain dentition second location code;
wherein one group of the first code of partially edentulous jaw information corresponds to one group of the second code of partially edentulous jaw information, and one group of the second code of partially edentulous jaw information corresponds to a plurality of groups of the first code of partially edentulous jaw information;
step S3: comprising a plurality of groups of intraoral prosthesis component information in the intraoral prosthesis design scheme database, wherein the intraoral prosthesis component information comprises: an intraoral prosthesis component type sequence and intraoral prosthesis component location code;
wherein the intraoral prosthesis component type sequence is a sequence formed for an intraoral prosthesis component type according to the dentition first location code in the step S2; and
the intraoral prosthesis component location code comprises: intraoral prosthesis component first location code and intraoral prosthesis component second location code, wherein the intraoral prosthesis component first location code is consistent with the dentition first location code, and the intraoral prosthesis component second location code is consistent with the dentition second location code;
step S4: obtaining intraoral prosthesis design theme code according to the first code of partially edentulous jaw information in the step S2 and the intraoral prosthesis component information in the step S3, wherein the intraoral prosthesis design theme code comprises: intraoral prosthesis design first theme code and intraoral prosthesis design second theme code;
wherein the intraoral prosthesis design first theme code is a combination of a plurality of groups of first matched intraoral prosthesis component information, and the first matched intraoral prosthesis component information provides complete consistency in both the intraoral prosthesis component type sequence and the intraoral prosthesis component location code; and
the intraoral prosthesis design second theme code is a combination of a plurality of groups of second matched intraoral prosthesis component information, and the second matched intraoral prosthesis component information provides complete consistency in the intraoral prosthesis component type sequence but inconsistency in the intraoral prosthesis component location code;
step S5: providing two different recommendation lists of intraoral prosthesis design schemes according to different intraoral prosthesis design concepts, specifically as follows:
step S5-1: in all intraoral prosthesis design first theme code obtained in the step S4, obtaining m pieces of intraoral prosthesis design first theme code based on one piece of first code of partially edentulous jaw information, and obtaining a first recommendation list comprising the m pieces of intraoral prosthesis design first theme code; and
step S5-2: calculating to obtain n pieces of first code of partially edentulous jaw information with smallest distance function values in all intraoral prosthesis design second theme code obtained in the step S4, wherein m pieces of intraoral prosthesis design first theme code are obtained based on one piece of first code of partially edentulous jaw information, one piece of intraoral prosthesis design first theme code corresponds to one piece of intraoral prosthesis design second theme code, and obtaining a second recommendation list comprising k pieces of intraoral prosthesis design second theme code; wherein k≤n×m;
a default format of the first code of partially edentulous jaw information comprises 1 letter and 16 digits, and each of the 16 digits is either 0 or 1; the data block division dividing all adjacent and successive identical code into one data block based on one piece of first code of partially edentulous jaw information; wherein all adjacent and successive “0”s are divided into one “0” data block, and after each alternative abutment tooth is excluded, all adjacent and successive “1”s are divided into one “1” data block; in the first code of partially edentulous jaw information, if code of one tooth is 1, and code of a tooth on either side or both sides of the tooth is 0, the tooth is an alternative abutment tooth;
the calculating of the data block center location performs separate calculations of a center location of each “0” data block and a center location of each “1” data block, wherein an average value is calculated for first location code inside a dentition region corresponding to each “0” data block or each “1” data block; and
step S6: displaying a plurality of intraoral prosthesis design schemes of different design themes in a three-dimensional manner, and producing a selected intraoral prosthesis design scheme from the plurality of intraoral prosthesis design schemes.
