The embodiment of the invention provides a detection method and a detection device for matching precision of a tooth mold forming. The method comprises the following steps of obtaining inner contour data of the formed dental impression sheet and outer contour data of the tooth mold; determining the size of sampling values corresponding to the inner contour data of the formed dental impression sheet and the outer contour data of the tooth mold; by determining the size of the sampling values, fitting and aligning the inner contour data of the formed dental impression sheet and the outer contourdata of the tooth mold; reserving the data corresponding to the effective areas of the inner contour data of the formed dental impression sheet and the outer contour data of the tooth mold; fitting and aligning the data corresponding to the effective areas of the inner contour data of the formed dental impression sheet and the outer contour data of the tooth mold; analyzing the deviation of the effective areas after fitting and aligning, and detecting the matching precision between the tooth mold and a tooth retainer, a tooth corrector and the like according to the generated analysis data.
Description
technical field [0001] The invention relates to the technical field of dental mold forming, in particular to a method and a detection device for detecting matching accuracy of dental mold forming. Background technique [0002] Orthodontic appliances are dental instruments used to correct the position of teeth, and tooth retainers are dental instruments worn after orthodontics to maintain the position of teeth. After the orthodontic appliance and the tooth retainer are manufactured, they need to be tested for matching accuracy with the dental model to determine whether the orthodontic appliance or the tooth retainer can be properly worn on the teeth. [0003] In the existing detection method, when the matching accuracy of the tooth retainer or the orthodontic appliance and the dental model is tested, the thermoplastic molded dental impression is usually heated and softened, placed on the surface of the tooth retainer or the orthodontic appliance, and then given Positive or n...
