Non-interruption scanning method for multi-tooth-position intraoral three-dimensional scanning

The invention relates to a non-interruption scanning method for multi-tooth-position intraoral three-dimensional scanning, which comprises the following steps of: scanning an occlusal surface part of a dentition from one side of the dentition to the other side of the dentition one by one to obtain data Do above a high point line of the occlusal surface and cheek-lingual surface appearance of each tooth; respectively scanning the buccal side surface and the lingual side surface of the dentition according to the same tooth position sequence, if two adjacent images cannot be spliced at a certain time node, splicing the latest three-dimensional image at the time node to the Do by taking buccal surface data or lingual surface data in the Do as a common region, and obtaining buccal surface data Db and lingual surface data D1 of the dentition without pausing the scanning operation; respectively registering the Db and the D1 with the Do, and supplementing scanning Dc for individual areas; and integrally fusing the Do
