Abstract

An oral scanning device can acquire scan data obtained by scanning a patient's oral cavity. The oral scanning device can acquire scan data obtained by scanning a patient's oral cavity. Before or after acquiring the scan data, or during the scanning process, the oral scanning device can load a checklist containing multiple items to be verified during the oral scanning process. Based on the scan data, the oral scanning device can determine whether each of the multiple items has been completed. The oral scanning device can display the completion status on the screen of a display device. If there are incomplete items, the oral scanning device can display the scan area corresponding to the incomplete items. The oral scanning device can acquire additional oral scan data for the scan area corresponding to the incomplete items.

Description

Method and apparatus for processing oral scan data based on a checklist According to one embodiment of the present specification, the invention relates to a checklist-based oral scan data processing method and apparatus. More specifically, the invention relates to a technology that manages a scan procedure based on a checklist to improve the accuracy and completeness of the scan during the process of scanning the inside of the oral cavity in three dimensions using a dental oral scanner, verifies in real-time whether each item is completed according to the scan data, and induces the user to perform a supplementary scan for incomplete items. Dental oral scanners are widely used as devices that digitize a patient's oral structure into a three-dimensional (3D) form, enabling precise analysis of tooth shape, occlusion status, and relationships between adjacent teeth. By digitally replacing the impression-taking process, these oral scanners reduce working time, minimize patient discomfort, and enable data-based diagnosis and treatment planning. However, due to the complex topographical structure of the oral cavity and various environmental factors such as gloss, saliva, and bleeding, data omission, distortion, or duplication are likely to occur during the scanning process. In particular, scan quality can vary significantly depending on the dentist's proficiency as well as the scanner's position, angle, and movement speed, which can lead to a decrease in the reliability of the scan data. Furthermore, if essential scan areas such as the occlusal surface, margin line, adjacent teeth, and opposing teeth are omitted, errors may occur during prosthetic fabrication or rescanning may be required, resulting in a decrease in overall treatment efficiency. Existing systems determined whether a scan was complete by simply analyzing the surface quality or area of the scanned data, and did not provide systematic guidance on which additional areas the user needed to scan. Furthermore, since feedback received from dental technicians was processed through a separate manual process after the scanned data was transmitted to an external feedback device or system, there was a lack of functionality to automatically incorporate such feedback to improve scan guides or checklists. Therefore, there is a need for checklist-based oral scan data processing technology capable of improving scan quality by checking the completion status of essential scan areas, data density, and occlusal accuracy in real time during the scanning process, and clearly notifying the user of incomplete items. Furthermore, a system is required to improve overall data quality and work efficiency by automatically updating the checklist based on natural language processing feedback and incorporating it into the subsequent scanning process.
