3Shape Ortho System
The .O3S file extension is primarily associated with 3Shape Ortho System, a software suite developed by 3Shape for orthodontic treatments. These files contain 3D scan data of a patient's dentition, typically generated by intraoral scanners. The data within .O3S files is used for diagnosis, treatment planning, and the creation of orthodontic appliances like clear aligners or retainers. The specific internal structure of .O3S files is proprietary to 3Shape and is not publicly documented. This file format is classified as 3D Scan Data.

O3S file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our analysis of the O3S files produces the following result:

The file type is very recent. The file name study.o3s is characteristic of these files. Files like these have the following tags: monte, and include person-related information.
