Detailed Description

The invention is further described with reference to the drawings and the detailed description.

Certain directional terms used hereinafter to describe the drawings, such as "inner", "outer", "above", "below", and other directional terms, will be understood to have their normal meaning and refer to those directions as they normally relate to when viewing the drawings. Unless otherwise indicated, the directional terms described herein are generally in accordance with conventional directions as understood by those skilled in the art.

The terms "first," "second," and the like as used herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

Referring to fig. 1-2, an intraoral fixation device 100 for testing the change of mechanical properties of an elastic ligature ring 200, the intraoral fixation device 100 includes a pressed film holder 1, the pressed film holder 1 includes a plurality of accommodating cavities 11 arranged in sequence, the teeth of a tested person are respectively embedded into the accommodating cavities 11, the inner wall of the accommodating cavities 11 is attached to the surfaces of the teeth of the tested person, in this embodiment, the pressed film holder 1 is a transparent hard glue holder.
