The invention provides a dentition movement track indicator and a tracing method. The device includes an intra-oral fixation assembly and an extra-oral movement indicating assembly, wherein the intra-oral fixation assembly includes a lower denture base, a left side retention steel wire, a right side retention steel wire and a positioning steel wire. The lower denture base is arranged on the lingual side of the lower dentition and respectively extends from a lower incisor to the far center of the last tooth on the left side and the right side and clings to the lingual mucous membrane. The left side retention steel wire and the right side retention steel wire are distributed in a left-right symmetry mode. The extra-oral movement indicating assembly includes a connecting rod, an arc rod, an indicating plate and a plurality of rectangular parallelepiped thin rods. According to the dentition movement track indicator, an intra-oral fixation assembly.

Abrégé

A dentition motion trajectory indicator and a tracing method. The device comprises an intra-oral fixation assembly and an extra-oral motion marking assembly; the intra-oral fixation assembly comprises a lower dentition base support (15), a left-side retention steel wire (1), a right-side retention steel wire (2), and a positioning steel wire (3); the lower dentition base support (15) is provided on the lingual side of a lower dentition and respectively extends from mandibular incisors to the distal of the last teeth on the left and right sides and clings to lingual mucosa; the left-side retention steel wire (1) and the right-side retention steel wire (2) are symmetrically distributed left and right; the extra-oral motion marking assembly comprises connecting rods (8), an arc-shaped rod (9), an indicator plate, and a plurality of straight cuboid thin rods (12). The dentition motion trajectory indicator uses a personalized intra-oral fixation assembly that is adapted to an individual dentition condition and does not cover an occlusal surface of a maxillary dentition and a mandibular dentition. Therefore, when dentition motion is collected, the occlusal surface of the upper and lower dentitions can be in direct contact, no vertical gap exists between the upper and lower dentitions, and the motion process of the dentition is accurately transferred, without affecting tracing of motion trajectory.
