Abstract

The invention relates to a mandibular three-dimensional movement path tracking device used for a virtual articulator. The mandibular three-dimensional movement path tracking device comprises a maxillary retention clamp plate, a first connecting rod, a first shooting target connecting rod, a first shooting target, a mandibular retention clamp plate, a second connecting rod, a second shooting target connecting rod, a second shooting target, a left camera, a right camera and a fixing plate; the maxillary retention clamp plate is connected with the first connecting rod, and the first shooting target connecting rod is connected with the first connecting rod and the first shooting target; the mandibular retetion clamp plate is connected with the second connecting rod, and the second shooting target connecting rod is connected with the second connecting rod and the second shooting target; the left camera and the right camera are installed on the fixing plate, and the fixing plate is erected right ahead of the first shooting target and the second shooting target. The tracking device can fast obtain the mandibular three-dimensional movement path of an individual, output path data can be directly input into open type oral cavity restoration CAD software, and therefore the design and manufacturing quality and clinic adaptability of the crown and bridge occlusal surface are improved.

Description

technical field [0001] The invention relates to a mandibular three-dimensional movement track tracking device, in particular to a mandibular three-dimensional movement track tracking device for a virtual (occlusal) frame. Background technique [0002] Data of mandibular movement path (data of mandibular movement path) refers to the points, curves or key parameters that constitute the trajectory of bilateral condyles, mandibular dentition, or the whole mandibular relative to the upper jaw during mandibular movement, such as condylar tract, incisor Road slope etc. It is an important basic data for the research, diagnosis and digital design of the functional occlusal surface of oral restorations in digital stomatology. [0003] Humans have been studying mandibular motion data acquisition for a long time. Before the introduction of 3D digital technology, mandibular motion was decomposed into the motion of bilateral condyle, mandibular central incisor and other anatomical landma...
