Technical Field

The utility model relates to a technical field of simulation lower jaw mastication device especially relates to a device of imitative lower jaw interlock motion.

Background

Bionic chewing is a device for simulating the movement of upper and lower jaws when people chew, and can simulate and reproduce the chewing process of people. In related experiments in the fields of food science, oral medicine and the like, the bionic chewing device simulates the chewing process of human beings, so that experiments such as food chewing analysis, denture abrasion condition and service life analysis are completed.

The human mandible is driven by masticatory muscles, and does complex opening and closing movement in three-dimensional space relative to the maxilla under the constraint of temporomandibular joint. The human jaw opening movement is divided into three stages of small jaw opening movement, large jaw opening movement and maximum jaw opening movement. When the jaw is slightly opened, the lower jaw descends by about 2cm, and the condyles only rotate. When the jaw is opened greatly, the lower jaw descends by about 2cm, and the condyles do not only rotate but also slide. The maximum jaw movement, such as the mandibular movement at yawning, is the maximum jaw movement. Generally, the most common movements during chewing are small and large jaw movements.

To achieve a better simulated occlusion process, a chewing device is needed to perform the chewing motion of a biomimetic mandible.
