The present invention is a device for simulating lower jaw activity. The device can be utilized in cooperation with an artificial intelligent lower jaw occlusion and attitude recording device. The device comprises a base, an upper jaw tooth mold, an opening and closing rotating platform, a left and right rotating platform, a horizontal rotating platform, a front-back shifting platform and a lower jaw tooth mold. The present invention makes it possible to make lower jaw moving forward and backward, opening and closing (pitch), tilting left and right (yaw), in place rotating (yaw), and etc. Then, according to the data obtained by the artificial intelligent lower jaw occlusion and attitude recording device, the lower jaw activities concluded through the reverse engineering by means of the present invention facilitates production of accurate intra-oral device, and can be applied to unknown complex actions in dental medical research, such as occlusion, bruxism, swallowing, sounding, and etc.

An animal dentistry apparatus is provided and comprises a jaw assembly. The jaw assembly comprises a lower jaw and an upper jaw, and is configured such that the lower jaw and the upper jaw can move apart and together in a mastication action. The upper and lower jaw comprise at least one tooth. The apparatus further comprises a means, such as a motor, to effect the mastication action. The animal dentistry apparatus may be used to assess a chewable product, and such methods are also provided.

A method for modeling mandibular motion, executable by an electronic device and including: acquiring a point cloud representing a mandible; determining an initial condyle pose; determining natural movement parameters for the condyles including maximum protrusion displacement, a Bennett angle, and a Sagittal inclination path angle; receiving an indication of a translation and/or a rotation of the mandible; determining a first natural movement of translation including a protrusion followed by a first sagittal inclination; determining a second natural movement of rotation including a Bennet movement followed by a second sagittal inclination; applying the natural movement s to the point cloud to form a transformed point cloud; creating a model of the mandible having undergone the at least one of the translation and the rotation using the transformed point cloud; and displaying the model of the mandible having undergone the translation and/or rotation.
