The utility model relates to a cold compress analgesic device for postoperative nursing of oral cavity, including gauze mask unit, a plurality of cold compress units, a plurality of analgesic units, first fixed unit and second fixed unit. Its advantage lies in, and the gauze mask unit is worn in the place of suffering with the gauze mask form to carry out analgesia and cold compress with analgesic unit, cold compress unit respectively with gauze mask unit is detachably connected, and utilizes first fixed unit and second fixed unit, not only can liberate patient's both hands, and can be closely combined with the place of suffering, and the use is flexible, convenient, and the cold compress, analgesic effect is good, and the gauze mask unit is set up in the region, can carry out cold compress and analgesia to maxillary region, mandibular anterior tooth area, mandibular posterior tooth area respectively, improves patient's comfort.

The application discloses an individualized muscle function growth adaptive orthodontic retainer, a design method and a system, relates to the technical field of tooth correction, and the method comprises the following steps: constructing an annual physiological growth value; constructing a front tooth area inertia coefficient and a back tooth area inertia coefficient; constructing an initial tooth and jaw digital model; determining a target tooth and jaw digital model of optimized occlusion relationship according to the initial tooth and jaw digital model; constructing a front tooth rebound prediction model and a back tooth rebound prediction model according to the front tooth area inertia coefficient, the back tooth area inertia coefficient, the initial tooth and jaw digital model and the target tooth and jaw digital model; generating an orthodontic retainer model according to the target tooth and jaw digital model; respectively constructing avoidance spaces on tooth grooves and tracks of the orthodontic retainer model according to the annual physiological growth value, the front tooth rebound prediction model and the back tooth rebound prediction model; and respectively adjusting the lip baffle wall thickness and the cheek screen wall thickness of the orthodontic retainer model according to the front tooth area inertia coefficient and the back tooth area inertia coefficient. By adopting the application, the orthodontic retainer model is more in line with anatomical physiological facts, and the correction effect is better.
