The invention discloses an intelligent occlusal device for recovery after operations of the oral cavity and relates to the technical field of recovery after the operations of the oral cavity. The intelligent occlusal device comprises a central rotating drum; diameter adjusting devices are fixedly connected to the symmetric portions, on the two sides of a counting bearing, of the outer surface of the central rotating drum respectively, and gear rebound devices are fixedly connected to the symmetric portions of the sides, away from a protective interlayer, of the adjusting devices respectively;a pressure adjuster is fixedly connected to the side where the gear rebound devices are close to each other, a micro current acupuncture apparatus is fixedly connected to the sides, away from the adjusting devices, of the gear rebound devices, and the end, away from the gear rebound devices, of the micro current acupuncture apparatus is fixedly connected with a contact switch. According to the intelligent occlusal device, the nerves can be stimulated through electric current acupuncture to help patients suffering from numbness and other nerve injuries after the operations of the oral cavity torecover the perceptual motion as soon as possible; moreover, the occlusal device can be used for mouth opening training, patients who have difficulty in opening the mouth can conveniently open the mouth, the strength of electric current is low, the personnel safety is ensured, and the intelligent occlusal device is small in structure and convenient to use.
