leukoplakia and other diseases, through the technology, a plurality of periodontal diseases can be completely cured, and the development of the tissue bioengineering technology is as follows: the guided tissue regeneration technology, the gene technology, the artificial tooth implant and the like bring exciting hopes for the regeneration of the diseased teeth, but the treatment of the periodontal disease is necessarily a sequence treatment, a detailed and effective treatment plan is made in the treatment process, the meticulous treatment of doctors and the positive cooperation of patients are the key points of successful treatment, the oral cavity is the initial part of the digestive tract, the oral cavity is communicated with the outside through a cleft mouth and is continued with the pharynx through the isthmus, the teeth, the tongue and other organs are arranged in the oral cavity, the front wall of the oral cavity is the structures of the buccal cavity, the side wall is the cheek, the top is the palate, the bottom of the oral cavity is the mucous membrane, the muscles and the like, the oral cavity is divided into the oral vestibule at the front outer side part and the inherent oral cavity at the rear inner side part through the upper dental arch and the lower dental arch, when the upper dental arch and the lower dental arch are occluded, the oral vestibule is communicated through the gap behind the third molar tooth, and when the patient is clinically closed, the mouth opener or the channel can be arranged, injecting medicine or nutrient substances, simultaneously preventing biting of tongue, the oral cavity is an important organ of human body, is positioned at the initial part of digestive tract, has the primary digestion functions of chewing, secreting saliva, stirring and swallowing food, and has the important functions of assisting pronunciation, maintaining normal face appearance form and carrying out daily social interaction, the front part of the oral cavity is lips, two side surfaces are cheek parts, the back part is pharyngeal cavity, the upper part is palate, the lower part is mouth bottom, the tongue is positioned in the oral cavity, the inner surface layer of the whole oral cavity is mucous membrane tissue, gingiva, chewing muscle group, expression muscle group and three oral cavity salivary glands are soft tissues, teeth, alveolar bone and jawbone are hard tissues, particularly the teeth are the hardest tissues in the body, so the function of cutting and grinding food can be played, the tongue is composed of muscles, the rotation in the oral cavity is flexible, so the pronunciation and the stirring and the food conveying can be assisted, the surface of the tongue has a plurality of small nipples and rich taste receptors, can feel and distinguish various tastes of acid, sweet, bitter, spicy, salty and the like, the tongue frenum is arranged in the middle of the lower part of the tongue and plays a role of connecting the tongue with the bottom of the mouth, if the tongue frenum is too short, the tongue cannot move conveniently and cannot pronounce clearly, a small operation needs to be performed for correction, parotid, submandibular and sublingual glands are arranged in the oral cavity, in addition, a plurality of small salivary glands can secrete saliva about 1.5 liters every day to lubricate the oral cavity, mix food masses and facilitate swallowing, a plurality of digestive enzymes are contained in the saliva secreted by the salivary glands to have preliminary digestion effect on food, the saliva also contains lysozyme and immune protein antibodies, the dissolving, destroying and inhibiting effects on bacteria are provided, the saliva can be fully chewed by nerve reflex to promote the secretion of the saliva, the digestion and the oral hygiene of the food are facilitated, the variety of bacteria in the oral cavity is complex, and the reason that the oral cavity does not have diseases at ordinary times is that a defense mechanism is provided in the oral cavity, the oral defense mechanism comprises the functions of oral anatomy and physiological barrier, phagocytosis of leucocytes and macrophages, humoral antibodies and cell mediated reaction, an oral appliance, also called as a dental appliance or a dental appliance, belongs to tools used by oral medical specialties, has a general structure which is not very complex, does not have a circuit board or an integrated block, does not need to be electrified, has the characteristic of repeated use, forms three main supports of the oral industry together with oral consumables and oral large-scale equipment, and is a matched appliance used for oral surgery or operation places in the oral cavity, particularly has different types according to different use purposes, is used as an auxiliary appliance in maxillofacial surgery, is mainly used for clamping hard tissues such as jawbone, and the orthognathic surgery of the oral cavity is an important branch and a new science of the oral and maxillofacial surgery, the oral cavity pliers are mainly used for clamping the lower jaw ascending and descending front edge and blocking the soft tissues and the mouth corners of the ascending and descending front edge, thereby being beneficial to exposing the surgical visual field and simultaneously protecting the surrounding soft tissues from being damaged; when the oral cavity of a patient is inspected and treated in the oral operation work, the patient needs to open the oral cavity independently, but in the inspection process, the oral cavity of the patient is easy to move, the inspection is affected, and supporting forceps with expansion and supporting functions are usually needed to assist the patient to open the oral cavity or keep the open state; nevertheless support formula oral cavity operation pincers under the prior art, simple structure is mostly the integral type structure, can not assemble and dismantle, when support formula oral cavity operation pincers take place to damage, is not convenient for maintain support formula oral cavity operation pincers, and life is lower, and the practicality is relatively poor.
