The invention relates to the field of clinical orthodontics of oral cavities, and discloses a dental appliance, a generation method of a digital model of the dental appliance and a manufacturing method of the appliance. The generation method of the digital model of the dental appliance comprises the steps that an initial tooth-mandible digital model is acquired; according to the initial tooth-mandible digital model and orthodontic target information, a target tooth-mandible digital model is constructed; according to the initial tooth-mandible digital model, the target tooth-mandible digital model and material information, orthodontic force information used for generating the target tooth-mandible model is acquired by adopting a finite element analysis algorithm, and an appliance digital model matched with the orthodontic force information is constructed. According to the scheme, a scheme that the appliance matched with the orthodontic force information can be directly manufactured is provided.
Description
technical field [0001] The invention relates to the field of oral clinical orthodontics, in particular to a method for generating a dental appliance and a digital model thereof, and a method for manufacturing the appliance. Background technique [0002] Dental deformity is one of the three major diseases of the oral cavity and has a high prevalence rate. The vast majority of malocclusions occur during growth and development, and are caused by congenital genetic factors or acquired environmental factors, such as diseases, bad oral habits, abnormal tooth replacement, etc., resulting in tooth, jaw, and craniofacial deformities, such as tooth arrangement Misalignment, abnormal jaw relationship between the upper and lower dental arches, etc. Malocclusion will bring great harm to the oral cavity and even the whole body: affect the development of maxillofacial, oral health, oral function, appearance, etc. At present, patients are treated by surgery or wearing orthodontic applianc...
