Digitized double-resistance-plate corrector with oral respiration and mandibular retraction and manufacturing method of digitized double-resistance-plate corrector

Abstract

The invention discloses a digital double-blocking-plate corrector with oral respiration and mandibular retraction and a manufacturing method, and belongs to the technical field of correctors. According to CBCT image data, the mandibular leading amount of a target position is accurately determined, the upper jaw inclined plane magnetic type positioning nail and the lower jaw inclined plane magnetic type positioning nail are symmetrically designed on the occlusion inclined plane, the problem of night dislocation of the functional orthosis is reduced, and the detachable breathing gear can adjust the oral cavity air inflow and promote nasal breathing. The double-resistance-plate straightener disclosed by the invention is more accurate to manufacture by utilizing a digital program, the manufacturing time of the straightener can be shortened, the rework rate of the straightener can be effectively reduced, and benzene and dust pollution in a traditional process can also be avoided. Meanwhile, more reasonable step-by-step design and staged corrector manufacturing can be carried out on the lower jaw leading amount by utilizing a tooth jaw model and jaw bone three-dimensional data of a patient, so that the comfort level and the treatment safety of the patient are effectively improved, and meanwhile, the method can be synchronously used for auxiliary treatment of oral respiration.

Description

technical field [0001] The invention belongs to the technical field of orthosis, and relates to a digital double-blocking plate orthosis with mouth breathing and mandibular retraction and a manufacturing method. Background technique [0002] Osteomandibular retraction in adolescents and children is a common clinical dental and maxillofacial deformity, which is often associated with mouth breathing. At present, clinically, mainly by making muscle function appliances such as Activitor, Twinblock, etc. to promote the growth and development of the mandible, improve the patient's facial shape, and at the same time correct the relationship between the upper airway, the tongue and the soft palate, improve the patient's respiratory function, and relieve clinical symptoms. Clinically, because patients wearing Twinblock can still speak freely, the clinical application is more extensive than Activitor. [0003] 1) At present, the production process of functional orthodontic appliances...
