The object of the present invention relates to a method for the production of an orthodontic orthopedic functional apparatus for the treatment of facial asymmetries. The present invention refers to the field of the technique comprising the manufacturing methods and the technique used to make orthodontic appliances. Specifically, it refers to a methodology that allows the artwork to be performed and without making the dependent operator, operation based on a cephalometric frontal tract generated by a computer so without ever coming into contact with the patient, a device functional orthodontic orthopedic for the treatment of facial asymmetries.
Facial asymmetry is the alteration of skeletal growth which can be determined by several congenital or acquired factors that in skeletal development patients undergoing pathogenesis by altering the harmonic functionality of the whole stomatognathic apparatus. Among the unilateral development asymmetries there are congenital forms such us Hemifacial Microsomy, and shapes acquired as the outcome of condylar fractures that find the most pathological manifestation in cases where an ankylosis of TMJ is determined. The Hemifacial Microsomia manifests itself as a more or less acute structural and functional alteration of the maxilla facial complex. The goals of functional orthodontic therapy are to stimulate the functions of the stomatognathic system to perform vicarious functions for the absent structures and to stimulate a differential increase on both sides. Fractures of the mandibular condyles are a traumatic pathology often encountered in children following accidental falls and even in these cases the correct diagnosis and detection of anatomic damage will suggest the most appropriate orthodontic or surgical treatment to be performed. Facial symmetry break the equilibrium and symmetry of the line of the face and jaw. This problem reduce self-esteem, malnutrition can also cause mandible disabilities when bitten or masticated, in addition to digestion problems. To date, there are several orthodontic appliances to correct this disease. However, most of them act indirectly on the problem by inserting interlocking thickness on the healthy side and placing a guide on the other side in order to correct the disease. Using these devices involves very long therapy times, most of them also require the patient to keep them in their mouths all the time; these types of device require high patient collaboration so therapy cannot start at a very early age.
However, in the state of the art is an innovative functional orthodontic device for the treatment of facial asymmetries which aims to increase the mandible's verticality in order to correct asymmetry less invasively than current device such as the presented in the patent document with application number PCT/IB2015/000277. This device consists in a bite (18) which Cover the upper arch having a thickness corresponding to the front portion of the asymmetrical side which starts from the canine descending proportionally to the molar Table 2.

The benefits of using this device are many. It is applied to upper arch, the application requires little work on the operator's dental chair, directly stimulates the mandible, the patient is not obliged to have his mouth closed, but only the search for contact during the swallowing, simplicity of the device which allows very early start of the functional therapy and prevents the structure of defect in the muscles, soft tissues etc. does not require a great collaboration of the patient, it can also be used only after dinner and during the night. The technical problem in the state of the art relates to the physical realization of this type of apparatus which has nowadays been empirically characterized, relying solely on the skill and experience of the technician who builds it on the basis of a dental cast (21) of the patient Table 2
Therefore, it is possible to make the device in a state of art and without the risk of making mistakes related to the operator's limited experience.
Invaluable are the advantages of using this methodology that allows anyone and anywhere to create a functional orthodontic device for the treatment of facial asymmetries based on a frontal cephalometric tract generated by a computer without ever coming into contact with the patient. Anyone of the craft may better understand the invention by a detailed description of the drawing as follows.
