Description

Multifunctional face deflection measuring and indicating device

Technical Field

The invention relates to a multifunctional face deviation measurement indicating device.

Background

With the increase of living standard, more and more patients begin to understand and receive orthodontic treatment to beautify their appearance. From the orthodontic point of view, in addition to correcting the deformity of the teeth themselves, the aim of the treatment is mainly to correct the asymmetry and deviation of the oromandibular aspect of the patient due to the congenital dysplasia, for the overall appearance and appearance of the patient. In clinical practice, patients with mild asymmetry do not require treatment, but patients with moderate and severe asymmetric facial deformities clearly require orthodontic treatment. Because the whole function of the face of the patient is greatly influenced, daily language, food intake and the like cannot be normally finished, and the obvious deformity of the appearance can bring heavy burden to the mind and body of the patient.

However, in the treatment process, the condition of a patient is mainly judged by visual subjective estimation of an orthodontist at home at present, and the conditions of difficult clinical diagnosis and missed diagnosis sometimes occur. The reason for this is that no objective measuring tool or method is available at present, so that doctors can intuitively and objectively display the severity of facial deviation through specific measured values, and one point that diagnosis and treatment become more difficult is that no objective index is available to evaluate the treatment effect of patients in different stages before, during and after treatment. This results in a more subjective correction of orthodontic treatment, as well as difficulties in communication between and increased patient-patient conflict. In addition, the contradiction is increasingly prominent at the present time, which is the rapid development stage of orthodontic treatment in China, and therefore, the solution of the problem is urgent.

And the system also has a little complement, so that an effective measuring tool is also very lacking in diagnosis and treatment processes of neurology department for specific facial changes such as facial paralysis, facial distortion, nasolabial sulcus depth change, palpebral fissure width and the like of patients caused by diseases such as cerebral apoplexy, facial neuritis and the like, so that the system can be used for determining the symptoms of the patients and assisting diagnosis. Only about 200 people have the disease rate of stroke in 10 ten thousand people in China, and other diseases such as facial neuritis and the like are common diseases of the neurology department.

In summary, whether each part of the face is deviated or not and whether the other parts are deviated or not are mainly judged by visual estimation of a doctor, and there is no objective judgment method. The above-mentioned problems are problems that should be considered and solved in the multifunctional deflection measurement process of the face.
