Description

Method for manufacturing digital jaw position relocater for children

Technical Field

The application relates to the technical field of orthodontic, in particular to a manufacturing method of a digital jaw position relocator for children.

Background

At present, with the development of economy, early intervention correction and orthodontic treatment of children are widely regarded by parents, the acceptance and demand rate are high, and more stomatologists are promoted to develop towards the early intervention correction and orthodontic treatment of children. However, the professional awareness of doctors currently engaged in the work is different, most doctors only pay attention to the movement of teeth, the knowledge of the growth change of the mandible position and the occlusion relation of children in the growth and development stage is lacked, the knowledge of influencing the correction strategy by stimulating or inhibiting the bone development or changing the mandible position is lacked, and the practical experience of occlusion reconstruction technology is clinically lacked, so that the effective technical means and the accurate treatment result are lacked when the mandible positioning treatment is carried out on children patients.

The existing children treatment aiming at mandibular retrosystole, underbite and offsite has appliances with various forms, except for most appliances which are treated by moving teeth, functional appliances aiming at mandibular functional protrusion, retreat and offset are also available, but because of complex structure, doctors with higher technical level and more treatment experience are needed for use, so the used doctors are fewer, especially the key of successful functional correction treatment is accurate occlusion reconstruction, and the occlusion reconstruction needs enough experience of the doctors and the matching degree of the sick children, so the treatment is often difficult to develop by the doctors.

And the children patients with facial dysplasia and joint dysplasia caused by jaw position abnormality can solve or relieve the existing dysplasia by adjusting the jaw position within proper physiological age, so as to avoid causing more serious deformity. When the associated cognition of the doctors on the maxillology and the orthodontics is insufficient and the doctors do not know to treat the children correctly, the doctors dare not to take a diagnosis easily, so that the children with the diseases cannot be treated effectively after misdiagnosis or refusal of the doctors, the abnormal development of the children with the diseases is continuous, and the physical and psychological health of the children with the diseases is greatly influenced.

Although there is also doctor to receive a doctor's visit, the jaw position of current function correction ware is rebuild and still relies on doctor's experience, operation skill and infant's cooperation degree clinically, because of factors such as the operation degree of difficulty is great, infant's age is less and facial muscle is nervous, often can't obtain accurate position, leads to jaw position record inaccurate, corrects the ware preparation inaccurate, and curative effect is not good, and the infant also often is relatively poor because of painful compliance.

In summary, the existing treatment methods have great limitations, are easy to delay the treatment of the children patients or cause that the jaw position relationship after the treatment cannot be coordinated and stabilized, have higher recurrence risk or need to be maintained for a long time, and cannot predictably change the occlusion condition by changing the position of the lower jaw to stimulate or inhibit the growth of the lower jaw to guide and improve the facial structure and the beauty of the patients, even cause iatrogenic temporomandibular secondary diseases.
