Description

Multifunctional invisible appliance

Technical Field

The utility model relates to an oral medicine technical field especially relates to a ware is rescued in multi-functional stealthy.

Background

Malocclusion deformity is a deformity of teeth, jaws, and craniofacial surfaces caused by congenital genetic factors or acquired environmental factors, which affects the beauty of the face and the mouth and jaw functions of a patient and harms the health of the body, mind and body. Bad habits in children's mouth are one of the major environmental factors that lead to malocclusions. The bad habits of the oral cavity mainly comprise lip habits, tongue habits, finger sucking habits, object biting habits, mouth breathing habits and the like. If the bad habits of the oral cavity are not timely broken, the muscle forces of the inner side and the outer side of the dental arch are in an unbalanced state for a long time, thereby influencing the growth and development of the jaw bone and dentition, causing or aggravating the abnormity of the tooth arrangement and/or the form and position of the jaw bone, and forming various types of malocclusion deformities. For example, finger sucking habits and object biting habits can cause upper arch stenosis, upper anterior protrusion, anterior open bite, and the like; the tongue extending habit and the tongue spitting habit can cause the lower anterior teeth gap, the anterior teeth reverse occlusion, the open teeth occlusion and the like; the lip biting habit aggravates the protrusion of the upper teeth, the deep coverage of the front teeth, the retraction of the lower jaw and the like; the habit of mouth breathing may cause the palatine flap to arch high, the upper anterior teeth to protrude forward, the long profile, etc. The oral cavity bad habit should be discovered as soon as possible, psychological dispersion and supervision should be carried out in time, the bad habit should be corrected automatically by guiding the bad habit, if the bad habit cannot be corrected automatically, the sick children should be assisted by adopting a proper appliance according to the etiology to break the bad habit, the occurrence and development of malocclusion deformity are prevented, and the existing malocclusion deformity is corrected.

At present, the correction device aiming at the bad habits of the oral cavity mainly comprises a muscle function corrector and a traditional movable corrector. Wherein, the individuation degree that ware was rescued to flesh function is low, can't carry out accurate the correction to the different condition of different individual jaw and dentition. The traditional movable appliance has narrow functional range and poor aesthetic degree and comfort. The patent of the appliance for guiding the mandible forwards and/or breaking the bad habit of sucking the lower lip and the preparation method (201510200573.3) improves the traditional removable appliance, but still has the following disadvantages: 1, the wearing comfort level is poor, the aesthetic degree is poor, sharp structures such as steel wires stimulate oral mucosa, and the compliance of a patient is poor in the long-term wearing process; 2, the dentition cannot be aligned, and the existing malocclusion deformity is corrected inefficiently. The patent ' bracket-free invisible appliance with tongue spines ' (201521117682.0) ' provides an appliance which is beautiful and comfortable, but has single function, limited tongue spines which are key functional components and low correction efficiency.

The children have high prevalence rate of bad habits in oral cavity, and the individuals often have two or more bad habits simultaneously and are accompanied by different degrees of malocclusion deformity, and the treatment effect of the children is obviously influenced by the compliance of patients. Therefore, there is a need for an appliance with high wearing comfort, good patient compliance, wide application range, and high treatment efficacy for a variety of oral cavity bad habits. None of the prior art meets the above requirements.

The term "occlusal" in this text is a term of professional vocabulary in oral medicine, English is oclusion, and the term "occlusal" is a left part and a right part of a character, and the character cannot be found in a common character library, so that the term "occlusal" is written separately.
