Missing teeth, also known as the wrong tooth abnormalities, he was referring to children in the process of growth and development, by the inherent genetic factors or the day after the environmental factors, such as disease, bad oral habits, such as lead to abnormal tooth for tooth, jaw, the craniofacial Deformity, include: irregular teeth alignment, the upper and lower dental arch occlusal relationship between the abnormal size of the jaw shape, such as abnormal position.
【Response】
Dentition occurred has been missing children; no matter what the cause, doctors can be used by the dental appliance or decreases to give treatment. Subtrahend law through the removal of dentition in 12 crowded teeth, 9 to 10-year-old pulled out when the milk teeth, so that the neighboring canine or premolar eruption: 2 ~ 17-year-old pulled out when the unilateral or bilateral double Canine, so that strong features. Oblique position of the canine eruption. A fixed appliance and activities of the two. Fixed appliance is to be fixed in the treatment of teeth and adjacent teeth, the teeth through the circle and bolt silk knot, and so on, will be missing teeth alignment correction pressure. Treatment by a doctor during the adjustment wells appliance periodic inspection force. Fixed appliance has the advantage of a solid and comfortable to wear, but more complicated to produce. Activities of the appliance through the steel wire Hyperbolic bow lips, cross-bow lips and a spring song, and other means of dental treatment for arrhythmia. They have the advantage of easy production, treatment may take off during brushing.
7 to 12-year-old tooth is developing Huanya period. Dentition is missing at this time appears for the time being, after the self-correction. However, there can not be part of the self-correction, they need dental treatment from doctors.
13 to 17-year-old is the permanent tooth development period. In this age period has been overwhelming majority of permanent teeth eruption, the width of the arch and facial shape gradually, so this will not happen on its own dentition missing a turn for the better, we must make a positive correction.
【Cause】
Jaw deformity wrong form factor and its mechanism is complicated. The process may be occurring by a single factor or a single mechanism is at work, but it may be a number of factors or more of a common mechanism of the result of these factors affecting the maxillofacial bone, nerve, muscle, teeth and soft tissue growth and development To occur and then the formation of abnormal changes in the wrong tooth abnormalities.
The wrong factors in the incidence of tooth deformity is generally hereditary and acquired two major categories of factors. Genetic factors for the evolution and degradation of the race, genetic factors account for about 30%. Acquired factors are the following:
(1) early loss of primary teeth: there will be less space, resulting in crowded dislocation. Meng lost their lead role of the eruption of permanent teeth and can not be wrong when eruption.
(2) bad habit: for the majority of the means used to suck, tongue habits, habits Yaochun, bite-habit of stretching the mandibular habits, bad habit of swallowing, unilateral chewing habits can cause a wide range of malocclusion.
(3) teeth: teeth can cause tooth and jaw shape of the energy system disorders, in inter-incisor teeth can lead to the formation of the central incisor gap, and so on.
(4) congenital missing teeth: embryonic development and for more reasons, the third molar missing for more than phylogenetic regression.
(5) stranded deciduous: individual teeth overdue for the loss of primary teeth stranded, following the lead for the eruption of permanent teeth were stopped and were ambushed by the eruption or dislocation.
(6) Rujian less tooth wear: Because of the food children eat too soft, so some Rujian tooth wear more than other teeth, which dental arch above the surface, resulting in early contact, resulting in the front or lateral movement, the formation of anti - Teeth.
(7) There are thousands of local and systemic diseases, such as infectious diseases, malnutrition, endocrine factors, lack of vitamins, cleft lip and palate, mandibular condyle benign hypertrophy, such as facial mast.
】 【Prevention
Prevention of irregular dentition effective way to avoid the unfavorable factors at the same time, children from the eruption of primary teeth begin to take some attention should be on the way to promote the development of the mandible.
To promote the development of the jaw and more convenient method, a simple and effective way so that teeth have more opportunities to receive training. Children in primary molars after the eruption, often giving them food to eat some of the stubby, such as dry bread, Huanya period to give the children eat sugar cane, Wu Xiangdou and so on, of course, have to be careful not to eat perishable foods, such as moldy peanuts, and so on, In order to avoid more losses than gains, and other adverse consequences.
As a result of today's human society towards the fine aspects of Catering development of the jaw lack of stimulation can easily lead to jaw dysplasia, and the formation of irregular dentition, and so on. So eating those foods crude is necessary. However, when the food must pay attention to both sides of the teeth together with chewing, or the side of too much exercise, too little exercise on the other side, because of the jaw can also stimulate the jaw deformity due to the uneven and irregular dentition, and Since the unilateral chew, and led to the development of facial asymmetry. The stubby one should not eat more food, you can eat every day quantitatively from time to time, parents should also be directed to prevent children form bad habits.
