Under normal circumstances, when the upper and lower teeth bite together, the upper front teeth should bite on the outside of the lower front teeth, if the opposite (i.e., the lower front teeth bite on the outside of the upper front teeth), in medical terms, it is called “anterior teeth together”, “anterior teeth together”, commonly known as “It is also called “pocket tooth”.
Since “enamel” tends to get worse as it grows without treatment, it is best to have it corrected as early as possible. For patients who have parents or relatives with “bunions”, there is a possibility of recurrence with growth and development after correction, so many cases have to be treated in stages and the correction time is longer.

Diastema in permanent dentition
Treatment of “Diastema” in the milk period: the best time for orthodontic treatment is from 3 to 5 years old, if the time of orthodontic treatment is too early, it is difficult for the child to cooperate with the treatment; while too late (6 to 7 years old), the permanent teeth begin to replace, and the roots of the milk teeth have been absorbed, which makes the treatment difficult. At this time, the application of simple movable braces or functional braces can receive very good results. It is generally believed that more than half of the milk teeth “envelope” without correction will develop into permanent teeth “envelope”, and the symptoms will be aggravated; milk teeth “envelope” after correction, permanent teeth After the correction of the “encrustation” of the milk teeth, the possibility of “encrustation” of the permanent teeth is reduced, even if it occurs, the symptoms are mostly mild.
The treatment of “encrustation” during the period of teeth replacement: the treatment at this time is complex and variable, and may involve a variety of braces for different situations, including movable braces, functional braces, fixed braces and extra-oral braces, etc. The main purpose is to use the growth potential of children during the growth period to change the amount and direction of bone growth.
The treatment of “Diastema” in early permanent teeth: mainly refers to the adolescents whose teeth have just been replaced, when most of the development of jaws and teeth has been completed, mainly fixed braces are used to disguise the skeletal deformity by changing the position of teeth. At this time, a small number of patients need to undergo combined orthodontic and jaw surgery in adulthood because of the seriousness of the skeletal deformity.
Treatment for adults with “Geodontia”: For adults with mild skeletal deformities, the treatment can still be disguised by changing the position of the teeth through fixed braces; for adults with severe skeletal deformities, the treatment can only be done through orthodontic surgery. For adults with severe skeletal deformities, the only treatment is a combination of orthodontic and orthognathic surgery.
The following is a brief introduction to several commonly used treatment of “encephalitis” braces and orthodontic methods, in the clinical orthodontist will choose the appropriate braces and orthodontic methods according to the different conditions of the patient.
A, simple movable orthodontic appliance
Mainly used for the period of milk teeth or period of replacement teeth, “Diastema”, mainly composed of composite resin and steel wire bending of various curves, can be taken off by the patient to wear, generally require eating must wear aligners.
Second, the front traction orthodontic appliances
Suitable for patients in the growth period, preferably around the age of 8 to 11 years old. It is used to correct bony maxillary recession and stimulate maxillary bone growth. The orthosis consists of two parts: the intraoral component is a movable or fixed orthosis, and the extraoral component is a mask traction bracket, which is connected to the two parts by an elastic rubber band. Some patients with “diastema” have upper and lower arch width disparity and need to be treated with arch expansion in conjunction with anterior traction.
Third, the head cap chin pocket traction orthodontic appliance
It is a common means of inhibiting jaw growth for patients with bony or functional “geodontia” during the growth period. It consists of a head cap, a chin pocket and an elastic band.
Frankel III functional orthosis
It is mainly used for functional “geodesic” and early bony “geodesic” caused by abnormal function of the orofacial muscles, and the most suitable age is 7~9 years old for girls and 10~12 years old for boys.
V. 2×4 orthodontic technique
It is mainly used for dental or mild bony “geodesic” during the period of dentition, and only cemented orthodontic appliances on the erupted permanent teeth to release the anterior teeth “geodesic”.
Sixth, fixed orthodontic appliances masking treatment
For early permanent teeth and adults with mild “ingrown teeth”, the teeth can be moved by conventional fixed orthodontic appliances to disguise the skeletal deformity. If there is also crowding of teeth, tooth extraction may be required.
Seven, orthodontic – jaw surgery combined treatment
Severe orthodontic-jaw surgery is required in adulthood for severe bony “geodontia”. It takes about one year for the orthodontic treatment to align the teeth before the surgery, about ten days for the surgery, and about six months to one year for the orthodontic treatment to fine-tune the bite relationship after the surgery, and about two years in total.
