1. Is it necessary to separate the teeth for orthodontics?
Orthodontics is not necessary to separate teeth. Today’s domestic orthodontic treatment, the proportion of the orthodontic treatment is increasing year by year, it can be expected that the orthodontic treatment will become mainstream. Must be divided teeth will be less and less.
2, the role and principle of tooth separation?
(Orthodontic teeth why split teeth) split teeth is to make rings for large teeth!
Split teeth, is the preparation work before wearing full orthodontic appliances, the doctor put the split teeth elastic rubber ring (or split teeth spring) on both sides of the patient’s big teeth (usually the sixth tooth), after 5-7 days of split teeth can get a tiny gap on both sides of the sixth tooth, to put a band ring on the sixth tooth, the band ring welded a buccal tube, this buccal tube is wearing wire. Since the teeth are too close to each other to put the band ring on the molars, it is necessary to put a split ring (or split spring) in the front and back of the number six teeth to make the teeth contact not too tight and get a small gap to put the band ring in.
3. Why can orthodontics be done without splitting teeth?
The band ring is made to weld the buccal canal. In the past, the bonding force of the adhesive was not strong enough, so the buccal tube could not be directly bonded on the molar side (easy to fall off), with the improvement of bonding, now use the light-curing adhesive (through the light-curing lamp emits a beam of pure blue light on the adhesive to trigger its bonding force to maximum effect), it is possible to achieve the buccal tube directly bonded to the tooth surface of the sixth and seventh teeth.
Direct bonding of the buccal surface canal eliminates the need for tooth separation.
However, because the cost of light-curing adhesive is much higher than the domestic traditional orthodontic adhesive, the use of domestic adhesive directly bonded buccal tube is also feasible, but the rate of loss of buccal tube will be higher, so some doctors still choose to do the practice of splitting teeth with ring.
4.What circumstances must be divided?
There are some cases that require tooth separation. For example, if you need to take measures to enhance the support of the molar teeth, you need to use the trans-palatal bar (TPA), the Nance arch (Nance bracket), the extra-oral arch, etc., you need to make a band ring and connect the metal bar with these support measures through the band ring.
However, with the widespread use of implant staples, there are now very few cases where the transverse palatal bar (TPA), the Nance arch (Nance brace), and the extraoral arch are necessary, and it can be said that the implant staples have basically replaced these bracing measures.
Therefore, it is now very rare to have to do braces, and it is basically possible to avoid splitting teeth and doing braces. However, this depends largely on the orthodontist’s preference and design, and is not something that the patient can influence. The patient can only choose his orthodontist, but cannot ask his orthodontist to give up splitting for him. The implant nail is the most effective support measure, mini, comfortable and effective, and the one circled below is the implant nail (bone nail).
5. Comparison of split teeth and non-split teeth.
Direct bonding of the buccal canal and split teeth to do with the ring has a number of advantages in contrast, including.
(1) to avoid the pain of tooth separation (some people feel that the pain of tooth separation is far greater than the pain of wearing orthodontic appliances with force, and some people even give up orthodontic treatment in the middle of tooth separation because they can not stand the pain of tooth separation).
(2) Avoiding the food embedding on both sides of the molars with rings.
(3) The small size of the buccal canal makes local hygiene better and easy to clean.
(4) Avoid gingival recession and gingival inflammation caused by molar teeth with rings.
(5) When the aligner is removed at the end of the orthodontic course, the sequelae of easy food stuffing on both sides of the molar teeth caused by the thickness of the band ring are avoided.
(6) The practice of splitting teeth: after the splitting of teeth to obtain a gap to make the band ring, the arrow in the figure below shows the band ring glued to the molar teeth, and the band ring is welded to the buccal tube (buccal tube is used to thread the wire).
As shown, during orthodontic treatment, it is difficult to clean the area (compared to the case of direct bonding of the buccal tube) because the teeth with the band ring and the front and back teeth are prone to food embedding and cleaning, resulting in inflammation, localized gum swelling and bleeding, etc. When the band ring is removed, a tiny gap remains (band ring thickness), which is more long-term sequelae that cause food embedding.
(7) do not divide the teeth practice: the use of imported bonding agent can be used directly bonded buccal tube, eliminating the pain of dividing the teeth and doing band ring, and bonded buccal tube is small, hygienic and comfortable!
6, how to solve the sequelae of food impaction caused by splitting teeth to do band ring.
The doctor should be asked to remove the band ring about two months before removing the full mouth bracket aligner, so that there is a slight gap on both sides of the molar doing the band ring, and the gap caused by the thickness of the band ring is closed by a slight force, and only then the mold is taken for the retainer. This way, it will not trigger the sequelae of food impaction in the split teeth for the band ring.
