How to maintain after orthodontics

How to maintain the state of the newly corrected teeth after orthodontics, or how to maintain the state of the young teeth, because with the loss of time, everyone’s teeth state will also be aging, and certainly not when young In the same way, the teeth move forward and downward continuously, so how to maintain is a matter for everyone who does the correction. How to maintain it, from the perspective of the history of maintenance, the viewpoint of occlusion stability; the viewpoint of apical basal bone stability; the viewpoint of mandibular incisor stability; the muscle stability. &nbsp. Retention of anti-jaw correction. A 2010 study reported that 40% of orthodontists would routinely use mandibular lingual retainers, while 28% would use Hawley retainers, and 18% recommended the use of transparent pressure film retainers. For the upper jaw, 58% of doctors use Hawley retainers, while 30% recommend pressure-retaining retainers. &nbsp.&nbsp.

Those things about orthodontic retainers~

After orthodontic treatment moves the teeth to the ideal position, the alveolar bone still needs a period of time to be built in place again, so that the teeth are stabilized at the new position, so the retention period of orthodontic treatment is very important. In general, we will require It is guaranteed to be maintained throughout the day and evening during the year. If there are special circumstances, or the patient itself has very high requirements for the uniformity of his teeth, it may need to be maintained for life. The position remains unchanged, and it may really need to be maintained for life, but it is not necessary to wear the retainer all day long in the later period, only need to wear it every night or overnight). Three common holding methods&nbsp.&nbsp.&nbsp.&nbsp. First of all, let’s talk about the commonly used pressure film holders in China. The laminator is relatively simple to manufacture and takes a short time. The patient can wear the appliance as soon as possible on the same day when the appliance is removed, keeping the effect good, timely and beautiful. The difference between different film holders is mainly on the thickness and elasticity of the material. At present, the most expensive film holder on the market may be regarded as the Vivera retainer. The Vivera uses the smart track material of the patent. It is more fit and more comfortable than ordinary lamination holder. But if it can be worn as required, whether it is a Vivera or an ordinary pressure film retainer, the retention function is basically the same. As for whether to choose Vivera retainers at a high price, it is actually the same as our daily purchase of various supplies. If the economic conditions allow and there is a high demand for comfort, you can choose the Vivera retainer, if there is no special It is enough to choose ordinary pressure film retainer. The lingual wire is fixed and held. In addition to the film holder, there are many kinds of holding methods/devices. Tongue fixation wire retention is currently the most commonly used and most effective method of preventing anterior teeth crowding/torsion recurrence, but the disadvantage is that it is not conducive to oral hygiene maintenance, especially it will prevent the adjacent surfaces of the upper and lower anterior teeth from being cleaned, but it is used in conjunction with interdental teeth. Brushing and punching can offset this shortcoming. The Hawley retainer is another commonly used retention method. The advantage is that it does not cover the occlusal surface of the teeth, giving the teeth a natural adjustment space, so the occlusal function will be more improved while maintaining. But Hawley retainers also have shortcomings. It has limited wrapping of teeth and there is still some room for recurrence of anterior teeth. Therefore, if there is a case of uneven twisting of the anterior teeth, short roots of the teeth, or more periodontal attachment loss before treatment, doctors often choose to use the lingual side wire to maintain the anterior teeth and cooperate with the pressure film holder or Hawley retainer. . Hawley retainer&nbsp.&nbsp.&nbsp.&nbsp. According to my observations in recent years, the common retention method used by orthodontic doctors in Europe and the United States is that adults often use the lower anterior lingual wire to retain (the lower jaw does not use lamination or Hawley retainer) With the maxillary pressure film holder, teenagers will use the upper and lower jaw Hawley retainers more. Such a retention method is justified: young people have low demands for aesthetics, and need a self-retaining, easy-to-clean retention device, while young people are still in the developmental stage, and the occlusal surface is not suitable for being wrapped, so as not to affect the development of occlusal function And perfect, so the Hawley retainer is very suitable for teenagers; adults pay more attention to aesthetics during the retention process, so the Hawley retainer is not suitable; and the mandibular anterior teeth are the most likely areas of recurrence, so it is more effective to use the lingual wire to maintain; the lower jaw The posterior segment of the teeth is limited by the clamping of the tongue and buccal muscles and the bite. In fact, it is not prone to recurrence, so you can consider not adding a retaining device in the posterior mandibular region of the mandible; The shape of the dental arch is prone to recurrence and deformation, so it is more suitable for the pressure film retainer; the retention force of the maxillary pressure film retainer is sufficient, so the anterior teeth area no longer needs to be used with the lingual wire retention; while the single jaw uses the pressure film retainer, you can do May reduce the impact on occlusion. In summary, this type of retention is an optimized retention method that fully considers all aspects and is worthy of our reference. The two retainers have different aesthetics
