Moving orthodontic appliances

Orthodontic Removable Appliances

Orthodontic mobile devices have two obvious advantages that immediately catch the eye of every consumer: first, they can be removed from the mouth when it’s sensitive, and at least at the beginning of work, patients get better. Accepted. Secondly, they are made in the laboratory, so in the first stages of treatment, the physician takes less time.

These devices also have some disadvantages: the response to the treatment largely depends on the acceptance of the device by the patient and his co-operation, since the device is only effective when used. It is also difficult to obtain two-point contact with these devices, which is essential for complex dental movements. This will limit their therapeutic power. Because of these limitations, the greatest benefit of mobile devices is their use in the first stage of a two-stage orthodontic treatment. Comprehensive orthodontic treatment is performed with fixed devices, not with moving devices.

The evolution of mobile devices

In the United States, Victor Hugo Jackson was among the pioneers and fans of the mobile device in the early twentieth century. At that time there was no acrylic (new plastic material) to make the base plate, nor stainless steel wire to form a springboard. Meanwhile, mobile devices were relatively benign tools that were made from volcanite and their wires made of precious metal or nickel-silver alloy. In the early 1900s George Cruz offered a moving device that was made entirely of precious metal and is still being used. This device has a good maintenance class on the first molars (modified Jakson class), thick wire wires as a frame of the device, and thinner shafts of gold for the desired teeth to move. When the crossover device came in, the regular fixture contained a strap (only on the first molars) and a thick, lobal or lingual wire, the adjacent teeth being closed and moved by the Ligacour’s wires. The crossover machine was a flexible and flexible type of machine. The metal framework and good classmates made the device better than any other mobile device at that time. Classes have sufficient stroke and thus the use of lightweight and elastic elastics of the class || To correct class anomalies || There was a crossover device.

The Cruzette system had some pretty but admirers, especially in the New Orleans area. This device still has fans but generally has little effect on the overall orthodontic process in the United States. From the very beginning, US orthodontic emphasis has been on fixed devices.

The evolution of mobile devices continued for many reasons in Europe, and they remained unaware of fixed devices. There were three main reasons for this:

The belief and bias of the parasite on the ideal occlusion and the attempts to place one teeth in the arc had less effect on the part of the Europeans.

• Social welfare systems in Europe have progressed much faster. This meant more emphasis on machines that could serve as more and be applied by general dentists, rather than limited devices that could only be used by orthodontists.
• Precious metal for fixed devices was less accessible due both to the social consequences (both social systems) and their practical application in dentistry by the German Nazi government, and dentists were only permitted to use other available materials ( Not long after the Second World War, precision steel attachments were not available and fixed machines with precious metals were made).

An interesting result of these issues was that between 1925 and 1965, the orthodontics of the United States almost completely relied on fixed devices, while these devices were essentially unknown in Europe, and all treatments including growth guidance and types Dental movements were performed on mobile devices. Most of the European mobile devices in this period were functional appliances for changing growth. In terms of the definition of a functional device, the device changes the position of the jaw by holding or opening the jaw. A compression that results from muscle tension and soft tissue transmitted to the teeth and bones, changes the teeth and growth. The Manoblucque produced by Robin in the early 1900s is the leading of all functional devices, but the activist provided by Anderson in Norway in the 1920s was the first widely accepted functional device. The Anderson activator was the basis of the treatment called the Norwegian system. Both the system’s system and its theory depended on it in Europe, and in other places, especially in Germany, it was used by Haupl.

The orthodontic movable plates have advantages and disadvantages

In the treatment of mobile devices, an orthodontic device is used for removable plaques that can be removed and repeatedly removed by the patient or by an orthodontist. Although the range of dental movements is less than that of movable plates, skeletal treatments and growth treatments are generally carried out by moving plates, and mobile plates are superior in this regard to fixed devices. However, the use of mobile plates requires less flexibility than fixed devices, and, on the other hand, it is less possible to create unpleasant movements with these devices due to their mobility, if the person treating the principles of proper use and correct use of this To understand the devices, it will be able to easily treat many dental and skeletal abnormalities, thus eliminating the need for complex treatments and even costly and hazardous surgeries. In some cases, the use of some fixed fasteners with mobile plates can greatly increase the ability of this device. These attachments also facilitate extrusion, introspection, rotational modification, or even root aperitifs.

In general, mobile orthodontic devices fall into three groups:

• Functional device: A plate used to change the direction and improve the growth of jaw during growth.
• Patio or Supplementary Plate: A plaque used to preserve treatments performed by fixed or mobile orthodontic devices.
• Activated plaque: A mobile device used in orthodontics for dental movements and other mobile therapy and contains active ingredients.

Fewer costs, better hygiene, the use of byteplan and less time spent in the office are the hallmarks of moving orthodontic appliances.

Advantages of Moving Orthodontic Devices

Moving orthodontic appliances have concessions that are briefly referred to some of them:

They are easy to adjust and have little complexity.

• These devices are made in the laboratory by a technician and therefore the treatment needed to be adjusted in the office is shorter than fixed devices.
  Possibility of using byteplan (for the treatment of occlusal and cross-byte interactions).
  There is a possibility of better observance and more health than fixed devices. Mobile devices can be removed by the patient to clean the teeth and plaque, so they do not cause much oral hygiene.
  Making mobile devices is relatively inexpensive and cost-effective, and in the treatment of these devices, there is no need to buy strap and other expensive accessories.
  It is possible to remove them from the mouth in special cases. As a result, in the first days of treatment, the patient is not accustomed to a mobile plaque, it can use 4-6 hours per day and gradually increase the use time to the desired level. It can also be used in cases where the device is injured and can cause discomfort to the patient.
  The loss of Anchorage in moving plates is far less likely. Because the base plate on this machine also adds the Kam to the Anchorage unit.
  With a mobile device, you can force a few teeth. Therefore, control of dental movements and progress of treatment is easier, but careful attention is required.
  It is possible to perform treatments such as restorative or preventive treatments during orthodontic moving devices.
  In the treatment of moving orthodontic devices, the patient is more cooperative, and this leads to more patient attention and self confidence.
  An orthodontic mobile plating can also be used even during the evolution of occlusion. Malocclusions, which require simple tpeping movement, can be treated satisfactorily by mobile devices.
  Mobile devices are less visible than fixed devices, but given the recent advancements in fixed devices (such as ceramic brackets and bracket mounting from lingual), this is less important.
  If the wiring is damaged or damaged in the plaque and causes the patient’s pain, the patient can shortly remove the mobile plate until he or she is able to refer to an orthodontist.
  Mobile devices with byteplan can resolve occlusal interactions and lower jaw shifts, which is not possible by fixed devices.

Disadvantages of moving orthodontic appliances

These devices only have uncontrolled tweaking movements and can not be used to perform other movements (body and root movements). For example, in order to pull the first premolar tooth, if a canine can be moved from a mobile plaque, the tooth will have a minor crown inclination from the beginning. In cases where the teeth have a severe rotation, the moving device can not be used except for the central and lateral incisors, with a crown and the possibility of applying force in opposite directions in the crown. Of course, in these cases there is a possibility of shortness or lengthening of the crown length of the teeth.

In abnormal jaw abnormalities, mobile plaques do not have much effect, and often more complex treatments are needed. It is also very difficult to close the remaining spaces with the mobile device. If severe corroditism is severe, the need for a tooth extraction can be made more frustrating with the moving device, as long as the patient has a slight corundum, tooth extraction is also required.

Only with the first premolar tooth extraction can an appropriate contact between the canin and the second premolar be achieved with the mobile device, and in other cases it is not possible to reach the desired contact, and it is often necessary to use fixed devices to complete the treatment.

It is very difficult to supply a lower jaw plaque. In addition, there is little space to put the plain parts. For example, placing fingerprinting conflicts with the language. As a result, the patient is suitable for mobile placement treatment, a disease that has low jaw problems or problems, and only jaw requires treatment, and finally, the use of a mobile plaque is fully dependent on the patient. As a result, it is difficult to achieve the desired result in patients who lack proper co-operation, such as mentally retarded patients. In these cases, if necessary, fixed devices should be used.

*** Orthodontic motion is not prescribed when: The patient is in need of a lack of cooperation or mental retardation.

Ortodontic Movement Plates

As a principle, a desirable result is obtained when appropriate for the treatment of any abnormality of the device. The best results can be obtained by moving orthodontic instruments in the following cases:

• When teeth need only crown tipping movements.
  When a dent with a wide corona needs to correct the rotation.
  To reduce the overbite by using an anterior byte or open-byte treatment with posterior byte planes.
  To remove anterior cross-bytes, increase the overjet and treat class III malocclusion during growth.
  To treat stomach ulcers at the young age.
  For Growth Growth Treatments with Functional Plates.

Prohibitions on the use of mobile orthodontic plates

In patients with class II or III malocclusion, which is prescribed by camouflage, and because of the need for multiple and differential movements in the teeth, treatment with fixed devices is recommended. Also, in patients with high facial height or excessive mandibular angle, fixed devices are preferred because of the need to perform intrusion movements in the teeth. In extreme malformations with excessive bustle of teeth, and when routine dental movements are required to treat abnormalities, it is not recommended to use movable plates. If there are major blemishes in soft tissue such as severe periodontal disorders or the presence of labial fennel located between the root of the teeth, it is better to use orthodontic fixed devices for treatment.

Desirable features of an orthodontic mobile plaque

An orthodontic mobile plaque must have the attribute that excels in the same conditions as constant devices, including the following:

به آسانی ساخته شود.

• It is easy to clean and does not change over time or get stolen.
  Cheap.
  The beauty is acceptable and accepted by the person.
  It is easy to put inside the mouth, making it simple and easy to set up.
  It is biologically difficult and not damaging to the surrounding tissue.
  It is designed to provide less side effects if the patient does not come back to the time.
  It can cause fever in chewing and talking.
  It requires less patient collaboration.

*** With an animated plaque, you can even treat four or five complications simultaneously.

Selection of suitable samples for treatment with mobile devices

• Patient:
  It should be taken into consideration that orthodontic treatment is limited to patients who have good oral hygiene. Trying to treat uncooperative patients or those who use their device as they are trained does not work.It is very difficult to predict how to cooperate with a patient. Bad oral hygiene and lack of care of the teeth indicate no motivation, and you can not start orthodontic treatment unless oral hygiene is maintained and maintained for a few months.
• Occlusion:
• As a matter of principle, the general dentist should not treat the following problem examples:
• Class II and Class III severe skeletal.
  When the angle of the Frankfurt plan to the lower jaw plan (M.A) is very high or very low.
  When complete and extensive treatment for lower jaw arch is required.
  When teeth should be given body movement or when there are multiple dental rotations.
  When the soft tissue is unfavorable, it’s like an incompetent lips.
• It’s obvious that, like all orthodontic treatments, an orthodontist should use mobile devices that anticipate the patient’s aesthetic and functional recovery.
