orthodontic followers are custom-made devices, usually made of wire or clear plastic, which hold the tooth in post-operation position or dental reset method. After the orthodontic treatment phase has been completed to straighten the teeth, there remains a risk of lifelong recurrence (the tendency of the teeth to return to their original position) due to a number of factors: the retreat of the periodontal fibers, the pressure of the surrounding soft tissues, the occlusion and ongoing growth and development of the patient. Using retainers to hold the teeth in their new positions for long periods of time, the surrounding periodontal fibers are allowed to adapt to bone changes that can help minimize changes in the final tooth position after completion of orthodontic treatment.
Followers can be removed or repaired. Four types of followers are usually prescribed by orthodontists and dentists are followers of Hawley, Essix, Zendura, and Bonded (Fixed). Evidence review shows that removable followers are only required to be charged part-time (at night) and that there is still insufficient evidence to recommend one type of storage procedure above another.

Penerima Hawley
The most notable release retainer is the Hawley retainer , which consists of a metal wire that usually surrounds six anterior teeth and keeps them in place. Named for the inventor, Dr. Charles A. Hawley, labial wire, or Hawley arc, incorporating 2 omega loops for adjustment. It is anchored on the acrylic plate that sits on the ceiling (roof of the mouth). The advantage of this type of retainer is that the metal wire can be adjusted to complete the treatment and continue the minor anterior teeth as needed. It is also useful because it is strong and rigid, easily shaped and allows tooth/denture to be added. The main disadvantages of this type of retainer are inferior aesthetics, speech impairment, fracture risk and inferior retention of lower incisors compared to vacuum-shaped retainers.
More recently, a more aesthetic version of Hawley retainer has been developed. For this alternative, the front metal wire is replaced with a clear wire called ASTICS. The retainer is intended to be adapted to the traditional Hawley retainer, which is not practical with a vacuum-shaped follower. The original bow named QCM, was developed to remove the wire display across the surface of the curved face. Excessive damage makes this impractical for younger patients.

Vacuum-formed (Essix) retainer
Another type of detachable retainer is a vacuum-retained builder (VFR). It is a polypropylene or polyvinylchloride (PVC) material, which is more economical and faster to manufacture, typically.020 "or.30" thick. Essix (coined by Dr. John Sheridan) and Zendura are the brand names commonly associated with these followers. This clear or transparent retainer fills the entire dental arch or only from the canines to the canines (clip-on retainer) and is produced from the mold. It's similar in appearance to the Invisalign tray, although the latter is not considered a "follower." Punggawa almost invisible and clear when worn. Therefore, it can provide aesthetic value to the patient. VFR, if used 24 hours per day, does not allow the upper and lower teeth to be touched because the plastic covers the surfaces of chewing teeth. Some orthodontists feel that it is important for surface chewing up and down to meet to allow "favorable settlements" to occur. In addition, it is recommended to wear VFR only at night, every night. When meals are needed, the retainer is removed to allow for natural consumption and to avoid the destruction of VFR. Patients should be told not to drink, especially cariogenic or carbonated drinks, with VFR in situ because it will lead to substantial loss of tooth surfaces and dental caries. The retainer may behave like a reservoir, covering the incisal tip and the cuspal end with a cariogenic drink, causing tooth decalcification. VFR is cheaper, less visible, and easier to use than Hawley's followers; However, for patients with disorders such as bruxism, VFR is susceptible to rapid damage and damage, especially if the material is PVC, short-chain broken molecules much faster than polypropylene, long chain molecules.
Most removable followers come with a retainer box for protection. During the first few days of retainer use, many people experience additional saliva in their mouths. This is natural and because of new objects in the mouth and stimulation due to salivary glands. It may be difficult to speak for a while after gaining followers, but the difficulty of speaking has to disappear over time when someone is used to wearing them.
Followers remain
The entirely different orthodontic categories of followers are fixed or bound followers . There are many different types of retainers, which include:
à · Fiber reinforced
Ã, à · Fixed dogs and dog retainers (only tied to canines)
Ã, à · Multi-strand follower (tied to each tooth)
The most preferred bonded retainer is a multi-strand type stainless steel wire because it is attached to each tooth in the labial segment, using a composite resin or an acid-etching composite bond. For permanent dogs and punggawa dogs, it is only tied to canines and therefore often causes recurrence of incisors; and for fiber reinforced followers, they tend to break generally. To prevent undesirable small tooth movement, the retainer must remain passive.
A fixed retainer usually consists of a passive wire bound to the lingual side (usually, depending on the patient bite, only lower) of the incisors. Unlike the aforementioned retainer type, the retainer still can not be removed by the patient. Some doctors prescribe retainers regularly, especially where active orthodontic treatment has affected major changes in bites and there is a high risk of reversing these changes. While the device is usually required up to one year after the wisdom teeth have been extracted it is often kept in place for life. Retainers can still cause tartar build-ups or gingivitis due to the difficulty of flossing while wearing these retainers. Like braces, patients often have to use yarn switchers to provide dental floss through a small space between the retainer and the teeth.
