Orthodontic appliances: know the differences and their indications
The first questions that patients ask when they enter the orthodontist's office are: "Will I use a device? When? Fixed or mobile? Can I choose the color?". After installation and after the news, the next question is: "When will I take the devices?" In order to try to kill this curiosity, I present here a little of the orthodontic universe.
The devices can be divided into two groups: removable and fixed. The removable ones are embedded in the mouth, being able to be removed by the patient or orthodontist, and depend on the collaboration of the patient. They can be orthodontic - that perform small dental movements -, or orthopedic, used in the corrections of bone alterations of growth. The latter are placed in children and adolescents during the growth phase, inhibiting or stimulating the development of bones, or even redirecting an unfavorable growth trend. To be effective they should be used for the most hours per day.
Fixed appliances are used when moving teeth into the bone. They are composed of brackets that can be metallic, plastic or porcelain, which support the metal arch. With the use of fixed appliances, better meshing between the upper and lower teeth is achieved, restoring a balanced smile.
It is very difficult to predict how long a treatment lasts
Each device has a precise indication and who will determine which the best type and how long treatment is the patient's dental arch. Each case is a case and each device is designed and designed to correct that case in the best way and in the shortest possible time.
Today, the number of adult patients seeking the orthodontist is very large and usually the best indication in the most cases is the fixed appliance for more effective tooth movement. Removable appliances move the teeth more slowly and very slowly. Orthopedic appliances are contraindicated at this stage, as growth is over.
For adults who deal with the public and do not want the metallic option, there are aesthetic and invisible options. There are devices such as polycarbonate, sapphire or porcelain, which are quite aesthetic, in which the support parts are mixed with tooth coloration - however, these devices have two drawbacks. The first is that because of the friction of the ceramic with steel wire, these appliances are less efficient and can increase the duration of treatment. The second disadvantage is that it has a much higher cost than conventional steel fixed appliances.
There is also the lingual technique where the parts are glued on the inside of the teeth and has as main disadvantage the nuisance to the tongue. We can still cite a series of molds that promote the correct alignment and leveling of the teeth.
It is very difficult to predict how long a treatment lasts, because it depends on several factors such as biological response of the organism, type of malocclusion, type of indicated device and patient collaboration . The important thing is to find a qualified professional, use the indicated appliance in the best way possible and attend the monthly maintenance queries for activation and control.
A new study conducted by researchers at Columbia University suggests that dental consultations provide an opportunity for dentists to identify patients with diabetes or pre-diabetes who were unaware of this problem "Periodontal disease is an early complication of diabetes, and about 70 percent of US adults see a dentist at least once a year," says Dr.

- Scholars of the Institute of Technology Massachusetts, in Cambridge, United States came to this conclusion after a study done in mice, where clusters of amyloid proteins were developed and they eventually lost their memory, just as it does with humans with Alzheimer's. To verify this, the scientists placed a box that shocked the mice. While the mice in the control group learned to fear the box, those with the disease continued to go to it.
