Many people think that the braces process only begins when the doctor attaches the braces or delivers the clear braces tray. In fact, from the orthodontist's perspective, that is just the tooth movement stage. In order for teeth to move in the right direction, within biological limits, and achieve stable long-term results, patients often have to go through a preparation stage calledpre-orthodontics.
This is the treatment step that acts as the "foundation" of the entire orthodontic plan. If the foundation is not well prepared, moving teeth will be more difficult, treatment time will be longer and the risk of relapse after braces are removed is also higher. Therefore, at large orthodontic centers around the world, doctors often spend a lot of time evaluating, planning and treating existing problems before officially starting braces.
Pre-orthodontic treatment is a comprehensive preparation stage for teeth, jawbone, periodontal tissue and the function of the chewing system before moving teeth with braces or trays. The goal of this stage is not to immediately straighten teeth but to create a favorable biological environment for the orthodontic process to take place safely, effectively and achieve optimal results.
Contrary to what many people think, pre-orthodontics is not a single technique but a treatment strategy. Depending on each patient, the doctor may prescribe one or more different measures such as treating tooth decay, controlling periodontitis, expanding the jaw, maintaining space after premature loss of baby teeth, guiding teeth to grow in the right position or using functional appliances to adjust the growth of the jaw bone.
According to the recommendations of theAmerican Association of Orthodontists, children should have their first orthodontic examinationno later than 7 years old. The purpose of this examination is not to get braces right away but to detect abnormalities in jaw bone growth, bite and tooth growth direction early while there is still a chance for effective intervention. Many cases, if treated in the pre-orthodontic stage, can significantly reduce the complexity of the braces process later, even limiting the need for tooth extraction or orthognathic surgery. This has been recognized by the AAO and many clinical studies in current treatment guidelines.
To understand why pre-orthodontics is important, it is first necessary to understand the mechanism of tooth movement.
Teeth do not "slide" in the bone as many people think. When an appropriate orthodontic force is applied, the periodontal ligament will be compressed on one side and stretched on the opposite side. This process stimulates bone-resorbing cells (osteoclasts) to resorb bone in areas under pressure, while bone-forming cells (osteoblasts) form new bone in areas under tension. Thanks to this continuous bone restructuring phenomenon, teeth can move to the desired position.
However, the above mechanism only takes place smoothly when the alveolar bone, periodontal tissue and bite are all in a healthy state. If the jaw is too narrow, the alveolar bone is too thin or the patient is suffering from periodontitis, moving the teeth will increase the risk of bone loss, gum recession, tooth root loss or cause the teeth to move outside the alveolar bone limits. This is the reason why doctors should not rush to attach braces as soon as the patient comes for examination, but need to fully evaluate biological factors before planning treatment.
It can be said that pre-orthodontics is the process of creating conditions for orthodontic forces to be most effective, while minimizing complications that may occur during treatment.
Although the pre-orthodontic plan may be different for each patient, they are the same. towards four important goals.
First of all,create enough space for teeth to align. Tooth crowding occurs when the total size of the teeth is greater than the length of the jaw. If more space is not created before braces, the doctor will be forced to move the tooth beyond the biological limit or use too much force, increasing the risk of root resorption and instability after treatment. Depending on the case, space can be created by jaw expansion, dental arch expansion, interproximal grinding (IPR) or tooth extraction as indicated.
The second goal is tobuild a healthy bone base and periodontal tissue. A patient who is suffering from gingivitis, periodontitis or has many decayed teeth will not be an ideal candidate for immediate braces. According to the principles of orthodontic treatment, all inflammatory diseases need to be controlled before starting orthodontic force to limit the risk of loss of adhesion around the teeth and alveolar bone loss.
In addition, pre-orthodontics also helps toeliminate factors that cause recurrence. In clinical practice, there are many cases of teeth falling back after braces are removed even though the patient still wears the retainer according to instructions. The cause may come from functional habits such as tongue thrusting, mouth breathing, lip biting or thumb sucking. If these factors are not adjusted, the force from the lips, cheeks and tongue will continuously change the position of the teeth, making orthodontic results difficult to maintain long-term.
Finally, pre-orthodontics helpsreduce the difficulty of the entire treatment. Especially in children, intervention at the right time can take advantage of the natural development of the jaw bone to correct malocclusion. This is an advantage that adult patients no longer have. Therefore, in many cases, if treated early, only simple braces are needed, while if delayed until the bone has fully developed, orthognathic surgery may be required.
Not all patients need to undergo pre-orthodontics. However, in clinical practice, doctors often consider indications for groups at high risk of having difficulty during the braces process.
First,children are in the period of tooth replacementwith signs of jaw narrowing, crossbite, premature crowding or loss of baby teeth before the physiological time. This group of patients has many advantages because the jawbone is still developing, allowing doctors to intervene with orthopedic devices to guide the development of the jaw and create conditions for permanent teeth to grow in the correct position.
The second group isadults with moderate to severe tooth crowding, especially when X-rays show thin alveolar bone or insufficient space on the jaw to align the teeth. These cases often need to create space before attaching braces to ensure teeth move within safe biological limits.
In addition,patients with periodontal diseases or many teeth that need treatmentIt is also necessary to complete the pre-orthodontic phase before starting braces. Controlling infection, restoring decayed teeth and stabilizing periodontal tissue not only helps the tooth movement process go more smoothly but also contributes to protecting long-term oral health.
It can be seen that pre-orthodontics is not a treatment step reserved for children but is an important part of the orthodontic plan of many different patient groups. Whether or not pre-orthodontics is needed depends on the results of the examination, X-ray analysis, jaw model and comprehensive assessment by the orthodontist.
When mentioning pre-orthodontics, most people immediately think of jaw expanders. In fact, jaw expanders are just one of many types of instruments used by orthodontists in the preparation stage before braces. Each appliance is designed to address a specific problem with the jawbone, dental arch or oral muscle function. Choosing which appliance depends entirely on the cause of the malocclusion, not the patient's wishes.
