How big is your smile? Discover how dental expansion can change your appearance!
In today's orthodontic field, tooth expansion devices, especially jaw expanders, are becoming more and more common. This device is primarily used to expand the upper jaw (maxilla) so that the lower and upper teeth can fit better, thereby improving bite problems. This orthodontic treatment is especially common in children and teenagers ages 8 to 18, and while it can also be used on adults, the dilation process is usually more uncomfortable and takes longer.
Not only does tooth expansion enhance function, it may also significantly improve an individual's confidence and appearance.
Indications of tooth expansion
The use of a jaw expander is indicated when the width difference between the upper and lower jaw is greater than 4 mm. The need for an expansion device can be effectively assessed by measuring the outer width of the upper first molar at the same location on the lower jaw. In addition, jaw expanders are often used to repair cleft lip and palate to allow enough space for the teeth in the upper jaw.
Types of expansion techniques
Rapid jaw expansion
Rapid jaw expansion technology is capable of expanding 0.5 to 1 millimeter per day, usually over a period of 3 to 6 months. This method requires the patient to turn a metal key in the dilator to push the side arms of the dilator to achieve the expansion effect. During this process, the patient may find that there is a gap between the upper and lower front teeth. This phenomenon is relatively common during orthodontic treatment.
Slow expansion
Slow expansion occurs at a slower rate than rapid expansion. Patients need to perform four rotations per week, one millimeter each time, and it usually takes 8 to 10 weeks to achieve the desired effect. Studies have shown that this method creates relatively little tooth space because, while it expands, the tissue surrounding the tooth has a chance to naturally close the space.
Implant-assisted expansion
Implant-assisted rapid jaw expansion technology applies force directly to the jawbone rather than relying solely on the force of the teeth. This technique is particularly useful in young adults with already fused jawbones, providing a less invasive way to achieve jaw expansion. Studies have shown that this expansion is significantly effective in improving upper respiratory tract stenosis.
Surgically assisted rapid jaw expansion
As the patient matures, the development of the jaw leads to fusion of the midpalatal suture, at which time expanders need to be inserted surgically to achieve the desired expansion effect. This usually involves a series of surgeries and is performed under the guidance of an orofacial surgeon.
Side effects and considerations
Patients who use jaw expanders may experience certain side effects, such as difficulty speaking and discomfort such as tingling or pain inside the mouth. These discomforts are normal, and many patients eventually adapt to the use of dilators over time.
The process of tooth expansion may affect your appearance and may even improve your confidence, making it an important treatment option to consider.
History of tooth expansion
The history of tooth expansion techniques dates back to the 19th century, with the earliest records dating back to 1859. Over time, many well-known dentists have researched and improved the expansion technology, gradually developing into the diverse technology it is today.
Finally, tooth expansion not only improves the bite, but also affects a person's smile and self-confidence. Are you ready to smile brighter and face change?
