In the previous article, we discussed that there are many children who have issues with "narrow dental arches." A narrow dental arch can lead to various oral problems and significantly impact a child's future oral and jawbone development. By utilizing a palate expander (maxillary expander) under the guidance of a dentist during this critical growth period, effective arch expansion can be achieved. So, what exactly is a palate expander? What types are there? What benefits does expansion bring?
Different types of expanders
The palatal expansion treatment involves using orthodontic devices to widen the upper jaw, effectively enlarging the dental arch. These devices are known as "expanders." They can be broadly classified into two categories: fixed and removable.
Fixed palatal expanders
- Implant-supported palatal expanders:This type of expander requires the dentist to implant four mini dental implants into the patient's upper jaw. The implants provide stable support for the expansion of the maxilla. This design ensures a more stable and effective expansion process, making it suitable for older adolescents and adults as well.
- Rapid palatal expanders:This expander is installed in the upper jaw and connects to the molars on both sides for added stability. It features a screw mechanism that the patient must turn daily with a provided key, as directed by the dentist. This tension gradually widens the dental arch, making it a relatively quick and effective expansion device.
Removable palatal expanders
If the required expansion is not significant, the dentist may recommend a removable expander. There are various styles available, such as the traditional removable expander made of stainless steel and clear acrylic, which also requires the patient to turn a screw daily. Additionally, there are newer options like the clear aligner expanders (Invisalign) that use 3D printing technology and are made from nylon. Patients simply need to follow the dentist's instructions to regularly switch to the next expander to effectively expand the arch. However, to achieve the desired results, patients must wear removable expanders for sufficient time.
Benefits of palate expanders
A narrow dental arch can prevent permanent teeth from having enough space to emerge properly. Receiving palatal expansion treatment during the critical period of tooth transition and bone development can effectively help with teeth alignment, creating more space for proper arrangement. This not only reduces the complexity of future orthodontic work but also decreases the likelihood of needing tooth extractions later on. Furthermore, patients with a narrow upper arch often experience bite problems; undergoing expansion treatment in conjunction with orthodontic procedures can minimize occlusal interference.
In summary, palatal expansion offers numerous benefits. As mentioned in the previous article, a narrow dental arch can lead to many future oral and jaw development issues for children. Early consultation with a dentist to take advantage of this critical period for treatment can have a profound impact on a child's future.
