Orthodontic expanders are commonly associated with children and adolescents, but advancements in orthodontic technology have made upper jaw expansion a viable option for adults as well. For those experiencing issues such as crossbite, upper jaw constriction, or dental crowding, adult orthodontic expanders can offer effective solutions.
Understanding Adult Palatal Expanders
A palate expander for adults is a custom-fitted orthodontic device designed to widen the upper jaw (maxilla). Unlike traditional expanders used in younger patients, adult treatments often require specialized appliances due to the increased rigidity of mature bone structures.
MARPE: A Non-Surgical Solution
One innovative approach is the Miniscrew-Assisted Rapid Palatal Expander (MARPE). This device uses Temporary Anchorage Devices (TADs)—small orthodontic screws inserted into the palate—to provide a stable anchor for expansion. By applying gentle, consistent pressure, the MARPE facilitates the separation and widening of the palatal bones, effectively expanding the upper jaw without the need for surgical intervention. This method has shown significant success in adults, offering a less invasive alternative to traditional surgical procedures.

SARPE: Surgically Assisted Rapid Palatal Expansion in Orthodontics
Surgically Assisted Rapid Palatal Expansion (SARPE) is another way to expand the upper jaw in an adult patient. A SARPE is a combination orthodontic and oral surgery procedure designed for adults who require significant widening of the upper jaw, but their palate suture is too tight too expand. The procedure involves surgery to create a cut along the midline of the maxilla to loosen the bone, followed by the use of a Rapid Palatal Expander (RPE) to gradually widen the palate over several weeks. This type of expansion protocol for adults is much more invasive than MARPE. It involves an oral surgeon and a recovery period after the jaw surgery.
Three-Piece LeFort I: A Surgical Approach to Jaw Expansion
The Three-Piece LeFort I Osteotomy is a highly effective surgical procedure for widening a narrow upper jaw that also needs additional jaw movement. This procedure is designed to expand the upper jaw when other surgical correction of the upper jaw is need such as overbite and underbite corrections in adults.
Benefits of Jaw Expansion in Adults
Utilizing a jaw expander for adults can address several orthodontic concerns:
- Crossbite Correction: A crossbite occurs when the upper teeth bite inside the lower teeth. Expanding the upper jaw aligns the dental arches properly, resolving this misalignment.
- Alleviating Dental Crowding: Limited space in the dental arch can lead to overcrowded or misaligned teeth. Expansion creates additional room, facilitating proper tooth alignment and potentially reducing the need for extractions.
- Improved Breathing and Sleep Quality: Some recent studies have shown improved nasal airway measurements after expansion of a narrow upper jaw (maxilla). While this is not the primary indication of doing a MARPE, expansion here can benefit a constricted nasal airway. At your consultation, we may discuss additional referrals such as to an ENT if nasal breathing or sleep apnea is an issue for you. Maxillary expansion can enhance nasal airflow, potentially improving issues like obstructive sleep apnea. American Association of Orthodontists
Considerations for Adult Patients
While adult orthodontic expanders offer promising results, it’s essential to consult with an experienced orthodontist to determine the most appropriate treatment plan. Factors such as bone density, overall oral health, and specific orthodontic needs will influence the choice of expander and the treatment’s success.
In conclusion, advancements like MARPE and TAD expanders have expanded the horizons of orthodontic treatment for adults. By addressing issues like crossbite, dental crowding, and airway constriction, these devices contribute to improved oral health and overall well-being.
