Houston Orthodontist Offers MARPE Palate Expansion for Adults, Avoiding Jaw Surgery

Adults in Houston with narrow upper jaws, crossbites, or airway concerns may have a new alternative to invasive jaw surgery. Mia Orthodontics, a practice led by board-certified orthodontist Dr. Alireza Hourfar, is now offering miniscrew-assisted rapid palatal expansion (MARPE) to adult patients whose mid-palatal suture has already fused—a condition that traditionally left orthognathic surgery as the primary structural option.

Unlike conventional palate expanders designed for growing children, MARPE palate expanders in Houston TX are engineered specifically to address the fused suture found in older teenagers and adults. The device is anchored directly to the palate using small titanium miniscrews, also called temporary anchorage devices (TADs). These miniscrews allow the expander to apply force precisely at the suture, gradually widening the upper jaw over a prescribed period. Because the hardware is fixed to bone rather than resting against soft tissue or teeth alone, the expansion mechanics work differently than traditional appliances, making it possible to separate a palate seam that has already closed.

Dr. Hourfar evaluates patients for MARPE when clinical findings point to a structurally narrow upper jaw as the underlying issue. Common presentations include a posterior crossbite, significant dental crowding that stems from insufficient arch width rather than tooth size alone, and in some cases, concerns about nasal airway narrowing that may relate to jaw structure. The evaluation involves an assessment of skeletal development, the degree of palatal fusion, and the specific bite relationship. Not every adult with these presentations will be a suitable candidate—the evaluation determines whether MARPE is an appropriate path or whether other approaches better fit the patient's clinical picture.

The use of temporary anchorage devices at Mia Orthodontics extends beyond palatal expansion. Mini implant assisted orthodontics in Houston TX encompasses a range of tooth movement applications where TADs serve as fixed anchorage points, enabling movements that would otherwise require patient compliance with headgear or could cause unintended shifting of anchor teeth. In the context of MARPE specifically, the miniscrews are placed in the palate under local anesthesia and are removed once expansion is complete.

For adults who have been told their bite issues require orthognathic surgery, an evaluation for MARPE may clarify whether a surgical approach is necessary or whether skeletal expansion through mini implant assisted orthodontics can address the structural component of treatment. Dr. Hourfar's role as an orthodontist for adults in Houston means the practice regularly works through these case-specific determinations with patients who were not candidates for simpler appliances earlier in life.

The implications for Texas adults are significant. Jaw surgery typically involves hospitalization, weeks of recovery, and risks associated with general anesthesia. MARPE, by contrast, is performed in an office setting with local anesthesia and offers a less invasive path to correct skeletal narrowing. For patients suffering from chronic nasal obstruction, dental crowding, or bite misalignment, this approach could improve quality of life and reduce health care costs. As more adults seek orthodontic solutions that fit their busy lifestyles, practices like Mia Orthodontics are expanding the options available. Learn more about the practice at Mia Orthodontics.
