Adults in Houston with narrow upper jaws who were previously told their only option was invasive jaw surgery may now have a less invasive alternative. Mia Orthodontics, a practice led by board-certified orthodontist Dr. Alireza Hourfar, is conducting evaluations for miniscrew-assisted rapid palatal expansion (MARPE), a technique designed to widen the upper jaw in patients whose mid-palatal suture has already fused—a condition that typically emerges in late adolescence and adulthood. The announcement matters because it expands the range of orthodontic treatments available to adults who might otherwise face orthognathic surgery, a major procedure that involves cutting and repositioning the jaw bones.
Unlike conventional palate expanders used in growing children, MARPE palate expanders in Houston TX are anchored directly to the palate using small titanium miniscrews, also known as 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. According to the practice, the miniscrews distribute the expansion load in a way that makes it possible to separate a palate seam that has already closed—something conventional expanders cannot reliably achieve in adults.
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, where the upper back teeth sit inside the lower teeth; 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 at Mia Orthodontics 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 broader implication is that more adults may be able to avoid the risks, recovery time, and cost associated with jaw surgery. As the population ages and more adults seek orthodontic correction, approaches like MARPE could become an increasingly important tool in the orthodontist's arsenal.
