Adults in Houston with narrow upper jaws and fused palates may have a new nonsurgical option for structural correction. Mia Orthodontics, led by board-certified orthodontist Dr. Alireza Hourfar, is now offering miniscrew-assisted rapid palatal expansion (MARPE) to patients whose mid-palatal suture has already closed—a condition that traditionally required jaw surgery to address.
The practice, located at 3636 Greenbriar Dr. Ste A-101, is conducting evaluations for adults with narrow palates, crossbite, crowding, or airway concerns who may be candidates for the device. 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 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 differ from traditional appliances. The miniscrews distribute the 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 involves assessing skeletal development, the degree of palatal fusion, and the specific bite relationship. Not every adult will be a suitable candidate; the evaluation determines whether MARPE is appropriate 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, 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 means the practice regularly works through these case-specific determinations with patients who were not candidates for simpler appliances earlier in life.
