A narrow upper jaw, also called maxillary transverse deficiency, reduces the space available for the teeth to fit and can have profound effects on nasal and sleep breathing. Although some maxillas are narrow due to genetics, mouth breathing also plays a significant role. A narrow maxilla will often appear v-shaped, with a high-arched palate, and with dental crowding.
Dr. Coppelson achieves expansion of the maxilla using a Maxillary Skeletal Expander, a type of Miniscrew-assisted rapid palatal expander (MARPE) developed by Dr. Won Moon. This, in combination with minimally invasive surgical techniques, allows predictable and profound expansion of the upper jaw and the nasal airway.
