maxillary deficiency: Definition, Uses, and Clinical Overview
maxillary deficiency is a condition where the upper jaw (the maxilla) is smaller, positioned too far back, or narrower than expected relative to the rest of the face. It can affect how the upper and lower teeth fit together (occlusion) and how the midface looks in profile. Dentists and orthodontists commonly use the term when evaluating bite problems such as underbites and crossbites. It is discussed in orthodontics, craniofacial care (including cleft care), and orthognathic (jaw) surgery planning.
