What is hypoplasia of the maxilla?

What is hypoplasia of the maxilla?

Maxillary hypoplasia, which is also called maxillary deficiency, is the underdevelopment of bones in the upper jaw. This condition produces midfacial retrusion and creates the appearance of protuberance where the lower jaw juts forward.

What is a small maxilla?

Definition. Abnormally small dimension of the Maxilla. Usually creating a malocclusion or malalignment between the upper and lower teeth or resulting in a deficient amount of projection of the base of the nose and lower midface region. [

What is maxillary asymmetry?

Abstract. Vertical maxillary asymmetry (VMA) is a condition characterized by distinct morphologic features: dentoalveolar asymmetry, canted nasal floor and occlusal plane, and asymmetric lip elevation.

What causes small upper jaw?

In the vast majority of cases, it can simply be due to heredity, when other family members are faced with the same problem. In most cases, the misalignment is due to an upper jaw that is too small or too narrow in relation to the lower jaw. Indeed, it is more rare to see a normal upper jaw with an oversized lower jaw.

Is maxillary hypoplasia congenital?

What causes maxillary asymmetry?

There are several causes of asymmetry such as genetic defects in mechanisms, which induce symmetry, and also environmental factors. Trauma is one of the causes of asymmetry. Untreated mandibular fracture may lead to different degrees of asymmetry.

What is facial hypoplasia?

Midface hypoplasia describes a situation in which the upper jaw, cheekbones and eye sockets have not grown as much as the rest of the face. Because of this, the eyes can seem large, appearing bulgy or “bug-eyed.” Also, the upper teeth usually do not meet the lower teeth well and result in an “under bite” appearance.

At what age does the maxilla stop growing?

Vertically, the maxilla is 67.3% of its adult size at age 1 year and reaches 82.2% by the age 5 years [23]. This portion of the maxilla grows on average around 24 mm between the ages of 1 to 18 years; 33% of this growth is complete at the age of 3 years and 54.9% of its growth is after age 5 years [7,23].

What is maxillary osteotomy?

Maxillary Osteotomy: The operation is undertaken through an incision made in the gum above the teeth in the upper jaw. There are no incisions made on the face. The upper jaw is then cut with a small saw to allow it to be broken in a controlled manner.
