Abstract:
Disc displacement (DD) is the primary type of temporomandibular disorder. Adolescence marks a period of high incidence for DD and is also a critical phase for dentofacial development. There is a strong correlation between DD and condyle size, ramus height, mandibular morphology and position. However, whether they are directly related, whether DD can cause or exacerbate dento-maxillofacial deformities, and the degree of association between different types of DD and adolescent craniofacial development remain inconclusive. This research reviews the abovementioned issues to deepen the understanding of the potential impact of DD on dento-maxillofacial development during adolescence. The aim is to offer comprehensive clinical recommendations for the etiological mechanisms, clinical diagnosis, and treatment planning of dento-maxillofacial deformities.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
