Impact of disc displacement on adolescent dento-maxillofacial morphology

doi:10.7518/hxkq.2026.2025363

Abstract

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.

Key words: adolescent, temporomandibular disorder, disc displacement, condyle resorption, dento-maxillofacial deformity
