L’articolazione temporo-mandibolare in dentatura decidua e mista : revisione della letteratura

Objectives. Aim of this work is to provide a detailed description of the development of the temporomandibular joint (TMJ) in primary and mixed dentition. Methods. The most important joint structures (condyle, glenoid fossa, articular eminence, articular disk and articular capsule) are analyzed separately in relation to histomorphology at birth and during the following stages of maturation and development. Results. During growth the glenoid fossa acquires its characteristic S shape and a tubercle develops. The articular eminence height grows at a very high rate until the age of seven (the period of primary dentition), almost stops until the age of eleven (the period of mixed dentition) and reaches its full height by the age of 20. Conclusions. The knowledge of TMJ evolution during craniofacial growth could help to establish more biological treatment modalities.
