PENON VIVAS, Pedro Angel; SARRACENT PEREZ, Humberto    MOREIRA RODRIGUEZ, Patricia. Temporomandibular joint replacement because of odontogenic keratocyst. []. , 50, 1, pp. 109-118. ISSN 0034-7507.

Temporomandibular joint replacement is required in a variety of conditions. Among the most frequent are ankylosis, osteoarthrosis, advanced stages of the temporomandibular dysfunction syndrome, post-traumatic joint damage, and neoplastic or tumoral processes. Odontogenic keratocysts, which are classified as developmental odontogenic cysts for study purposes, constitute 7-10 per cent of all maxillomandibular cysts. Two peaks have been identified in their incidence: between the second and third decades of life, and between 50 and 60 years of age, with a slight predominance of the male sex. They are most common in the third molar area of the mandibule, with expansion to the ascending branch. A case is presented of a male 57-year-old patient requiring temporomandibular joint replacement due to an odontogenic keratocyst involving the entire right mandibular branch, including the condylar and coronoid processes, as well as the angle as far as the posterior third of the mandibular body. One year after surgery, the patient's evolution was satisfactory.
