title: Using bone cement for surgical treatment of bilateral osseous temporomandibular joint ankylosis.
abstract: Temporomandibular joint (TMJ) ankylosis with complete immobility of lower jaw represents a maximal functional impairment and causes malocclusion and impaired function of mastication. Main goal of surgical treatment of patients with TMJ ankylosis is regaining of organ function and good cosmetic results. Authors modified the implant of articular head by bone cement for surgical treatment of TMJ ankylosis (five cases). Mandibular arch osteotomy on both sides was performed under nasotracheal anesthesia. 1.5-2 cm bone conglomerate was removed and articular fossa was formed in remaining part. Titan mini plate was formed so that it was possible to hang it on osteotomized surface of the arch. Free surface of plate was faced towards the artificial articular fossa, on which the articular head was formed using bone cement. The plate on the other side was fixed on mandibular arch with screws. All cases were followed by good cosmetic and functional effect (period of observation 5 month-4 years). The method, despite of small material size is advantageous due to its good outcome, low cost and relatively simple surgical technique.
