This paper reports a case of habitual temporomandibular dislocation which was surgically treated using a T-type titanium miniplate. A 53-year-old man visited our hospital presenting with recurrent frontal dislocation of both temporomandibular joints and he had severe mental retardation. Following a standard preauricular approach to the zygomatic arch, a bent T-type titanium miniplate was applied to limit the movement of the condylar process. The plate was fixed to the zygomatic arch with three 2-mm titanium screws. Routine follow-up, 1year and 6months after surgery, showed no clinical evidence of recurrent dislocation. This method seems to be very useful for patients with mental disturbances, because it is easy to perform and requires no intermaxillary fixation postoperatively.
