Aim: The aim of the present article was to describe use of chin bone graft to increase articular eminence as preferred treatment for mandibular chronic luxation. Patients and methods: The present study was undertaken with 12 patients, average age 44 years. Patients had been diagnosed as suffering from chronic mandibular luxation (dislocation), with pain symptomatology rating 8 or more in the Analogous Visual Scale (AVS). Patients had experienced an average 1.5 year evolution and 55 mm or more oral opening. Patients had been conservatively treated for at least three months, with no visible improvement. Patients were then treated following a modified Norman technique, in which an articular eminence augmentation is performed with a chin bone graft placed through pre-auricular approach. Results: None of the patients presented new dislocation events during the 18 month follow up period after surgery. Conclusions: The present study showed the fact that mandibular chronic dislocation correction with placement of pre-condylar stop with chin bone graft is an effective and safe technique.
