The aim of this paper is to present the two cases with extensive ameloblastomas of the mandible requiring immediate reconstruction. Patients with mandibular ameloblastomas diagnosed histopathologically were treated in Kingston Public Hospital Jamaica with segmental mandibulectomy and immediate reconstruction with iliac crest bone graft and reconstruction plates. Mechanical stability was adequately achieved by the use of 2.7 mm thick titanium reconstruction plates and bicortical screw osteosynthesis which should be removed 6 months–1 year later in order to allow the bone to heal along biomechanical principles. The two patients presented in this paper are male with the age of 24 and 38. Both patients recovered well. The facial nerve was not affected in any patient treated extra orally. The functional and esthetic results are satisfactory for the patients.
