Treatment of patients with maxillofacial defects is one of the most challenging tasks. Prosthetic reconstruction of maxillomandibular defects may be achieved with the help of removable and fixed prosthesis to restore the lost form, function and speech. The purpose of this article is to describes a case of CEOT (Calcifying Epithelial Odontogenic Tumor) in left mandibular body region managed with a treatment obturator, which allowed closure of the defect by secondary healing through granulation tissue maturation and associated bone fill. A 19 guage wire was used to stabilize the appliance, and provide retentive properties. The obturator allowed decrease in size of defect and enhanced comfort and overall wellbeing of the patient.
