Reconstruction of a cranial defect with an alloplastic implant

Cranial defects occur most frequently during wartime, but their incidence during peace time, as a result of accident or disease, makes knowledge of cranioplasty useful to the interested practitioner. Trauma accounts for most of the cranial defects. Numerous materials have been historically employed for the restoration of cranial defects. Heat-polymerized methyl methacrylate alloplastic cranial implant requires presurgical fabrication of the implants. It facilitates the reproduction of the contours, and the tissue bed is not exposed to the heat of polymerization or to the free monomer. In this study, a case report has been presented in which heat-cured acrylic resin alloplastic implant has been fabricated for a patient with left frontal bone defect.
