Prosthetic Rehabilitation of Bilateral Cranial Defects: A Case Report

Case Report Abstract Cranial defects may result from trauma, disease, and congenital malformations. Repair of cranial defects is indicated to protect underlying brain tissue, provide pain relief at the defect site, improve cosmesis, and minimize patient anxiety. Cranioplasty is accomplished either with osteoplastic reconstruction or restoration with alloplastic implants. Cranial alloplastic implant materials used include metal, acrylic resin, polyethylene, and silicone. As an ever increasing number of expensive biomaterials for bone replacement have become available PMMA remains a cheap and readily available option that is potentially under used. There are no long term studies or case series published with the use of heat cure PMMA to the best of our knowledge. This case report describes the rehabilitation of a cranial defect using heat cure polymethacrylate resin with a novel impression technique to develop the external contour of the defect using modelling clay.
