This study aimed at reporting the clinical case of a frontal bone reconstruction using a customized polymethylmethacrylate (PMMA) prosthesis that after 12 months presented fracture. Male patient, 42 years old, attended the maxilofacial surgery service ambulatory in the General Hospital Roberto Santos (HGRS) in Salvador, Bahia (Brazil), with an esthetic alteration complaint in the frontal region of the face. Patient reported a bicycle accident fours years ago, being submitted to an emergency craniotomy. The proposed treatment was the reconstruction of the frontal bone with customized PMMA prosthesis, constructed from a rapid prototyping biomodel. However, after 12 months postoperatively the patient attended the CTBMF clinic at HGRS reporting fall from height where the physical examination showed fracture of PMMA prosthesis. The cranioplasty is the treatment of craniofacial deformities that promotes morphological and functional rehabilitation of the skull. The craniofacial reconstruction techniques are complex and can be made with autogenous grafts or biomaterials. Among the biomaterials, there is polymethylmethacrylate (PMMA), which is biocompatible, easy handling and have low cost.
