Larger cranial bone defects can cause cranial disfigurement as well as potential mechanical brain trauma. Conventionally pre-fabricated acrylic cranioplasty implants require complicated procedures and result in potential dimensional and contour inaccuracies. The development of stereolithographic techniques for generating acrylic resin skull models allows the pre-fabrication of custom acrylic resin cranial implants with greater clinical predictability.
Cranial bone defects can be a result of trauma, congenital defects, infection or iatrogenically induced by surgery. Even for patients with sufficient hair to cover the affected site, hair styling may not be sufficient to mask off the deficient external cranial contour.
