Cranioplasty Welcomes 3D Printed Molds for Reconstructive Surgery in Russia

Cranioplasty is the art and science of repairing defects or deformity in the skull. The reasons to perform this type of delicate surgery range from traumatic injuries to surgeries to birth defects.

Dr. Ivan Ulianovsky of the Vologda region in Russia was approached by neurosurgeons at the Vologda Regional Hospital for assistance in the creation of a mold for a cranial implant. The implant was required for a patient who had extensive defects in his skull as the result of a traumatic injury.

In many cases, the material of choice for implants for skull injuries is titanium. Titanium is a suitable material because of its strength, biocompatibility, and low rates of post-surgical infection. However, Dr. Ulianovsky was of the opinion that in an injury such as this one, resulting in the loss of such a large portion of the skull, that titanium would not be ideal because of its potential for deformation when covering such a large expanse. Instead, he wanted to use Protakril-M, a cold-cure acrylic powder that is often used in dental practice for the creation of dentures and orthodontic appliances, among other things. … (read more)
