CADskills, a medical device startup from Belgium uses 3D Printing Technology to produce patient-specific implants for craniomaxillofacial (CMF) and neurosurgery patients, including its innovative AMSJI, a new generation of subperiosteal implant for extreme maxillary atrophy. To counter bone atrophy, AMSJI eliminates the bone grafting process and its months of recovery time and the surgery takes around 1 hour. These Titanium implants are 3D Printed using Mimics Innovation Suite (MIS) from Materialise.
