Patient Specific Plates

In osteotomies of the maxillofacial region, including Lefort, BSSO, cheek osteotomies, genioplasty, and jaw segmental osteotomies, the simulation of osteotomies and the design of custom plates support the surgeon in controlling and fixating bone segments more easily.

For designing custom plates, a cutting guide is created first, embedding the incision paths and drill hole locations. Then, the osteotomies are simulated, and the bone segments are positioned based on the surgeon’s treatment plan and computer analysis. The custom plate is designed according to the final positions of the bone segments.

These plates are manufactured using 3D titanium printers. After printing and undergoing finishing processes, they are anodized. The anodizing process creates an oxide layer on the prosthesis surface, preventing the release of metal ions. The micro-tubular structure of the oxide layer significantly aids in the osteointegration process. Additionally, anodizing enables color-coding for multi-piece prostheses and helps to mask the dark titanium color in subperiosteal prostheses that sit under the gums, ensuring that the titanium’s dark hue is not visible in the patient’s mouth.
