Abstract
A method of designing a craniomaxillofacial implant that is a rigid plate of substantially uniform thickness, including: positioning a surface element of the plate as a departure from a reference location within a base outline, the departure being represented by a fraction of the length of a normal path projected from the reference location to a predetermined soft tissue layer at a supported location within an anatomic region of interest, and the fraction being based upon a required patient-specific support at the supported location.

A method of designing a craniomaxillofacial implant that is a rigid plate of substantially uniform thickness, the method comprising positioning a surface element of the plate as a departure from a reference location within a base outline, the departure being represented by a fraction of the length of a normal path projected from the reference location to a predetermined soft tissue layer at a supported location within an anatomic region of interest, and the fraction being based upon a required patient-specific support at the supported location.
A patient-specific craniomaxillofacial implant formed into a plate that is rigid, warped, and of a substantially uniform thickness, wherein the warpage is configured preoperatively so as to adapt the implant to—
- be set onto and supported by at least a craniomaxillofacial bone and/or a soft tissue layer overlaying the craniomaxillofacial bone;
- and
- support the soft tissue layer in place of at least the craniomaxillofacial bone, thereby compensating or augmenting the elevation of the soft tissue layer.
