Facial Regeneration - Calvaria and Upper Face
Devastating facial injuries require many approaches to restore bone and soft tissues. In this project, investigators are designing and developing physiological, biocompatible, and biodegradable implants for reconstruction of large bone defects in the cranio-orbital, or upper bone region of the face.
Through this project RCCC researchers will fabricate a porous, injectable and implantable system that will promote regeneration of bones in the upper face after injuries to the head and face. The system will be made of biocompatible composites that deliver complementary antibiotics, and agents that promote growth of blood supply and bone -- either alone or in combination. We anticipate initial pre-clinical trials with the best performers of these materials to commence within 48 months of project initiation.

Facial Regeneration- Mid Face (Maxillary Complex) and Lower Face (Mandibular Complex)
In the mid and lower face, unlike the upper face, the bone must bear weight. This adds mechanical requirements for selection of the structural material and fabrication of its shape. In this project, RCCC researchers are designing composite weight-bearing injectables and implants that promote enhanced regeneration of bone for mid-face and lower-face defects. The system will be made of biocompatible composites that deliver suitable and complementary antibiotics and factors that promote blood supply and bone growth either alone or in combination. These composites will also be mechanically competent, able to regenerate bone, and promote the formation of blood vessels. We anticipate initial pre-clinical animal trials with the best performers of these materials to commence within 48 months of project initiation for mid-face and 54 months for lower face and mandible.
