A. Growth factor delivery via an injectable system to stimulate regeneration of the cartilaginous articular disc of the temporomandibular joint. B. Cell transplantation of salivary gland cells on polymer scaffolds to restore a functionally deficient salivary gland. C. Combined approach of cell transplantation and growth factor delivery for bone regeneration using a growth factor-releasing scaffold as a cell carrier for osteo-progenitor cells. D. Gene therapy approach employed to regenerate the periodontium of a periodontal defect resulting from periodontal disease. E. Cell therapy approach using bone precursor cells as an autogenous bone graft to enable the placement of dental implants in an area that is commonly deficient in bone (below the maxillary sinus).
