dc.description.abstract | PURPOSETissue engineering solutions focused on the temporomandibular joint (TMJ) have expanded in number and variety over the past decade to address the treatment of TMJ disorders. The existing literature on approaches for healing small defects in the TMJ condylar cartilage and subchondral bone, however, is sparse. The purpose of this study was thus to evaluate the performance of a novel gradient-based scaffolding approach to regenerate osteochondral defects in the rabbit mandibular condyle. MATERIALS AND METHODSMiniature bioactive plugs for regeneration of small mandibular condylar defects in New Zealand White rabbits were fabricated. The plugs were constructed from poly(D,L-lactic-co-glycolic acid) (PLGA) microspheres with a gradient transition between cartilage-promoting and bone-promoting growth factors. RESULTSAt six weeks of healing, results suggested that the implants provided support for the neo-synthesized tissue as evidenced by histology and 9.4T magnetic resonance imaging. CONCLUSIONThe inclusion of bioactive factors in a gradient-based scaffolding design is a promising new treatment strategy for focal defect repair in the TMJ. | en_US |
