Such approaches often seek to leverage bioresorbable scaffold materials to mitigate potential complications that might be associated with long-term retention of the implanted material.
Tissue engineering scaffolds increasingly seek to mimic complex biomolecular and mechanical gradients reflective of the tissue(s) of interest to guide regeneration, especially at complex tissue interfaces such as the osteochondral interface of the mandibular condyle.
Emerging modular tissue engineering approaches seek to enable the generation of large-scale tissues from the assembly or fusion of small-scale cellular constructs generated in culture. While modular tissue engineering approaches present advantages with respect to maintaining cell viability in culture prior to assembly of the building blocks, generation of modular constructs with suitable mechanical properties for load-bearing bone regeneration presents a challenge.
The growth of the field of tissue engineering over the past several decades has been remarkable. While considerable investments continue to be placed in research and development for tissue engineering technologies, translation of the technologies to the clinic to effect patient care remains the ultimate objective.
Autograft bone serves as a standard option for bone regeneration in a variety of contexts in the craniomaxillofacial complex, due in part to the osteoinductivity generally presented by the graft tissue.
