Disorders affecting the temporomandibular joint (TMJ) significantly impact patients’ quality of life by impeding basic activities such as speaking and eating [1]. The field of complex tissue regeneration aims to engineer scaffolds that can replace the osteochondral interface of the TMJ, combining different biomaterials, biofabrication techniques, and cells [2]. In this Master’s thesis, we propose the design of a multimaterial scaffold for the replacement of the TMJ in a single construct. The goal is to combine melt electro-writing, an emerging technique that relies on voltage-stabilized jets to produce microscale polymer fibers with excellent mechanical stability [3], with a bioactive protein-based hydrogel. The project is a collaboration with the MERLN Institute for Technology and Regenerative Medicine at Maastricht University, NL, where all experimental work is being conducted.
