The development of imaging-based bioprinting techniques for full tooth and bone regeneration in the dentoalveolar region

In dentistry, there is a wide array of patients suffering from missing or impaired tissues, including missing or lost teeth, congenital malformations, and dental trauma. Existing treatment strategies range from conservative approaches (e.g. endodontic treatment) to the use of dental implants and different types of bone grafts. Recently, there has been an increasing interest in tissue engineering strategies using 3D-printed biocompatible scaffolds, growth factors, and stem cells to mimic natural morphogenesis. However, the application of bioprinting poses several specific challenges due to the anatomical complexity and heterogeneity of dental tissues, including the root and pulp canal, periodontal ligament and alveolar bone. The current project aims to address these challenges by developing a dedicated bioprinting technique for dental applications, using an imaging-based design of the restored tissue followed by an optimized printing procedure.
