Overview
The Kasper Laboratory applies fundamentals of engineering, materials science, and the biosciences toward the development and evaluation of biomaterial-based technologies to meet clinical needs, with a particular focus on tissue regeneration, cell encapsulation, and the controlled delivery of therapeutics. Each project in the Kasper Laboratory builds upon the foundational concept that tunable material or environmental parameters can be harnessed to direct cellular and tissue interactions, control the delivery of therapeutics, and positively influence clinical outcomes. Examples of research directions in the laboratory include:
DENTAL AND CRANIOFACIAL APPLICATIONS OF 3D PRINTING
Advances in medical imaging and computer-aided manufacturing platforms, such as 3D printing, enable exciting new frontiers in the application of biomaterials for patient care. The Kasper Laboratory leverages these technologies in the development of biomaterial-based approaches to meet clinical needs, with a particular focus on moving and building craniofacial tissue for improved function and esthetics. His laboratory explores emerging applications of 3D printing in dentistry and craniofacial reconstruction, including 3D-printed surgical guides to facilitate dental implant placement and 3D-printed anatomical models for treatment planning. Recent publications from his laboratory report the effects of tunable aspects of the 3D printing process on the potential clinical utility of 3D-printed models and devices for a variety of applications to inform evidence-based implementation of 3D-printing technology in patient care. In parallel with these efforts, Dr. Kasper’s laboratory investigates innovative applications of 3D printing technologies for the production of patient-matched appliances to direct desired movement of craniofacial tissues. Examples include clear orthodontic aligners and esthetic orthodontic brackets to enable orthodontic tooth movement and 3D-printed nasoalveolar molding appliances to facilitate surgical correction of cleft lip and palate. In collaboration with Dr. Simon Young (Assistant Professor, Department of Oral and Maxillofacial Surgery), Dr. Kasper investigates pre-clinical application of 3D-printed scaffolds to support craniofacial bone regeneration in clinically relevant models, which present potential to impact repair of craniofacial defects arising from birth defects, cancer, and trauma.
BIOACTIVE CONSTRUCTS FOR TISSUE ENGINEERING
Tremendous effort has been invested in the development of biomaterials capable of actively promoting tissue regeneration, especially in defects affecting musculoskeletal tissues such as bone and cartilage. Although synthetic materials provide an excellent and versatile platform for the fabrication of scaffolds to support tissue regeneration, the materials themselves generally lack the biological activity required to promote tissue repair. In order to impart biological activity to synthetic scaffolds, while retaining the versatility of the materials, the Kasper Laboratory leverages the culture of cell populations under engineered conditions on three-dimensional scaffolds to direct the differentiation and phenotypic expression of the cells and to introduce biologically active extracellular matrix components into the constructs for tissue engineering applications.
