In Vitro Calcification of Bioprosthetic Heart Valves: Method Validation by Comparative Heart Valve Calcification Testing

Artificial Organs, EarlyView.
We have developed a unique method for pre‐clinical heart valve prostheses evaluation of calcification propensity. Results from the test can directly be translated into improvements of prostheses design, materials, and anti‐calcification treatments, and therefore have a significant impact on heart valve prostheses quality and patient care in the future.

Anatomical design and production of a novel three‐dimensional co‐culture system replicating the human flexor digitorum profundus enthesis

Journal of Anatomy, EarlyView.
Anatomical morphometrics have been used to design and manufacture models of the flexor digitorum profundus tendon to bone insertion in vitro. This innovative approach can be used to design models of other enthesis regions with anatomical and clinical applicability.

Effects of autoclave sterilization on the dimensional stability of implant surgical guides: A 3D in vitro analysis

Journal of Prosthodontics, EarlyView.
Abstract Purpose Surgical guides are medical devices used in static implant surgery to replicate the prosthetic and surgical implant position planned with computer‐assisted software before surgery. Their use reduces invasiveness and improves safety and outcomes of implant surgery, provided that their accuracy is ensured from design to manufacturing and
