Abstract: This study introduces a Degradation-Actuated Sequential Distractor (DASD) for mandibular regeneration to reduce the high invasiveness of traditional hardware. The system combines a superelastic shape-memory Nitinol mesh with biodegradable WE43 magnesium components, converting chemical degradation into controlled, stepwise mechanical movement. To ensure biocompatibility, interfacial coatings and hydrogel buffers are integrated to suppress corrosion and […]
