Revolutionizing Tooth Restorations: Digitized Shape Memory Matrix Band for Precision and Comfort

Posted: January 20, 2025
The article introduces a novel digitized thermo-responsive shape memory matrix band for tooth restorations, aiming to overcome the limitations of traditional matrix systems in achieving accurate proximal contours in class II restorations. The shape memory matrix band utilizes shape memory polymer (SMP) technology with reversible shapes for precise restoration. It offers customizable permanent shapes designed in software or from imaging databases, requiring only warm saline to trigger shape transformation. In vitro experiments demonstrate superior proximal profile and contact point compared to traditional metal and sectional matrices. The innovative system represents a minimally invasive and precise trend in dentistry with industrialization potential.
