Key Points

The aim is to evaluate how titanium dioxide nanotubes affect the glass transition temperature and thermal stability of denture base resin.
Incorporated titanium dioxide nanotubes into 3D printed resin at 1.0 wt%
Assessed glass transition temperature using differential scanning calorimetry (DSC)
Evaluated thermal stability through dynamic thermal analysis (DTA)
Compared results with thermomechanical analysis (TMA)
Glass transition temperature improved with 1.0 wt% titanium dioxide nanotubes
Both DSC and DTA were found to reliably assess Tg
Thermal stability showed enhancement in the resin samples

Abstract

The glass transition temperature, EM, and thermal stability of 3D printed materials improved in the 1.0 wt% group. Additionally, both DSC and DTA were found to be reliable analytic methods for Tg analysis, as they conform with the Tg results from the TMA devices.
