Fig. 3

Representative microscopic images (upper row, ×200, and lower row, ×2000) of fractured 3D-printed bar-shaped denture base specimens subjected to different post-polymerization time (PPT) protocols: 5-min, 10-min, 20-min, and 30-min. Control: 3D-printed denture base resin discs without microcapsules; Capsule: 3D-printed denture base resin discs with 5 wt% phytoncide-filled microcapsules. a Brittle fracture with smooth surface and chevron marks; b–e intermediate (ductile) fracture with rough surface and jagged areas. Note the microcapsules are evenly distributed over the fractured surfaces
