Randomized trial evaluates bone regeneration scaffolds in human dental pulp stem cells, suggesting potential for improved osteogenic responses.

The aim was to evaluate the physicochemical and biological properties of HAp/PLGA/CS scaffolds for bone regeneration.
Developed HAp/PLGA/CS scaffolds using freeze-drying and 3D printing techniques.
Characterized morphology, porosity, and mechanical properties of the scaffolds.
Conducted finite element analysis to assess scaffold behavior under simulated dental implant loading conditions.
3D-printed scaffolds had 85% cell viability, significantly higher than 50% in freeze-dried scaffolds.
70% infill scaffolds displayed enhanced expression of osteogenic markers RUNX2 and OSX.
Finite element analysis indicated the need for mechanical optimization to improve load transfer.

Pérez-Bohorquez et al. (2026) studied this question.
