Summary

This study tested two types of temporary healing caps for dental implants: one milled from a solid block and one 3D-printed. In 22 adults, the milled caps caused less gum inflammation and bleeding over 4 weeks, likely due to their smoother surface. The findings help dentists choose the best option for early healing around implants.
