Lops D, et al. – The present study sought to compare the interproximal papilla stability of restorations supported by computer–aided design/computer–assisted manufacture (CAD/CAM) abutments to those supported by prefabricated stock abutments in anterior areas over a 2–year follow–up. The results of this study revealed that the use of titanium and zirconia CAD/CAM abutments was associated with better interproximal papillae stability.
