Effect of Customized and Prefabricated Healing Abutments on Peri-Implant Soft Tissue and Bone in Immediate Implant Sites: A Randomized Controlled Trial.

While the results did not reach statistical significance, they suggest a trend indicating that customized healing abutments might better preserve the papilla level, particularly in the case of the distal papilla, where tissue alterations were reduced by half in the customized group (−0.600 ± 0.750 mm and −1.232 ± 0.829 mm for the customized and prefabricated groups, respectively).
