Profilometric and radiographic analyses after early implant placement in sites with ridge preservation or spontaneous healing: 3-year follow-up of an exploratory randomized controlled trial.

At 3 years, varying degrees of bone loss were observed among groups, although differences did not reach statistical significance (DBBM-C/CM, 0.02 mm; DBBM-C, −0.5 mm; SH, −0.18 mm) ( Figure 3 ).

However, a notable trend indicated substantially smaller variability of marginal bone level values in the DBBM-C/CM group compared to the other 2 groups.
