Peri\u2010implant marginal bone level (MBL) was evaluated at time of loading, 3 and 12\u2009months after loading. Gingival index, plaque index, probing depth, and bleeding on probing were measured at 3, 6, and 12\u2009months after loading. Dimensional changes at implant sites were digitally evaluated using the best\u2010fit superimposition of pre\u2010and post\u2010socket preservation models. Implant aesthetic score (IAS) as well as patients' post\u2010operative quality of life were also evaluated at 12\u2009months.
