*2.5. Radiological Evaluation*

According to the same study protocol as previously reported [12,46], panoramic radiographs were taken at patient's intake (T0); immediately after the MSFE procedure (T1); immediately after dental implant placement (T2); 1 year after dental implant placement (T3) and 5 years after dental implant placement (T4). On the panoramic radiographs changes in tissue height (mm) of the grafted area were measured at the implant sites on all time points. An average magnification of 1.25 was taken into account to calculate the actual tissue heights.
