40 consecutive adult patients, requiring the insertion of dental implants in the aesthetic area (from second premolar to second premolar) will be enrolled in the study. At the time of surgery, a full thickness flap will be elevated, the implant bed will be prepared according to the manufacturer's instruction and the implants will be then seated into the bone. T0 corresponds to the time of implant insertion, T1 to the time of healing abutment's connection (T0=T1 for single stage implants), and T2 corresponds to 1-year follow-up from healing abutment's connection. Cone Beam Computed Tomography (CBCT) scans will be taken immediately after abutment connection (T1) and 1-year after (T2). The midsagittal cut of each implant will be identified, and measurements will be made at predetermined levels. Horizontal facial bone thickness (HFBT) and Vertical facial bone level (VFBL) will be measured. HFBT will be measured at 0, 3, 6 and 9 mm apical to the implant platform. VFBL wil be the perpendicular distance from the implant platform to the most coronal point of the facial bone. Changes between T1 and T2 will be calculated.
