The socket shield technique and subepithelial connective tissue graft following immediate implant placement with provisionalization had been advocated for peri-implant facial contour and gingival architecture preservation. This case report used three-dimensional volumetric analysis to longitudinally assess the peri-implant facial contour change before and after these procedures. The results demonstrated comparable and acceptable preservation of peri-implant facial contour between the two procedures after 2 years of function.
