The patient was sent back to his general dentist, who provid- ed prosthetic reconstructive treatment of tooth 47 and an individualized supportive periodontal therapy plan. The last clinical picture, taken more than 5 years after the surgery, revealed stable soft tissue contours, no signs of inflammation and physiologic probing depth. The radiograph revealed good and stable interproximal bone fill (Figures 18 and 19).

serted into the implant and tightened to 35 Ncm in order to proceed with the provisional restoration (Figure 15). Two months after the cementation of the provisional crown, a metal-ceramic crown was completed and cement- ed. After the cementation of the definitive crown, cement remnants were thoroughly removed. Gap-free seating of the definitive crown on the implant shoulder was con- firmed on the postcementation periapical radiograph (Fig- ure 16). The radiograph confirmed stable peri-implant bone levels (Figure 17).
