Investigation of the esthetic appearance via PES revealed a mean point score of 10.1 (ranging from 7 to 13) from a maximum of 14. The highest values and therefore acceptance were found in the alveolar process deficiency and the soft-tissue level, which can be interpreted as a benefit of the augmentation procedure around the implant shoulder.

Peri-implant bone loss calculated using the average bone loss mesially and distally of each implant was 0.55 mm (ranging from 0 to 3 mm) without any signs of acute infection or peri-implant osteolysis. Furthermore, the radiological analysis revealed a stable bone level in all implants 3 years after loading.

Table 2 gives an overview of the results of the clinical and radiological 3-year follow-up investigation. Figure 2a–d shows clinical images of the placed implant in patient 4.
