109 Immediate placement and restoration of a new tapered implant system in the aesthetic region 90.0. This is in line with other studies on immediate placement and provisionalisation protocols, where PES scores of 7.5±1.6 (Meijer et al., 2019) and 6.8±1.5 (Zuiderveld et al., 2018) were published on immediate implant placement protocols. All patients reached the threshold of clinical acceptability (score ≥6) (Belser et al., 2009). One patient was pregnant at the final follow-up and showed signs of inflammation around the implant and other natural teeth. There is a connection between increased plasma levels during pregnancy and gum disease (Chapple et al., 2018). Because the same inflammatory signs were present at the neighbouring teeth, it can be assumed that the marginal peri-implant soft tissues are affected due to the pregnancy hormones. The initial results of this implant are favourable. However, this is a report of three patients followed for a short period of time. Studies with larger population and a longer follow-up are needed to view the stability of the facial hard and soft tissues in the long-term, as various studies have shown that hard and soft tissue alterations can be observed after many years in function (Kan et al., 2011; Cosyn et al., 2018; Raes et al., 2018). Conclusion Within the limitations of this study, it can be concluded that immediate implant placement and provisionalisation using this implant has the potential to result in favourable clinical, radiographic, aesthetic and patient satisfaction outcomes. 6
