101 Immediate placement and restoration of a new tapered implant system in the aesthetic region Introduction Implant placement and restorative procedures have evolved into a procedure that can be performed immediately after tooth extraction. This approach is less time consuming than the conventional procedure and leads to increasing patient contentment (Joshi & Gupta, 2015). This is especially beneficial in an aesthetically sensitive area like the anterior maxilla. Studies have shown that this procedure has an outcome comparable to the conventional implant placement and restoration protocols (Esposito et al., 2017; Slagter et al., 2014). One of the key conditions for the success of an immediate implant placement and restoration approach is primary stability (Papaspyridakos et al., 2014). Primary stability limits micro movement and allows osteogenic cells to adhere to the implant surface, leading to osseointegration (Rodrigo et al., 2010; Smeets et al., 2016). Factors that influence primary stability are the quality and quantity of bone, surgical techniques and implant design (Rao & Gill, 2012). If osseointegration is achieved, the next challenge is to maintain stable peri-implant hard and soft tissues. This too has been a topic of research. Amongst others, to reduce peri-implant bone resorption, improvements have been made at the implant-abutment connection by platform switching and by using an internal connection type(Pozzi et al., 2014). An internal conical connection is presumed to be accompanied by less peri-implant bone loss compared to either an external connection or a straight internal connection (Koutouzis, 2019, Caricauslo et al., 2018). A new implant line has recently been presented by Straumann. The bone level implant is equipped with a deep cutting thread design and internal conical implant- abutment connection for high primary stability and minimal bone loss in fresh extraction sockets. The aim of this case series study is to describe three cases with a failing tooth in the aesthetic region (p1-p1), that were treated with this implant system following an immediate implant placement and restoration protocol. 6
