1. Introduction Over the last two decades, oral implantology has progressed, resulting in a simplification of the surgical procedure and a reduction in the treatment period. Comparable results have been achieved in the switch from two-stage surgery to one-stage [1,2,3,4]; moderately rough and bioactive implant surfaces [5] have facilitated early- [6,7,8] and immediate loading [9]. Immediate implant placement became possible in properly selected patients [10].
