Placement of dental implants for replacing missing teeth is a well-established treatment option. There are different approaches for placement of dental implants post extraction. The approaches are immediate implant placement, delayed immediate implant placement, lateimplantation. Immediate implant placement protocol has been challenged the last decades by reducing the time between extraction of a tooth and placing and ⁄ or loading of the implant.
