Although alveolar ridge preservation (ARP) has the advantage of reducing alveolar bone resorption after tooth extraction, weak primary stability occurs during implant placement. Immediate implant placement with open healing ARP (iARP) has been implemented to achieve primary stability and to take advantage of both immediate implantation and ARP. Herein, we describe three cases of iARP using deproteinized bovine bone mineral (DBBM) and native bilayer collagen membrane (NBCM) without primary closure. In all cases, delayed healing of the soft tissue was observed, but the implant and bone conditions were maintained without any complications for more than 19 months. Within the limitations of this report, iARP is considered a procedure that can overcome the disadvantages of immediate implant placement and ARP and take advantage.
