THE OPEN HEALING APPROACH AND THE USE OF PLATELET-RICH GROWTH FACTORS FOR SOCKET PRESERVATION

Abstract

This clinical study evaluated the outcome of bone regeneration using an open-healing approach. We performed 80 atraumatic extraction with socket preservation in n=69 patients (0.98 sex ratio). Post extraction sockets were filled with platelet-rich autologous plasma factors Endoret® (PRGF®) clots covered with fibrin membrane and were left exposed during healing. The bone volume was measured and the need for an additional augmentation in the implant stage was assessed using CBCT scans at t=8 weeks. This analysis showed that open healing technique using PRGF allowed uneventful healing and sufficient bone formation. Thereby, soft-tissue problems associated with extensive flap mobilization and tension may be avoided. We concluded that the use of PRGF in socket preservation with the open healing approach can be favorable from both clinical and radiological points of view. Furthermore, there was almost no need for additional augmentation in the implant stage and the number of complications was limited.
