The potential benefit of socket preservation therapies was demonstrated result ing in significantly less vertical and horizontal contraction of the alveolar bone crest .
The scientific evidence does not provide clear guidelines in regards to the type of bio material , or surgical procedure , although a significant positive effect of the flapped surgery was observed .
There are no data available to draw conclusions on the consequences of such benefits on the long-term outcomes of implant therapy
OBJECTIVE This systematic review aims to evaluate the scientific evidence on the efficacy in the surgical protocol s design ed for preserving the alveolar ridge after tooth extraction and to evaluate how these techniques affect the placement of dental implants and the final implant supported restoration .
Healing of human extraction sockets filled with Bio-Oss.
The aim of this study was to investigate the healing of human extraction sockets filled with Bio-Oss particles ( Geistlich Pharma AG , Wolhusen , Switzerl and ) . In 21 subjects , providing a total of 31 healing sites , at least one tooth was scheduled for extraction and the extraction sites for implant therapy . The dimensions of the alveolar ridge at the extraction sites were considered insufficient and required augmentation concomitant with tooth extraction . There were three treatment groups . In group A , the extraction sockets were covered with a Bio-Gide membrane ( Geistlich Pharma AG ) and in group B the extraction sockets were filled with Bio-Oss . The extraction sockets in group C were left to heal spontaneously . Biopsies from the extraction sites were collected at the time of implant installation . Sample s from group A showed large amounts of lamellar bone and bone marrow and small proportions of woven bone . Sites grafted with Bio-Oss ( group B ) were comprised of connective tissue and small amounts of newly formed bone surrounding the graft particles . Only 40 % of the circumference of the Bio-Oss particles was in contact with woven bone . Sites from group C were characterized by the presence of mineralized bone and bone marrow
