Effects of alveolar ridge preservation on delayed implant osseointegration.

To evaluate the effects of alveolar ridge preservation with Bio-Oss bone substitute (Geistlich Pharma) on delayed implant osseointegration. The 3rd and 4th left and right mandibular premolars were extracted from four adult healthy male and female dogs. For the experimental group, we randomly selected two extraction sockets in each dog to be filled with Bio-Oss bone substitute (Geistlich Pharma).

[Clinical retrospective study on membrane guided bone tissue regeneration technique in dental implants in the anterior maxilla].

Purpose: The purpose of this study was to investigate the effect of Bio-Gide in MGBR (membrane guided bone regeneration ) in the anterior maxilla dental implant therapy.

Methods: Fifty five cases underwent dental implant therapy in the anterior maxilla with insufficient maxillary anterior bone, including 29 patients with embedded 40 implants using MGBR and 26 patients with embedded 40 implants without using MGBR. The condition of bone around implant before implantation and before final restoration was observed and recorded.
