Popis: Background Shape and volume of the alveolar bone are determined by the shape and position of the roots. Resorption is the inevitable physiological process following tooth extraction. In the aftermath, bone volume is reduced and the morphology of the ridge has changed. To prevent resorption and maintain alveolar ridge macro and microarchitecture socket preservation technique is used. Empty alveolar is augmented with substitute material to prevent excess resorption. Aim/Hypothesis The aim of this study is to evaluate histological and histomorphometrical findings of two different xenografts after socket preservation in patients with indications for delayed implant placement. Material and Methods The study is designed as two phased controlled, randomized study. In the first phase, 40 patients that qualified for participation in the research were divided into two groups. The first group underwent tooth extractions and socket augmentation with cerabone®(Botiss Biomaterials GmbH). Sockets were covered with a resorbable collagen membrane (Jason membrane®, Botiss Biomaterials GmbH). The other group had a socket preservation technique done using BioOss® (Geistlich Biomaterials Vertriebsgesellschaft mbH) and the defects were also covered using Jason membrane®. In the second phase, after the healing period of six months and prior to implant placement, bone biopsies were harvested using trephine burrs. Samples were fixed in 4% formaldehyde, dehydrated with alcohol and put in paraffine. Staining was done using toluidine blue and analyzed under the light microscope. Results Both materials excelled in terms of clinical handling and lack of postoperative complications. So far the analysis of both materials showed incorporation of the xenograft particles into newly formed bone without inflammatory reaction. Conclusion and Clinical Implications Keeping in mind the limitations of this study as well as the preliminary nature of this presentation, it can be concluded that both materials showed excellent characteristics when used as substitutes in socket preservation technique.
