Horizontal augmentation of the alveolar ridge – case report

Introduction: Two cases of horizontal bone augmentation of the alveolar ridge of the lower jaw after tooth loss and resulting atrophy will be presented. The goal of the procedure was to obtain an adequate width of the alveolar ridge in order to place dental implants and to gain a functional and aesthetic solution. The materials used were titanium pins, resorbable collagen membranes, xenograft, disposable bone scrapers, autogenous bone chips, membranes made of plasma enriched with growth factors, and non-resorbable polypropylene suture. Case report: In both cases, the so-called „sandwich technique” was used. After mobilizing the flap, cortical bone chips are collected with a disposable bone scraper. The preparation of the bed (decortication) is done with a round bur, the collagen membrane is fixed on one side of the alveolar ridge with titanium pins, and the space between the membrane and the alveolar ridge is filled with a mixture of autologous bone chips and xenograft. In one of the two cases presented, dentin graft was added as an additional component. After the extraction and processing of the tooth according to the given protocol, the dentin graft is obtained in the form of granules, which is mixed with the original two components. Six months later, a control CBCT (cone beam computed tomography) is performed, on which an adequate width of the alveolar ridge can be seen. The working field is reopened, all accessible pins are removed, and the dental implants are successfully placed. The obtained results are in favor of the fact that by using the mentioned technique, predictable results can be obtained during the treatment of atrophic narrow alveolar ridges.
