Literature mucoderm® Komplexe, dreidimensionale Hart- und Weichgewebsrekonstruktion des Oberkiefers mit allogenen Knochenblöcken und xenogener Kollagenmatrix Ingmar Schau, Dr. Mathias Plöger. DENT IMPLANTOL 16, 2, 100-109 (2012) Für die Rekonstruktion dreidimensionaler Kieferkammdefekte vor einer Implantation bedient sich die Implantologie zumeist autogener Knochenblocktransplantate aus Beckenkamm, Symphyse oder Ramus ascendens der Mandibula. Dies bedeutet für den Patienten einen zusätzlichen OP-Situs mit zusätzlicher körperlicher Belastung und zusätzlichen Risiken. Auch für die Rekonstruktion weichgeweblicher Strukturen ist nach herkömmlichem Protokoll eine Gewebeentnahme am Körper des Patienten, zumeist aus der Gaumenregion, notwendig. Evaluation of a novel 3D collagen matrix (mucoderm®) to cover periodontal recessions Pabst A., Willershausen B., Callaway A., Ziebart T., Walter C., Kasaj A.; Universitätsmedizin Mainz; Poster NAGP 2012 Today, autologous connective tissue transplants are considered as the “gold standard“ for the treatment of periodontal recessions, although harvesting is often painful for the patient. 3D collagen matrices offer a feasible alternative for the harvesting of autologous transplants. The clinical case presented shows first clinical results with the 3D collagen matrix (mucoderm®, Botiss Dental, Berlin). In addition, the viability of gingival fibroblasts (GF) and endothelial cells (HUVEC), both playing an important role in wound healing and vascularization, was analyzed using an in vitro viability assay. The influence of mucosal tissue thickening on crestal bone stability around bone level implants. A.Puisys, T.Linkevicius, N.Maslova, E.Vindasiute, Vilnius University, Institute of Odontology Vilnius, Lithuania. Poster EAO Athens 2012 Mucosal tissue thickness has been shown as an important factor in etiology of early crestal bone loss around dental implants. Few animal studies have shown that if we have thin tissues during implant placement, crestal bone loss may occur during the formation of the biologic width. Recently, prospective controlled clinical study reported that if tissue thickness at the crest was 2 mm or less, all implants, irrespective to their position to the bone level, developed crestal bone loss within 1-year of follow-up. On the contrary, in thick tissue pattern, supracrestally placed implants had significantly less bone loss, compared to crestally positioned implants. Mucosal tissue thickness becomes very important also in short implant placement. In regions with very limited bone height, when only 6 mm or less implant could be installed, even the smallest inch of the bone support is important for the survival and stability of the implant. Sometimes limited bone height is accompanied by thin tissue biotype, thus the risk to loose crestal bone around short implants is very high. POST-EXTRACTION SOCKETS AUGMENTATION WITH ACELLULAR DERMAL MATRIX AND ALLOGENIC BONE SUBSTITUTE IN THE AESTHETIC AREA. A CASE SERIES. N. Maslova, A. Puisys, T. Linkevicius, E. Vindasiute ; Vilnius Implantology Center, Vilnius University, Institute of Odontology, Lithuania. Poster EAO Athens 2012 It is very important to keep favorable anatomical situation in the esthetic zone after tooth extraction. Many studies confirm loss of a buccal bone wall after tooth being extracted, especially in the clinical cases with thin soft tissue biotype , bone destruction due to periodontal pathology or as a result of fractured tooth root. Therefore the need of two surgical procedures occurs: implantation with bone and soft tissue augmentation and healing abutments placement after 6 months.
