Çekim Soketlerinin Ogmentasyonunda Primer Kapamaya Karşı Açık Membran Tekniği

Abstract

Objectives: Funakoshi is the first one who reported 'Open Barrier Membrane' technique by using non-expanded, highdensity polytetrafluoroethylene(d-PTFE) membrane in 2005. d-PTFE membranes are impenetrable for bacteria invasion because of its surface characteristics and surgeon can leave the d-PTFE membrane intentionally exposed. The objective of this study was to investigate the clinical results of 'Open Barrier Membrane' technique in Guided Bone Regeneration (GBR) of the extraction sockets by using xenogenic bone graft and d-PTFE membranes. In this clinical study, open barrier membrane technique was compared to GBR technique. The comparison was made between the cases where the primary coverage of extraction site was obtained and the cases who completed the 6-month recovery period without exposure in terms of total bone gain. Material and Methods: Fifteen patients who were reported to have exposure in incision line during 6-month recovery period were included in open membrane group as study group (Group A). Fifteen patients who completed the 6-month recovery period without exposure were analyzed in primary coverage group as control group (Group B). The main groups were also divided into subgroups as horizontal and vertical augmentation. The amount of total bone gain was statistically compared between the groups based on the cone beam computerized tomography measurements. Results: Vertical and horizontal bone gain amounts (the main outcome variable) were statistically compared between Group A and B. There was no statistically significant difference between these groups in terms of bone gain (p=0.237 for comparison of vertical augmentation; p=0.482 for comparison of horizontal augmentation). Conclusion: Open barrier membrane technique can be considered as an alternative minimal invasive technique for both horizontal and vertical alveolar augmentation procedures.
