摘要: In an experimental study using the Gottingen minipig, Gore-Tex, Gore Resolut, and Vicryl barrier membranes were tested for their efficacy in guided bone regeneration. The results compared to those of autologous periosteum. strongest reossification was seen defects covered with Gore-Tex; however, time-dependent disintegration phenomena, which had already been observed preliminary examinations, clearly established. After investigations cell cultures human macrophages added, latter findings can be interpreted as result a physicochemical process, since direct attack by not vitro. Of used, absorbable ones tended collapse, depending on size defect that they did enhance much permanent membranes. periosteum-covered showed satisfactory degree regeneration, no differences between freely transplanted pedunculate
