Space provision is one of the main problems in non-space making defects, considering the softness of resorbable membranes. In this study, we tested the possibility to create and maintain a secluded space using a slow, long-lasting resorbable suture so that a resorbable dome device could support the barrier and immediately become a space-making device. Ten purely mucogingival recessions in ten patients were treated. At 12 months, the results were evaluated. In five subjects the gingival margin was within 1 mm of the cementoenamel junction, in four patients it was within 2 mm, and in one case a residual gingival recession was present (where the membrane became exposed). The mean root coverage obtained was 70.4%, while the mean gain of clinical attachment was 3.3 mm.
