The document describes a case report of placing a 3.4mm implant in the upper jaw without sutures using Flex Barrier, a crosslinked hyaluronic acid membrane. Flex Barrier stabilized the soft tissue around the gingival former immediately, preventing the need for sutures. The case report shows that Flex Barrier allows for fast wound closure and good handling during application and injection into soft tissue. It also results in voluminous soft tissue and naturally looking papillae without additional surgery.
