The biocompatibility of cyanoacrylate tissue adhesive in conjunction with a collagen membrane for providing soft and hard tissue regeneration in extraction socket preservation procedures

This clinical investigation was performed to determine the efficacy of cyanoacrylate tissue adhesive to enhance soft and hard tissue healing of extraction wounds requiring a regenerative effort. Fourteen patients requiring a total of 25 tooth extractions were selected. Twenty sockets were treated with cyanoacrylate tissue adhesive over an exposed collagen barrier membrane without altering the mucogingival junction, while five extraction sockets were allowed to heal by the secondary healing intention as well but without tissue adhesive application. The results were evaluated with emphasis on soft tissue color and form as well as bone surface morphology. All sites received dental implants. There was a clear advantage to using cyanoacrylate tissue adhesive as a protective mechanism over an exposed collagen barrier membrane.
