Use of guided tissue regeneration to treat a mucogingival defect associated with interdental bone loss: a case report
The purpose of this paper is to present a case report on the successful use of guided tissue regeneration and placement of demineralized freeze-dried bone allograft as a space maintainer to manage a mucogingival defect associated with interdental bone loss. The patient presented with a mucogingival defect on the mandibular left center incisor that consisted of 2 mm of facial gingival recession, a 5 mm probing depth on the facial aspect, and 6 mm probing depths on both the mesial and distal aspects. A regenerative procedure consisted of citric acid demineralization and placement of demineralized freeze-dried bone allograft and Gore-Tex membrane. In eight monthsı postsurgery, a gain of 4.5 mm of clinical attachment (64%) and 86% of root coverage was documented. The result surpassed expected outcomes of alternative treatment modalities.
