초록
The aim of this study is to provide an overview on the soft tissue wound healing around teeth. The classical stages of wound repair are composed of the haemostatic phase, the inflammatory phase, the proliferation phase and the remodeling phase. The oral mucosa wound heals faster and with less scar tissue formation than skin wounds and the granulation tissue originating from the periodontal ligament or connective tissue covered by keratinized epithelium has the potential to induce the keratinized tissue. The healing following non-surgical periodontal treatment is characterized by epithelial proliferation, which occurs to be completed after 7~14 days after treatment. 4 weeks after the flap surgery, the flap is re-attached to the tooth by dense connective tissue. At 5 weeks, the tissues seem to be completely regenerated. 2 weeks after free gingival graft, the epithelium had developed but no keratinization was present. A keratinized tissue was detectable at 28 days. In thicker grafts, re-vascularization appears to be more delayed, but less shrinkage was observed.
Abstract
The aim of this study is to provide an overview on the soft tissue wound healing around teeth. The classical stages of wound repair are composed of the haemostatic phase, the inflammatory phase, the proliferation phase and the remodeling phase. The oral mucosa wound heals faster and with less scar tissue formation than skin wounds and the granulation tissue originating from the periodontal ligament or connective tissue covered by keratinized epithelium has the potential to induce the keratinized tissue. The healing following non-surgical periodontal treatment is characterized by epithelial proliferation, which occurs to be completed after 7~14 days after treatment. 4 weeks after the flap surgery, the flap is re-attached to the tooth by dense connective tissue. At 5 weeks, the tissues seem to be completely regenerated. 2 weeks after free gingival graft, the epithelium had developed but no keratinization was present. A keratinized tissue was detectable at 28 days. In thicker grafts, re-vascularization appears to be more delayed, but less shrinkage was observed.
