Abstract: Regenerative surgery is an effective treatment of intraosseous defects, however, subject with thin gingival tissue phenotype and bone dehiscence defect tends to have more post-surgery gingival recession. The gingival recession is considered as soft tissue loss, which may affect the result of periodontal regeneration. Therefore, this case series aimed to describe a periodontal regenerative surgery combined with subepithelial connective tissue graft (SCTG) in intraosseous defects associated with buccal gingival recession would make periodontal regeneration more predictable. Materials and Methods: The case series describes a surgical approach to improve regenerative parameters in deep intraosseous defects associated with buccal gingival recession. Teeth with buccal bone dehiscence or furcation involvement were included. The surgical technique consisted of an SCTG placed on the buccal dehiscence defect or furcation area to thicken the soft tissue wall, then treated with enamel matrix derivative and biomaterials as regenerative scaffolds inside the intraosseous component of the defect. Results: In all cases, there were buccal gingival margin thickness increased, significant clinical attachment level gain, bone level gain, reduced probing pocket depth, and partial root coverage at least one year after the surgery. The radiographs demonstrated increased bone density of the deep intraosseous defects associated with buccal gingival recession in both single root and furcation-involved teeth. Conclusion: The combination of regenerative treatment and SCTG in intraosseous defects associated with buccal gingival recession in a single root or furcation-involved molar supports the stability of the gingival profile and improves root coverage outcome as well as periodontal regeneration. |
