Root coverage using subepithelial connective tissue graft / 대한치주과학회지

PURPOSE: One of the main objectives of periodontal reconstructive surgery is the coverage of exposed roots that occur due to gingival recession. and Aestheic concerns are usually the reason to perform root coverage procedure. This case report was performed to evaluate the effect of root coverage using subepithelial connective tissue graft(SCTG) on Miller's Class I marginal tissue recession. MATERIALS AND METHODS: One patient, with two Miller's class I marginal tissue recession on both maxiallay canines, was treated with root coverage using SCTG (modified Nelson's technique). At baseline, the following measurements were recorded: 1) recession depth; 2) width of keratinized giniga. At 9, 10 months post-surgery, all clinical measurements were repeated. RESULT: 1) The mean root coverage from baseline to 9, 10 months post-surgery was 92.3%. 2) The mean recession depth decreased from 6.5 mm to 0.5 mm. 3) The mean width of keratinized gingiva increased from 1.25 mm to 3.5 mm. CONCLUSION: Within the above results, root coverage using SCTG is an effective procedure to cover Miller's class I marginal tissue recession defect. Also, patient with aesthetic concern could be satisfied with this result.

The evaluation of clinical outcomes on various procedures using subepithelial connective tissue graft for coverage of gingival recession / 대한치주과학회지

PURPOSE: The subepithelial connective tissue graft(SCTG) has been proven to be a highly predictable treatment modality for coverage of gingival recession. This case report was performed to evaluate the effect of various root coverage procedures using SCTG on gingival recession. MATERIALS AND METHODS: Three patients presents with Miller's class I recession defect on the maxillary canine. Each other SCTG(coronally advanced flap, Bruno's Tech., envelope Tech.) were performed for root coverage. Clinical parameters assessed included recession depth, recession width, and keratinized gingival width. Measurements were taken at baseline and 2 months and follow up end. RESULTS: The average of root coverage was 4 mm(100% of the pre-operative recession depth) at the 2, 5 months examination. The average increase of keratinized tissue between the baseline and the 2 months amounted to 3.2mm. CONCLUSION: Within the above results, various root coverage using SCTG is an effective procedure to Miller's class I recession defect and patient could be satisfied aesthetic requirement.
