BACKGROUND/AIM: To report cases in which we achieved sufficient width of the keratinized gingiva using a coronally advanced flap in combination with a subepithelial connective tissue graft (SCTG) obtained by the 'CO laser de-epithelization technique' (CODE).
Eleven patients with 21 Miller Class I, II, and III gingival recessions had surgery. To prepare SCTG, free gingival grafts were harvested and de-epithelialized extra-orally. De-epithelialization was conducted by irradiation of CO laser. Postoperative examinations were performed at 12 months.
At 12 months, statistically highly significant root coverage was achieved in all recessions. Complete root coverage was obtained in 7 of the 21 recessions. The treatment yielded mean root coverage of 41.0%, and was associated with a mean gain of keratinized gingiva of 2.9±0.3 mm.
The use of CODE allows harvesting grafts of excellent quality and quantity and increases the keratinization of the overlying mucosal epithelium.
背景/目的：报告我们使用冠向推进瓣联合应用通过“CO 激光去上皮化技术”（CODE）获得的黏膜下结缔组织移植（SCTG），从而实现足够角化龈宽度的病例。
11 名患者的 21 个 Miller 分类 I、II 和 III 牙龈退缩接受了手术。为了制备 SCTG，从口腔外切取游离牙龈并进行去上皮化。通过 CO 激光照射进行去上皮化。术后 12 个月进行检查。
在 12 个月时，所有的牙周袋均获得了统计学上显著的根面覆盖。21 个牙周袋中有 7 个完全覆盖了根面。该治疗方法的平均根面覆盖率为 41.0%，并伴有平均 2.9±0.3mm 的角化龈增加。
使用 CODE 可以获得质量和数量优良的移植物，并增加覆盖黏膜上皮的角化。
