Limited long-term data are available when comparing the esthetic outcomes of coronally advanced flap (CAF) with or without a connective tissue graft (CTG). The aim of this study was to compare the 4-year esthetic outcomes of CAF vs CAF + CTG for the treatment of isolated maxillary gingival recessions.
Forty-eight patients were randomly assigned for treatment either with CAF (control; N = 24) or to CAF + CTG (test group; N = 24). Patients were followed after the surgery until the final evaluation. A professional esthetic evaluation was performed using the Root coverage Esthetic Score (RES). Recession reduction, mean root coverage, and complete root coverage were also evaluated.
Forty-two patients completed the study at the 4-year recall. A significant recession reduction was evident at 4 years, without significant intergroup differences. The CAF group showed a statistically significant higher final RES compared with the CAF + CTG group (9.14 ± 1.08 vs 7.25 ± 1.29, respectively, p < 0.001). Regarding the individual components of RES, gingival margin and marginal tissue contour were significantly higher in the CAF group compared with that in the CAF + CTG group.
CAF presented with a significantly higher overall esthetic score than CAF + CTG, and in the individual RES components of marginal tissue contour and gingival margin after 4 years.
CAF without the addition of CTG provided higher esthetic outcomes for the treatment of isolated gingival recessions.
比较冠向推进瓣(CAF)联合或不联合结缔组织移植(CTG)治疗单纯上颌牙龈退缩的长期美学效果,目前仅有有限的长期数据可用。本研究旨在比较 CAF 与 CAF+CTG 治疗单纯上颌牙龈退缩的 4 年美学效果。
48 例患者随机分为 CAF(对照组;n=24)或 CAF+CTG(实验组;n=24)治疗。患者在手术后进行随访,直至最终评估。采用根覆盖美学评分(RES)进行专业美学评估。评估牙龈退缩减少、平均根覆盖和完全根覆盖情况。
42 例患者在 4 年随访时完成研究。4 年后明显的牙龈退缩减少,两组间无显著差异。CAF 组的最终 RES 明显高于 CAF+CTG 组(9.14±1.08 比 7.25±1.29,p<0.001)。在 RES 的各个组成部分中,龈缘和边缘组织轮廓在 CAF 组显著高于 CAF+CTG 组。
CAF 的整体美学评分明显高于 CAF+CTG,尤其是在 4 年后的边缘组织轮廓和龈缘 RES 各组成部分。
不联合 CTG 的 CAF 可为治疗单纯牙龈退缩提供更高的美学效果。
