摘要

目的:本研究评估改良隧道技术治疗下颌前区深度狭窄龈退缩缺损(GRDs)的3年可预测性和有效性,包括使用和不使用牙釉质基质衍生物(EMD)。方法:采用改良隧道技术联合上皮下结缔组织移植治疗31例GRDs。将该队列分为两组:一组辅助使用EMD (n=16),另一组不使用EMD (n=15)。临床结果,包括衰退深度(RD)、角化组织宽度(KTW)、平均根覆盖(MRC)和完全根覆盖(CRC),在基线以及术后6个月、1年和3年进行评估。术后2周用自我报告问卷评估患者不适。结果:3年随访,两种治疗方式临床参数差异无统计学意义,RD (EMD, -6.47±2.23 mm;非EMD, -5.10±3.23 mm), KTW (EMD, 1.03±0.96 mm);非EMD, 1.00±1.02 mm), MRC (EMD, 86.62%±21.18%;非EMD, 80.24%±38.73%)和CRC (EMD, 62.5%;non-EMD, 73.3%)。此外,两组在术后早期和主观不适(包括疼痛和肿胀)方面无显著差异。结论:在本研究的限制范围内,改良隧道技术,无论是单独使用还是与EMD联合使用,都显示出在治疗和维持深窄GRDs方面的益处。

Modified tunnel technique with and without enamel matrix derivative for deep and narrow gingival recession in the mandibular anterior region: a 3-year longitudinal and retrospective cohort population-based study.

Purpose: This study was conducted to evaluate the 3-year predictability and validity of the modified tunnel technique, both with and without the use of enamel matrix derivative (EMD), for treating deep and narrow gingival recession defects (GRDs) in the mandibular anterior region.

Methods: Overall, 31 GRDs were treated using the modified tunnel technique combined with subepithelial connective tissue graft. The cohort was divided into 2 groups: one with the adjunctive use of EMD (n=16) and the other without EMD (n=15). Clinical outcomes, including recession depth (RD), keratinized tissue width (KTW), mean root coverage (MRC), and complete root coverage (CRC), were evaluated at baseline, as well as at 6 months, 1 year, and 3 years postoperatively. Patient discomfort was assessed with a self-report questionnaire 2 weeks after surgery.

Results: At the 3-year follow-up, no statistically significant differences were observed between the 2 treatment modalities in clinical parameters, including RD (EMD, -6.47±2.23 mm; non-EMD, -5.10±3.23 mm), KTW (EMD, 1.03±0.96 mm; non-EMD, 1.00±1.02 mm), MRC (EMD, 86.62%±21.18%; non-EMD, 80.24%±38.73%), and CRC (EMD, 62.5%; non-EMD, 73.3%). Furthermore, no significant differences were found between the groups in terms of early and subjective postoperative discomfort, including pain and swelling.

Conclusions: Within the limitations of this study, the modified tunnel technique, whether used alone or in conjunction with EMD, demonstrated benefits in the treatment and maintenance of deep and narrow GRDs.
