Abstract

Purpose: To evaluate the clinical efficacy of the coronally advanced lingual flap (CALF) technique in terms of the extent of lingual and buccal flap advancement, the maintenance of primary wound closure, and safety in comparison to buccal flap advancement alone during horizontal ridge augmentation in the posterior mandible.

Materials and methods: A total of 14 patients were randomly allocated to two different groups: buccal flap advancement without the CALF technique (control), referred to as the NO-CALF group, and buccal flap advancement with the CALF technique (test), referred to as the CALF group. Wound healing was monitored weekly for the first 4 weeks, then at 2, 4, 6, and 9 months postoperatively for any soft tissue dehiscence (titanium mesh [TM] exposure) along the incision line. The extent of lingual and buccal flap advancement was measured, and any intraoperative and postoperative CALF-related complications were reported.

Results: The difference between groups was statistically significant (P < .0001) in terms of (1) TM exposure: 83.3% of cases in the NO-CALF group showed early Class П exposures, whereas the CALF group showed no exposure; (2) mean lingual flap advancement: 3.9 ± 1.1 mm and 14.4 ± 3.8 mm for the NO-CALF and CALF groups, respectively; and (3) mean buccal flap advancement: 15.8 ± 2.1 mm and 10.5 ± 1.4 mm for the NO-CALF and CALF groups, respectively. There were no reported complications related to the CALF technique.

Conclusion: Tension-free primary wound closure was facilitated and maintained during the healing period by applying the CALF technique, which is a reliable technique to safely advance the lingual flap coronally.

钛网引导下骨再生后应用冠状先进舌瓣维持原发性伤口闭合的临床评价:一项随机对照试验。
目的:在下颌后嵴水平隆凸过程中,与单独推进颊侧皮瓣相比,评估冠状动脉推进舌侧皮瓣(CALF)技术在舌侧和颊侧皮瓣推进程度、原发伤口闭合的维持和安全性方面的临床疗效。材料和方法:共有14名患者被随机分配到两个不同的组:不使用CALF技术的颊瓣推进(对照组),称为NO-CALF组,以及使用CALF方法的颊瓣前进(测试组),也称为CALF组。在前4周每周监测伤口愈合情况,然后在术后2、4、6和9个月监测切口沿线的任何软组织开裂(钛网[TM]暴露)。测量舌颊皮瓣推进的程度,并报告任何术中和术后CALF相关并发症。结果:就(1)TM暴露而言,两组之间的差异具有统计学意义(P<.0001):NO-CALF组83.3%的病例显示早期П类暴露,而CALF组没有显示暴露;(2) 平均舌侧皮瓣前移:NO-CALF组和CALF组分别为3.9±1.1 mm和14.4±3.8 mm;(3)平均颊瓣前移:NO-CALF组和CALF组分别为15.8±2.1 mm和10.5±1.4 mm。没有报告与CALF技术相关的并发症。结论:应用CALF技术可促进和维持无张力的原发性伤口闭合,这是一种安全推进舌侧皮瓣冠状动脉的可靠技术。

期刊介绍: The International Journal of Periodontics & Restorative Dentistry will publish manuscripts concerned with all aspects of clinical periodontology, restorative dentistry, and implantology. This includes pertinent research as well as clinical methodology (their interdependence and relationship should be addressed where applicable); proceedings of relevant symposia or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published or submitted for publication elsewhere.
