摘要

技术报告描述了一种新的治疗方案,从术前评估、皮瓣准备和嫁接材料的联合使用,来治疗具有解剖学复杂性的多重衰退。术前采用临床检查和锥束计算机断层扫描进行综合评估。手术入路时,采用双椎板隧道技术(cTUN)。首先,在最严重的牙位进行隧道冠状推进皮瓣(tCAF),并采用改良隧道技术与改良隧道及前庭切口骨膜下隧道通道(mVISTA)相结合,从两个方向绕过解剖障碍。最后,在冠状面缝合脱上皮游离牙龈移植物(DCTG),覆盖牙龈退行,在根尖部分厚度皮瓣放置体积稳定的胶原基质(VSCM),填充牙龈凹陷。在确定高复杂性和解剖困难的情况下,ctn技术结合tCAF和mVISTA入路,在皮瓣制备过程中有效地保持了皮瓣的完整性,根覆盖的临床效果良好,根据所报道的病例随访6个月软组织的稳定性。

A Combined Bilaminar Tunnel Technique Using a Volume-Stable Collagen Matrix for Root Coverage in Anatomically Complex Sites: Technique Description and Report of Two Cases.

The technical report described a novel treatment protocol for multiple recessions with anatomy- driven complexity from pre-operative evaluation, flap preparation, and the combination use of grafting materials. Clinical examination and cone-beam computed tomography were used to perform the comprehensive assessment before surgery. During surgical approach, sequentially combined bilaminar tunnel technique(cTUN) was performed. Firstly, tunneled coronally advanced flap (tCAF) was made at the most severe tooth sites, and the combination of modified tunnel technique with modified tunnel and vestibular incision subperiosteal tunnel access (mVISTA) was used to bypass the anatomic obstacles from two directions. Lastly, the de-epithelialized free gingival graft (DCTG) was sutured at coronal part for gingival recession coverage, and the volume-stable collagen matrix (VSCM) was placed at apical partially thickness flap to fill the concavities. When high complexity with anatomic difficulties was determined, the cTUN technique, combined tCAF and mVISTA approaches, effectively led to the preservation of flap integrity during flap preparation, favorable clinical outcomes of root coverage, and the stability of soft tissue at 6-month follow-up based on the reported cases.
