摘要

引言非龋性宫颈病变（NCCL）会损害牙齿硬组织和软组织的完整性。本病例报告介绍了一种新的跨学科技术，利用生物陶瓷基水泥（BBC）和猪胶原基质（CM）重建涉及牙釉质、牙本质和软组织的牙本质复合体。病例介绍一名38岁的健康男性因牙龈退缩27–29号牙齿和面部（F）28号深层（NCCL）涉及牙骨质-上皮连接（CEJ）缺失而被转诊至牙周病科。F#28是由英国广播公司根据制造说明修复的。27–29号软组织通过使用悬吊缝线的冠状动脉超前隧道，同时用两条CM条进行增强。在6个月的随访中，27号和29号获得了大约100%的根系覆盖率。F#28牙龈组织稳定在最大牙根覆盖率（MRC）的预期水平，距离冠状移位的CEJ顶端1mm。用树脂改性的玻璃离聚物对BBC的暴露层F#28进行贴面，以重新建立CEJ的原始位置。在为期一年的随访中，28号的根部覆盖率保持稳定，探测深度在2 mm F#27-29处保持不变。截面锥束计算机断层扫描显示，英国广播公司的修复体完好无损，适应良好。结论12个月的随访表明，BBC可能是一种可行的修复材料，同时在伴有牙龈退缩的深层NCCL中与CM进行牙龈移植。要点为什么这个案例是新信息？BBC和CM治疗宫颈深部非龋性病变的新方法。成功治疗该病例的关键是什么？BBC的位置需要平坦。用可流动复合材料固定的不可吸收悬吊缝线固定手术部位。在这种情况下，成功的主要限制是什么？成功的主要限制是血液水分控制，这可能会限制通过入口放置胶原基质条。

Vestibular tunnel approach in restoring non-carious cervical lesion gingival recessions with combination of bioceramics and collagen matrix: A case report with a 1-year follow-up

Introduction

Non-carious cervical lesions (NCCLs) can compromise the integrity to both hard and soft tissues of teeth. This case report introduces a novel interdisciplinary technique by utilizing bioceramics-based cement (BBC) and porcine collagen matrix (CM) to reconstruct the dentogingival complex where enamel, dentin, and soft tissues were involved.

Case presentation

A 38-year-old healthy male was referred to the periodontics department for gingival recessions teeth #27–29 and a deep (NCCL) on the facial (F) #28 involving the loss of the cementoenamel junction (CEJ). The F #28 was restored with BBC according to manufacturing instructions. Soft tissues of #27–29 were simultaneously augmented with two CM strips via a coronally advanced tunnel utilizing suspended sutures. At the 6-month follow-up, approximately 100% root coverages were obtained for #27 and 29. The F #28 gingival tissue stabilized at the anticipated level of maximum root coverage (MRC), 1 mm apical to the coronally displaced CEJ. The exposed layer of BBC, F #28, was veneered with resin-modified glass ionomer to re-establish the original position of the CEJ. At the one-year follow-up visit root coverage for #28 remained stable and probing depths remained unchanged at 2 mm F #27–29. A sectional cone beam computed tomography scan illustrated the BBC restoration remained intact and well adapted.

Conclusion

The 12-month follow-up illustrated that the BBC may be a viable restorable material while performing simultaneous gingival grafting with CM in deep NCCLs with gingival recessions.
