Abstract

The integrity of periodontal soft tissues during healing plays a critical role in the success of surgical periodontal regenerative therapy. Wound dehiscence can lead to compromised regenerative outcomes and gingival recession. This manuscript introduces the use of the partial-full-thickness (PFT) tunnel for periodontal regeneration of multiple adjacent infrabony defects. The PFT tunnel technique maintains intact interdental papillae, enables access to defects, and facilitates coronal advancement of the soft tissue. When combined with palatal vertical incision this approach also enables treatment of bony defects that extend toward the palatal aspect. Placement of biomaterials in osseous defects displaces the overlying soft tissue coronally, thereby creating and maintaining space for clot stabilization and tissue regeneration. It also leads to significant enhancement in interproximal clinical attachment levels, probing depth reduction, and root coverage. Preliminary clinical outcomes indicate that this technique could be an alternative option for treating multiple infrabony defects.

局部-全层隧道技术治疗牙周再生:技术描述及2例报告。
牙周软组织的完整性对牙周外科再生治疗的成功起着至关重要的作用。伤口开裂可导致受损的再生结果和牙龈衰退。本文介绍了局部全层(PFT)隧道在牙周修复邻近多处下颌骨缺损中的应用。PFT隧道技术可以保持完整的牙间乳头,使修复缺损成为可能,并促进冠状面软组织的推进。当与腭垂直切口相结合时,这种入路也可以治疗向腭侧延伸的骨缺损。在骨缺损中放置生物材料可在冠状面置换覆盖的软组织,从而为凝块稳定和组织再生创造和维持空间。它还导致近端间临床附着水平的显著增强,探测深度减少和根覆盖。初步的临床结果表明,该技术可能是治疗多发性骨下缺损的另一种选择。
