Soft tissue management for immediate implant placement in the esthetic zone is crucial for successful treatment outcomes. Several surgical and restorative techniques have been proposed to treat unesthetic implant soft tissue defects or dehiscence. However, there is a scarcity of clinical evidence on addressing complications associated with through-and-through soft tissue defect (TTSD). In this case, a 61-year-old female patient, who underwent immediate implant placement at the right central incisor 3 months prior, presented with chronic peri-implant mucosal infection and soft tissue recession of TTSD in 2015. The palatal pedicle connective tissue flap (PPCTF) was utilized to provide horizontal and vertical soft tissue augmentation and to cover the defect in combination with the labial contour collapse. At the 8-year follow-up, favorable white and pink esthetic outcomes were observed, and the pink esthetic score (PES) for soft tissue around the implant achieved 9 points, indicating satisfactory esthetic and functional results. The findings from this case study suggest that soft tissue augmentation techniques, such as PPCTF grafts, can provide a reliable and innovative method for both soft tissue augmentation and reconstruction of TTSD, resulting in long-lasting functional and esthetic outcomes and stable ideal PES scores.
在美学区域即刻种植时的软组织管理对于获得成功的治疗效果至关重要。已经提出了几种外科和修复技术来治疗不美观的种植体软组织缺损或裂开。然而，关于处理与贯通性软组织缺损（TTSD）相关并发症的临床证据却很匮乏。在此病例中，一名61岁女性患者于2015年就诊，该患者3个月前在右上中切牙处进行了即刻种植，现出现慢性种植体周围黏膜感染和TTSD的软组织退缩。采用腭蒂结缔组织瓣（PPCTF）来提供水平和垂直方向的软组织增量，并结合唇侧轮廓塌陷来覆盖缺损。在8年的随访中，观察到了良好的白色和粉色美学效果，种植体周围软组织的粉色美学评分（PES）达到了9分，表明美学和功能结果令人满意。该病例研究的结果表明，诸如PPCTF移植等软组织增量技术可为TTSD的软组织增量和重建提供一种可靠且创新的方法，从而产生持久的功能和美学效果以及稳定理想的PES评分。
