This study presents a novel Low Invasiveness Design (LID) flap for Immediate Implant Placement (IIP) and evaluates its clinical and esthetic outcomes in a 20-patient retrospective case series. The LID flap is based on recent insights into papilla vascularization and aims to balance the benefits of flapless and conventional flap techniques.
Twenty patients requiring IIP in the anterior maxilla were treated with the LID flap. The study included non-smoking, systemically healthy individuals. Esthetic outcomes and patient satisfaction were assessed one year after final prosthetic rehabilitation respectively using the Pink Esthetic Score (PES) and the Visual Analogue Scale (VAS).
No implant failures or major complications were reported. A minor case of flap distress (5%) was observed and healed spontaneously without intervention. The mean PES was 12.35 ± 0.99, indicating satisfactory esthetic outcomes, while the mean VAS score was 9.15 ± 0.75. The flap design successfully preserved papilla height and granted soft tissue stability.
The LID flap presents a promising approach for IIP, preserving soft tissue esthetics while ensuring surgical precision. The preliminary results suggest that this technique may provide an alternative to traditional flap designs.
The LID flap may serve as an alternative to traditional incision designs in IIP procedures.
本研究提出一种用于即刻种植的新型低侵袭性设计（LID）瓣，并在一项纳入20例患者的回顾性病例系列中评估其临床和美学效果。LID瓣基于对乳头血管化的最新认识，旨在平衡无瓣和传统瓣技术的优点。
20例上颌前部需要即刻种植的患者接受了LID瓣治疗。该研究纳入了不吸烟、全身健康的个体。在最终修复完成一年后，分别使用粉色美学评分（PES）和视觉模拟量表（VAS）评估美学效果和患者满意度。
未报告种植体失败或重大并发症。观察到1例轻微的瓣区不适（5%），未经干预自行愈合。平均PES为12.35±0.99，表明美学效果满意，而平均VAS评分为9.15±0.75。瓣设计成功保留了乳头高度并确保了软组织稳定性。
LID瓣为即刻种植提供了一种有前景的方法，在确保手术精确性的同时保留了软组织美学效果。初步结果表明，该技术可能为传统瓣设计提供一种替代方案。
LID瓣可作为即刻种植手术中传统切口设计的替代方案。
