Soft tissue deficiency around dental implants can negatively impact outcomes in terms of esthetics and long-term stability. While autogenous connective tissue grafting is still considered the gold standard treatment, alternative approaches are being proposed primarily to enhance patient comfort and avoid invasive procedures such as two-sites surgeries using xenogeneic collagen matrices. Despite the advantages, the quality of the regenerated tissues remains unpredictable and, in many cases, questionable, highlighting the need for alternative and innovative approaches. After introducing in a previous technical note, the "HAT-TRICK" technique, to address these challenges in pontic sites, the present study highlights the "HAT-TRICK" technique for thickening the keratinized gingiva in both immediate and delayed implant placement sites within the esthetic zone. The "HAT-TRICK" technique is demonstrated through two clinical cases, accompanied by a digital comparison conducted at baseline and after one year of follow-up in order to assess and quantify the augmented areas.
牙种植体周围的软组织缺损会对美学效果和长期稳定性产生负面影响。虽然自体结缔组织移植仍被视为金标准治疗方法，但人们主要为提高患者舒适度并避免诸如使用异种胶原基质的双位点手术等侵入性操作而提出了替代方法。尽管有这些优点，但再生组织的质量仍然不可预测，而且在许多情况下存在问题，这凸显了对替代和创新方法的需求。在之前的一篇技术说明中介绍了“帽子戏法”技术以应对桥体部位的这些挑战之后，本研究重点介绍了用于增厚美学区即刻和延期种植部位角化龈的“帽子戏法”技术。通过两个临床病例展示了“帽子戏法”技术，并在基线和随访一年后进行了数字对比，以评估和量化增大的区域。
