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.
