A minimally invasive aesthetic suturing technique was employed in aesthetic crown lengthening surgery (ACLS). The objective of this report was to evaluate the clinical and patient- reported outcomes of this technique for ACLS. Fifteen patients who underwent ACLS were treated utilizing the described suturing technique. Clinical parameters, including plaque index (PI), gingival index (GI), bleeding index (BI), papilla index score (PIS), early wound healing index (EHI), visual analogue scale (VAS), pink esthetic score and white esthetic score (PES/WES), were recorded at baseline, immediately post-surgery and during follow-up visits spanning 5 days to 24 months. The two-sample t-test was performed to evaluate statistical significance (α = 0.05). 100% of the patients reported a high level of satisfaction, with a stable high postoperative VAS scores. From baseline to 5-day postoperation, there was no statistically significant increase in PI, although there was a slight deterioration observed in GI (0.13Å}0.23, P<0.05) and BI (0.49Å}0.55, P< 0.05). Early wound healing (EHI 1) was achieved by all patients at 5 days post-surgery. Additionally, 3 patients exhibited changes in PIS within the initial 3 months following surgery, after which, all patients attained an optimal degree of papilla filling (degree III). The application of the minimally invasive aesthetic suturing technique in ACLS demonstrates favorable outcomes in terms of patient satisfaction and long-term stability. However, the assertion of its superiority over conventional suturing methods for ACLS necessitates substantiation through rigorous investigation via well-designed randomized controlled clinical trials.
