Background: 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.
Methods: 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).
Result: 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).
Conclusion: 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.
