Abstract

Objective: The objective of this randomized clinical trial (RCT) was to analyze the clinical outcomes of labial gingival tissue augmentation throughout stage II implant surgery in subjects with thin gingival phenotype (GP) using the free sub-epithelial connective tissue graft (FSCTG) versus Omega roll envelop flap technique (OREF).

Subjects and Methods: Sixteen patients with thin GP (˂ 1.5 mm) got 20 implants in this 6—month follow up RCT and split into two groups. 1) Group I: 8 patients got 10 implants in stage I surgery and got OREF for labial soft tissue augmentation in stage II surgery. 2) Group II: 8 patients got 10 implants in stage I surgery and FSCTG in stage II surgery. The clinical parameters of gingival thickness (GT), width of keratinized mucosa (KM), visual analog scale (VAS), and pink esthetic score (PES) were estimated at baseline, 1, 3 and 6 months follow-up intervals. Comparing GT, KM among groups and observation times was made suing repeated measures ANOVA succeeded by Bonferroni test for multiple comparisons. For all tests, P ≤0.05 was set as significant.

Results: Both groups' averages of GT and KM increased statistically significantly. Yet, over the course of the study's follow-up intervals, there was no significant difference in the means of GT among the two groups. The mean values of the PES increased significantly within both groups. Means of VAS of Group II were statistically substantially more than those of Group I at the one- and three-month follow-up intervals.

Conclusions: OREF procedure is useful in enhancing the dimensions of thin facial gingival tissue surrounding the dental implants. When compared to SCTG as a phenotype-modifying therapy surrounding dental implants, the OREF technique may be considered a novel and appropriate treatment option due to its convenience, good patient acceptance, and less postoperative discomfort. The choice between these two approaches may depend on the particular clinical situation, the preferences of the patient, and the intended results of the augmentation.
