Background: The aim of this study to investigate three-dimensional quantitative analysis buccal augmented tissue alterations after modified coronally advanced tunnel (MCAT) technique combined with subepithelial connective tissue graft (SCTG) within 1-year based on intraoral scanning.
Methods: 25 Cairo class I gingival recession defects were treated by MCAT technique with SCTG. Two examiners performed digital three-dimensional measurements, including the preoperative gingival recession height (GH), width (GW) and root exposed area (REA), postoperative gingival height gain (HG), area gain (AG), volume gain (VG) and mean thickness gain (MTG) of region of interest (ROI). Then, dynamic alterations of ROI and buccal tissue at 2 weeks, 6 weeks, 3 months and 1-year post-op were analysis.
Results: Intra-class correlation coefficients (ICC) showed almost perfect inter-examiner reliability for digital measurement (ICC > 0.89). Postoperative HG, AG, VG and MTG were encountered distinct at 2 weeks post-op, then gradually decreased. At 1-year, AG, VG and MTG were 7.614 ± 2.511mm2, 7.690 ± 4.335mm3 and 0.965±0.372mm, respectively. Significant decreases were recorded between 6 weeks and 1-year in terms of HG, AG and VG. The MTG was sustained after 6 weeks with an increase of nearly 1mm at 1-year.
Conclusions: Digital measurement by intraoral scanning offered an advantage of clinically feasible, non-invasive and reliable evaluation method for achieving volumetric outcomes after periodontal plastic surgery. Augmented tissue acquired by MCAT with SCTG tends to be stable after 3 months post-op.
Trial registration：This study was retrospectively registered in Chinese Clinical Trial Registry: ChiCTR1900026768. Date of registration: 21/10/2019.
