Abstract

Objective. The purpose of this clinical research was to evaluate the result of microinvasive surgical technology: vestibular incision subperiosteal tunnel access (VISTA) and subepithelial connective tissue graft (SCTG) in multiple gingival recession. Methods. A total of 20 patients with 25 Miller I and 30 Miller III gingival recession teeth were treated with VISTA+SCTG. The data at baseline and 12 months were assessed: probing depth (PD), clinical attachment loss (CAL), gingival recession depth (RD), gingival recession width (RW), width of keratinized tissue (WKT), and gingival biotype (GB), and percentage of root coverage (RC) and complete root coverage (CRC) were calculated. Results. The average root coverage was 1.52 ± 0.70 mm in Miller I and 0.82 ± 0.79 mm in Miller III. The mean root coverage rate was 99.00 % ± 5.00 % in Miller I and 60.73 ± 37.90 % in Miller III. The width of clinical attachment loss of keratinized tissue was significantly improved. Conclusions. VISTA and SCTG are effective in the treatment of both Miller class I and III multiple gingival recessions. Gingival increment in Miller class I is better than that in III. It is the same for maxillary and mandibular teeth.

Highlights

Multiple gingival recession (GR) is a common clinical symptom after the destruction of periodontal tissues, which causes gingival apical displacement and exposure of the cementoenamel junction
It can be seen that the GD of Miller class I decreased from 1:54 ± 0:71 mm to 0:02 ± 0:10 mm (P < 0:05), and the average root coverage (RC) was 1:52 ± 0:70 mm
The average RC rate was 99:00% ± 5:00%, and 24 of Comparing the gingival changes of Miller I and III between preoperation and postoperation, Table 2 showed that the RC including width and depth of Miller I was more than that of Miller III, as well as clinical attachment loss (CAL) change

Summary

Introduction

Multiple gingival recession (GR) is a common clinical symptom after the destruction of periodontal tissues, which causes gingival apical displacement and exposure of the cementoenamel junction. It is defined as gingiva receding in successive teeth and often leads to sensitive root surface exposure, root surface caries, and wedge-shaped defects and affects the therapeutic effect of the esthetic area, in those patients with gummy smile. Traditional surgical methods for treatment of gingival recession defects include coronally advanced flap (CAF) and laterally advanced flap (LAF) [5]. With the development of microsurgical instruments and materials, the technique is improved to modified coronally advanced tunnel (MCAT)+SCTG after many periodontal experts completed researches [1, 2, 10, 11]
