Comparative Analysis of VISTA and minimum invasive intrasulcular Tunnelling Technique Using Tuberosity Graft Versus VISTA and intrasulcular Tunnelling Combined with Palatal Subepithelial Connective Tissue Grafts in multiple gingival recession coverage with Split-Mouth Design: An Original Investigation

Objective: To compare the clinical outcomes of Vestibular Incision Subperiosteal Tunnel Access (VISTA) tunnelling technique using tuberosity grafts versus VISTA tunnelling combined with palatal SCTG graft in the treatment of Miller’s class I and class Il gingival recession in a patient with maxillary anterior left and right region using a split-mouth design.
Materials and Methods: A 23-year-old male patient presenting with bilateral Miller’s Class I and Class Il gingival recession defects in the maxillary anterior left and right region was enrolled. Recession sites were randomly assigned to two groups:
VISTA tunnelling using tuberosity graft (test group) and VISTA tunnelling combined with palatal SCTG graft (control group).
Clinical parameters, including gingival recession depth (GRD), clinical attachment level (CAL), and keratinized tissue width (KTW), were measured at baseline and 6 months postoperatively. Patient-reported outcomes, such as pain and esthetic satisfaction, were assessed using a visual analogue scale (VAS).
Results: Both techniques showed significant improvements in CAL, RD, and KTW. However, the tuberosity graft group demonstrated reduced postoperative pain and donor site morbidity, while the palatal graft group achieved slightly superior root coverage percentages.
Conclusion: Both methods are effective for multiple recession coverage. The choice of technique may depend on clinical requirements and patient preferences, particularly regarding donor site morbidity and aesthetic outcomes.
