Clinical Evaluation of Subepithelial Connective Tissue Graft Around Dental Implants

Objectives: Soft tissue profiles have critical importance in establishing optimal esthetics and maintenance of implant-supported restorations. The objective of the present study was to evaluate the efficacy of the subepithelial connective tissue graft technique (SCTG) in augmentation and improvement of soft tissue esthetics around dental implants in comparison to non- augmented implants in the esthetic zone.
Methods: Patients treated by SCTG (n=8) were compared to the control group after implant placement. Soft tissue thickness (STT) was assessed at 2, 4 and 6mm tissue depths at the study baseline, as well as 1,3, 6 and 9 months after prosthetic restoration.
For the surgical procedure palatal SCTGs were harvested and tucked in over the dental implants, followed by mucoperiosteal flap adaptation and suturing.
Results: Increased STT was measured in the SCTG group at all assessment periods and tissue depth levels. Statistically significant differences (Repeated measures ANOVA test; p<0.05) were obtained at 2mm level through the whole 9 months, at 4mm level after 1, 3 and 6 months and at 6mm level after 1 and 3 months (Table 1).
Conclusions: The following study showed that correct positioning and placement of implants with a simultaneous SCTG augmentation may provide an aid for improvement of soft tissue esthetics around dental implants in the esthetic zone.
