Abstract
Background and Aim: This study compared the efficacy of acellular dermal matrix (ADM) with and without injectable platelet-rich fibrin (iPRF) and free gingival graft (FGG) for the enhancement of peri-implant keratinized gingiva width (KGW).
Materials and Methods: In this randomized controlled clinical trial, 36 dental implants with KGW<2 mm were randomly assigned to 3 groups (n=12) for enhancement of KGW with FGG alone (control group), ADM alone (AlloDerm), and iPRF-impregnated ADM (AlloDerm). KGW, pain by using a visual analog scale (VAS), and graft shrinkage percentage (reduction in height and surface area of the graft) were assessed 3 months after surgery, and compared by one-way ANOVA and Sidak test (alpha=0.05).
Results: A significant increase in peri-implant KGW was observed after treatment in all three groups (P<0.001). FGG caused a significantly greater increase in KGW than the other two groups (P<0.001). Graft shrinkage was significantly lower in the FGG group than other groups (P<0.05). Postoperative pain was significantly lower in the ADM/iPRF than the FGG (P<0.001) and ADM (P=0.002) groups. Postoperative pain in the ADM group was significantly lower than that in the FGG group (P=0.008). No other significant differences were found (P>0.05).
Conclusion: All three tested methods significantly increased the peri-implant KGW. Although FGG was the most effective for the enhancement of KGW, it was associated with the highest postoperative pain level. IPRF-impregnated ADM may be considered as an acceptable, less invasive, and less painful approach for patients not consenting to FGG, although it had no significant difference with ADM alone.
