Implants that lack keratinized tissue (KT) have been associated with increased plaque accumulation, gingival inflammation or hue of metal showing through the tissue. Free gingival grafts (FGGs) are a predictable treatment for minimal or lack of KT. FGGs can increase the zone of KT around teeth and implants alike. Despite predictability of FGGs, stabilizing the graft around implants can be challenging, but is critical for success. Little information is available regarding ways to stabilize FGGs around implants. Acrylic or composite stents are a viable option for obtaining graft stability and support during the healing process.
This case report highlights the practicality of using acrylic or composite stents for FGG stabilization with successful outcomes. Two patients presented with dental implants, with minimal or lack of KT requiring soft tissue augmentation. FGGs were harvested from the palate and fitted around implant carriers allowing stabilization and adequate suturing. Custom-made acrylic or composite stabilization stents were fabricated to fit around implant carriers, which were screwed into the implant platform, and hollowed out internally to provide space for the graft. Postoperative visits showed healthy, stable zones of KT in both cases.
The customized acrylic or composite stents allowed stabilization of the FGGs with successful outcome.
