The purpose of dental implant therapy is to restore functions of mastication or speech, facial appearance, and health. Esthetics
must also be considered a critical factor for implantation on anterior region. In patients with severe periodontitis or periimplantitis,
there is often insufficient keratinized mucosa. In that case, the“ pink esthetics”of the implant restoration is expected to
be poor as well as the maintenance of the oral hygiene.
In this case report, free gingival graft (FGG) was conducted in order to increase the keratinized mucosa after removal of failed
implant in anterior mandible. Although insufficient keratinized mucosa may not always lead to poor oral hygiene, gingival
recession or crestal bone loss, adequate amount of keratinized mucosa may be needed for better plague control and esthetics. After
soft tissue management with FGG, implantation and guided bone regeneration (GBR) was conducted simultaneously. The final
restoration was delivered after osseointegration. Simultaneous approach of implantation and GBR was chosen for hard tissue
augmentation, considering the low lip line and bone level of adjacent teeth and implants.
The patient was satisfied with the final restoration. For good long term outcome, the periodic follow-up recalls will be
