Abstract
|
|
|
The one of peri-implant soft tissue problems seen during the maintenance phase of implant therapy is an inadequate
zone of keratinized tissue. Keratinized tissue plays a major role around teeth and dental implants, helping in maintaining
and facilitating oral hygiene. A free gingival graft (FGG) is chosen to correct the soft tissue defects and provide optimal
peri-implant health in order to increase the long-term prognosis of the implant reconstruction. However, the patient
treated with FGG has pain and discomfort on donor site such as palate. It is also technically demanding, time consuming,
and the color match of the tissue is often less than ideal.
An apically positioned flap (APF) is selected for increasing the keratinized tissue simply while or after the second stage
implant surgery. This case report shows successfully increasing the width of peri-implant kenratinized tissue through
APF procedure on small site of dental implant instead of FGG.
