A new flap design, the coronally positioned palatal sliding flap, was used to cover barrier membrane placed over implants in one patient, and to provide localized ridge augmentation around implants in another patient. The method is a valid surgical approach because of the favorable risk-benefit ratio. The surgical technique is easy to perform, and it is possible to obtain a sufficient positio nof the palatal tissue. This new palatal flap design may indicated for a variety of implant surgery.
