Abstract
Oral rehabilitation of the atrophic maxilla using prostheses anchored on zygomatic implants is a well-documented process. To prevent the risk of sinusitis and or oro-antral communications, the placement of zygomatic implants with an externalized path has been proposed. In these cases where the sealing of the implant neck depends exclusively on a hemidesmosomal junction, there is a risk of dehiscence of the soft tissue. This can lead to esthetic problems, bone resorption, oro antral communication, cellulitis, and even orbital infection. To avoid soft tissue recession when implants are placed in a buccal position to the remaining ridge, different procedures have been proposed, the simplest being a good buccal coverage of the implant by keratinized tissue. In this technical note, we propose the use of a double pedicle palatal flap to increase the keratinized tissue buccal to the implant and, at the same time, to facilitate the incision closure by initial intention.
