Augmentation with hydroxylapatite and vestibuloplasty in the atrophic maxilla with a flabby ridge.

Hydroxylapatite is used for maxillary ridge augmentation in combination with a submucous vestibuloplasty. Undermining and internal incision of the flabby ridge provides a tunnel for Hydroxylapatite insertion. After three weeks the augmented maxilla is stable enough for prosthetic treatment. Indications, technique and first year experience with 7 cases are described.
