title: Long-term evaluation of porous hydroxyapatite blocks for alveolar ridge augmentation.
abstract: Eleven patients, with a combined total of 14 atrophic edentulous ridges, underwent subperiosteal ridge augmentation with porous hydroxyapatite blocks. Clinical evaluation was continued for 4.5 to 6.5 years. All patients suffered long-term complications. The authors recommend that this material not be used for this purpose in the future.
