title: Hydroxylapatite alveolar ridge reconstruction: clinical experiences, complications, and technical modifications.
abstract: Results of the reconstruction of 228 deficient alveolar ridges (208 patients) using hydroxylapatite with or without autogenous cancellous bone over a six-year period are reported. Complications included erosion, mental nerve neuropathy, migration and displacement of particles, overfill, and loose material. Modified techniques are presented that minimize the occurrence of these complications in Class III and IV ridge-deficient patients.
