Controversy exists concerning the integrity of hydroxyapatite-coated implants over time. The Louisiana State University Oral and Maxillofacial Surgery Department studied data of 1,374 HA-coated implants that were placed from 1985 to 1991. Data were examined according to life-table survival, interval success rate, reasons for failure, and long-term effects. The rate of integration for HA-coated implants was found to be superior to that of noncoated, titanium implants. The HA-coated implants also showed excellent survival and function rates.
