Hydroxylapatite (H/A) particulate versus cones as post-extraction implants in humans. Parts I & II

Hydroxylapatite was evaluated in two separate parallel studies in humans as ridge maintenance implant materials. The techniques for the use of each, the methods of analyzing them and the postoperative results were reported and compared. Particulate H/A (20 mesh) served more reliably and predictably than the same material in cone form, when used in alveoli after dental extractions as an immediate grafting material for ridge maintenance in humans.
