[Use of dense polycrystal particulate hydroxyapatite artificial bone implant in augmentation of deficient alveolar ridges].
The preliminary results of dense polycrystal particulate hydroxylapatite artificial bone implant procedures in a group of 14 mandibular alveolar ridges atrophy patient is reported. Clinical studies show that this material has very good biocompatibility. Subjective and objective data show that the implant was successful for all varieties of mandibular alveolar ridges, the height, bulk, contour, and ridge form were generally improved, and soft tissue overlying the augmented ridges was firm and immobile. Impressions for dentures were usually obtained 4-8 weeks after surgery, and the dentures were more stable, retentive, and esthetically pleasing than the preoperative ones. It is concluded that hydroxylapatite particles placed through a subperiosteal tunnel offer a highly successful method of ridge augmentation.
