The Use of Three Dimensional Printed Hydroxyapatite Granules in Alveolar Ridge Preservation

Abstract:

In this study, an alveolar ridge preservation using novel hydroxyapatite granules which was fabricated by three dimensional printing technique in post-extraction socket was carried out and evaluated. Clinical, radiographic and histology were assessed prior to dental implant placement. Five volunteered patients who needed an extraction of anterior tooth and scheduled for implant replacement were enrolled in this pilot study. No sign of infection or local of systemic immune reaction to the three dimensional printed hydroxyapatite granules in all patients was noted. At 8 weeks post-surgery, the grafted area was observed to be completely filled with woven bone and the formation of new vessels was seen. In addition, the bone quality and quantity of the grafted site when placing the implant showed efficient implant stability (ISQ values ∼ 65) without the need of additional bone graft surgery. Overall results indicated that three dimensional printed hydroxyapatite granules could be potentially employed as bone grafting material for alveolar ridge preservation.
