歯槽骨外傷後のデンタルインプラント術後成績

摘要

We evaluated the implant treatment for missing teeth accompanied with an alveolar bone fracture due to trauma. Eight patients were treated with dental implants (AQB system®). In general, for the success of the implant treatment a suitable implant insertion site in the bone is necessary. However, it was difficult to accurately determine the site for the placement of implants since the alveolar bone has a sharp and spiny ridge. To evaluate the postoperative state of implants, imaging diagnosis was used. Dental implantation was established with osseointegration and was fixed in the narrow bone space by cross-sectional CT imaging. Since its osseointegration grew in early period, we recognized the hydroxyapatite (HA)-coated implant system was suitable for narrow bone space for its insertion. However, in some cases, alveolar ridge augmentation becomes necessary when severe bone loss has occurred.
