Postoperative Results of a Dental-Implant Technique for Missing Teeth with Alveolar Bone Fracture NOJIMA Junya, IMAI Kenichiro, TOMARU Yasuhisa, NAITO Minoru, SAKATA Yasuaki, ABE Takahiro, SHIMAMURA Yumiko, FUKUSHIMA Yosuke, KOBAYASHI Akio, YODA Tetsuya (Department of Oral and Maxillofacial Surgery, Saitama Medical School, Moroyama, Iruma-gun, Saitama 350-0495, Japan) (Chief: Prof. YODA Tetsuya) 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.
