摘要
背景:珊瑚羟基磷灰石作为骨移植物的优点主要有安全性、生物相容性和骨传导性,所以对于许多临床适应证它可以作为一个替代骨的生物材料。目的:观察应用珊瑚羟基磷灰石于上颌切牙拔出后的牙槽窝后,对牙槽嵴的保持结果。方法:将11例患者的17个因创伤不可保存的上颌切牙拔除,拔除后即刻将珊瑚羟基磷灰石植入拔牙窝。植入后3个月对患者进行临床观察和口腔全景X射线片检测。结果与结论:所有患者均无不良反应和体征。X射线研究发现珊瑚羟基磷灰石植入后3,6个月后在植入区有新骨形成,与周围的骨组织无明显界限,且保持了牙槽骨的高度。说明珊瑚羟基磷灰石可以有效保持脊拔牙后牙槽骨的高度,并能促进新骨形成。
BACKGROUND： The benefits of coralline hydroxyapatite as bone graft are predominantly its safety, biocompatibility and osteoconductivity. Therefore, it can be used as a substitution biomaterial for bone in many indications clinically.
OBJECTIVE： To observe coralline hydroxyapatite effects on maintaining alveolar ridge in the socket after extracting maxillary incisor.
METHODS： Seventeen un-savable maxillary incisors resulting from trauma in 11 patients were extracted and at the same time coralline hydroxyapatite was implanted in socket sites. The patients were subjected to clinical observation and oral panoramic radiographs detection at postoperative 3 months.
RESULTS AND CONCLUSION： All patients had no adverse symptoms and physical signs. X-ray findings suggested new bone formation in the implanted area with coralline hydroxyapatite at postoperative 3 and 6 months, the surrounding bone tissue had no obvious boundaries, and the height of alveolar bone was maintained. Socket preservation using coralline hydroxyapatite can effectively maintain ridge of alveolar bone following tooth extraction and can promote new bone formation.
