摘要

目的珊瑚羟基磷灰石(CHA)较Bio-oss骨粉材料无免疫原性,无传播疾病风险,材料来源广泛,价格低廉。文中旨在研究CHA用于上颌前牙区位点保存的临床效果。方法选择2015年8月至2017年2月马鞍山市人民医院口腔科临床诊断为慢性牙周炎或根尖周炎而拔除上颌前牙患者26例(上颌前牙26颗)。随机分为CHA组(CHA)和对照组(Bio-oss骨粉)。术后即刻和4个月行锥体束CT(CBCT)检查,比较分析2组唇侧牙槽嵴的垂直向和水平向骨吸收量。结果术后即刻和4个月CHA组和对照组的唇侧牙槽嵴宽度和高度均有下降,宽度下降值分别为(1.1±0.7)mm、(1.3±1.9)mm,高度下降值分别为(1.3±1.6)mm、(1.2±1.4)mm,2组宽度及高度下降值比较差异无统计学意义(P>0.05)。结论 CHA用于上颌前牙区位点保存的疗效与Bio-oss骨粉相近,是一种理想的植骨材料。
        Objective Coralline hydroxyapatite( CHA),in comparison with Bio-Oss bone meal,is a material with extensive resources but no immunogenicity or risk of disease-transmission. The aim of this article was to study the clinical application of CHA in ridge preservation in the maxillary anterior zone. Methods Twenty-six patients underwent extraction of maxillary anterior teeth( n =26) for chronic periodontitis or periapical periodontitis. The patients were randomly assigned into a CHA and a control group of equal number to receive ridge preservation with CHA and Bio-Oss bone meal respectively. Cone beam computed tomography( CBCT) was performed immediately and at 4 months after ridge preservation to compare the vertical and horizontal alterations of the alveolar ridge between the two groups of patients. Results After ridge preservation,both the CHA and control groups showed a reduction in the width( [1.1±0.7]vs [1.3±1.9]mm) and height of the alveolar ridge( [1.3±1.6]vs [1.2±1.4]mm),but with no statistically significant differences between the two groups( P<0.05). Conclusion For ridge preservation in the maxillary anterior zone,CHA has a similar effect to that of Bio-Oss bone meal and therefore is an ideal material for bone graft.
