摘　　要：目的比较即刻负荷种植修复与延期负荷修复的临床效果。方法选择60枚植入时转矩≥30Ncm的ITI种植体作为研究对象,随机分为两组,即刻负荷组30枚种植体在植入时即刻取模,制作临时冠,给予即刻负荷;延迟负荷组30枚种植体则安放封闭螺丝予延迟负荷作为对照。所有种植体4～6个月后予永久修复,并检测种植体周龈袋深度、出血指数、年累计骨吸收量及存留率。结果即刻负荷组2枚种植体脱落,存留率93.3%,延期负荷组1枚种植体脱落,存留率96.7%,二者差异无统计学意义。其龈袋深度、出血指数、年累计骨吸收量及X线检查均无明显不同。结论在严格掌握适应证的情况下,即刻负荷可以取得与延期负荷同样的成功率。Objective To evaluate the clinical effect of immediately loaded implants versus implants loaded in a delayed fashion. Methods Sixty ITI implants with good primary stability （torque≥30 Nem） were randomly classified into 2 groups according to different repair methods. One group was loaded immediately with temporary acrylic resin restorations after insertion of implants, and the other group was loaded delayedly. The final restorations were placed after 4 - 6 months, The clinical and radiography indexes （such as perioimplant gingival bleeding index, probing depth, survival rate and bone resorption） were measured. Results Two implants lost in immediate loading group and 1 implant lost in delayed restoration group, with the survival rate 93.3% and 96.7 % respectively. There were no significant difference between the two groups. Conclusion Only if operation indications were held strictly, immediate loading still had a high success rate as such as delayed restoration.
