药物成份或治疗方案详述:

纳入受试者并分组后,按照以下流程进行操作: 1.术前对受试者进行口内检查,面扫(放松面相、微笑面相、大笑面相),口扫,CBCT拍摄,DSD设计,mock up,数字化种植方案设计。 2.试验组(动态导航组):根据受试者术区情况在导航软件内利用术前CBCT、口扫信息、理想修复体信息进行数字化种植设计,术前进行手机定位器和参考板的标定,术区和术前设计CBCT进行配准,常规术前服用抗生素、消毒、局麻、翻瓣后,微创拔除无法保留的患牙后,充分搔刮拔牙窝,生理盐水冲洗清除炎性组织,备洞后在拔牙窝内植入种植体。若需要进行同期骨增量,则于跳跃间隙填充颗粒状同种异体骨混合自体骨屑,表面覆盖Bio-gide胶原膜。旋上愈合帽或临时修复体,减张缝合。对照组(静态导板组):根据受试者术区情况进行数字化种植设计,设计观察窗、固位钉套筒,生成数字化手术导板数据,打印制作导板,送冷消留手术备用。常规术前服用抗生素、消毒术区、局麻、翻瓣后,确认导板完全就位后,植入固位钉,在导板引导下植入种植体。若需要进行同期骨增量,则于跳跃间隙填充颗粒状同种异体骨混合自体骨屑,表面覆盖Bio-gide胶原膜。旋上愈合帽或临时修复体,减张缝合; 3.术后即刻拍摄CBCT, 对完成种植体植入精度测量、统计分析的研究人员设盲; 4.术后两周拆线; 5.若未同期进行骨增量手术,则术后三月复查、二期手术以及后续最终修复; 6.若同期进行骨增量手术,则术后六月复查、二期手术以及后续最终修复; 

Description for medicine or protocol of treatment in detail:

1. Preoperative oral examination, face scan (relaxed face, smiling face, laughing face), intra-oral scan, CBCT, DSD design, mock up and digital implant design are performed on the subjects. 2. Experimental group (dynamic navigation group) : Preoperative calibration and registration procedure is completed. Tooth extraction and implant surgery are performed under the guidance of dynamic navigation system guidance; Control group (static template group) : Preoperative fixation of static template in patient's mouth is completed. Tooth extraction and implant surgery are performed under the guidance of static template guidance; 3. CBCT is taken immediately after surgery, and researchers who complete the measurement and statistical analysis of implant implantation accuracy were blinded; 4. Stitches are removed two weeks after surgery; 5. If bone augmentation surgery is not performed at the same time, after three months subsequent restoration will be performed; 6. If bone augmentation surgery is performed at the same time, six months after the surgery, restoration procedure will be performed;

随机方法(请说明由何人用什么方法产生随机序列):

随机分组方案的产生:采用区组随机化设计,将进入研究的时间相近的4位受试者分为一个区组,根据进入研究的时间对受试者进行编号。由特定的人员在纳入受试者前生成随机分组序列,该人员仅参与随机分组方案生成和方案隐藏过程,不参与后续的临床研究。该人员利用EXCEL程序生成6组随机数字,每组4个随机数字,数字随机范围为0-100,数值较大的2个为试验组,较小的两个为对照组(例:第一区组中生成随机数字为66、32、1、78,则第一组1号和4号受试者进入试验组,3号和4号受试者进入对照组),若存在随机数字相同的情况,则再次生成随机数字。 随机分组方案的隐藏,将分组方案编号,并放入密封、不透光的信封中。每纳入完一个区组的受试者后,才能打开该区组的信封,按信封内的分组方案进行分组。

Randomization Procedure (please state who generates the random number sequence and by what method):

Generation of randomization scheme: Block randomization design is adopted to divide the 4 subjects who enter the study at similar time into a block group, and the patients are numbered according to the time they enter the study. The randomization sequence is generated by a specific person before the inc
