随机方法(请说明由何人用什么方法产生随机序列):

研究一:统计专业人员按区组随机方法(Excel软件产生随机序列)产生30个信封,每个信封内装有修复体的试戴顺序信息。 研究二:统计专业人员按区组随机方法(Excel软件产生随机序列)产生60个信封,每个信封内装有受试者的分组信息。

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

Study 1: A random grouping scheme was studied, in which statistical professionals generated 30 envelopes using block randomization method (using Excel software to generate a random sequence), each containing information on the trial order of the restoration. Study 2: The random grouping scheme was generated by statistical professionals using block randomization method (using Excel software to generate random sequences) to generate 60 envelopes, each containing the grouping information of the subjects.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

研究一:患者不知晓临时修复体的制作方式,因此对患者使用盲法进行满意度评价;评价者不知晓修复体的制作方式, 研究二:影像学评价阶段,评估者不知晓术前设计方式,因此对评估者使用盲法。

Blinding:

Study 1: Patients were not aware of the method of making temporary restorations, so they were evaluated for satisfaction using a blind method; The evaluator is unaware of the method of making the restoration, Study 2: In the imaging evaluation stage, the evaluator was unaware of the preoperative design method, so a blind method was used for the evaluator.
