研究目的:

本研究拟通过随机对照研究,研究黏性骨在第三磨牙拔除后第二磨牙远中骨缺损修复中的效果,以牙周检查、影像学骨密度、患者术后反应为核心测量指标,为临床决策提供循证依据。  

Objectives of Study:

This study aims to evaluate the efficacy of sticky bone in the repair of distal bone defects of the adjacent second molar following mandibular third molar extraction through a randomized controlled trial. The core outcome measures will include periodontal examination, radiographic bone density, and patient-reported postoperative responses, in order to provide an evidence-based foundation for clinical decision-making.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机法。由不参与临床手术及评估的独立第三方统计员,利用计算机统计软件生成随机序列及对应的分组代码。

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

This study adopts block randomization. An independent third-party statistician, who is not involved in the clinical surgery or assessment, generates the random sequence and corresponding group codes using computer statistical software.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

本研究采用双盲设计。为实施盲法,干预措施(实验组与对照组所用材料)由不参与研究的药剂师/技术人员根据随机分组代码提前准备,确保其外观、包装、使用方法(如注射器规格、操作步骤)完全一致。所有材料以相同编号的密封套件形式提供。研究过程中,受试者、负责手术的外科医生、术后评估的检查者及数据分析师均对分组不知情。仅不参与临床流程的统计员持有盲底。仅在发生严重不良事件且必须知晓干预内容以进行医疗处理时,方可由主要研究者申请紧急揭盲,并详细记录原因。整个研究的数据录入与初步分析均在盲态下完成。

Blinding:

Concealed Allocation Method: A computer-generated block randomization sequence is maintained by an independent third-party statistician not involved in recruitment, surgery, or assessment. After eligible participants complete the baseline assessment, the investigator contacts this statistician via telephone or an online system. The statistician provides a unique group code in real-time based on the pre-generated sequence, and the investigator executes the corresponding protocol accordingly. The allocation information is kept confidential from the investigators, participants, and assessors throughout the study.
