研究目的:

探索新型低剂量缓释BMP2缓释磷酸钙材料临床修复牙槽突裂的疗效:CBCT分析植骨区成骨体积、密度、高度、厚度、尖牙萌出等情况,评估新型低剂量缓释BMP2缓释磷酸钙材料促进牙槽突裂植骨修复临床效果,为多中心临床应用提供实践依据。  

Objectives of Study:

To investigate the clinical efficacy of a novel low-dose sustained-release BMP-2 calcium phosphate material in the repair of alveolar clefts. Cone-beam computed tomography (CBCT) will be used to analyze bone volume, density, height, thickness, and canine eruption in the grafted area, so as to evaluate the material’s ability to promote alveolar cleft bone regeneration. The findings are expected to provide practical evidence for future multicenter clinical application.

盲法:

本研究开始前,由申办单位(或合同研究组织)会同统计人员进行统一编盲。由本次研究中的统计人员,在计算机上利用统计软件,按分层区组随机的方法产生随机编码表。由与本临床研究的临床观察、监查无关的人员,根据已形成的随机处理编码将相应的编号放在不透明的信封中。 产生的全部处理编码,包括编码所对应的组别、产生随机编码的种子数等参数所形成的盲底密封起来,交由申办单位和临床研究负责单位保存,该盲底应妥善保存至临床研究结束后。

Blinding:

Before the initiation of this study, a unified blinding procedure will be performed jointly by the sponsor (or contract research organization) and the statisticians. The statisticians involved in this study will generate a randomization code list using statistical software on a computer, employing a stratified block randomization method. Personnel not involved in clinical observations or monitoring of this trial will place the corresponding allocation numbers into opaque envelopes according to the pre-generated randomization codes. All generated treatment codes, including the group assignments corresponding to each code and parameters such as the seed number used for generating the randomization list, will be sealed as the master randomization file. This sealed file will be stored securely by both the sponsor and the institution responsible for conducting the clinical study, and must be retained appropriately until the completion of the trial.
