研究目的:

在该临床研究中,通过对比 SIM 单独使用及与 CGF 联合应用的临床疗效差异,追踪并评价其临床效果,进而进一步提升 CGF 和 SIM 在实际临床中的应用水平。根据空白对照组、明胶海绵+SIM 组、CGF+SIM 组的临床数据,系统分析单独使用 SIM 及 SIM 与CGF 混合应用对拔牙位点保存的效果差异,评估联合运用疗效,从而寻找一种简单可靠的,有助于减少患者拔牙后牙槽嵴吸收,降低患者经济负担,缩短种植手术等待时间并降低种植手术整体难度的更优方案。  

Objectives of Study:

In this clinical study, by comparing the differences in clinical efficacy between using SIM alone and in combination with CGF, the clinical effects were tracked and evaluated, thereby further enhancing the application of CGF and SIM in actual clinical practice. Based on clinical data from the blank control group, the gelatin sponge SIM group, and the CGF SIM group, a systematic analysis was conducted on the differences in alveolar ridge preservation effects between using SIM alone and in combination with CGF, evaluating the efficacy of combined use, in order to find a simple and reliable approach that helps reduce alveolar ridge resorption after tooth extraction, lowers patients' financial burden, shortens the waiting time for implant surgery, and reduces the overall difficulty of implant procedures.

随机方法(请说明由何人用什么方法产生随机序列):

用随机数生成软件(SPSS 26.0 版本, SPSS Inc., Chicago, IL, USA) 将患者按顺序编号后写于纸条上密封于不透光的信封中,拔牙前由一名不参与该项实验且完全不知情的医生打开信封抽取纸条,随机将患者纳入至牙槽嵴保存组或对照组中。

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

Using random number generation software (SPSS version 26.0, SPSS Inc., Chicago, IL, USA), patients were sequentially numbered and written on paper strips sealed in opaque envelopes. Prior to tooth extraction, a doctor who did not participate in the experiment and was completely unaware opened the envelope to extract the paper strips, and the patients were randomly assigned to either the alveolar ridge preservation group or the control group.
