研究目的: |
1. 比较 RBH 2-4mm 采用不植骨内提升新技术与 RBH 4-6mm 采用不植骨骨凿法内提升术的临床效果; 2. 分析两种方案的种植体存活率、骨增量、种植体稳定性(ISQ 值)及并发症(黏膜穿孔、感染等)的差异; 3. 探讨不同 RBH 范围及手术技术对预后的影响,为临床术式选择提供参考。 |
||||||||||||||||||||||
|
Objectives of Study: |
1. To compare the clinical effects of the new non-bone grafting internal elevation technique with RBH 2-4mm and the non-bone grafting bone chisel internal elevation technique with RBH 4-6mm; 2. To analyze the differences in implant survival rate, bone gain, implant stability (ISQ value), and complications (such as mucosal perforation and infection) between the two schemes; 3. To explore the influence of different RBH ranges and surgical techniques on prognosis and provide a reference for the selection of clinical surgical methods. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
1、收集的患者病历资料(包括影像学数据、临床记录)采用匿名化处理,以编号替代姓名等身份信息。 2、数据录入采用双人盲法,录入后进行交叉核对,确保准确性。 3、所有数据存储于加密电脑,仅限研究人员访问,严格遵守医疗隐私保护法规。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The collected patient medical records (including imaging data and clinical records) were anonymized, with personal identifiers such as names replaced by study codes.Data entry was performed by two independent researchers in a double-blind manner, followed by cross-checking to ensure accuracy.All data were stored on an encrypted computer with access restricted to researchers only, in strict compliance with medical privacy protection regulations. |
