研究目的:

主要目的:比较脱蛋白猪骨粉(如Purgo THE Graft)与去蛋白牛骨粉(如Bio-Oss?)用于种植体周围炎骨缺损再生性手术后,两者在种植体周围边缘骨水平的维持效果。 次要目的:评估两种材料对探诊深度、出血等临床指标的改善效果;系统记录移植物暴露、感染等安全性事件;评估术后种植体的影像学骨结合稳定性;并收集骨缺损特征以及病变肉芽组织、唾液及种植体周龈沟液等关键生物样本,为后续构建临床预测模型奠定基础。  

Objectives of Study:

Primary Objective:? To compare the effects of deproteinized porcine bone mineral (e.g., Purgo THE Graft) versus deproteinized bovine bone mineral (e.g., Bio-Oss?) on the maintenance of peri-implant marginal bone level after regenerative surgery for peri-implantitis bone defects. Secondary Objectives:? To evaluate the improvements in clinical parameters such as probing depth and bleeding; to systematically record safety events including graft exposure and infection; to assess the radiographic implant stability; and to collect key data and biospecimens—including characteristics of the bone defects, as well as granulomatous tissue, saliva, and peri-implant sulcular fluid—for subsequent development of clinical predictive models.

指标类型:

主要指标

Outcome:

Peri-implant Marginal Bone Level Change

Type:

Primary indicator

测量时间点:

术前和术后6个月

测量方法:

通过标准化的数字化根尖X线片,测量种植体植入后(再生手术前)基线时与术后6个月时,种植体平台至骨缺损最根方骨嵴顶的垂直距离。计算差值作为骨水平变化值。

Measure time point of outcome:

Preoperative (baseline) and 6 months post-operation

Measure method:

Measured via standardized digital periapical radiographs. The vertical distance from the implant platform to the most apical crest of the bone defect is measured at baseline (before regenerative surgery) and at 6 months post-operation. The change in bone level is calculated as the difference between these two time points.

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:

本研究的所有数据将使用专门设计的病例报告表(CRF)进行采集。研究者或获得授权的研究人员需在每次访视后,将受试者的所有观察结果和检验数据如实、认真地填写至CRF中。 当CRF上的数据需要修改时,必须遵循特定的流程以确保数据的真实性和可追溯性。修改者不能涂抹或覆盖原始记录,而应在错误记录上划一条横线,使原记录仍清晰可辨,然后在旁边填写更正后的数据,并说明修改理由,最后由负责的研究医生签名并注明更正日期。 为确保数据的质量,将建立数据质疑机制。临床研究中所有观察到的结果和异常发现,都应及时加以认真核实。数据管理员或统计分析员在审核数据时,如果发现遗漏、存在逻辑错误或超出临床合理范围的数据,将通过“数据质疑表”的形式向研究中心发出质询。研究者需对数据质疑进行核对并给予书面回复和确认。 在研究结束时,所有CRF收集完毕并完成数据审核与质疑清理后,将进行数据库锁定。锁定的数据库将用于最终的统计分析。统计分析将按方案预定的分析计划,在指定的分析数据集(如全分析集FAS、符合方案集PPS、安全性分析集SS)上进行。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

All data in this study will be collected using specifically designed Case Report Forms (CRFs). The investigator or authorized research staff must accurately and conscientiously transcribe all observed outcomes and examination data into the CRFs following each study visit. When data on the CRF requires modification, a specific procedure must be followed to ensure data authenticity and traceability. The individual making the change must not obscure or overwrite the original entry. A single line should be drawn through the incorrect entry, preserving the legibility of the original data. The corrected value is then entered nearby, accompanied by the reason for the change. This correction must be signed (or initialed) and dated by the responsible investigating physician. A data query process will be implemented to ensure data quality. All observed results and abnormal findings in the clinical study must be promptly and thoroughly verified. During data review, if data managers or statistical analysts identify missing data, logical inconsistencies, or values falling outside clinically plausible ranges, they will issue a formal "Data Query Form" to the investigational site. The investigator is required to review each query and provide a written response and confirmation. Upon study completion, after all CRFs are collected and data review and query resolution are finalized, the study database will be locked. The locked database will be used for the final statistical analysis. The analysis will be performed according to the pre-specified statistical analysis plan on designated analysis sets, such as the Full Analysis Set (FAS), Per Protocol Set (PPS), and Safety Set (SS).
