研究目的: |
(1)对种植单冠修复患者进行三年随访,定量分析修复后局部牙列咬合接触和邻接触随时间的长期变化,明确变化规律。 (2)探索种植单冠修复后邻接触丧失的风险因素,进一步分析咬合接触点分布、方向与邻接触丧失之间的相关性,为优化相关并发症的风险评估及临床应对策略提供理论依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
(1) Perform a 3-year longitudinal study on implant single crowns, quantifying long-term dynamic changes in occlusal and proximal contacts to characterize their temporal evolution. (2) Identify risk factors for post-restoration proximal contact loss (PCL) and evaluate correlations between occlusal contact characteristics (distribution/vector) and PCL, establishing an evidence base for improved risk stratification and clinical management. |

Exclusion criteria: |
1. The adjacent teeth or opposite teeth of implant-supported single crown were implant prostheses; 2. No occlusal contact of the adjacent teeth of the implant crown; 3. Filling cusps exist in the opposite teeth of implant-supported single crown. 4. Uncontrolled periodontitis; 5. Temporomandibular joint disease; 6. If an adjustment was made to change the local occlusion distribution or the adjacent contact after tooth wearing, such as crown restoration or occlusal surface filling to change the occlusal force distribution, or proximal resin filling to change the adjacent contact, the adjustment time was set as the end point of follow-up. |

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: |
结合既往文献和统计学专家意见,制作专用检查表和检查表代码说明,经过严格培训的指定医师管理患者随访,定期联系,制定随访计划,保证能尽可能观察到所需要的数据。根据受试者的原始观察记录,及时、完整、正确、清晰地填写原始数据,并录入采用相应的数据库系统。原始数据在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,妥善保存,防止损坏。如果纳入研究的患者在研究过程中拒绝进一步的参与或者在随访时联系不到,那么该患者将退出研究。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Based on previous literature and statistical expert opinions, a dedicated checklist and codebook were developed. Specially trained physicians were assigned to manage patient follow-ups, maintain regular contact, and implement follow-up plans to ensure optimal data collection. All observed data were recorded promptly, completely, accurately, and clearly in the original case report forms (CRFs) and entered into the designated database system. After verification, the original data were archived sequentially by ID number with retrieval indexes and stored securely to prevent damage. Patients who withdrew consent during the study or were lost to follow-up were considered study dropouts. |
