研究目的:

牙周炎患者即刻种植和延期种植的长期临床效果比较尚不清楚,影响牙周炎患者即刻种植和延期种植效果的影响因素也不明确,本项目通过分析多种潜在影响因素对于牙周炎患者即刻种植和延期种植长期临床效果的影响,探索影响牙周炎患者即刻种植和延期种植效果的可能原因,同时比较即刻种植和延期种植的多种临床结局(种植体存活、种植体成功、边缘骨丧失(Marginal bone loss,MBL)等),从而确定即刻种植和延期种植的长期临床效果差异,明确可能影响二者种植效果的危险因素。  

Objectives of Study:

The comparison of long-term clinical outcomes between immediate and delayed implant placement in patients with a history of periodontitis remains unclear. Furthermore, the factors influencing the outcomes of immediate and delayed implant placement in these patients are not well-defined. This study aims to analyze the impact of various potential influencing factors on the long-term clinical outcomes of immediate and delayed implant placement in patients with a history of periodontitis, to explore the possible reasons affecting the outcomes, and to compare various clinical outcomes (e.g., implant survival, implant success, and marginal bone loss [MBL]) between immediate and delayed placement. Ultimately, this will determine the differences in long-term clinical outcomes between immediate and delayed implant placement and identify potential risk factors that may affect the outcomes of both techniques
