研究目的: |
1.测量分析上颌美学区理想龈缘中点到种植体唇侧延长线的垂线距离(Ideal Point-Implant,IPI)与修复后实际龈缘位置变化之间的相关性 2.根据相关性分析结果,确定获得理想龈缘的关键IPI数值范围,并根据该范围进行分组,比较IPI小与IPI大两组的修复后龈缘变化情况,使用研究结果指导美学区种植体唇腭向植入位置以获得更理想的修复后美学效果。 3.及时评估参加此项研究的受试者的种植牙周围软硬组织状况,并根据情况给予针对的种植牙维护指导,但本研究对受试者个体没有直接经济利益。 |

Objectives of Study: |
1. Correlation between the vertical distance from the ideal gingival margin midpoint to the labial extension line of the implant (Ideal Point-Implant, IPI) in the maxillary aesthetic zone, and changes in the actual gingival margin position post-restoration 2. Based on the results of the correlation analysis, determine the key IPI numerical range for achieving the ideal gingival margin, and group participants according to this range. Compare the post-restoration gingival margin changes between the low IPI and high IPI groups, and use the study results to guide the buccal-palatal implant placement in the aesthetic zone to achieve a more ideal post-restoration aesthetic outcome. 3. Timely assess the soft and hard tissue conditions around the implants of participants in this study and provide targeted implant maintenance guidance based on the situation. However, this study does not directly provide economic benefits to individual participants. |
