研究目的: |
通过对残根残冠患者分别随机行3D打印个性化金属桩核、纤维桩核、个性化PEEK桩核修复,修复完成后每6、12个月评估桩核修复体的存活状况、功能状态和患者的主观满意度,最终建立PEEK桩核修复体的数字化标准化设计/制作指南,并为不同牙本质高度的残根残冠修复中桩核材料与修复设计方式的选择提供依据。 |

|
Objectives of Study: |
This study involves the randomized assignment of patients with residual roots and crowns to receive restorations using 3D-printed customized metal posts and cores, fiber posts and cores, or customized PEEK posts and cores. The survival rate, functional performance, and patient-reported satisfaction of the restorations will be assessed at 6 and 12 months post-treatment. The findings aim to develop a standardized digital workflow for the design and fabrication of PEEK post-and-core restorations and to inform the selection of materials and design approaches for restoring residual roots and crowns with varying dentin heights. |

随机方法(请说明由何人用什么方法产生随机序列): |
在随机分配前,根据患者患牙牙本质壁数将患者分类,在每个类别下采用随机数表发将患者随机分配到对照组或实验组。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Prior to random allocation, patients will be classified based on the number of dentinal walls in the affected tooth. Within each category, participants will be randomly assigned to either the control or experimental group using a random number table |

是否公开试验完成后的统计结果: Calculated Results after the Study Completed public access: |
不公开/Private |
|
盲法: |
患者:患者不知道自己接受的是哪种治疗 临床评价者:临床评估者无法知道患者的组别,避免其主观判断影响研究数据 统计分析人员:分析数据时,研究人员不应知道哪个组是实验组或对照组,以防止选择性分析或数据偏倚 |
|
Blinding: |
Patients: Patients are unaware of the treatment they are receiving. Clinical evaluators: Clinical evaluators are blinded to the patient's group allocation to prevent subjective judgment from influencing the study data. Statistical analysis personnel: During data analysis, researchers should remain unaware of the group assignments to avoid selective analysis or data bias. |
