研究目的: |
主要目的:评估单颗磨牙延期种植即刻修复与延期修复在种植体周围骨重建方面的效果差异,比较两者在骨水平变化中的临床疗效。 次要目的:评估即刻修复在种植体成功率、软组织健康(如龈乳头指数、角化龈宽度、探诊深度、出血指数等)、修复体美学效果、患者满意度及术后不适感、并发症发生率,以及在经济效益方面的表现。 |

Objectives of Study: |
Primary Objective: To evaluate the differences in peri-implant bone reconstruction outcomes between immediate restoration and delayed restoration of single molar delayed implants, and to compare their clinical efficacy in terms of bone level changes. Secondary Objectives: To assess the performance of immediate restoration in terms of: Implant success rate Soft tissue health (e.g., papilla index, keratinized gingiva width, probing depth, bleeding index, etc.) Aesthetic outcomes of the restoration Patient satisfaction and postoperative discomfort Incidence of complications Economic benefits |

|
盲法: |
采用单盲设计。虽然受试者和实施手术的医护人员知道具体的治疗分配,但结局评估者和数据分析者均对具体分组情况保持盲法,以减少评价偏倚。若在研究过程中出现紧急情况需要揭盲,则通过研究主管或独立的第三方进行处理,确保研究的完整性和受试者的安全。 |
|
Blinding: |
A single-blind design is adopted. While the participants and the medical staff performing the surgery are aware of the specific treatment allocation, the outcome assessors and data analysts remain blinded to the group assignments to minimize evaluation bias. In case of emergencies during the study that require unblinding, the process will be managed by the study supervisor or an independent third party to ensure the integrity of the study and the safety of the participants. |
