Cohort study 

研究目的:

比较牙列缺损患者行种植多单位修复中采用桥Base基台和粘接基台修复的临床安全性和有效性,明确两种基台在临床疗效中是否差异;为桥Base基台在种植临床修复中的应用和基台选择提供理论依据。  

Objectives of Study:

This study comparatively evaluates the clinical safety and efficacy of titanium base abutments versus cement-retained abutments for multi-unit implant-supported fixed dental prostheses in patients with partial edentulism. The primary objective is to determine any significant clinical differences between the two abutment systems. These findings provide an evidence-based foundation for the optimal selection and application of abutments in implant rehabilitation.

测量指标:

Outcomes:

指标中文名:

边缘骨吸收

指标类型:

次要指标

Outcome:

Marginal Bone Loss

Type:

Secondary indicator

测量时间点:

戴牙2周、6月、12月

测量方法:

由同一位检查者在平行投照的X线片上测量种植体周围的骨吸收量,测量位点包括每颗种植体的近中和远中,最终选取骨吸收量最严重的位点作为该种植体的骨丧失值。

Measure time point of outcome:

6 months, and 12 months after prosthesis delivery

Measure method:

Peri-implant bone resorption was measured by the same examiner on parallel radiographs. Measurements were taken at the mesial and distal aspects of each implant. The site with the most severe bone resorption was selected as the value representing bone loss for that implant.

指标中文名:

满意度

指标类型:

次要指标

Outcome:

Satisfaction

Type:

Secondary indicator

测量时间点:

戴牙2周、6月、12月

测量方法:

患者在戴牙后2周、6月、12月填写口腔健康相关生活质量(OHIP14)评分量表,在戴牙12月时填写视觉模拟评分量表,医生在戴牙12月填写种植修复功能评分表(FIPS)。

Measure time point of outcome:

2 weeks, 6 months, and 12 months after prosthesis delivery

Measure method:

Patients completed the Oral Health Impact Profile (OHIP-14) questionnaire at 2 weeks, 6 months, and 12 months after prosthetic delivery. The Visual Analog Scale (VAS) was completed by patients at the 12-month follow-up. The Functional Implant Prosthetic Score (FIPS) was assessed by the clinician at the 12-month interval.
