研究目的: |
针对后牙需要联冠修复且有一个基牙为活髓牙的患者,设计并制作了在牙合面用特殊颜色指示髓腔位置的联冠,以便后续根管治疗时可以在引导下直接开髓而不必拆除联冠。 |
||||||||||||||||||||||
|
Objectives of Study: |
For patients who require combined-crown restorations on posterior teeth, particularly when one of the abutment teeth has a vital pulp, a custom combined-crown was designed and fabricated with a color indicator on the occlusal surface to mark the pulp chamber’s location. This design facilitates direct access to the pulp during subsequent root canal treatment, eliminating the need to remove the crown for access. |

纳入标准: |
1.18周岁以上,70周岁以下,无修复禁忌证; 2.相邻的两个磨牙需冠修复,同时因存在食物嵌塞或松动而适合联冠修复; 3.两个基牙中至少有一个为活髓牙; 4.资料完整,包括修复前的CBCT和牙备后的口扫取模。 |
||||||||||||||||||||||
|
Inclusion criteria |
1. Patients aged 18 to 70 years, with no contraindications for restoration. 2. Both adjacent molars require crown restoration and are suitable for a combined-crown due to food impaction or mobility. 3. At least one of the abutment teeth must have a vital pulp. 4. Complete documentation, including pre-restoration CBCT scans and digital impressions taken after tooth preparation, is required. |
||||||||||||||||||||||
|
排除标准: |
1.未控制的糖尿病、牙周炎,吸烟量≥20根/天,严重的错合畸形或不良咬合习惯(偏侧咀嚼、夜磨牙等); 2.修复前CBCT显示髓腔形态变异大或钙化严重; 3.拒绝加入本研究。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. Uncontrolled diabetes, periodontitis, smoking of ≥ 20 cigarettes per day, severe malocclusion, or harmful occlusal habits (e.g., unilateral chewing, bruxism). 2. Pre-restoration CBCT revealing significant variations in pulp chamber morphology or severe calcification. 3. Refusal to participate in the study. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
由主要研究者对患者进行记录和编号,其知晓患者的身份识别信息,但不参与后续的数据采集和分析。由其他研究者根据患者的资料进行数据采集和分析,其不知晓患者的身份识别信息,仅通过编号区分患者。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The primary investigator records and assigns identification numbers to the patients, maintaining awareness of their identity information, but refrains from participating in subsequent data collection and analysis. Other researchers, who are blind to the patients' identity information, conduct the data collection and analysis using the patients' records, distinguishing them solely by the assigned numbers. |
