研究目的: |
本研究旨在通过前瞻性、单盲、多臂随机对照临床试验,比较改良数字化咬合板、传统数字化咬合板及单纯口服氨基葡萄糖治疗颞下颌关节骨关节炎(TMJOA)的临床疗效。主要评价三种干预方式在缓解关节疼痛方面的差异,次要评价其对最大张口度、关节弹响、扪诊疼痛、髁突骨质改变、复发率及患者满意度的影响,从而明确数字化咬合板,尤其是改良钛合金数字化咬合板,在TMJOA精准治疗中的有效性和安全性。 |

Objectives of Study: |
This study aims to compare the clinical efficacy of modified digital occlusal splints, conventional digital occlusal splints, and oral glucosamine alone in the treatment of temporomandibular joint osteoarthritis (TMJOA) using a prospective, single-blind, multi-arm randomized controlled trial design. The primary objective is to evaluate differences among the three interventions in relieving TMJOA-related pain. Secondary objectives are to assess changes in maximum mouth opening, joint clicking, palpation tenderness, condylar bone changes, recurrence rate, and patient satisfaction, thereby determining the effectiveness and safety of digital occlusal splints, particularly modified titanium alloy digital occlusal splints, for precision treatment of TMJOA. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用分层区组随机化方法。由不参与受试者招募、治疗实施及结局评价的统计分析人员使用计算机随机数字表生成随机分配序列。随机化按性别进行分层,采用3、6和9的随机排列区组,以1:1:1比例将符合条件的受试者分配至改良数字化咬合板组、传统数字化咬合板组或单纯氨基葡萄糖组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A stratified block randomization method will be used. A statistician who is not involved in participant recruitment, treatment implementation, or outcome assessment will generate the random allocation sequence using a computer-generated random number table. Randomization will be stratified by sex, with randomly permuted block sizes of 3, 6, and 9. Eligible participants will be allocated in a 1:1:1 ratio to the modified digital occlusal splint group, conventional digital occlusal splint group, or glucosamine-only group. |

|
盲法: |
本研究采用单盲设计。由于咬合板形态和治疗方式不同,受试者及治疗实施医生无法实施盲法;但负责结局评价、随访测量和数据统计分析的研究人员不参与干预实施,并在评价过程中不知晓受试者分组信息。主要结局VAS疼痛评分、最大张口度、关节弹响、扪诊疼痛及CBCT影像评价均由经培训的评估人员按照统一流程完成,以减少观察者偏倚。 |
|
Blinding: |
This study will use a single-blind design. Because the occlusal splints and treatment procedures differ among groups, participants and treating clinicians cannot be blinded. However, investigators responsible for outcome assessment, follow-up measurements, and statistical analysis will not be involved in treatment implementation and will remain blinded to group allocation. The primary outcome, VAS pain score, and secondary outcomes, including maximum mouth opening, joint clicking, palpation tenderness, and CBCT-based imaging assessment, will be evaluated by trained assessors using standardized procedures to minimize observer bias. |

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: |
本研究将采用标准化病例报告表(CRF)和电子数据表进行数据采集与管理。基线资料包括人口学信息、病史、DC/TMD诊断结果、颞下颌关节临床检查结果及CBCT影像资料;随访资料包括疼痛VAS评分、最大张口度、关节弹响、扪诊疼痛、依从性、不良事件、复发情况及患者满意度等。研究数据由经过培训的研究人员按照统一操作流程采集,并及时录入电子数据库。录入数据将与原始病历、检查记录、CBCT影像及随访记录进行核对。数据录入采用双人核查或由第二名研究者按比例抽查,以保证数据准确性和完整性。所有纸质资料保存于上锁文件柜,电子数据采用密码保护和加密备份,仅授权研究人员可访问。研究结束后,数据将以去标识化形式在研究机构指定安全区域保存至少5年。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Standardized case report forms (CRFs) and electronic data sheets will be used for data collection and management. Baseline data will include demographic information, medical history, DC/TMD diagnostic results, temporomandibular joint clinical examination findings, and CBCT imaging data. Follow-up data will include VAS pain scores, maximum mouth opening, joint clicking, palpation tenderness, treatment compliance, adverse events, recurrence, and patient satisfaction. Data will be collected by trained research staff according to standardized procedures and entered into an electronic database in a timely manner. Entered data will be checked against source medical records, examination records, CBCT images, and follow-up records. Data accuracy and completeness will be ensured through double checking or proportional verification by a second researcher. Paper documents will be stored in locked cabinets, and electronic data will be password-protected and backed up with encryption. After study completion, de-identified data will be stored in a secure area designated by the study institution for at least 5 years. |
