研究目的: |
主要研究目的 以“上颌第一磨牙近中位移(mm)”为主要终点指标,评估与比较PASS矫治系统与标准MBT、Damon直丝弓矫治系统(允许使用辅助支抗装置)在正畸治疗(拔除第一前磨牙病例)中,对上颌第一磨牙矢状向控制的临床效果,验证PASS矫治器的支抗控制优势。以PASS矫治器的主要终点指标作为因变量,结合牙列特征、骨性特征及人群特征进行相关性分析,明确影响PASS矫治疗效的关键因素,筛选PASS矫治器的优势人群,并阐明优势人群的核心特征。 次要研究目的: 评估与比较不同矫治系统对上颌前牙(中切牙)内收量、转矩变化的影响。 评估与比较不同矫治系统对其他牙齿(如尖牙)三维位置变化(矢状向、垂直向、轴倾度、转矩)的影响。 评估不同矫治系统的治疗效率(如总疗程时间、复诊次数)。 评估与记录不同矫治系统在治疗过程中的不良事件(如牙根吸收、牙周问题、托槽脱落率、患者疼痛与不适感等)。 |

Objectives of Study: |
Main research purposeTaking "near-middle displacement (mm) of the maxillary first molar" as the primary endpoint indicator, the clinical effects of the PASS orthodontic system, standard MBT, and Damon straight wire arch orthodontic system (allowing the use of auxiliary brace devices) on sagittal control of the maxillary first molar in orthodontic treatment (cases of first premolar extraction) were evaluated and compared. Verify the anchorage control advantages of the PASS orthodontic appliance. Taking the primary endpoint indicators of the PASS orthodontic appliance as the dependent variable, a correlation analysis was conducted in combination with dental arch characteristics, bony characteristics and population characteristics to clarify the key factors affecting the therapeutic effect of PASS orthodontic treatment, screen the dominant population of PASS orthodontic appliances, and clarify the core characteristics of the dominant population.Secondary research objectives:Evaluate and compare the effects of different orthodontic systems on the adduction amount and torque changes of the maxillary anterior teeth (central incisors).Evaluate and compare the effects of different orthodontic systems on the three-dimensional positional changes (sagittal, vertical, axial tilt, torque) of other teeth (such as canines).Evaluate the treatment efficiency of different orthodontic systems .Evaluate and record adverse events during the treatment process of different orthodontic systems. |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
After the subjects were screened, Dr. Dai Jingtao recorded stratified factors such as their age, gender, and antibiotic support needs to generate unique identifiers. Through a central randomization system, a random sequence is generated based on stratification factors. |

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: |
本研究的数据采集和管理工作由 病例记录表(Case Record Form, CRF)与电子采集和管理系统(Electronic Data Capture, EDC)两部分构成,其中EDC选择ResMan临床试验公共管理平台 http://www.medresman.org.cn/login.aspx,依托二者协同完成全周期临床研究数据的标准化采集、质控、存储与追溯管理,保障数据真实、完整、合规,符合临床研究方案及相关规范要求。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
The data collection and management of this study were composed of two parts: the Case Record Form (CRF) and the Electronic Data Capture (EDC) system. The EDC system selected was the ResMan clinical trial public management platform (http://www.medresman.org.cn/login.aspx). Relying on the collaboration of these two, the standardized collection, quality control, storage, and traceability management of clinical research data throughout the entire cycle were accomplished, ensuring the authenticity, completeness, and compliance of the data, in line with the clinical research protocol and relevant regulations. |
