Inclusion criteria |
(1) Full body examination: in good physical condition, excluding major systemic diseases; maxillofacial examination: no history of maxillofacial surgery, no jaw cysts or tumors; oral examination: permanent dentition, teeth fully erupted, no dental defects, no congenital missing teeth, no history of orthodontic treatment. (2) Before treatment: Class I and/or II molar and cuspid relationships, dentally-induced protrusion, moderate or severe crowding in cases of tooth extraction (maxillary and mandibular crowding greater than 4 mm and less than 15 mm), mild crowding or scattered gaps in non-extraction cases (maxillary and mandibular crowding less than 4 mm, maximum remaining gap not exceeding 8 mm). After treatment: neutral relationship between the molars and cuspids, normal overbite and overjet, and teeth aligned without gaps. (3) Before treatment: X-ray cephalometry analysis: ANB angle between -5° and 8°, and the amount of bony protrusion or retrusion of the upper and lower jaws is less than 3mm. (4) The treatment period is less than 36 months, and the patient has given informed consent to the treatment process. |

|
排除标准: |
(1)正畸正颌联合治疗的病例,包括有正颌手术指征的病例(治疗前X线头影测量分析ANB角大于6°或小于-6°,上下颌骨骨性前突或后缩量大于3mm); (2)双期治疗的病例; (3)替牙期病例; (4)治疗周期大于36个月; (5)模型缺损或灌注的模型有气泡(直径大于2mm),病例资料不完整。 |
||||||||||||||||||||||
|
Exclusion criteria: |
(1) Cases of combined orthodontic and orthognathic treatment, including cases with indications for orthognathic surgery (pre-treatment analysis of the ANB angle by cephalometric X-ray is greater than 6° or less than -6°, and the amount of bony protrusion or retrusion of the upper and lower jaws greater than 3 mm); (2) cases of two-stage treatment; (3) cases of tooth replacement; (4) treatment cycle greater than 36 months; (5) model defects or bubbles (diameter greater than 2 mm) in the poured model, and incomplete case information. |

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: |
病例记录表 (CRF):通常包括患者的基本信息、病史、治疗过程和结果等。确保数据采集的一致性和完整性,便于后续的数据分析和研究。 电子采集和管理系统 (EDC):提供数据输入、验证、存储和导出功能,支持实时数据监控和管理。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Case Record Form (CRF): Usually includes basic information about the patient, medical history, course of treatment, and results. Ensures consistency and completeness of data collection and facilitates subsequent data analysis and research. Electronic Data Capture and Management (EDC) system: Provides data entry, validation, storage and export functions to support real-time data monitoring and management. |
