研究目的:

建立不同牙列阶段头影测量中正常腭高值对诊断上颌畸形和制定干预治疗方案至关重要。本研究旨在通过头影测量法确定中国人群的年龄和牙列特异性腭高参考范围,并通过牙模测量进行验证。  

Objectives of Study:

Establishing normative palatal height values on lateral cephalograms across different dentition stages is crucial for diagnosing maxillary dysmorphology and planning interventions therapy. This study aimed to define age- and dentition-specific palatal height reference ranges in Chinese population using cephalometry and validate them against dental cast measurements.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.无正畸或正颌治疗史。2.无影响颌面发育的颅面畸形或综合征。3.高质量侧位头影测量片,能清晰显示腭穹隆及周围结构。4.牙科石膏或数字化口腔内扫描中完整的腭形态,无任何缺陷。5.年龄范围 3 - 16 岁,覆盖目标牙列时期(乳牙列期、替牙列期、恒牙列期)。

Inclusion criteria

1. No history of orthodontic or orthognathic treatment. 2. No craniofacial anomalies or syndromes affecting maxillofacial development. 3. High-quality lateral cephalograms with clear visibility of the palatal vault and surrounding structures. 4. Complete palatal morphology in dental casts or digital intraoral scans without any defects. 5. Age range: 3 - 16 years, covering the target dentition periods (primary dentition, mixed dentition, permanent dentition).

排除标准:

1.颅颌面畸形或综合征。2.头影测量片模糊或者口扫模型腭部不全或者不清晰;

Exclusion criteria:

1. Craniofacial malformations or syndromes. 2. Blurred lateral cephalograms, or incomplete or unclear palatal regions in intraoral scan models.

Outcomes:

指标中文名:

腭穹隆高度

指标类型:

主要指标

Outcome:

Palatal Vault Height

Type:

Primary indicator

测量时间点:

乳牙列期,混合牙列期,恒牙列期

测量方法:

腭穹隆高度定义为从上颌第一磨牙(M1)近中尖端到上颌骨骨皮质(M2)与通过M1的垂直于咬合平面(OP)的交线之间的垂直距离。

Measure time point of outcome:

Primary Dentition Period, Mixed Dentition Period, Permanent Dentition Period

Measure method:

Palatal height was defined as the perpendicular distance from the most caudal point of the mesial cusp of the maxillary first molar (M1) to the intersection of the caudal cortex of the maxilla (M2) and the line perpendicular to the occlusal plane (OP) through M1.

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:

数据采集通过病例记录表进行,记录受试者的详细信息,包括牙颌模型和侧位头颅侧位片的腭穹隆高度测量值。数据管理由电子数据采集系统支持,以确保数据的准确性、完整性和及时录入。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection was performed using Case Record Forms (CRFs) to record detailed information of subjects, including palatal height measurements from dental casts and lateral cephalograms. Data management was supported by an Electronic Data Capture (EDC) system to ensure data accuracy, integrity, and timely entry.
