Abstract

OBJECTIVE

To compare the cephalometric characteristics of children with Class III malocclusion to those of children with normal occlusion during the deciduous dentition phase.

MATERIALS AND METHODS

Cephalometric measurements of 27 children (mean age: 5.03 years) diagnosed with Class III malocclusion were compared with 32 children (mean age: 4.85 years) diagnosed with normal occlusion in the following four categories: sagittal skeletal analysis, vertical skeletal analysis, dentoalveolar analysis, and soft tissue analysis.

RESULTS

Significant differences were seen in all categories except vertical skeletal analysis. Sagittal skeletal measurements included ANB (Class III group: -0.91 +/- 1.60; normal group: 5.28 +/- 1.29), facial convexity (Class III group: 0.47 +/- 4.32; normal group: 13.65 +/- 3.44), Wits appraisal (Class III group: -5.54 +/- 2.36; normal group: -0.84 +/- 1.91), and A to N-perpendicular (Class III group: -2.94 +/- 3.05; normal group: 0.78 +/- 2.53). Dentoalveolar measurements included U1 to NA (Class III group: 11.98 +/- 5.25; normal group: 8.12 +/- 5.43), IMPA (Class III group: 81.34 +/- 7.40; normal group: 86.57 +/- 5.67), and interincisal angle (Class III group: 152.65 +/- 8.82; normal group: 145.03 +/- 7.34). Soft tissue measurements included soft tissue convexity (Class III group: 2.47 +/- 4.20; normal group: 12.71 +/- 3.95), nasofacial angle (Class III group: 22.68 +/- 4.22; normal group: 26.24 +/- 3.84), and upper lip to esthetic plane (Class III group: -0.65 +/- 2.74; normal group: 3.07 +/- 1.90).

CONCLUSIONS

There are significant differences between the craniofacial patterns of normal children and those of children with Class III malocclusion that can be identified with cephalometric analysis as early as the deciduous dentition phase.

摘要

目的

比较替牙期安氏 III 类错（牙合）畸形儿童与正常（牙合）儿童的头影测量特征。

材料与方法

对 27 例安氏 III 类错（牙合）畸形儿童（平均年龄：5.03 岁）进行头影测量，并与 32 例正常（牙合）儿童（平均年龄：4.85 岁）进行比较，分为以下四个类别：矢状骨分析、垂直骨分析、牙颌分析和软组织分析。

结果

除垂直骨分析外，所有类别均存在显著差异。矢状骨测量值包括 ANB（III 类组：-0.91 +/- 1.60；正常组：5.28 +/- 1.29）、面凸角（III 类组：0.47 +/- 4.32；正常组：13.65 +/- 3.44）、Wits 评价（III 类组：-5.54 +/- 2.36；正常组：-0.84 +/- 1.91）和 A 点至 N 点垂线（III 类组：-2.94 +/- 3.05；正常组：0.78 +/- 2.53）。牙颌测量值包括 U1 至 NA（III 类组：11.98 +/- 5.25；正常组：8.12 +/- 5.43）、IMPA（III 类组：81.34 +/- 7.40；正常组：86.57 +/- 5.67）和切牙间角（III 类组：152.65 +/- 8.82；正常组：145.03 +/- 7.34）。软组织测量值包括软组织凸度（III 类组：2.47 +/- 4.20；正常组：12.71 +/- 3.95）、鼻面角（III 类组：22.68 +/- 4.22；正常组：26.24 +/- 3.84）和上唇至审美平面（III 类组：-0.65 +/- 2.74；正常组：3.07 +/- 1.90）。
