Abstract

Purpose

This study aimed to evaluate the condylar volume of growing patients after rapid maxillary expansion (RME) by Haas and Hyrax appliances.

Methods

This retrospective cross- sectional study assessed the records of patients diagnosed with transversal maxillary deficiency and with incomplete maturation of midpalatal suture. RME was performed with Haas or Hyrax appliances. Condylar volume was obtained by segmentation of DICOM images from cone-beam computerized tomographys before (T1) and after one year (T2) of RME. The results were compared between the experimental times, sex, and appliances by parametric tests (alpha = 5%).

Results

Twenty-seven patients were included (128 ± 21 months old). There were no statistical differences in condylar volume between experimental times (T1 and T2), sex, and appliances to the right and left condyle (P > 0.05).

Conclusion

RME by Haas or Hyrax does not impact the condylar volume of growing patients.

生长患者Haas和Hyrax快速上颌扩张后髁突体积的比较：一项回顾性横断面研究

目的研究Haas和Hyrax矫治器快速上颌扩张（RME）后成长期患者的髁突体积。方法回顾性分析上颌横向缺损和中腭缝合不完全成熟患者的临床资料。RME采用Haas或Hyrax器械。髁突体积是通过分割锥形束计算机断层扫描的DICOM图像在RME之前（T1）和之后一年（T2）得到的。通过参数检验（alpha = 5%）比较实验时间、性别和器具之间的结果。结果纳入患者27例（年龄128±21个月）。实验时间（T1和T2）、性别、左右髁矫治器在髁突体积上无统计学差异(P >；0.05)。结论Haas或Hyrax rme对成长期患者髁突体积无影响。
