The dentoalveolar compensation in different skeletal patterns of Iraqi adults

Abstract EN

Background : For different skeletal discrepancies, the maxillary and mandible incisors were inclined in normal incisor relationships as a result of dent alveolar compensatory mechanism.

The aims of this study were to compare the dent alveolar compensation among skeletal class I, skeletal class II, and skeletal class III jaw patterns, and to determine the gender difference in each class.

Materials and Methods : The patients’ history, clinical examination and Lateral Cephalometric radiographs were taken for 85 adult subjects.

According to ANB angle the sample classified into : 30 adult subjects skeletal class I (control samples), 30 adult subjects skeletal class II and 25 adult subjects skeletal class III (study samples), the Cephalometric radiographs are analyzed by using AutoCAD 2008 program.

Results and Conclusion: Sagittal jaw parameters show classes difference (by using ANOVA and LSD test) among different skeletal classes, vertical and dental parameters show gender and classes differences, while linear measurements show gender difference (by using independent t-test).

Dent alveolar compensation is affected by lower incisors in skeletal class II and by upper and lower incisors in skeletal class III.
