The aim of this study was to evaluate the changes in head posture, position of the hyoid bone, pharyngeal airway and cervical posture after the use of Petit type face mask in patients with skeletal class III malocclusion (ANB angle < 0) with ongoing growth. No other study was found in the literature in which head posture, cervical posture, and hyoid bone position were evaluated after the use of a face mask and compared with a control group consisting of patients of the same age group and the same malocclusion.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Craniocervical posture change | Investigation of the change in head posture after treatment of class III malocclusion due to maxillary deficiency with a face mask using craniocervical angles (NSL/CVT, NSL/OPT, CVT/HOR, OPT/HOR, NL/VER, NSL/VER). | Before treatment (T0) and after treatment (up to about 10-12 month; T1) for the study group. First measurement (T0) for the control group and after similar follow-up time (up to about 10-12 month; T1) as for the treatment group. | |
Primary | Pharyngeal airway change | Investigation of the change in pharyngeal airway dimensions after treatment of class III malocclusion due to maxillary deficiency with a face mask using pharyngeal airway sagittal dimension measurements (PNS-UPW, Cv2-MPW, Cv3-LPW, HRL/U-PNS, U-PNS, PASmin). | Before treatment (T0) and after treatment (up to about 10-12 month; T1) for the study group. First measurement (T0) for the control group and after similar follow-up time (up to about 10-12 month; T1) as for the treatment group. | |
Primary | Hyoid bone position change | Investigation of the change in hyoid bone position after treatment of class III malocclusion due to maxillary deficiency with a face mask using hyoid bone location measurements (H-Cv2, H-Cv3, H-Mandibular line, H-Me). | Before treatment (T0) and after treatment (up to about 10-12 month; T1) for the study group. First measurement (T0) for the control group and after similar follow-up time (up to about 10-12 month; T1) as for the treatment group. | |
Secondary | Correlation of craniocervical posture, pharyngeal airway and hyoid bone change | Investigation of the relationship between changes in craniocervical posture, pharyngeal airway dimensions and hyoid bone position. | Before treatment (T0) and after treatment (up to about 10-12 month; T1) for the study group. First measurement (T0) for the control group and after similar follow-up time (up to about 10-12 month; T1) as for the treatment group. |
