متن کاملThree-dimensional Assessment of the Pharyngeal Airway and Maxillary Sinus Volumes in Individuals with Non-syndromic Cleft Lip and Palate
Introduction: Children with cleft lip and palate (CLP) are known to have airway problems. Introduction of ConeBeam CT (CBCT) and imaging software has facilitated generation of 3D images for assessing the volume of maxillary sinuses and pharyngeal airway. Consequently, the present study aimed at evaluating and comparing the maxillary sinus and pharyngeal airway volume of patients with cleft lip ...
متن کاملOptimal force for maxillary protraction facemask therapy in the early treatment of class III malocclusion.
BACKGROUND The facemask is used to treat early class III malocclusion, in combination with expansion therapy. There is a great deal of controversy in literature regarding the effectiveness of protraction facemask treatment as studies report results anywhere from considerable changes to lack of any maxillary improvement. This controversy may be due to the fact that the process of placing the ort...
متن کاملTreatment and post-treatment effects of facemask therapy on the sagittal pharyngeal dimensions in Class III subjects.
The purpose of this cephalometric study was to analyse the treatment and post-treatment craniofacial effects of a facemask (FM) combined with a bite block (BB) with specific regard to the sagittal pharyngeal dimensions in subjects with a Class III malocclusion when compared with an untreated Class III control group. The FM/BB group (22 subjects, 12 females and 10 males) had a mean age pre-treat...
