The Hemodynamic Changes of Cervical Spondylosis(CSA) of Vertebral Artery Type Patients after the Front-traction;

Study of changes of hard tissues following application of combined rapid maxillary expansion (RME) and maxillary protraction therapy in skeletal class Ⅲ patients of different ages;

Clinical analysis of treatment effects of sketetal permature classⅢ macclusion with rapid expansions and maxillary protraction;

Clinical study of changes in dentofacial morphology in skeletal class Ⅲ patients after pubertal growth by maxillary protraction;

Destoalveoler changers in skeletal Class III patients after maxillary protraction in the mixed dentition.;

Clinical Research on the Effect of Protraction Headgear Combined with Rapid Palatal Expansion in Correction of Skeletal Class Ⅲ Malocclusion;

Changes of jaw structure after maxillary protraction in patients with class Ⅲ skelecal malocclusion referring unilateral cleft lip and palate;

Objective This study was to investigate the TMJ of the modified fixed reverse TBA combine maxillary protraction on treatment of early Angle Ⅲ skeletal anterior crossbite.

The purpose of the study is to analyse the biomechanical effects of the maxillary protraction from different directions by the three-dimensional finite element model of a young people s craniofacial skeleton with maxilla retrusion and skeletal class Ⅲdiscrepancy.

Objective To evaluate curative effects of maxillary protraction on Angle Ⅲ anterior crossbite treatment.
