Multi-disciplinary Diagnosis and Treatment Process and Evaluation System for Children With Sleep...

Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) and Malocclusion

The aim of this study is to compare the efficacy and safety of drug therapy, tonsillar adenoidectomy only, orthodontic treatment only and tonsillar adenoidectomy plus orthodontic treatment in children with obstructive sleep apnea hypopnea syndrome (OSAHS) and malocclusion. In this study, we hope to improve children's OSAH in function, three-dimensional shape and subjective and objective symptoms of sleep breathing through tonsillar adenoidectomy plus orthodontic treatment.

Study to Compare Two Functional Appliances for Class II Malocclusions

MalocclusionAngle Class II

A randomised controlled clinical trial to compare the effectiveness of two functional appliances in the correction of a Class II malocclusion. (Class II malocclusions are where upper front teeth bite significantly further forward in relation to lower front teeth). Null hypothesis: There is no significant difference between the Button & bead and Twin-block appliances with regard to time taken to reduce the overjet

Effect of Bone-anchored Protraction on Maxillary Growth in the Young Child

Maxillary HypoplasiaMalocclusion1 more

Class III malocclusions may originate in a retrognathic maxilla, a prognathic mandible or both. Young patients with class III malocclusion and maxillary hypoplasia are conventionally treated with a protraction facemask in order to stimulate forward growth of the upper jaw. This treatment option is often inducing unwanted side effects including mesial migration of the teeth in the upper jaw and clockwise rotation of the mandible. Because skeletal effects are often difficult to achieve with this approach, more pronounced class III malocclusions cannot be addressed by face mask therapy. These children cannot be treated during childhood and end up in major orthognathic surgery at full-grown age. To be able to treat also the more pronounced class III malocclusion and to minimize dentoalveolar compensations new treatment methods were developed which uses skeletal anchorage.

Comparison of Efficacy of Three Orthodontic Appliances

MalocclusionAngle Class II

To investigate each treatment modality in its "optimal" environment to avoid operator experience bias. Therefore we propose to operate out of three "specialist centres" with specific units providing one modality alone Which of the three orthodontic appliances does achieve best clinical progress, produce least discomfort to the patient, minimize the time taken for completion of treatment and maximize compliance.

Analysis of the Dentoskeletal Effects of the Expander With Differential Opening

Maxillary ConstrictionUnilateral Posterior Crossbite2 more

This study evaluates the dentoskeletal effects of the expander with differential opening in orthodontic patients in the mixed dentition. Half of participants will undergo rapid maxillary expansion (RME) using the expander with differential opening, while the other half will undergo RME using the conventional Hyrax expander.
