The aim of this study is to evaluate the treatment effects of conventional twin block appliance versus modified twin block appliance in the treatment of patients in growing stage having skeletal class II division 1 with mandibular deficiency.
The aim of the study is to investigate the effect of a pacifier (102 Medical Pacifier, Curaprox, Switzerland) on malocclusions like posterior crossbite, anterior open bite, larger overjet and tongue dysfunction in young children.
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.
It is intended to evaluate changes in arch dimensions and incisor inclination as well as changes in the WALA Ridge in no extraction patients treated with interactive self-ligating brackets (Empower®) and passive (Carriere SLX®) at the end of the phase of alignment and leveling. For this, study models and profile radiographs taken before the start of treatment and at the end of the alignment and leveling phase will be evaluated. The parameters to be measured are: intercanine distance, arch depth, upper and lower incisor inclination, and WALA ridge analysis
the study is searching if there is a relationship between the blood groups and RH and the skeletal malocclusion using the skeletal class I as a control group
The purpose of the study is to determine the prevalence of malocclusion among a group of Egyptian children with digit sucking aged 3 to 6 years.
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.
Patient safety is a great concern for the whole society. Since the investigators have a leadership in the medical field in Taiwan, the investigators should be courageous to face the reality from the patients seeking second opinions undergoing orthodontic treatment. Orthodontics just became a recognized specialty by the Department of Health in Taiwan in 2009. It is just a beginning to set up the training course criteria at the national level. It will be a good timing for us to look at the treatment quality when patients seeking second opinions at NTUH. Whether the unsatisfied results are from the patient's unrealistic expectation, patient's compliance issue, doctor's diagnosis, treatment planning or skills, or a simple communication problem, depend on a good systemic analysis from the records and questionnaire collected in a timely fashion. The investigators plan to ask patients who are undergoing full-mouth orthodontic treatment and seeking second opinion to join this study. The investigators will thoroughly explain to patients before they agree to take records and fill in questionnaire. Then the investigators use these records to perform root cause analysis. Our hypothesis is that the risk of adverse event (AE) is related to the training quality, communication skills, patient's understanding and compliance. From these results, the investigators shall be able to assess the risk of AE and make the education policy either at continued education level or special training courses towards a patient satisfied treatment.
Is their a association between the objective and subjective severity of a malocclusion, quality of life and self-esteem/personality (as modifier between objective/subjective severity and quality of life (cfr study Agou et al., 2008) ? A second goal is to compare motivation and expectations and the objective and subjective severity of the malocclusion on the other hand.
