简要总结
The study will monitor changes induced by orthodontic treatment and in the retention period, two years after the end of orthodontic treatment. The alignment of teeth, hygiene and gingiva will be assessed. Efficiency of two types of fixed appliances in active phase will be compared - esthetic and metal. Efficiency of two types of retention appliances in retention phase will be compared - fixed and removable.
The benefits of orthodontic treatment to be studied are aesthetic concerns, dental self-confidence, self-esteem, social contacts, psychological influences, and chewing limitation. The stability of personality traits, body image and perfectionism will also be analyzed, as well as the extent to which these dimensions modify the reporting of psychosocial effects of malocclusion treatment.
详细描述
The aim is to analyze:
- the extent to which the type of device (metal / aesthetic) affects changes in quality of life (QoL)
- whether the change in QoL is influenced by personality traits during therapy
- long-term change in QoL and personality traits (before therapy, during, at the end and in retention for 2 years)
- whether long-term QoL change is influenced by personality traits
- dependence of relapse (incidence and intensity) on the type of retention appliance
- change in QoL and personality trait depending on relapse
- whether the change in QoL due to relapse is influenced by personality traits
