Standard clinical procedures are followed as usual at each clinic where standard diagnostic and follow up materials are taken before treatment, after treatment and follow ups after 5 and 10 years. The project will not introduce or test new treatment modalities, additional procedures or behavioural regulation in relation to normal clinical practice or new medical devices. The standard diagnostic and follow up materials in each clinic include examination of the dentition, occlusion, craniofacial morphology, and orofacial function. The analyses are based on the following standardized registration methods which are carried out on all the patients. Information from the patient record is included.\n\nThe patient related outcome measurements will be assessed by five different questionnaires.
