Under the Health Act, orthodontic services are provided by all health boards to persons, including persons who are eligible for GMS services, who are assessed as being in need of such treatment. The service is provided under guidelines issued by my Department which sets out the priority to be given to certain orthodontic conditions. In implementing their statutory remit, health boards apply the services to persons on the basis of the assessments which are initiated through the national school dental programmes and having regard to the time at which the person was assessed. In the light of the needs of the orthodontic services a development plan for the health board orthodontic services has been prepared for implementation over the period of the Programme for Government.
