[Status of orthodontics in Norway: 1990].

Norwegian orthodontics has a good international reputation. Most of the treatments are performed by specialists with a thorough postgraduate training. The treatment costs are partly covered by the National Health Service and partly by the patients themselves. The amount of repayment by the Health Service is dependent on the severity of the malocclusion. Most treatments are solved by fixed appliances often in combination with extraoral growth preventing or growth stimulating appliances. Adults demanding treatment of an earlier untreated malocclusion or together with periodontal and prosthetic treatment are increasing in most practices.
