[The system and realization of orthodontic treatment in Sweden].

The need for treatment is subdivided into 4 degrees of severity. Nearly 12% of the 7-16-year-old children and adolescents are in urgent need of treatment. The mean duration of treatment (per patient and year) is 4.2 hours. From this it is calculated that 1 orthodontist will be required for 24,000 residents or for 3,500 children and adolescents aged between 7 and 16 years. In Sweden each province (24) has at least 1 orthodontic clinic that is responsible for treatment and advice. The free treatment of patients being in urgent need for treatment is realized by an orthodontist in cases with a high degree of severity, and otherwise by a general dental practitioner who works indepently or takes the advice of an orthodontist.

The relationship between lower incisor inclination and various reference lines.

The relationship between the inclination of the lower incisors and different cranial reference lines has been studied in a group of 60 children including 35 males and 25 females between the ages of 7-12 years. Following a 3-4 year observation period, 30 of these children were reexamined to study the relationship between changes in the position of the lower incisors and various craniofacial variables brought about by growth. In analysing the results obtained, an attempt was made to distinguish between those relationships which were to a certain extent due to a topographical relationship between the variables involved and those relationships which were of a biological character. The results obtained from the first registration indicated a strong correlation between Ll-NB mm and Ll-ML degrees and Ll-NB degrees. In addition, the connection between lower incisor inclination and the basal bone relationship (ANB degrees) was found to be strongly significant. The angle ML/NL was found to be correlated only with the inclination of the lower incisors to the mandibular line. Regarding the growth changes occurring during the observation period, no significant correlation could be found between, on the one hand, changes in lower incisor orientation and, on the other hand, changes in the angle ML/NL. The absence of this relationship has been interpreted as being due to the influence of environmental factors in the form of tongue and lip function.

Periodontal health following fibrotomy of the supra-alveolar fibers.

A clinical follow-up study has been carried out in order to study the periodontal health of orthodontically derotated teeth where the supra-alveolar fibers have been severed by an incision through the bottom of the marginal pocket to the border of the alveolar bone in order to reduce the tendency towards a posttreatment relapse. The material consisted of 30 rotated teeth treated orthodontically in 27 patients between the ages of 9 and 22 years. Following an average retention period of 8.3 months, the supra-alveolar fibers were severed down to the alveolar bone border. The control material consisted of untreated, banded contralateral teeth in the same jaw. The patients were examined for plaque, gingival health and depth of the marginal pockets. No significant difference in periodontal health could be found on comparison between, on the one hand, teeth treated with fibrotomy and, on the other hand, untreated teeth.
