A 10-year evaluation of the quality of orthodontic treatment at the De
partment of Orthodontics, School of Dentistry in Malmo, University of
Lund, showed that in approximately 3 cases out of 4 (73%) successful r
esults were noted in the malocclusions under treatment. In approximate
ly half the cases the ideal treatment goal, normal occlusion, was achi
eved. The treatment was unsuccessful in 12% and in a large group of pa
tients (15%) the treatment was discontinued due to lack of motivation
or compliance. More accurate study and documentation of subjective nee
d of treatment (motivation, cooperation and social sufficiency) would
improve the quality of orthodontic care and make it more efficient. So
me sort of penalty due to distinct lack of patient cooperation might i
mprove orthodontic care. Root resorption occurred frequently during or
thodontic treatment with multiband fixed appliances, but the apical sh
ortening was small and without clinical significance.
