[The course and results of the orthodontic treatment of 44 consecutively treated Class-II cases].

In this study treatment progress and treatment results of a consecutively treated group of 44 patients displaying a Class II malocclusion were evaluated in their relationship to the treatment goal. 41% of the patients had come to see the orthodontist on the advice of their family dentist but without any subjective problems as regards their tooth position. In 43% of the patients the treatment could not be finished in accordance with the treatment plan. In approximately 2/3 of these cases the reasons for the compromised results were due to patient cooperation problems. In the other 1/3 various types of treatment problems were encountered with loss of anchorage being the most typical. Over the entire treatment period patient cooperation was good in only approximately 50% of the cases. Oral hygiene was good in 27% of the patients at the first consultation appointment, but during the course of treatment this percentage increased to 64%. 85% of the patients expressed satisfaction with treatment results, but 34% of the patients did find the treatment to have been a burden. Enamel decalcifications were noticed in eleven patients. In another eleven patients root resorption of more than 2 mm of at least one upper incisor was noted.
