title: Contemporary trends in orthodontic practice: a national survey.
abstract: This study involved the development of a questionnaire to elicit information about current trends in orthodontic practice compared with trends of 5 years ago. The subjects addressed included the use of fixed appliances, functional appliances, extraction therapy, orthodontics and the temporomandibular joint, current diagnostic aids, and medicolegal implications of orthodontic treatment. The questionnaire was mailed to 1400 orthodontic specialists who were randomly selected from across the United States. There were 814 questionnaires returned, representing a 58.14% response rate. The major results of this survey are as follows: (1) The reported extraction rate has declined from a mean of 37.74% 5 years ago to 29.28% today. (2) TMJ concerns (or medicolegal implications thereof) have had a considerable impact in this decline, with 26.4% of orthodontists being influenced, to some extent, to extract fewer teeth because of this factor. (3) The use of functional appliances has remained somewhat static over the last 5 years, after a period of rapid growth in the 5 years previous to that. (4) The preadjusted edgewise appliance is by far the most popular fixed appliance in use today, being chosen by 72.6% of respondents. Analysis of the overall results lead to the following conclusions: (1) Fixed appliance therapy is the therapy of choice of the overwhelming majority of orthodontists. The use, benefits, and role in orthodontics of functional appliance therapy is considerably less defined. (2) Treatment modalities, notably on the use of extraction and its relationship to the health of the temporomandibular joint, should be determined by research, not by legal fears or unsubstantiated allegation.
