A survey was mailed to a stratified random sample of general dentists to determine the amount and nature of orthodontic treatment provided by general practitioners to their patients. The response to the survey was 75%, a rate considered excellent for this type of mailing. A large majority of the responding dentists (76.3%) provide orthodontic services to their patients, with 19.3% providing comprehensive orthodontic treatment. The percentage of time spent providing orthodontic services varied greatly among general dentists, with only a very few practitioners spending more than 50%. The number of patients under active treatment also varied widely, with only about 17% of those practitioners providing comprehensive treatment having more than 50 patients. A comparison of the three groups of practitioners showed that there was no relationship between the level of orthodontic involvement (none, limited, comprehensive) and the number of miles from orthodontic specialist or the pattern of referrals to orthodontists. Extrapolation of data from this study to the results of other investigations led to an estimate of the relative percentage of treatment provided by orthodontic specialists, pediatric dentists, and general practitioners. Almost two thirds of orthodontic patients are treated by orthodontic specialists, with pediatric dentists treating less than 4%. Slightly less than one third of all orthodontic patients appear to receive treatment from general practitioners.
一项调查被邮寄给普通牙医的分层随机样本，以确定全科医生为其患者提供的正畸治疗的数量和性质。该调查的回复率为75%，这一回复率对于此类邮寄调查来说堪称优秀。绝大多数回复的牙医（76.3%）为其患者提供正畸服务，其中19.3%提供全面的正畸治疗。普通牙医提供正畸服务所花费的时间比例差异很大，只有极少数从业者花费超过50%的时间。正在接受积极治疗的患者数量也差异很大，只有约17%提供全面治疗的从业者拥有超过50名患者。对三组从业者的比较表明，正畸参与程度（无、有限、全面）与距正畸专科医生的英里数或转诊至正畸医生的模式之间没有关系。将本研究的数据外推至其他调查结果，得出了正畸专科医生、儿童牙医和全科医生提供治疗的相对百分比估计。几乎三分之二的正畸患者由正畸专科医生治疗，儿童牙医治疗的患者不到4%。所有正畸患者中略少于三分之一的患者似乎接受全科医生的治疗。
