A number of adhesive systems for the direct bonding of orthodontic attachments to the tooth surface have been reported during the last five years. The purpose of this investigation is to evalua te clinically a new bonding system which appears to have apparent advantages over previous techniques. Seven months trial of 552 brackets in the mouths of 59 patients is not enough time to completely evaluate the system. However, it appears to have greater stability and durability in the actual treatment of malocclusions than previous techniques. These brackets can withstand comprehensj_ve treatment procedures including the use of extraoral forces and torquing moments. Additionally, these brackets can be placed efficiently and quickly. There are many advantages to such a handless technique to both the patient and the orthodontist. Patient discomfort is minimized by the elimination of "tooth separation" often necessary for band adaptation and -cementation. Stresses on the orthodontist are reduced due to the elimination of banding appointments. Decalcifications, due to disintegration of the cement under the bands, are decreased since there is no partial cement washout without complete dislodgement of the bracket. Gingival irritations are drastically reduced since there are no bands to seat subgingivally. The patient's oral hygiene appears to be improved with the elimination of the bands and aesthetics is greatly improved.
