Abstract

A Preprimed bracket refers to a bracket whose base has been primed with an adhesive component. The bracket base is covered with a PMMA powder primer. When bonding, the base is dipped in 4-META/MMA-TBB resin monomer for two or three secondsand merely pressed into place on the etched tooth surface. A setting time of eight minutes is allowed before placement of maxillomandibular ligation or traction in the usual manner. Bracket removal may be accomplished by using a bracket removing plier. We tried to bond 212 brackets on tooth surfaces in 17 cases of fractured jaws, orthognathic surgery, etc. It was observed that during about 7 weeks of fixation, the frequency of breakage bonding was only 0.9%. Our preprimed bracket technique showed a lower frequency of breakage of bonding than did the brush-on technique. The technique utilizing our new direct bonding bracket offers many advantage: a) it is a relatively easy and painless procedure, b) it does not injure teeth or periodontal tissue, and c) in comparison with wire ligation in fixation of loosened and displaced teeth, the result of the new method seems to be much better.
