Ever since its inception by Nielsen et al1 , exposure and bonding of unerupted teeth has been routinely carried out in most oral and maxillofacial departments after joint treatment has been planned with hospital or practice-based orthodontists. Becker2 showed that bonding at the time of exposure was superior to bonding at any other time, but this can be quite challenging particularly when the angulation required for optimal placement is awkward. This is often exacerbated because of the inadequate surface area on the bracket on to which an instrument may be applied. Occasionally, the bracket may be dropped, further increasing the surgeon’s frustration. We report a simple technique to improve holding and gripping the bracket to facilitate its intraoperative placement on the tooth, as well as reducing the incidence of lost brackets. A ball of light-cured composite [3M Unitek; TransbondTM XT] about 2–3 mm in diameter is rolled and flattened into a sphere before being placed and cured on the hooked surface of the bracket (Fig. 1). The procedure takes seconds and a batch of modified brackets can be produced in one sitting for later use. Naturally, the additional composite increases the surface area for gripping; it holds and positions the bracket on the tooth with ease using mosquito forceps, college forceps, or a curved haemostat.

We have also found that vision or access is not compromised in any way. This modification has been used successfully in a number of cases in our department. There has been no problem with increased bulk in terms of patients’ discomfort, wound dehiscence, or tissue reaction.
