EZ-BOND RETAINER
Clinical Information E-Z Bond is a .0195 multistrand wire retainer that has eliminated the guess work associated with bonded retainers and the good news is that it's compatible with your favorite composite. Multistrand wire retainers play a valuable role as follow-up retention to active orthodontic therapy and they have clear advantages over removable retainers. Until recently, however, there was no completely satisfactory or standardized method for placing and bonding multistrand wire retainers to the lingual surfaces of anterior teeth. E-Z Bond has solved this problem. The usual method of placement was to position the retainer wire on the etched and dried tooth surface. An arbitrary quantity of composite was then applied for the bond. Neither the position of the retainer, nor the quantity of bonding material was accurately controlled. Prolonged finishing procedures were often necessary to remove excess composite or to add extra material to deficient areas. Consequently, the chair-side time and appearance of the retainer were often unpredictable. Not with E-Z Bond. The E-Z Bond retainer provides precise control and consistent results. Now you can place the retainer where you want it with the right amount of composite material. The following information will show you how simply this is done. Taking the Impression Although the retainer will be bonded to the lingual surface of the anterior teeth, it is essential to include the incisal edges and a portion of the labial surfaces when taking the impression. After thoroughly cleaning the teeth, the undercut areas gingival to the
arch wire should be generously blocked out with soft wax (Fig. 1) to prevent distortion when the impression is withdrawn. An impression with alginate (Fig. 2) - or any other impression material - should be taken and poured in hard stone (Fig. 3). Clinical Procedures After removing the fixed appliances, prepare the lingual surfaces to be bonded in the normal manner. Your favorite bonding material should be mixed and injected into the template perforations using a composite syringe (Fig. 4). The standardized perforations are guides to be used to insure that over or under filling will be avoided. The template should then be placed on the teeth and gentle pressure applied until the material is set (Fig. 5). The template perforations permit any excess bonding material to harmlessly escape through the "escape channels" (Fig. 6) instead of being squeezed interdentally or gingivally (Fig. 7). It is very important that any overflow of the bonding material be removed with a large round burr before peeling back the plastic template (Fig. 8). To remove the template simply place one hand over the template covering all of the teeth except for one cuspid and one lateral. With the other hand, the template or transfer tray should be carefully peeled back tooth by tooth. Removal of the template will reveal a perfectly adapted lingual retainer attached to the teeth. You will see highly effective discrete studs of bonding material with uniform thickness and shape at the predetermined locations. You may easily round off any excess overflow of bonding material by using a round burr or any other suitable finishing stone (Fig. 9 & 10). A standardized procedure has been described to achieve precision multistrand wire retainer bonding. The flow of bonding material can be easily restricted to insure proper placement and to eliminate any periodontal complications. Standardization is achieved through the application of an indirect bonding technique that results in an accurate and elegant retainer requiring minimal chair time (Fig. 11 & 12). Since the E-Z Bond lingual retainer can be placed immediately after brackets are removed, a very effective and efficient invisible retainer results with optimal patient cooperation.
