Interproximal reduction: a restorative adjunct to orthodontic procedures: Part I.
A technique of interproximal reduction for posterior teeth using an air rotor has been devised and demonstrated. This involves the customising of commercially available tungsten carbide burs and using them to reduce enamel on the interproximal surfaces of posterior teeth. The surface of the tooth adjusted in this way is smoother than the surface obtained by adjusting with a finishing diamond. In addition, a marginal ridge form can be developed which allows for easy finishing with fine abrasive polishing discs, so as to leave a surface which approximates that of the original tooth surface for marginal ridge form and smoothness.
