Abstract
A method of finishing resin-based dental restorations by contouring and smoothing the surface of the dental restoration in a single step, using steel burs operating at low speed, high-torque.
Claims6
A method of finishing resin-based dental restorations, comprising the steps of:
- preparing a dental restoration using a resin-based material;
- fine contouring the restoration and creating a smooth transition between the resin-based material and tooth in a single step using a bur having between 8 to 30 flutes and operating at less than about 30,000 rpm and having sufficient torque to maintain a constant speed of about 12,000 to 30,000 rpm when firm, continuous pressure is applied to the resin-based material.
