Designed for use in the straight- or laboratory-style handpieces, these burs can be used for a wide variety of tasks in a dental laboratory. Straight handpiece burs are available in a variety of formats and head shapes, so it is important to find the correct bur for the material you will be trimming. Some burs are designed for trimming precious alloys, while other are for shaping dental models or ceramic restorations. If you work with a straight handpiece, be sure to keep an array of straight handpiece burs on hand to handle whatever task the next case requires.
