A precise tooth preparation technique assisted with quantitive bur and microscope / 华西口腔医学杂志

Although traditional tooth preparation techniques (e.g., depth-groove-guided and index-guided techniques) are designed to improve preparation precision, the results are unsatisfactory because of the lack of proper estimating tools. This study proposed a novel technique, in which relevant details for preparation of drilling holes are provided and corresponding depth is estimated using a quantitive bur under a microscope. This technique offers a viable option for precise tooth preparation.
