NOCTI Dental Assisting - Exam Topics Sample Questions

For which of the following procedures would you choose a flame diamond bur?

Correct Answer:
when a beveled subgingival margin is needed for a crown preparation.


the flame-shaped diamond bur is a specialized dental tool designed for specific types of crown preparations, particularly when a beveled subgingival margin is required. this type of margin is often needed to ensure a precise and aesthetically pleasing interface between the crown and the gum tissue, which is critical for the overall success and appearance of the dental crown.

the design of a flame diamond bur is ideally suited for creating beveled margins due to its tapered and pointed tip. this shape allows the dentist to access the subgingival area of the tooth with greater precision, facilitating a smooth and accurate cut that follows the contours of the gum line. the beveled edge created by this bur provides an optimal angle for the crown to sit securely and seamlessly on the tooth, enhancing both the function and the appearance of the final restoration.

in addition to its specific shape, the diamond coating on the flame bur provides several advantages. diamond is one of the hardest materials available, allowing the bur to cut through enamel and dentin efficiently. the abrasive surface of the diamond particles ensures a smooth and continuous removal of tooth structure, which is essential for achieving the desired contour and depth of the crown preparation.

moreover, flame diamond burs come in various sizes and grits, enabling customization according to the specific needs of the tooth and the type of crown being prepared. the selection of the appropriate size and grit is crucial, as it affects the precision of the margin preparation and the overall ease of the procedure. coarser grits are typically used for rapid reduction of tooth structure, while finer grits are used for finishing and polishing the margins, ensuring that they are smooth and free from irregularities.

ultimately, choosing the right bur, such as the flame diamond bur for creating beveled subgingival margins, plays a pivotal role in the preparation of a tooth for a crown. this ensures not only the longevity and success of the crown but also the satisfaction of the patient with the aesthetic outcome.
