The primary use of round burs is in the removal of carious dentin during cavity preparation. They are particularly effective in accessing deep carious lesions and creating rounded internal angles in restorations, which help in stress distribution. Additionally, round burs are used to create retention features in cavity preparations, enhancing the stability of restorative materials. Dentists often rely on these burs for their ability to remove decay quickly while minimizing damage to healthy tooth structure.
Pear-Shaped Burs: Design and Functionality
● Unique Shape and Advantages
Pear-shaped burs are characterized by their tapered, bulbous design, which resembles a pear. This shape allows for the efficient creation of undercuts and the preparation of cavity walls with a slight occlusal convergence. The design of pear-shaped burs facilitates controlled removal of tooth structure while allowing for precision placement of restorative materials.
● Applications in Tooth Trimming and Fillings
In restorative dentistry, pear-shaped burs are invaluable for creating undercuts that secure filling materials in place. Their design also makes them ideal for trimming and finishing composite restorations, ensuring a smooth transition between the restoration and natural tooth surface. Dentists prefer pear-shaped burs when precision and control are paramount, such as in the preparation of occlusal surfaces and proximal box forms.
Cylindrical Burs: Precision in Cutting
● Design Features of Cylindrical Burs
Cylindrical burs, with their straight sides and flat ends, are designed for precise cutting and shaping of dental materials. These burs are often available in a variety of diameters and lengths, allowing them to be used in a range of clinical scenarios.
