Comprehensive Bur Kit – 14 Burs

Description

This is a set of specifically shaped 14 gold series burs used for all types of crown and bridge preparations.

1. MS 1.0 This is a Modified Shoulder bur with a tip diameter of 1.0 mm. The classic shoulder bur creates a sharp internal line angle (butt) at the preparation margin. This area is prone to stress concentrations, possibly leading to abutment fracture at the neck region. The MS bur has been designed as a flat tip bur, but with rounded edges that produce a smooth junction between the finish line and the axial walls. Such a modification helps reduce stress concentrations at this vulnerable part of the preparation. This bur is to be used by sinking the tip to its full depth, thereby leaving a 1.0 mm groove in the tooth. Use: For preparing buccal/ labial margin for a PFM prosthesis.

2. DC 1.0 This is a Deep Chamfer bur with a tip diameter of 1.0 mm. This bur is to be used only half its depth in order to avoid formation of a lip of enamel at the margin. Thus when used correctly, the 1.0 bur leaves a 0.5 mm groove in the tooth. Uses: For preparing the lingual/palatal margin when planning a PFM prosthesis with a lingual/ palatal metal collar. It is also used for preparing all the margins (360°) when planning a monolithic zirconia or a monolithic metal prosthesis and for a PLV preparation.

3. MS 1.3F This is a Modified Shoulder Finishing bur with a tip diameter of 1.3 mm. This bur is used by sinking the tip slightly short of its full depth, thereby developing a margin that is 1-1.2 mm in width. Use: For finishing buccal/ labial and proximal margins when preparing the tooth for a PFM prosthesis.

4. DC 1.2F This is a Deep Chamfer Finishing bur with a tip diameter of 1.2 mm. As this is a deep chamfer design, it is to be used only half its depth to avoid formation of a lip of enamel at the margin. Thus when used correctly, this bur leaves a 0.5-0.6 mm deep chamfer margin. Uses: For finishing the lingual/ palatal margin when preparing the tooth for a PFM prosthesis with a metal collar. It is also used for finishing all the prepared margins (360°) when planning a monolithic zirconia or a monolithic metal prosthesis. In addition, it is also used to finish the proximal and palatal/ lingual margins for a PFZ or a LiDiSi prosthesis, especially for anterior teeth.

5. DC 1.4 This is a Deep Chamfer bur with a tip diameter of 1.4 mm. This bur is also to be used only half its depth. Thus when used correctly, it leaves a 0.5-0.7 mm deep chamfer margin. Use: For preparing all the margins (360°) when planning for a PFZ or a LiDiSi prosthesis.

6. DC 1.8F This is a Deep Chamfer Finishing bur with a tip diameter of 1.8 mm. This bur is also to be used only half its depth. Thus when used correctly, it leaves a 0.8-0.9 mm deep chamfer margin. Use: For finishing the buccal/labial aspect when preparing tooth for a PFZ or a LiDiSi prosthesis.

7. MI 0.8 This is a Modified Interdental bur with a tip diameter of 0.8 mm. The Modified interdental bur is safe ended (no diamonds at the tip). This prevents the bur from slipping gingivally as one moves from the labial/ buccal towards the lingual/ palatal surface. This prevents gouging of the margin and trauma to the gingival col, a common occurrence during interproximal reduction. When using this bur, it is important to start above the interdental papilla on the buccal/ labial aspect and then running it across the inter-proximal tooth structure. Use: For opening interproximal contacts when preparing the tooth for a PFM prosthesis, especially for molars.

8. MI 0.5 This is a Modified Interdental bur with a tip diameter of 0.5 mm. This bur is also safe ended and is to be used in the same manner as that described for the MI 0.8 bur. Use: For opening interproximal contacts when preparing the tooth for a PFZ, a LiDiSi, a monolithic metal or a monolithic zirconia prosthesis, especially for anterior and premolar teeth.

9. OR 1.6 This is an occlusal reduction bur with a diameter of 1.6 mm through its entire length (straight bur). It is used by sinking the bur to its full depth, ensuring the bur follows the preexisting cuspal incline; thereby allowing anatomic reduction of the occlusal aspect. Use: For occlusal reduction of the functional cusps when preparing a tooth for a PFM prosthesis.

10. OR 1.2 This is an occlusal reduction bur with a diameter of 1.2 mm through its entire length (straight bur). Uses: For occlusal reduction of non-functional cusps when preparing a tooth for a PFM prosthesis. Also used for reducing the entire occlusal table (both, functional and nonfunctional cusps) when preparing a tooth to receive a PFZ, a LiDiSi, a monolithic metal or a monolithic zirconia prosthesis.

11. CR 2.3 This is a Cingulum Reduction bur with a diameter of 2.3 mm at its widest circumference. It is used by positioning the bur such that its widest portion sits into the deepest concavity on the palatal/ lingual aspect of the tooth being prepared. Use: For reduction of the lingual fossa when preparing the tooth for a PFZ, a LiDiSi or a PFM facing prosthesis, especially maxillary lateral incisors and mandibular anteriors.

12. CR 2.8 This is a Cingulum Reduction bur with a diameter of 2.8 mm at its widest circumference. This bur is used following the same protocol as that mentioned for the CR 2.3 bur. Use: For reduction of the lingual fossa when preparing for a PFM prosthesis, especially maxillary central incisors and maxillary canines.

13. EC 1.4F This is an End Cutting Finishing bur with a tip diameter of 1.4 mm. This bur has diamonds incorporated only at its tip and has a non-cutting shank. The non-cutting shank of the bur allows for it to be used on proximal surfaces of the prepared tooth, without the fear of inadvertent damage to the adjacent teeth. This bur is to be used with pull strokes only, as a push stroke carries the risk of ploughing/ digging the bur into the prepared margin. Use: For removing irregular/unsupported tooth structure around the prepared margins.

14. IR 2.0 This is a self-limiting Incisal Reduction bur with a working length of 2.0 mm and a tip diameter of 1.0 mm This bur is used by holding its shank flush with the incisal edge of the tooth and then moving it straight through from the labial into the palatal/ lingual aspect (in one sweeping motion). When used correctly, it leaves a groove that is 2.0 mm deep and 1.0 mm wide. Use: For preparing depth grooves, when reducing the incisal edge for all types of prosthetic materials.
