The SHOFU All Ceramic Preparation Kit is a specialized set of diamond burs designed for efficient and precise tooth preparation for full-ceramic, inlay/onlay, and veneer restorations. The kit includes 17 burs, each serving a specific purpose in clinical applications:
896, 897: Specially designed burs for the preparation of depth orientation grooves.
896: 0.5mm depth for all ceramic laminate veneer preparation.
897: 1.0mm depth for anterior tooth, all ceramic crown preparation.
0836, 836V: Designed for the preparation of the anterior tooth, buccal surface of upper and lower premolar, or cervical area on the lingual surface. Use 1/2 - 2/3 of the diameter, head length 9mm, diameter 1.3mm with a tapered angle of 4°.
0839, 839V: Designed for the preparation of buccal and lingual surfaces of upper and lower molar teeth. For cervical area, use 2/3 of the diameter, head length 9mm, diameter 1.5mm with a tapered angle of 20°.
0893, 893V: Designed for cutting upper/lower anterior tooth on the lingual surface (to maintain occlusal space) and lower premolar on the occlusal area. Head length 4.9mm.
0899, 899V: Designed to reduce an upper premolar and the occlusal surface of an upper/lower molar to maintain the occlusal space. Tapered 20° angle.
808V: Use this diamond bur after the preparation is finished to eliminate free enamel in the cervical area. Use a lower speed to avoid chipping the enamel. Head length 8mm.
0833, 833V: Designed to slice cut at the interproximal surface or box preparation at the interproximal surface of class II inlay restoration. Use ½ the diameter, except when preparing the lingual cervical area of a lower anterior tooth use 2/3 the diameter. Head length 9mm, diameter 1.1mm (at the top of working part) with tapered 4° angle.
0825, 825V, 0826, 826V: Designed to prepare the occlusal box-form of an upper/lower premolar and molar.
0826, 826V: Used for occlusal box-form for upper and lower molar. Head length 3.5mm, diameter 1.5mm and 2mm with tapered 20° angle.
Features :
A careful selection of a total of 17 burs for speedy, simple and accurate all-ceramic preparation work
2 specially designed depth cutting burs to achieve precise depth orientation grooves for accurate labial reduction during crown and veneer preparation
Sequenced grades of 2 grits
Regular:(no marking on the shank) Super-Fine:(yellow band on the shank)
All 17 burs are placed in a hygienically organized bur stand for convenient storage and easy replacement.
1 x 17pcs of Diamond Points FG in 2 different grits (Regular & Superfine)
Direction To Use :
For Anterior Preparation
Slice cut the interproximal area of the anterior tooth. Use the long axis of the bur. After slice cut, retract tissue with retraction cord.
Reduction of incisal edge. Reduce the incisal edge 1.5 – 2.0 mm. Angle the diamond toward the lingual to stay parallel with the incisal line.
Prepare the labial surface. Cut lateral guide grooves 1.0 mm deep on the labial surface to guide the depth of the cut
Reduce the labial surface to the depth the lateral guide grooves
Prepare the labial and lingual cervical area. Cut from the lowest point of the cervical scallop mesially and distally on the labial and lingual surfaces. Make sure to reduce enough in the center of the labial and lingual surfaces. Reduce enough in the center of the labial surface and not too much in the interproximal subgingival cervical areas
Prepare lingual space. Do not cut too much of the axial lingual wall
Free enamel at cervical area
Prepare the shoulder margin. Smooth and finish the enamel at the cervical area
Smooth and finish the shoulder prep by using the outside 1/3 of the bur cutting edge that is away from the long axis of the prep. Move the bur in the direction of the rotation
Place the bur vertically on the shoulder margin surface, not parallel to the long axis of the tooth preparation
Completed preparation. Imagine the final shape while cutting the preparation
For Premolar Preparation
Preparation of lower premolar (1st bicaspid).
Reduce the four surfaces of the premolar. A slight undercut will occur while following the lingual inclination of the premolar. The bur, when placed correctly against the occlusal plane, will tip toward the buccal surface.
Reduce the apex of the buccal cusp following the inclined plane angles
Utilizing the premolar anatomy. The occlusal surface is prepared similar to an anterior preparation
To make broad mesial and distal pits in the occlusal surface, reduce toward each interproximal direction
For Molar Preparation
Preparation of upper molar
Reduce occlusal surface to create occlusal space. Use shape of the bur top to cut the central groove and to shape the side areas for the pits of the crown
Use the nipple part of the bur top to smooth and finish the overall edge of the occlusal and axial angle
