Toboom- Posterior Teeth

1.SO-20 : ISo 806 314 289 524 008 (Reminder: The maximum speed of this model is 30,0000rpm/min) to open the proximal and distal surfaces, and the preparation amount is 1.0 mm each, so as not to hurt the adjacent teeth. (Protection of adjacent teeth with interproximal sheet before use)

2.BR-15: ISo 806 314 001 524 016 Preparation of labial and lingual edge and shoulder positioning 0.8 mm, the depth is shallow concave.

3.EX-52 : ISO 806 314 500 524 010 is used for positioning the posterior occlusal surface with a depth of 1.5-2.0 mm, and the depth is easy to control.

4. EX-55 : ISO 806 314 552 524 030, the transverse/vertical incision of the posterior teeth is 1.2-1.5 mm deep, and the depth is easy to control.

5.TR-D10: ISo 806 314 196 524 020 Grind the occlusal surface positioning depth, and prepare the original occlusal surface shape from the occlusal surface.

6.TR-33 : ISO 806 314 198 524 016 is the main bur, grinding and positioning the deep remaining tooth tissue, preparing each axial surface, shoulder and coronal edge.

7.SF-D41F : ISO ISO 806 314 111 514 012 is used for the finishing of shoulder and shaft surface.

8.TR-O8F : ISO 806 314 537 514 021 is used for shoulder finishing, removing edges and non-edges.

9. TR-D36F : ISO 806 314 198 514 024 is used for the finishing of each axial surface, occlusal surface, coronal edge and shoulder of the tooth. The angle of the bur is too large. Pay attention to the direction.

10.SH 3414 : ISO 658 204 304 514 100 using a slow-speed elbow to throw the occlusal surface and the convergence angle of each axial surface. (Pay attention to the use of water jet polishing under the vital pulp to prevent heat generation from stimulating the tooth nerve)
