First of all, and before the start of preparing the tooth, you must know 4 basic things, the taper, finish line, follow the anatomy of the tooth and the undercut. If you know it, your preparation for the tooth will be very beautiful and excellent 🔥✨
We start with the finish Line, it must be conservative as much as possible. The types of Finish Line are Chamfer It is used for metal, which is 0.5 mm. The shoulder is used for ceramic, which is 1 mm, and it must be equigingival for aesthetics and prevent gingivitis
We are now moving to the Undercut to prevent it. You must hold the bur and Handpiece perpendicular over the tooth. If you finish, look with a single eye or from the top of the tooth, (Incisal Edge Interiorly or the occlusal surface in the posteriorly ) to see the finish line.
now the taper. It does not require any effort itself. All you have to do is hold the bur perpendicular to the tooth only, and the best result is when it is 6 degrees. The most important thing is to know that there is an inverse relationship between the taper and the Retention.
We now move to the anatomy. It does not require any effort either. Just follow the tooth, but be careful when the tooth is tilted, and remember that we make a reduction , not distraction
The last thing you need to focus on is any sharp edge or point, make it round, and do not forget to make the Bevel in the Functional cusp.
Finally, do not despair, with time you will learn.
