Caution: Long video - time
Caution: Long video - time stamps provided below the description to reach every step.
The video shows the demonstration of tooth preparation, for mandibular first molar (FDI tooth #36) in a typodont, to receive a full veneer (full coverage/complete coverage) crown. The video is edited very minimally to show almost all stages of the preparation, along with graphical illustrations and simultaneous commentary in English. The video is suitable for beginners in dentistry, dental students, and as a reference to other creators. Editing is done with #kinemaster
The video is dedicated to all the dental students in the preclinic stage. Hope it'll be of great assistance to them.
