Amazing demonstration 💯

Please share the bur number like you said at the 1.49 part of the video for example 014 green champher ,

really helpfull

Thank you so much Can you please explain how you determine the line of draw? Do you keep bur facing the mesial proximal wall straight and the distal proximal wall a little bit tilted towards the mesially as the premolar is mesially tilted  for maintaining line of draw? Also, for occlusal, do we don't have to preserve the cuspal anatomy, right, just the groove right so I can make them straight ? and also for buccal and lingual we have to do both side two planar prep and bevel on functional palatal cusp is it also 1mm ? Thank you

What speed are you using? How many rpms?
