What I see in Kilgore teeth especially the 1.7 or 2.7 that the buccal wall tend to curve in a way which make prep that area challenging especially distobuccal
True. I've found that if I focus on creating 3 degrees of taper in the gingival 1/3 by using the side of the bur FIRST, then I follow with a secondary axial plane that follows the adjacent facial incline in the occlusal 1/3, the prep works well.
So this is a chamfer or shoulder? I can 't really differentiate between the two. Also, this preperation is suitable both for a full gold and a full ceramic crown, am I right? If we had more reduction on the lingual, then it would be suitable for a ceramic crown with metal base. Right?
The chamfer has a declination angle with the horizon of at least 45 degrees, and the prep in the video has a chamfer with a declination angle of about 60 degrees - the same as the 877 tip. Shoulders make 90 degree (or close to this) angles with the unprepared root surface and are typically deeper axially. Ceramic preps are much like gold except they are more rounded and use a "fillet" or rounded (internal) shoulder finish line. Tale a look at my other videos for more clarity on the ceramic and PFM preps.
0.5 at the finish line, gradually increasing to 1.5 mm at the occlusal. It's rarely done, but you could use a putty stent and measure the axial reduction halfway up from the finish line and it would be about 1.0 mm
@@StevensonDentalSolutions ok sir why i am waiting it eagerly because there are lots of factors play when you do the crown cutting in patient mouth like salivation, mouth opening, bulkiness of cheek, size of tongue, gag reflex. and these factors decide the crown cutting more than anything else.
@@StevensonDentalSolutions because its completely different to do crown cutting on model than in patient mouth. that's why i am very eager to see the percentage of idleness in mouth crown cutting.
Super sir.

Doc, when you said you are usually looking into a video monitor while prepping, does that go for patients as well or just the typho?

@@StevensonDentalSolutions thank you doctor! Very kind of you explaining this well!
Thank you Dr. What is the axial reduction for FGC?
0.5 at the finish line, gradually increasing to 1.5 mm at the occlusal. It's rarely done, but you could use a putty stent and measure the axial reduction halfway up from the finish line and it would be about 1.0 mm
great job doc wish if you post a video of temporary crown fabrication
Thank you - yes I have had that request many times - will try asap.
Can I get this kit of burs? And RGS instrument?
