Thanks Dr Michael for the valuable information about the reverse preparation technique. I have been using this technique for a couple of years and I am able to prepare clear margins. With the double cord retraction, impressions are predictable but a little cumbersome. I just wanted to know the adequate time required to prepare a tooth from start to finish. Anil from India.
Thank you for a great video Dr. Michael but can I ask a off the topic question about how to use a articulating paper on opposing crown restorations. Let's say I've made 2 crowns for the patients number 26 and 36, patient does not miss a tooth and the crowns are high. So because they are opposing teeth how can I know which crown I should reduce to achieve occlusal adjustment? The both crown will be painted because of the hight.
I work at a dental clinic as a hygienist assistant, so I thought I would take a look at what the big dogs are doing. Big mistake cause I don’t understand a single thing he’s saying and I feel very stupid. Besides that Thanks for the interesting video
Dear Chris, thank you for watching this video and for leaving this feedback. You can visit here for more in-depth explanation of his tooth preparation techniques and reasoning behind it. glidewell.dental/CrownBridgePrepCE
Round off the retentive elements of the tooth preparation because our mills can't properly mill angular detail and only have rounded tips? Tell me that didn't just come out of your mouth. New grads are coming out of school with fewer requirements than ever and you guys are teaching them the marshmallow prep due to inadequate bur selection? Say it isn't so.
No and no. Carbides have no business cutting a crown. I hate this method. You cant see blushing as you prep margins or depth. Yeah zirc needs its clearance. But not every tooth is cut out for zirc, and sometimes you wont know that until you prep and are actively following the changes in shade and translucency of the tooth. Also zirc is not the most conservative, and we all know it
