Thank you so much for your videos! Really helps.. Can you also please tell me that what would be the difference between amalgam and composite prep? Their angle , walls etc! Thank you

@StevensonDentalSolutions 4 жыл бұрын

Comspoite would have slightly flared exit angles, less clearance (0.2-0.3) rounded internal line angles, and shallower pulpal - just barely into dentin, 1.25 mm

Yes, depending on the school..for DO's most cross the oblique ridge as the retention is easier to achieve.

Thank you doctor , but I don't understand completely the part the preparation of box , can you type the steps in comment for me ??

@StevensonDentalSolutions Жыл бұрын

1. Use the 245 to drop the box to the full length of the flutes. 2. increase the gingival until the contact is broken 3. Increase the buccal and lingual until they are broken - use the hatchet to assist in removing undermined enamel. 4. Deepen the axial wall enough to extend about 0.5 mm into dentin (1.25-1.5 mm total from the outer margin) 5. Sharpen internal line angles with a 169L and enamel hatchet. 6. Smooth the transition from the box to the occlusal ("S" curve) 7. Refine the entire pulpal and vertical walls with an RGS 330. 8. Bevel the axial pulpal line angle to 0.3-0.5 mm with a gingival margin trimmer 9. Place a slight bevel on the gingival wall to remove unsupported enamel, also using a GMT.

After filling teeth again starts to lightly pain , what's the solution?

@StevensonDentalSolutions 4 жыл бұрын

Usually a failure of the bond - likely requires replacement and strict adherence to protocols

Why is it that only the wall of the functional cusp has an acute line angle and the non-functional 90 degrees instead of both having acute for retention form?

@StevensonDentalSolutions 4 жыл бұрын

1. Avoids undermining/weakening the non-functional cusp wall, 2. preserves facial esthetics for maxillary preps, 3. follows natural contours, and 4. allows for a uniform extension from occlusal to gingival. It's an advanced Operative Dentistry principal that was developed by Sturdevant, Markley and others in the 1960's but not known or adopted by several schools that are perhaps less focused on advanced operative dentistry. Interestingly, in the US, several schools were using 557 burs to prep class II amalgams until fairly recently - wow, now that's late adoption of evidenced based principals!

@ryanlam1635 4 жыл бұрын

@@StevensonDentalSolutions Wow, that is really fascinating! Well, I guess we're all lucky to have you to instruct us in these principles! One more thing, I sometimes struggle with correctly gauging the correct height/contour of the mesial/distal marginal ridge (sometimes it's too shallow or too excessive). Do you have any tips on ensuring correct anatomical replication? Would it be helpful to compare the marginal ridge height of the adjacent tooth?

@StevensonDentalSolutions 4 жыл бұрын

@@ryanlam1635 It is helpful and it's also helpful to make a note of the marginal ridge form level - ask yourself: is this higher, level of lower than the adjacent tooth and will the remaining cusp ridges (after pre) help me to develop the ideal form ...

@ryanlam1635 4 жыл бұрын

@@StevensonDentalSolutions so the marginal ridge of the prepped tooth should be equal in height to the marginal ridge of the adjacent tooth ?

Can I say safely that using only 330 & 245 are greatly enough in all posterior cases and ignoring the inverted & fissure burs ? Thank you in advance Doctor ✨

@StevensonDentalSolutions 4 жыл бұрын

You can - however, the 330 RGS which is a new bur introduced to dentistry in 2018 accomplishes superior finishing while maintaining the convergence and conservative prep design. It's best to avoid straight fissure burs while completing an amalgam prep (55, 56 ,etc) as they are not designed to maintain convergency. The use of inverted cones (34, 34, etc) is also not recommended as these are too sharp and are not long enough to smooth the vertical walls while smoothing the pulpal or gingival walls. Check out the 330 RGS by Brasseler, or on eBay or on stevensondentalsolutions.com - it's an amazing bur.
