Thanks so much Dr Stevenson for this amazing demo of Class 2 amalgam prep, which is a nightmare for many dental students including me. I have one question though, I have been preparing MOD prep and noticed that distobuccal cusp is getting very small after the final preparation coz of extension of proximal box buccally to get enough clearence. I was just wondering is this acceptable or is there any method for distobuccal cusp preservation in order to prevent over reduction of that particular cusp? I hope you got my query, thanks for reading and I will be waiting for your response. Thanks and Regards.

Yes, dropping the box means to remove the proximal tooth structure from the occlusal aspect, moving gingivally, hence "dropping" the box. Actually a better way of saying this would be to create the proximal box...

Hi Doc, your content is saving my life in dental school. Thank you for putting out amazing content. A quick question. I recently started practicing for Class II Amalgam #30 MO and I've been having trouble gaining a proper vision on the mesial and gingival floor when I'm dropping the proximal box. I'm used to operating at 7 or 8'o cock position when I work on #30, but I was just curious what would be an ideal chair position when dropping the box for class II #30 MO. Same question with a #19 MO as well. Thank you.

@StevensonDentalSolutions 4 жыл бұрын

Class II boxes on mandibular teeth are always more challenging than maxillary teeth. 7-8 O'clock is good for bur orientation, line of draw, mesial distal tipping, buccal lingual tipping but poor for visualizing the boxes. Try the 12 O'clock position for direct vision - it works most of the time, and have the patient lean towards you. Ultimately, the mandibular class II box approach will be a combination of different chair positions and the concept (albeit uncomfortable at first) of "cut a little, look a little", repeated numerous times. As you gain a subconscious awareness of your bur in 3D space through much practice (will take 100s of preps), and remembering the importance of bur orientation and finger rest, you can do less looking and more "blind" cutting. Some things in dentistry are very easy and some things are very hard - it's just the way it is...so, when you encounter a difficult prep, say to yourself, "okay, this is tough, it will take longer, be patient..." Best to you!

@jasonmohney8295 4 жыл бұрын

@@StevensonDentalSolutions Hello Doc, thank you so much for your thoroughly reply. Thanks to your advice, I've been trying different operating positions for dropping the proximal box on #30. A quick follow up question though. When I'm dropping the proximal box at a 12'o clock position, I noticed that I've been having lots of trouble with seeing the depth of cut I'm backing since it's a bird-eye view. In another words, it's hard to see how deep I'm going in with a bur. I'm not sure if I'm doing something wrong here, or if it just takes practice. I would appreciate your words of wisdom once again!

Thank you so much for this wonderful video Dr Stevenson. I have a question and concern about using the enamel hatchet. So, when we chip the little bird peak according to your description, down to the gingival wall, wouldn’t that create a sharp angle between the gingival and the axial, buccal or lingual wall of the box? And how to avoid this? Thank you

@StevensonDentalSolutions 5 жыл бұрын

Hi Doc - not really - creating a sharp line angle takes effort and requires forming it by sliding the hatchet into the proximogingival area across the gingival as well - simply removing the lip isn't enough, therefore it won't be an issue. The rounded line angle created by the 245 and refined by the 330RGS will remain as is, but if it seems too sharp, it's easy to correct with the bur.

@StevensonDentalSolutions 3 жыл бұрын

As long as the major retention aspects are present: occlusal convergence, proximal convergence and occlusal locks, most amalgam restorations have ample retention. If the size of the box is large, additional retention may help via the use of axioproximal grooves.

I think if I do mine S shape. I will take most of the distal buccal cusp away. How would you do this type of prep? Is there any restrictions for this type of prep where you don’t follow the rules...!? Thank you so much in advance for your help

@StevensonDentalSolutions 4 жыл бұрын

Forget the DB groove at first - simply prepare the class 2. Then assess the DB groove - if it is more than 0.5 mm away from the buccal proximal wall, leave it, and you're done. If, however, the groove is closer than 0.5 mm from your buccal proximal wall you have two choices: 1. Simply widen your box buccal to include it, or 2. Cap what remains of the Distal cusp FLAT to the pulpal but don't touch the proximal box from the gingival to the pulpal - it's like a mini-cusp capping procedure.

Hi Dr. So the buccal wall of the proximal wall should converge toward the occlusal right? i am confused about the lingual wall.Should it not converge at all towards the occlusal? Should it be completely straight parallel to the external lingual surface of the tooth? Because whenever i start preparing the priximal box, both lingual and proximal walls converge no matter how hard I try to not converge the lingual wall. My other question: For the proximal box of all molars and premolars is the same pattern to be followed : buccal wall convergent and lingual wall straight?

The lingual wall (or the non-functional cusp wall) is orthogonal to the gingival. This will require a slight tip of a 245 but towards the lingual to compensate for the convergent pear shape.

Thank you very much Dr.Stevenson . Can you share us please a video for underfilling MOD Amalgam with Harvard? .

Not sure what you mean by under-filling and Harvard? Do you mean liner/base?

We aren't using ZP cement much in the US anymore - there are better options, (GI, RMGI) - I have liner and base videos posted.

Hey Dr. Stevenson, I'm sure you want us to buy the 330RGS bur (maybe once I'm not a broke student anymore) but what bur would you recommend to use to refine everything without it? I've tried 330 in slow speed and it rounds the gingival too much but can work. 245 same thing. A 55/56 also works but sometimes is too aggressive. 169 is too pointy (too tapered) and ends up messing up my pulpal floor. I've used a 34 and that sometimes works but sometimes is too convergent and messes up my internal walls. Basically I can understand why you made the 330RGS, but not sure if you have another technique?

Take the 245 and flatten the bottom with a diamond bur. Presto - RGS 330 hack.

thanks! can u shape the appromximal box without the 10714 instrument?

@StevensonDentalSolutions 3 жыл бұрын

Yes, for sure - just requires attention to the bur position to avoid damaging the adjacent tooth. THe result will not have sharp internal line angles, but this probably won't be an issue unless it's an exam situation.

Any tips on how to avoid trauma to the gingiva using the hatchet? Mine keeps slipping and I'm practicing on a model but it would hurt if it was a real patient

@StevensonDentalSolutions 5 ай бұрын

Keep a stable finger rest and make sure that the hatchet is very sharp. We recommend sharpening them after each prep. Also, take very small "bites" with the hatchet...less force and easier to control. And finally, remember that we define with the bur (95% of the prep) and refine with the hand instruments (only 5% of the prep). Best to you and Happy New Year, Dr. S

Both 7 and 11-12. 7 is great for aligning the bur and starting the occlusal. 11-12 is good for visualizing the box and occlusal. 9 may be used with direct vision at any time...check out: kzfaq.info/get/bejne/fd6HpNOh0LrTcZs.html

Thank you so much for the demonstration. If I have to use force to break the chip near the box with the hatchet, does it mean the hatchet is not sharp enough?

@StevensonDentalSolutions Жыл бұрын

The hatchet may either be not sharp enough, or the remaining shell is too thick. Thank you for the question.
