hi everyone dr mack again with another video today today's video is all about giving you a basic understanding of the rubber dam task i get a lot of queries a lot of questions regarding sheet selection clamp selection the basic outline the planning now i do help dentists around the globe and dental students with my online short courses and comprehensive courses for the foreign train dentist exams i will share the link below in the description of the video in my detailed comprehensive technical course i do have technical auskey sessions as well in which i have eight videos for my rubber dam course which basically explains you outlines you in detail about the basics the foundation of using rubber dam which clamps to use how to plan your cases and showing you every single place on the model so you get the basic outline and everything is nice and clean for you but today's video i thought i'll share the first video of my rubber dam course with everyone just so everybody can get a bit of a basic outline and a bit of a basic understanding when they're dealing with rubber dam tasks so hope this video is helpful for everyone do share your feedback with us in the comments below and we'll keep sharing some useful information with everyone [Music] hi everyone uh and welcome to the robert dam class today a lot of confusions people trying to do again whenever you get confused focus on the three adc laws that i created basics you're not here to impress anyone just focus on passing the exam so whenever we see all these clamps right there when we get confused we won't be using all of them i want you to focus just on five clamps and that is it don't worry about these other fancy looking um rubber dam sheets okay we just focus on this purple one we get in the exam okay the description of all these which the name of the sheet and all that will post it for you so you don't have to worry about it okay so we need to focus on five clamps we need to focus on the basics and it just works every single time less stress okay so first thing what you need to understand is what is a winged clamp and thought what is a non-winged clamp or we call it the wingless clamp now look at this clamp here if you notice is a clamp here there's no wing on the side comparing it this one it has a wing here on the side so this is a winged clamp it has two wings on the side okay so it rests on it now the advantage of a winged clamp is that you can assemble everything outside and once you've assembled all your rubber dam you just need to place it in the mouth or on your mannequin becomes a lot easier with a winged lamp wingless clamp because you cannot do this you basically have to apply this first in the mouth and then you follow it with the sheet on top and that's how a lot of people do even in clinical life as well okay either some people do the clamp first on the tooth and then apply the sheet on top or they put the sheet like this first after the punches and apply the clamp on top like that because they don't have the wings to hold it either way whichever works for you either you assemble it outside or you know mix it up like inside the mouth like clamp first or sheet first and clamp on top it's your choice what i have seen is in adc if you're getting the winged clamp then don't make your life difficult just do all the assembly outside so you just place it in the mat now when we talk about rubber dam we will not be using all these clamps don't worry about all these clamps okay we will only be using five clamps and i would really like you know advise everybody to just worry about these five clamps don't worry about all these 200 clamps that we see okay the the most important is not the most important but the there's one clamp called as a 13a and 12 a clamp the note if you notice the reason why they call 12 error 13a is if this is your first quadrant the 12a goes on your first quadrant 13a goes on the second quadrant and if you notice on these clamps what will you see is there's a bit of a big cravings on the one side and this small on the other side so this basically tells us this is for the upper clamp now the same as with four steps the right and left is different the same with 13 and a 12-way is different if you notice the buckle the big one goes on the buckle now how to know which clamp is which always remember this big thing that you see that always stays on the distal now when i say this thing stays on the distal now this is my demarcation if i say that's the first quadrant this one and if i would place it like this the 12-way the buccal portion is coming on the palatal that means this is for the second quadrant not the first quadrant so if i hold it like this hold my clamp it just fits in just like this okay so the big one on the buckle small one on the palatal because that's how the upper tooth is it's smallly on the palatal one root and then buccal have two roots mesobuccal distrobuckle so they just goes like this same same way if you're talking about 13 a 13 a is for the first quadrant so basically what we're doing is just like that okay so the buccal big one goes on the buccal smally one goes on the palatal so the upper teeth whenever you talk about upper teeth we want to look at 13 a 12 weight these are the two clamps okay if we talk about interior tooth and sometimes there's a front tooth and all that we need to talk about this clamp right there number six clamp and you go in like this now it also depends on the isolation protocol we want to know for what procedure are we doing it is it for an endocase is it for a filling is it for um is it for something else so it depends on the procedure the rubber dam things changes as well okay so pointing out 13a for the first quadrant 12a for the sec second quadrant okay and then we have this number six clamp for the anterior tooth all right and then very important this clamp here number four now with the lower teeth you will notice that we have similar you know we have mesobuccal mesiolingual disto buccal distilling or one distal but because of similar roots we have clamps like these that sink in really nicely again the distal goes here and then just on on top so that's why if you talk about lower teeth the four clamp can go either on this tooth either on this tooth you don't need to worry about the upper teeth that's why the upper teeth have 13a and 12a the lower one number four does the work for you a lot of people like using instead of four they like using a seven or a seven a now the difference between whenever something says a to it the difference between a is that can you see the seven there look at it's a winged clamp but if you notice closely it's flat so the clamp when it hits the tooth it's very straight right that means it's good but it's less retention when i compare that with an activated clamp which says 7a 4a 13a whenever you see a on top of that letter that means there's an activated clamp and you look at like this that means this is activated now so the hooks of the clamps are directed down that means it's a bit more on the activation side this is mostly for the clinical scenario when we have subgingival defects and we want to be more retention in your case either way works really well but generally if you have activated one it's not a bad idea the only disadvantage is because it's activated these are pointy the clasp so what it happens is sometimes it pierces through your dam that's why sometimes a non-activated one is not a bad idea however when you work on it as i said you need 13 a you need 12 a you need number four you need number six four and then we need one of these ones double zero for the premolar that's pretty much it if you work on these five ones if you notice again this is a non-activated and you would notice the size of the premolar is smaller that's why it's here you can put it on a canine as well you can put it on a premolar as well so these these are the clamps are well over you don't need too many clamps so don't worry about thousand clamps and all that if you work on these clamps you pretty much solve all the scenario okay now we need to we need to work on the basics whenever there's an arch like this okay arch like this and someone's saying that okay now i have a case in which i have one teeth here central's latrolls k9 okay this scale is big there's a small premolar premolar make it like a box so it's less confusing and then we have a big molar here okay now someone tells me that and there's a second molar here okay now someone says that you have an endo for lower six four six ideally what we to do is whichever tooth you want to isolate if they say 4 6 then ideally you would like to put the clamp on the tooth behind it one to distill to it the reason for that is once you can visualize that tooth a bit better when you put that clamp on the same two the visualization is a bit difficult because you can stretch the dam a bit better like that okay rather than here and then this fold just comes on top second reason is just in case you put the clamp on this seven here and something breaks or you have a tear on it the isolation was meant to be done on six not the seven so we can just patch it up with a bit of a liquid dam or liquid rub it up and then it works well so it's a bit of a safety measure as well so on a rule of thumb you wanna always say that if you're talking about any two talking about three six then you will try to do one teeth on the distal if you're talking about canine then we're talking one tooth on the distal if you're talking about the front tooth then ideally to stabilize the dam otherwise your dam will not be stable what you should be doing is bring it up till the canine so if i have a central incisor i would bring it from k9 to k9 to make the rubber dam stable if they're telling me to do a four or five this one then i would ideally put the clamp on the six and then i can isolate three teeth one on medial one on distal and this is the two that i'm working on but my clamp goes on the distal so even if there's a pairs to it or there's an opening to it it's not affecting my working site that's how it works basically okay now the only difference to this scenario is that you want to cross the midline on the anterior tooth to make it stable you want to go distal to the side in front to have a better visualization and just to have a preventative as well that you know just in case it breaks or has appears to it your working side is not affected endodontic excess protocol so if they say we have a do an endo on one tooth which is 2 1 then you can just put a clamp on this tooth only and it works if they say you have a endo on four six then instead of doing three teeth you can only do one teeth and it's gonna be fine okay so normal protocol what we want to do is for interior tooth we want to cross the midline to make this stable otherwise you'll notice a lot of people do this and the dam is like this this bend it how bend it like this so you want to make sure it fits on the face so it's not too much stretch on one side number two is whichever tooth you want to do we want to have a tooth in front and have a tooth behind it so we basically try to do three teeth as a pair and then the clamp goes on the further back tooth which is the distal so your site is this you have one tooth in in front one two that the breath and then this covers it so basically that's how it is the only difference to this is if you're doing an endodontic axis that's the only time it changes okay let's talk about the placement of rubber dam
