全口义齿软衬垫制作过程

预位永久软树脂操作流程，软树脂的充电方法，这有一个倒凹，一会我们要把这个倒凹填起来，你看这个倒凹很大的，如果是他前面有鼓凸，这有倒凹，一定要把它填起来， 所有刀的地方都要用软树脂把它填下来，这个以后填的时候要填成这个样子才可以。我们现在先把软树脂的他的预留的零点四的空间先先给他弄好，先用一个零点四的蜡片，我们把它先做出来，大家看一下怎么做，我们先从这 我们要使用的是这个辣片， 这个是我们要使用的模具， 我们刚才是这样拿出来的，然后呢这个地方是需要填倒凹的地方，我们要用，我们用软竖式先把倒凹填上， 这个上面是不需要涂分离剂的，因为软树脂呢，他跟他不结合，跟石膏不结合。我们先把刀填起来， 这是零点四的，因为我们刚才是在零点四的辣片上做的，他的厚度是零点四， 这是刚才我们填刀的地方，填的地方呢，这个地方有双层的，他肯定厚，我们要把它去掉一部分， 好边缘修整，把它边缘一定要修好，他做出来就很规矩了，少的地方要 贴上去，多的地方要把它去掉，我们检查一下边缘，全部要让它倒边， 边缘要倒边，并且边缘很规矩很工整。将软树纸粘接剂使用前摇晃均匀，然后涂在我们刚做的软树纸上，我们现在把它扣上合上去，合上去以后呢我们就开始注塑， 注塑冲胶，我们使用的是意味免煮牙脱粉，将免煮粉调配均匀后放入物料桶中，通过液压气匀速冲胶， 当多余材料从排一到一出时，葱焦即完成。反拧一下液压螺丝，轻轻压下放置台，取下主牙盒， 拧上排一道螺丝，拧上加压螺丝，将主压盒放置高压锅内，在高压锅内加满开水，直至水溢出，待水面没有气泡冒出后，盖上高压锅盖，拧紧加压螺丝，浸泡半个小时。半小时后小心提拉释压阀门，注意防备蒸汽烫伤。 卸下加压螺丝，将高压锅内的水倒出一部分，锅内剩余的水分足够，盖住主压盒即可。最后接通电源，在高压锅后面打开开关，将温度调整至一百度， 将煮制时间调整至四个小时， 等待自然冷却取出后即完成。玉为永久软树脂 沉淀效果展示。

hi， my name is barry perezian， i'm a denturist and the owner of the prisey and denture clinic in windsor ontario and today i wanted to put together for you a little video on how dentures are made i've always found that something most of my patients are always very curious about basically how a denture is made from start to finish， so i hope you'll find this interesting and you might even learn a little bit along the way so the first thing that happens when we start making a set of dentures is we take impressions of your mouth the impression is just all this kind of gooey plato stuff that's put inside your mouth and it basically takes a mold and from that mold we pour up with what we call stone basie just off harder version of plaster paris we pour up these models and then we basically have a duplicate of exactly how your mouth looks this is somebody's upper jaw who has no teeth anymore and this be somebody's lower jaw who has no teeth left anymore then once we have these models then we would go ahead and take a bite which is basically finding out how the person bites together okay， so here we have the person's bite now now what the bite or what we did in the business call would call is a bite blocks or bite rims or bite registration this would all normally be made of whack so it's kind of a pinkish red color in this case this this is all made out of stone this kind of yellowish material because this set of teeth that i'm setting up right now is for a competition across north america for dentures ah it's through a company called canceller um so they provide the bite and it's all made out of stone instead of wax but this is very similar to what it would look like and what it does is it gives you a registration or a relationship on how the upper your upper jaw would meet up with your lower jaw and so we're basically taking an impression of how you bite together okay， so now that we have our bite or bite registration on how your jaws meet together we need to do what we call articulate the case and how we do this is we mount everything onto a articulator a articulate later is basically a fake jaw it opens and closes and these little round parts here these would represent the joints to your jaw and we can adjust the angle of them and they can kind of move from side to side just like your jaw would and so that's the articulator there's different styles of articulators different companies make different articulators there's also very simple ones we in the business typically just call hinge articulators these are just simpler case is not as involved but basically an articulator like i say is basically just a artificial jaw okay， so here we have our models that have now been articulated onto the articulator so if i were to take this all apart now and take the bite registration out of there now what we're left with is we're left with a relationship of how the lower jaw meets with the upper jaw and from here we can start setting up the teeth because we pretty much know how your jaw works okay， so here we go where the very beginning stages of starting to set the teeth up now a lot of people think that when we make a denture that we actually， physically make the white portion of the denture the actual teeth themselves， but we don't we buy the teeth from a manufacturer and they are already made they come on little cards like this the teeth are all held in place with wax this would be an upper your upper front teeth these would be your lower front teeth and these would be all of your molars and pre molars so that's what it looks like when we get ready to start setting up a denture and what we do is we take the teeth off this wax card and then we position it in the denture the way that we want and that's when we can start playing around with how the denture is going to look and everything okay， so i have the two front teeth on the top setup right now and as you can see all the kind of pinkish red stuff right now is wax we heat up wax， we put it where we need to and that's what holds the teeth in place when we're making a denture so i'll show you how things progress as i go along here okay， so now that we have the try and or the setup all done it's all just kind of roughly done in wax now what we need to do is we need to go and do what we call a wax up and that would be making the gums or the pink portion here making those look naturally they normally would in your mouth so that is what i'll be showing you next okay， so the wax up of the denture is now finished so what i've done is all this kind of reddish purplish pinkish stuff is all wax that i've just heated up and put where i wanted to and then i kind of carve it the way i want to to make everything look like a natural tissue in the mouth， there's a look at the upper on the inside here is the lower and so what we can do now is we can get ready to actually go ahead and finish this denture and turn all of that wax into plastic all right， so now it's time to do what we call investing the denture？ so what happens is we use what is called a flask and this isn't the kind that you drink out of a flask is a metal container they typically come in two halves and what we do is we encase the denture in plaster inside the flask and i'll show that to you in the next steps it'll make a little bit more sense there's different kind of flasks this one here would be used for going in a microwave this one here is just your regular kind of run of the mill press flask the one i'm going to be using here these are injection flasks where the acrylic or the plastic is actually injected into the flask so let's see how that's done now okay， so now we have the denture in half of the flask so far and as you can see it's all or at least the model portion is all encased in plaster and so what this is going to do this half of the flask is going to hold the model which is basically duplicate of the mouth it's going to hold the model in place so that way it will stay exactly where it's supposed to now the next step is that i'm going to put the second part of the flask together and then we pour plaster on the entire inside so that way we are completely encasing the denture and plastic but once that's done the two halves of the flask will still be able to come apart and after we have softened the wax which i'll show you in a little bit after we've softened the wax and you open up the two parts of the flask， the teeth are gonna come out in one part of the flask and the model here will come out in the other part and where all of the wax used to be that will all be boiled away and will be left with a void where the wax used to be all right so i've poured in the plaster into the second half of the flask now so now the denture or the waxed up denture is completely encased inside the plaster for those of you who might be wondering what these little black pieces are these are just dummies just basically spacers for where components for the injection system are gonna end up going， so all we gotta do is we have to wait for this to dry then i'll be heating the flasks up and boiling out the wax so here we have the denture after the wax has been boiled off so like i said in the beginning on one half of the flask we have the plaster which has now held the model in place and on the other half of the flask， we have the teeth which are held in place so the wax has all been boiled away you just put it in a machine that heats it up and then that softens the wax you open from these two parts up the wax kind of pours out and then you put it back in the machine and sprays water onto the models and just rinses off any remaining wax and we are left with this here then what we do is we coat everything with what we call separating fluid it just stops the acrylic from sticking to the model afterwards so now we just have to wait for the acrylic to be ready to inject okay， so here i've got the flask all together i've got the acrylic in this little capsule here so what we're gonna do next is we're gonna put it in the injection system and let the the injection system basically push the acrylic into the flask which will like i said before this is gonna let it take up all the space where the wax used to be so now i have all of the dentures， which have been packed or injected with acrylic now now i have them in the what we call a poly polymerization unit curing tank basically which is going to cure the acrylic or harden it this process here that i'm going through right now is going to take about seven and a half to eight hours so when we open that up the dentures will be finished or at least the acrylic will be finished curing and then we can trim the dentures up okay， so our cases are finished curing so the acrylic is all hard inside the flask now so now what we need to do is we need to take everything out of the flask？ so this is how we do this here and there you go so this is all the plaster that was encasing the denture so let's go ahead and we'll get all this plaster off here and there we have the denture which is all now made it in acrylic this is what it looks like when it comes out of the flask okay， so here we have the finished product now the denture has been trimmed and polished from when it was first taken out of the the plaster and we're now ready with a denture that's ready to go into somebody's mouth， so as you can see here a denture doesn't really need to look like a denture the teeth on this are not all perfectly straight they they aren't bright white if i turn around like this you can see that again up at the front that the teeth aren't perfectly straight like a picket fence so you can have dangers made that look natural like what our natural teeth would so something to keep in mind if you ever need to get it done unless you want that perfect smile that's perfectly fine so anyways this is how we do it from start to finish hope you learned something。
