My dentures are ill fitting or need replacing

Hi, it's Adrian from the Advanced Denture Centre. One of the questions we often get is what is the difference between, say, standard dentures and actually very customised dentures? I think the most important thing about customised dentures is really two things. One, listening to the patients and actually really understanding what they want with their teeth. And secondly, to spend the time with them to actually get as close as we possibly can to that goal. There are three things that we need to look at very carefully when we're looking at customised dentures. One is actually the appearance of the teeth, of course. We need to make sure that patients would like their teeth customised in a certain way.

We've all seen dentures where the teeth have been kind of selected and a certain color has been chosen and the teeth have all been set up very perfectly. And what you actually see is you can almost tell that it's a denture before the patient actually opens their mouth. The other side is you really need to make sure the bite is actually correct. So function is very, very important, and if the function or the position of the teeth aren't right, we then end up with a lot of sore spots. And the last thing is, of course, phonetics. When you change the position of the teeth, when you change the teeth or you have dentures that are made too thick, we normally find that the phonetics and the speech for the patients actually change. So the most important thing is spending time with the patients, listening to the changes they want with their new customised dentures, and really concentrating on the speech, the bite, and, of course, the smile.

Considering new dentures?

Many people believe that dentures last forever but just like natural teeth, dentures get worn out over time. Natural wear and tear combined with facial bone changes as you age may leave your dentures wobbly, loose or warped.

If you experience any of the following, you should come in for an evaluation:

  • sore and irritated gums and soft tissues
  • problems with chewing certain foods
  • headaches, neck, or ear pain
  • loose dentures that may even fall out when you speak or laugh
  • bone loss, thinning lips, sagging mouth, a change in facial features

Your face, jaw and tissues change over the years, and you deserve a smile that can keep up with these changes. Ill fitting dentures can lead to sores, infections, and other problems. Because of this, it’s likely that you need to have your dentures replaced or re-adjusted eventually. Why not avoid this and get a more permanent solution that actually preserves your oral health? Dental implants are the best solution to missing teeth and to ill fitting dentures.

Considering new dentures Fully customised denturesHi, it’s Adrian from the Advanced Denture Centre. If you’re looking at a new set of dentures and replacing your old dentures, there are a number of things that you really need to look at closely. These all really boil down to the experience of the prosthetist, or the dentist, actually making the dentures for you. And when we’re looking at denture manufacture, technology has moved on in many aspects.There are two things that we need to consider, of course. One is the technical aspect, actually, of the dentures. And what we’re really looking at here is the size and the comfort of the dentures. There’s this balancing act is, if we actually make the dentures too large, they will be really well supported and they’ll have a lot of retention. But the problem is, they’ll start encroaching on the size of the mouth and the tongue space, of course, and also start impinging on different areas, and therefore be uncomfortable. If we go the other way and make the dentures too small and comfortable, it means that we may lose support or we may lose retention.

The other thing, of course, is the cosmetics. And when we’re looking at the cosmetics, there’s two things that are very important. One is the height. As we lose teeth and the bone and gum shrinks, we lose vertical height of the lower third of the face. We also get this problem if we have old dentures and the teeth wear out. The teeth actually support the lower third of the face, so as this vertical height changes, we see the face change. So finding where this ideal vertical height is, is very important.

And the second thing in cosmetics is actually lip support. The position of the teeth actually supports the upper and lower lip. So if we change the position of the teeth, it means that we can get fuller or smaller lips. The problem, of course, depends on biologically what’s happening in the mouth. If the bone has shrunk or we put the teeth too far off the ridge, we then will find that the dentures will be uncomfortable.

So the art of making dentures really boils down to the experience of the person making the dentures, and we have to work within these biological limitations to try and create the best fitting dentures we possibly can.

Problems with lower dentures

Many patients with dentures experience problems with their lower denture all too often. The lower denture tends to cause more problems than the upper denture because the lower jaw moves more, is smaller and is more prone to shrinking than the upper jaw. The lips, cheeks and tongue also interfere much more with the lower denture and have a tendency to dislodge the denture when the patient is speaking or eating. These factors often cause the lower denture to move around – even to the point of falling out – or trap food underneath as the ridge shrinks.

To combat this problem, dental implants or an implant-supported denture are the most preferred and most successful solution.  By inserting metal implants into the jaw bone and connecting the lower denture to these, we can help stabilise the denture while still allowing for comfortable and easy removal of the prosthesis for cleaning.

Hi, it’s Adrian Kat from the Advanced Denture Centre. One of the common comments we hear from patients with upper and lower full dentures is the endless problems from their lower denture. The upper denture, of course, has the palate, so this area provides not only support, but also retention to the upper denture. So therefore, we tend to see a lot less problems from the upper denture.

On the lower, though, it’s a totally different story. It’s really because of the position of the tongue. There’s no palate, or there’s no area which will provide suction. So it’s really a horseshoe shaped of acrylic, and the lower denture is really held in by the tongue and also the cheeks.
One of the issues with the lower denture is it tends to move around a lot. And yes, we can increase support by increasing the size of the lower denture, but then, the problem, of course, means that it starts to impinge on the space of the tongue and becomes quite uncomfortable.

There are options for the lower dentures. I suppose there’s three. One is to make the best fitting lower denture possible. So that’s one option. Secondly, we can do overdentures from either your existing denture or a new denture. Now, overdenture means that we place two implants in the lower jaw and we use press studs to hold that denture in place. So the denture is still removable, you still take out at night, but at least it has a secure place to clip into.

And the last option is, of course, implant treatment, where we’re actually using all-on-four treatment and placing four implants and placing a fixed bridge. This is a very different treatment because, of course, it’s fixed and it is not taken out of the mouth. The teeth are also much smaller, and therefore much more comfortable for the patient.

Difference between dentures and All-on-4

All-on-4 is the term used for the revolutionary solution of restoring a complete arch of teeth to a patient’s mouth.

Dental implants not only last much longer than traditional dentures, they also require less maintenance, and instead of sitting passively in a patient’s mouth, dental implants actively conserves the patient’s jaw bone and oral health.

Where dentures need to be replaced every few years, dental implants are a more long-term solution. And to make dental implants even more attractive, the All-on-4 solution offer all the benefits of dental implants but for less hassle, fewer visits to the dentist – and at a more affordable cost. This advanced technique makes it possible to restore a full arch with as little as four specifically designed dental implants as anchors for a customised prosthetic dental bridge. What you get is a new set of teeth that look and feel just like your own natural teeth.

Hi, it’s Adrian for Advanced Dental Artistry. A common question we get asked is, isn’t All-on-Four Bridge exactly the same as the denture but screwed in? They’re actually very different. When we look at a denture, there’s two parts of the denture that are not on the All-on-Four Bridge. One is actually this flange. And this flange actually covers just under the lip.

And the reason for the flange is to really extend the denture so that it’s more supported. The other very important area of a denture is actually the palate. And the palate, of course, this big seal, this goes around the entire upper part of the mouth, this is what actually gives the denture suction and support. So, when saliva gets between the plastic or the acrylic and the gums, that moisture actually forms suction and that’s what retains or gives the denture the retention.

There’s always problems with this of course because it takes up so much of the mouth that it does change usually the tongue position, and it actually gets quite uncomfortable sometimes having it there. If it’s extended too far, it can actually cause the patient to gag, and we normally find that patients do complain of altered taste because a lot of their palate, which does have taste buds on, is actually covered.

When we look at All-on-Four Bridge, it’s very different, we try to keep the All-on-Four Bridge as narrow as possible. And this means that if we can keep it about the same width as the teeth. The most important thing here though is the placement of the implants.

The implants have to be placed very precisely so that the screw hole can actually exit just at the very top or the back of the front teeth. If this happens, we can keep the bridge a very, very small edge, and it’s really just the thickness of the bridge and a tiny bit of pink acrylic that replaces some of the missing gum in the bone.

So when you look at both of these devices, the All-on-Four Bridge, and the full denture, there is a huge difference in the size of them, and naturally, the comfort and the last thing, of course, is the retention. One is actually removable, that, of course, comes in out, and the retention of that really depends on the size. The bigger we make a denture the better the retention, but the more uncomfortable it is.

When we look at the All-on-Four Bridge though it’s the placement, the careful placement of the implants and the screws that actually hold it in place. But because of such a narrow row of teeth, it is very comfortable for the patient because there’s a lot of room for the tongue.

Treatment Length

Generally 3-4 weeks, but there are express options available as early as a week dependant on patient availability for check-ups.
