A New Era In Dental Technology
A few months ago my team and I visited the Dental Technology Show at the NEC Birmingham and were dazzled by all the fantastic new technology that was being presented this year. But there was one piece of equipment that really caught my eye, a scanning technology by dental wings. The dental wings scanner is a fairly small unit which has a sliding door at the front and inside sits an unsuspecting set of instruments; a small rotating table and digital laser. Now this isn’t new technology, as such, but after being given a demonstration I quickly realised how advanced the technology is.
Here’s how it works; We take an impression of the mouth, cast the impression with plaster as usual and from there we would normally start to design a wax pattern for casting a metal denture frame work. This is very labour intensive, very messy and extremely difficult and requires a registered dental technician. however, with this scanner, you can simply place the model inside, press a button and the lasers digitise the plaster model into an incredibly accurate 3D vector image. but that’s not the best part, next the computer program blocks out all the undercuts and designs a the chrome frame work and all in the blink of an eye. Up until now, I’ve never seen this or even heard of it. Before, after the model had been scanned, it was someone’s job to then start designing the metal frame which as you can imagine, takes a lot of time, skill and knowledge. So I was blown away and completely sold. But that’s not all! this scanner can also crown and bridge patterns, implant bars and placement guides. This is great for all of the team here at the Smiles Centre because we are doing more implant work that ever before and the trend for people to be having implants doesn’t seem to be slowing down. As you can imagine, this sort of technology doesn’t come cheap and its certainly wouldn’t save me money, at least not for a good few years but, I brought it anyway. Why? Simply because I know that it will allow us to give our patients the very best of care, and we all deserve that, each and every one of us.
Have any questions or thought on this subject? I love to here them, post a comment below.
The human body has evolved to eat a variety of food and whether you decide to eat meat or vegetables, our teeth and jaws are designed to eat both.
If we look at dogs teeth we can see that they are very sharp but we can also see that the teeth lock together when the jaws are closed. IF you observe a dog eating you will notice that the lower jaw just goes up and down whilst eating. Now, if we look at cows teeth we will see that the teeth are quite blunt and even more obvious is the way the lower jaw moves as the cow eats. It’s a very exaggerated rotational movement and the tough abrasive diet of the cow is ground finely before it is swallowed as opposed to a dog which swallows large chunks of soft digestible meat. Us humans vary in the way we eat. Some of us eat like cows, some like dogs and others eat with a combination of both.
Most problems with dentures are caused by the way we eat. It is relatively easy to make a denture that fits a persons mouth but, getting the denture to stay in place while the person eats is the difficult part, especially if that person eats like a cow with a rotational movement as this can cause the dentures to tip.
There are many techniques that we use to reduce the tipping of dentures whilst eating and it all comes down to the placement of the acrylic teeth and shaping them in such a way that minimises tipping. As a clinician providing dentures, I always prefer the patient that eats like a Dog!
Eating like a dog has its own problems too because denture do not last long if they are used to tear food. I guess the perfect patient for me would be one that eats like a mouse, taking small nibbles!

Good job, Simon!
I think out new website looks great! It’s easy to navigate and provides all the information you might need about dental treatments that we offer. I also like the “Meet the Team” part where you can get to know more about our dentists, technicians, nurses and admin staff. Oh, and I like the photographs! 🙂
It is getting close to the completion of my Dental Nursing Diploma and it is a busy time of a year for me.
Apart from the Dental Nursing Exam in October, there is many other assessments that I have to pass before January. The next two weeks will be particularly busy as I need to put together a presentation on “Oral Health Products and Oral Hygiene”, and also, prepare an “Oral Health Advice and Promotion” simulation.
My assessor, Kim, is coming to observe me in the surgery in a couple of weeks. I have already passed Fillings, Extractions, Dental Check-ups, Consultations, X-rays and all Denture Treatments.
I still need to complete Root Canal Treatment, Crowns, Bridges and Veneers. I feel confident about these so hopefully Kim can tick all the boxes on her next visit to Swindon 🙂
See you at Smiles!

A reline to a denture involves removing a layer of acrylic from the fitting surface and then replacing it with new acrylic that will fit the contours of the mouth better. It’s a great way to have an existing denture updated due to wear and tear and also changes to the mouth.
However, there are several downsides to this procedure.
Firstly, even though some of the original acrylic is removed, the denture nearly always ends up with more acrylic than before, the degree to the amount depends largely on how old the denture is, and this extra acrylic adds weight to the denture. Which is bad news especially if its an upper denture.
Secondly, the material used to reline is not as strong as the actual original denture acrylic in most cases, so relining can make a denture weaker. Although is some situations, the extra thickness of acrylic can make a denture stronger.
Thirdly, not all dentures can be relined. Metal dentures for example, are very difficult to reline and can only be achieved successfully with section relining. this is where only a part of the fitting surface is replaced, after an extraction for example.
You’ll also need to take in to consideration the cost of the reline compared to having a new denture made and the time it takes to make a new denture. You can keep your old denture while your new one is being made but having an old one relined will need to be kept while the work is carried out. Its also worth noting that if a reline fails, you cannot go back to where you were before the reline was carried out. This is very rare but I have had people come to me to sort out failed relines and sadly, there isn’t much that can be done other than having a new denture made. So, a reline really is a great way of getting your denture to fit again but it’s not suitable for everyone!
You can find out more about relining dentures on our website here or if you are thinking about buying a new denture the you should definitely read my Denture Guide Booklet, its free and you can get it in printed copy or a PDF download version is also available.
