Invisalign clear braces compared to other braces

Most people have heard of Invisalign as a brand name for a particular kind of clear braces treatment, and if you need Invsalign in Dublin, Swords Orthodontics has been providing this kind of treatment for almost a decade now.

That said, since then, Invisalign has evolved a fair bit. For a start, the actual system is a lot more predictable and effective at moving teeth. The other way it’s changed is that there are now many different types of Invisalign treatment options.

People think that Invisalign is only for small orthodontic problems, but that’s not always the case. Invisalign can treat some fairly complicated situations and when we need to do that, then Invisalign Full is the standard treatment for most patients.

On the other hand, some patients do have some minor problems that need “ironed out” and that is where Invisalign i7 comes in. It’s just 7 aligners, each worn for 2 weeks and so the treatment only takes about 14 weeks. Same clear brace aligners, same procedures, but very definite treatment goals.

Of course, there is a limit to what we can achieve in 14 weeks, so when choosing whether a patient is suitable for an i7 treatment, a fair amount of care and experience is needed. It tends to be a good idea for people that might have had orthodontics once and didn’t wear their retainers as much as they needed to, and now they want their teeth straightened out, but the major movements of their original orthodontics have been done. It’s also handy for someone with small spaces or rotations in their teeth.

Very few patients actually ask me for Invisalign i7, because very few patients know it exists and honestly they may require treatment that is extensive and isn’t suitable for this version of Invisalign. But if there was a minor problem that needed to be put right, a course of Invisalign i7 might sort it out inside 4 months. If you think you might benefit from i7, call us today on 01 810 7622.

"What's my IOTN?" IOTN explained for Irish Orthodontics, how it affects you and your children

I get a lot of patients asking about their IOTN, so I thought I should explain it a bit and why it’s important in Ireland.

 

 

It stands for Index of Orthodontic Treatment Need. It was developed in the late 80s in the UK, based on a Swedish model from the early 70s with the intention of having an objective comparison of orthodontic situations to decide what would be a reasonable use of public healthcare to provide dental treatment to correct the problem.

The most commonly part of the Index is known as the Dental Health Component (DHC).

There’s a 1 to 5 scale, with 1 …

Dentistry in general, and orthodontics and the various specialties in particular, can be an isolating sort of profession. You spend most of your time and energy working and thinking in a zone within the reach of your relaxed arms, in a location about the size of a small spare bedroom. …

Didn't know she didn't smile

Had a young patient in for the first time last week, accompanied by her mum. They both knew what needed fixed - a top tooth biting inside the lower teeth instead of outside them: a crossbite.

I went through my usual orthodontic assessment for a new patient, measuring this and that, but I also asked “would your teeth stop you smiling for a photo?”

“Yes.”

I could see her mum’s face change tone, and she said “you never said that, you never told me you didn’t smile.”

At the end of the appointment, after she’d left the room her mum said the same thing to …
