Permanent or removable dentures?

Posted by Dental News Team On November - 13 - 2009

Permanent or removable dentures?

wasserglasCost of dentures, free dentures, Chinese dentures, cheap dentures – common queries, but the most important question is: permanent or removable?

Patients are often faced with a choice among different types of dentures, either removable ones or ones that stay in the mouth. Here the pros and cons at a glance:


Permanent
Pros: comfortable, looks better, good for your self-esteem

Cons: usually very expensive

-

Removable
Pros: usually cheaper
Cons: a reminder that you’re getting “older”, does not look as good, you run around the hospital toothless

-

Removable dentures are often touted as being easier to clean, but this is not exactly true: both kinds can be cleaned if you do it right. Of course, the kind your dentist uses more often will be the kind they are better at and recommend.

-

It’s fair to say that if you already have removable dentures and are happy with them, then you can go ahead and save your money. Get a new set from a dentist who recommends them. If you prefer permanent dentures, then look for a dentist who prefers them too!

Periodontitis or Periodontosis?

Posted by Dental News Team On November - 12 - 2009

Why do so many dentists still refer to periodontitis as periodontosis?

periodontitisIn medical terms, the ending –itis refers to an inflammation, while -osis stands for a degenerative dysfunction caused by problems inwith metabolism.

-

Arthrosis, for example, refers to a degeneration in a joint due to excess strain on that joint. Arthritis, on the other hand, means an inflammation of a joint, a bacterial infection after an accident.

-

The terms periodontosis, periodontopathy and periodontitis come from the word “periodont“. This refers to the bone and tissue complex which holds the teeth, i.e. the anchoring system which attaches the tooth to the bone (perio = around, dont = tooth). This periodontal apparatus consists of the gums, bone, periodontal membrane and root element.
-

For a long time it was impossible to isolate bacteria in the gum pockets of patients with periodontitis, since it was common practice to use oxygen in germ cultures. But these bacteria were able to survive in gum pockets because of the absence of oxygen there. It was assumed, wrongly, that if there were no bacteria present, then this was a case of –osis! However, 25 years ago methods used in molecular biology finally made it possible to prove the existence of bacterial DNA, later on special incubators were used to grow these bacteria – in the absence of oxygen. And bacteria means -itis.

-
This is not just word-play, but crucial to finding the right kind of treatment. An inflammation requires a different kind of therapy than does a degenerative dysfunction, so you have to make the right diagnosis in the first place! But although scientific proof was found 25 years ago, doctors  are still in the habit of using the term periodontosis.
-

Periodontitis therapy requires two things, first that the doctor actually knows the illness at hand and second, the causes. Failing any of these two things prevents successful treatment. But gathering enough information takes time.

Don’t take chances with your smile!

Posted by Dental News Team On November - 12 - 2009

A beautiful smile is not just a matter of luck, using “Smile” geometry can help
you get it!

zahnaesthetikIf a face looks appealing to you, this has a lot to do with the person’s smile and the shape of their teeth.

Sadly, dentures are not always produced with these factors in mind, so that dental crowns often have an unnatural look to them. This video shows what goes towards making a smile attractive.

Of course a good denture costs more, and takes longer to make. Moreover, a dentist cannot simply communicate a color choice to a dental technician …

Finding the right braces

Posted by Dental News Team On November - 11 - 2009

Does it matter what type of braces I use to fix my teeth?

zahnspangeYes, because each type has its own pros and cons.

-

Removable braces only work when a child is still growing, when it’s still very young.

Aligners do practically nothing to fix teeth which are twisted out of position, especially cuspids.

The lingual technique cannot be used in many cases.
-

So which treatment is right for you?

Your orthodontist (a dentist who specializes in braces) can tell you. A „real“ orthodontist is one who has done at least for years of special training and now concentrates on doing „braces“, he or she even gets somebody else to pull teeth.

Although dentist are legally allowed to provide orthodontic treatment, this type of treatment usually lasts a long time (over 2 years) and may cause damage to the teeth or periodont.
-

Ask your orthodontist what type of training he or she has done!

Professional dental cleaning is good for your heart!

Posted by Dental News Team On November - 10 - 2009

Our immune system has millions of micro-organisms and viruses to fight every day!

bakterienUsually it wins, if not then it doesn’t take long to find out – we get sick. Our bodily orifices are a gateway to pathogens. This is why the largest openings  (mouth, rectum, genitals, ears, nose) are equipped with special „defense stations“ used by our immune systems, e.g. the ones in the mouth, the tonsils.
-

But let’s talk about the smaller „orifices“ for a moment, such as the nails or teeth. Teeth are usually „joined“ to the gums; there is normally no hiding place for bacteria in a healthy periodont. However, this changes in cases of inflammation of the gums.
-

The inflammation destroys the tooth-gum complex, moreover blood vessels „swell“, and all this makes it easier for the bacteria in our mouths to get into our blood vessels. Doctors call this „transient bacteraemia“, which can be fatal to patients with a heart condition. This is because:
Normally bacteria are destroyed by the immune system, unless the bacteria manage to escape detection by the immune cells in time. Bacteria especially like doing this in „thrombotic vegetation“. This is a kind of „blood crust“  in the blood vessels.

Mainly consisting of blood corpuscles, this structure usually forms in places where the flow of blood is somehow obstructed. These „disturbances“ either occur naturally, as in the case of congenital heart defects, or they can be acquired, e.g. when a patient has artificial heart valves, or artificial vessels.
-

If bacteria manage to get into our vessels, they can “hide out” in these blood crusts and are safe from our immune cells. When immune cells float by they don’t really„pay attention“ to blood crusts, as they are a part of the body. The immune system only attacks foreign elements. But inside the blood crusts, the germs can multiply until there are so many of them that they start to disperse. The immune system is no longer capable of fighting off the invaders by itself – and depending on where the germs are, organs in that part of the body can become infected.
-

Regular dental cleaning perfomed by a professional makes your teeth and gums more resilient, reduces the harmful germ flora in your mouth, and can even protect your heart, as stated in the title!
