About partial dentures with invisible wires
Q. I have had the second to last molar on my lower jaw removed and now there is a bridge connecting my deepest molar to the third molar. I recently went to the dentist and learned that these two molars had gingivitis so I got them removed. Now I am missing all three of those teeth.
The dentist recommended that I get partial dentures covered by health insurance, but he also told me that my good teeth that the wires clasp onto are susceptible to gingivitis. When I mentioned that I am worried about the wires being visible, he suggested implants. But, I am afraid of surgery. Are there partial dentures that are better than those covered by insurance and have invisible wires?
A. Currently dentures made using Japanese health insurance use metal springs called clasps. The clasps are attached to the teeth, but there is no adhesion.
Because of this, when the dentures move the teeth also move. These movements exert a force that can lead to the tooth gradually becoming loose and falling out.
These dentures are constantly moving inside of the mouth because they are attached to the teeth using springs. When we dentists extract teeth, we do so by exerting a side to side force. It is the same exact movement caused by insurance-covered dentures.
Germany, which is a leading country in denture technology, doesn't even teach about partial dentures that use clasps anymore at national dental universities. This is because these kinds of dentures cause tooth loss.
There are a few types of dentures that do not move around in the mouth and that are nearly undetectable as dentures. Some of these include Konus Krone, Riegel telescope, CSP, and Milling dentures.
None of these options are covered by insurance, but they have invisible wires and are so comfortable to use that they become a part of your own body.
Let me tell you how we would treat 3 missing teeth with partial dentures made using Riegel telescope.
Subduction (movement) of the dentures can be great when biting with insurance-covered clasp dentures because they use simple metal springs that grab onto the teeth. This force is transferred directly to the teeth and will eventually cause them to become loose due to wiggling.
In contrast with this, Riegel telescope dentures will link and secure the 2 teeth used as a foundation, and those teeth will be double crowned. Retention force is provided by a small locking mechanism and the dentures are held firmly in place by closing this lock.
The subduction (movement) of dentures made using Riegel telescope is limited to 300 microns when biting.
Of course this provides a firm bite and the dentures feel like your own teeth. It can be said that Riegel telescope dentures feel as much a part of your own body as implants would.
