Dentures over implants have gone through several developing stages in order to provide satisfying comfort level during speaking and chewing.
In the field of dentistry, during last few years, development of implantology has been enormously significant. It brought new techniques and materials that have improved our dentist ability especially in the area of replacing missing tissue by functional and aesthetic prostheses, called dental implants.
A very large number of people in the middle age have no teeth. Not a single one. Their best option is a full denture.
Traditional complete dentures are held in the mouth by attaching the plastic base of the denture on the soft tissue. The denture is forming a vacuum with the gums, by the muscle control and thin layer of silva which is underneath. Lower denture has less stable tissue where it should be places, and no large surface of mobile environment. Also, the problem with tongue. It can move the denture with his move. To a large degree the denture keeps its place, because the patient who wears the denture has developed the ability use his tongue as a helper to keeps the denture on place during speaking or chewing.
However, the are a certain number of patients who had never get used to their denture. Many of them do not have enough jaw bone, which is needed for the stabilization of the denture. Some of them simply did not learn how to develop a coordination of the chewing muscles with the denture. Over the years, in dentistry the only thing which was available for complete dentures was adhesive (kind of glue).
In the next developing phase, first alternative that appeared was mini dental implant. The dentists had to insert 4 mini implants exclusively in the lower jaw. The reason why mini dental implants are not recommendable for the upper jaw is because the bone is not solid enough. They started falling out quickly after implementation.
The main goal was to make the lower denture stable, and to make chewing process at least 70% effective in relation to the initial.
From the day the FDA (Food and Drug Administration placed in America) approved mini dental implants placement as a long-term solution for stabilization of the dentures, they become very popular among dentists. We done many of mini implant placement in our clinic during last few years.
From a distance, I could say or write that this kind of an prosthetic procedure did not meet our criteria. The practice shown that there was a high percentage of failure of implants, longevity of mini implants was not great. The patient wants to find a long-term solution for their issues, and in my opinion mini implant placement does not provide it.
Another alternative was the denture that clips over the locator implant attachment. Their durability is better than the mini implants, denture making is not complicated, and can be inserted in the upper jaw. On the other side, the stability of this dentures still is not good enough, and the longevity of implant still is not satisfying.
Dentures over implants
Nowadays, the gold standard of tooth replacement is implementation of 4 dental implants with over denture. The denture is attached to implants over metal bar which spans all inserted implants, and not giving them a place to move. The denture attaches on the implants by clips on that metal bar. Single tooth dental implants, if they are not attached by a metal bone, are not as much durable in the mouth.
Replacement for fully dentures are dentures over implants. Implant-supported dentures are smaller in size, particularly in the upper jaw, when the denture is made without so called palate. Thanks to that, the patient has a better sense during speaking and eating.
This type of palate-less denture are made of metal about one millimeter thick. On the inside it has two clips which clutching onto the metal bar, which is already fixed over the implant. That way the denture is stable in the jaw, doesn’t fallout from the mouth during chewing or speaking, and it is easily removed. This fact is really important because of the hygiene.
The main difference between the denture with locator implant attachment system and the denture over implants is that second type of the dentures are hooked on that metal bar with a larger surface. Because of that they are more stable, and implants lasts longer.
As a result, our patients rebuilt their self-confidence particularly when they are spending their time with friends, because their denture will not fall out from its place during speaking or chewing.
Expectations defined with the terms: lifelong or permanent, are not adequate if we talk about medical or denture practice. There are no guarantee that something will last forever. However, denture over the implant is currently the best option in the long run in the area of dental prosthetics on implants.
Here is one example of the denture over implant, made in our office.
