Dental implants are metal frames which are surgically positioned into the jawbone beneath the gums. Once they are well positioned, they allow the dentist to mount replacement teeth onto them. Implants provide a stable support for any artificial tooth replacement. The bridges and dentures mounted to implants will not shift or slip in your mount especially when eating or speaking.
Some people do not prefer ordinary dentures and bridges because they are not comfortable because of sore spots, gagging or poor ridges. With implants, there is no adjacent teeth need to be prepared to hold the new replacement teeth in place. The followings are the most common types of dental implants.
Root-form implants are the most common type of Implant available. They are also referred to as endosteal implants because they are replaced in the bone. They either take the shape of thick nail, screws or cones or come in different lengths and widths. However, for these types of implants to be successful, the bone should be deep and wide enough to provide a secure foundation. The type of your bone is what dictates the type of implant to use. Root-form implants can be inserted in two ways.
In the single stage procedure, the implant is inserted into the bone and remains exposed in the mouth. While in the second stage, the implant is buried under the gum tissue and then exposed during surgical procedures.
Ramus-frame implant can be the best alternative to root-form implant or subperiosteal implant, especially if your jawbone is very thin. A Ramus-frame implant is embedded in the jawbone in the back corners of the mouth and near the chin. After it has been successfully inserted and the tissue has healed, a thin metal bar is visible around the top of the gum. Dentures are designed in a manner that it fits into this bar.
These implants also stabilize weak jaws and prevent any fracture that may occur.
Primarily, these implants were designed to be used by those individuals who had little bone on their lower jaws or had no bottom teeth. Lately, they are not commonly used because they require extensive surgery, hospitalization and anesthesia when placing them. In addition, their use is limited to the lower jaw. Placing them involves inserting two metal rods from below the chin until they are exposed inside your mouth. Those rods seen inside the mouth are used to attach the debantures.
Most dentists prefer bone grafts to transosseous methods since they are equally effective and no surgery required when placing transosseous implants.
Blade-form implant can as well be referred to as a plate-form implant. It is another form of endosseous implant, but is not used so often like a root-form implant. These are flat metal rectangles with at least two metal prongs on one long side. Blade implants are placed in the jaw so that the prongs which stick out into the mouth support bridges or crowns.
Most dental implants are actually made of titanium. This is because this metal has some special and unique qualities which make it so useful for this purpose. One of these qualities is that titanium develops a thin film on its surface protecting it from any form of corrosion. Furthermore, it is resistant to oxygen, salt among many other things which can cause corrosion.
Titanium metal is extremely strong for its weight and is totally non-magnetic. Moreover, the body system does not recognize titanium implants as foreign objects. This implies that they are easily compatible with the body system. Once an implant is placed in the bone, the bone grows uninterrupted around the implant through the process called osseointegration.
In addition, titanium implants come with various types of surfaces which include plasma sprayed, acid etched and grit blasted, hydroxyapatite coated and acid etched. It is also important to note that Hydroxyapatite is a part of what the bone is made from. This means that it will bond easily with the bone through the process called biointegratio
These are some of the types of dental implants available. They all have different requirements and therefore, it is very important to consult your dentist on which one best suits you depending on your bone type among other factors. Some of them could be really expensive while others could be relatively cheaper. So, it all depends on your budget.
