Implants
What is an implant?
An
implant is a metal blade or post which is surgically inserted into the jawbone. Some older implants were made of steel, but implants in current use are made of titanium with various surface coatings for different applications. Researchers are also looking at some ceramics as an alternative. The titanium insert is biological stable, and is considered to be osteogenic, in that it encourages new bone formation. The bone grows right onto the implant, forming a solid structure. We can then subsequently place single crowns, bridgework, or attachments to retain
dentures on top of the implants. This enables us to restore the form, function and aesthetics of the mouth, enabling the recipient to eat and smile with confidence. The placement of implants helps to prevent the loss of jawbone which naturally occurs with loss of the teeth. As such it helps maintain the strength and shape of the jaws, and contributes to maintaining a youthful appearance. Implants can be placed in almost anyone over 16. They are not normally used in children, as their bones are not fully grown. Current success rates with implants are over 90%.
Contra-indications
Smoking is the biggest contra-indication for implants, as it seriously affects the bone chemistry, preventing the normal uptake of calcium. It also affects wound healing and depletes
VitaminC which is also essential for healing. Smoking reduces the success rate to under 60%.
Alcoholism also affects bone health, and there are other factors to consider. Alcoholics are often less than fastidious about their general health and hygiene, and are therefore unlikely to be good candidates for implant treatment.
Diabetes when uncontrolled can seriously affect the healing processes, however, well controlled diabetics can be considered for treatment. Other
