Dental Implants - Implant Examination
How Will I Know if I Have Enough Bone for Implants?
By using a combination of dental x-rays and physical examination, your bone density and volume can be assessed, and information about nearby anatomical structures to avoid (such as nerves) can also be gathered.
The alternatives for replacing missing teeth include dentures and bridges. However, there are various bone-grafting and tissue-regeneration procedures that can be carried out to enable treatment with dental implants.
Sinus Augmentation - if you need to replace missing teeth at the back of the upper jaw, a sinus augmentation, whereby new bone in the sinus is created, can increase the height of the bone available for the placement of implants in this area.
Onlay Grafting - this is where a piece of bone is taken from somewhere else and secured over an area that is deficient on bone: over time, the newly placed bone will fuse with the underlying bone creating a better environment for an implant to be placed.
The best source of bone for your graft is your own bone tissue from elsewhere in the body. Bone can be grafted from the chin, the back of the lower jaw, the hip and the tibia. Bone taken from your own body is the most viable and has faster healing times when compared to alternatives.
In many cases, a combination of artificial bone substitutes and your natural bone is used. In any bone grafting procedure, the grafted bone provides an anchor and stimulus for the existing bone to grow onto, eventually providing an environment suitable for the placement of implants.
