Dental Bone Grafting
Dental procedures are quite intricate and challenging to perform. At times dentists and oral surgeons advise patients to get dental bone grafting to maximize the results of dental surgeries. For any dental implant to be successful, there should be enough bone in the jawbone to support the implants. There can be a loss of bone over time, which can be caused due to various reasons such as an injury or trauma, missing teeth,gum disease, infection, cavities or defective bone development.
One needs a procedure to add bone before placing the implants, in case the bone under gums is not tall or wide enough or if the tooth loss is severe. Every dental procedure sounds painful, but bone grafting is a pretty common dentistry practice, and the good part is that that it is a painless procedure.
What is Dental Bone Grafting?
This procedure ‘builds’ bone in the jaw to support dental implants. In other words, it can be said as a bone regeneration process. Grafts can be done from the patients’ bone or it can be a processed/off the shelf bone that is obtained from cadaver. The decision of which should be used is based on the location, type and the number of implants that are required.It takes several months for the grafted bone to fuse with the existing bone.
Processed bone causes the graft to change into bone or causes the bone to grow into the graft. This periodontal regenerative surgery helps in the regrowth of lost tissues and give better results of dental surgeries. Dentists wait around four to nine months after grafting to proceed with placing the implants.
How Do Dentists Prepare for Bone Grafting?
Before starting with bone grafting, dentists perform a procedure called as scaling to clean the teeth and gums. Once that is done, periodontal defects are examined and accordingly root planning is done.When one is ready for the surgery, local anesthesia is given to numb the area. This way patients will not experience any kind of tooth pain or hurting gums during the surgery.
Then the dental surgeon separates gums from the teeth. This allows them to gain access to the bone and roots under the gum. The roots are cleaned thoroughly and all the ‘missing’ bone or holes in the bones are identified. They are filled with the graft material and then it’s covered with a physical barrier to promote healing. These barriers, made from human skin to synthetic materials, prevent the gums from growing into the bony defect. They also prevent infections of any kind.
After the graft is put, the gums are put back over the treated site and is stitched into place. Special dressing or bandage may be used over the denture if necessary. It takes around six to nine months for the new bone to fill the empty space. Connective tissue regeneration and soft tissue regeneration can also be observed during this phase.
Why Bone Grafting?
The importance of bone grafting cannot be questioned for carrying out several dental procedures such as implants or crown lengthening. At the same time, it is done to maintain or restore facial structure. Some dental implants require the bone to be close to the original position and dimension for better results. Moreover, the jaw and adjoining facial bones support skin and muscles which are responsible for outward appearance. If the underlying bone is missing, there is a tendency to look premature or aged. Thus, bone grafting helps in increasing the aesthetic appeal too in addition to promising great dental results.
