Ridge preservation is one of many bone grafting techniques. At times, bone grafting techniques are needed to preserve the ridge of the jawbone after one or more teeth have been extracted. This is because the jawbone shrinks after a tooth has been lost. Unless restorative measures are taken, permanent disfigurement will result.
The procedure will vary to some degree on a case by case basis. In some instances, a ridge preservation procedure can be done at the same time the tooth is extracted. The dentist begins by numbing the entire area to prevent the patient from feeling any pain. If at any point the patient begins to feel uncomfortable, or experiences noticeable pain, the dentist will give him or her additional anesthetic. Sensitive patients may also qualify for sedation dentistry at the dentist’s discretion.
The bone grafting material will then be prepared. Bone could be taken from another part of the patient’s body, or it can be taken from another source. The tooth socket is then rinsed and cleaned to remove all debris and any resident bacteria that could cause infection. At this point, the socket is filled with the grafting material.
In some cases, dentists will place a special membrane over the graft to ensure that the bone and gum tissues heal properly. The socket is closed, usually with only a few stitches.
Ridge preservation offers a number of benefits to patients who have lost teeth. First and foremost, it preserves the shape and strength of the jawbone. This is important for more than one reason. Not only does the integrity of the bone itself need to be preserved, but the contour of the cheeks and lips, which are directly impacted by the shape of the jawbone, must also be preserved.
Secondly, this procedure fills the empty socket left by the missing tooth. Bone tends to grow better when it is in contact with other bone, so this actually helps the existing jaw grow a portion of its original mass back, eventually fusing with the bone graft material.
As a result, the shrinkage that will otherwise result from missing teeth is slowed down significantly. Without tooth roots, the jaw will begin to recede because it will not have the normal vibrations that are normally transmitted through tooth roots during biting and chewing.
Keep in mind, however, that this is not going to stop jawbone recession completely. Bone graft material will provide sufficient surface area for the recession to occur at a slower rate, but the only thing that stops bone recession altogether is a cosmetic dental implant.
Nevertheless, is still a procedure that is worth investing in for the sake of maintaining a healthy appearance and making future tooth replacement options less complicated and more comfortable.

Sometimes you may lose one or more teeth. This can be because the tooth is too far gone to be repaired, and a Houston cosmetic dentist recommends extraction and replacement. It can also be because the tooth is knocked out by some unfortunate accident.
Regardless, a lost tooth is the beginning of complications, not the end. The gap that it creates will then create an indention in your gums and jawbone where the tooth once was.
A Houston cosmetic dentist can correct in this defect with a procedure called ridge augmentation. This will recapture the natural contour of your gums and jaw. A new tooth can then be created that is natural looking, easy-to-clean, and beautiful.
What would cause bone recession in the first place?
It is the nature of the body to reabsorb bone in this fashion. Bone requires vibrational stimulus to signal that brain to send it blood and nutrients for the maintaining and replication of bone cells.
When there is no vibration in a bone, the brain interprets this as a loss of need for the bone, so it reabsorbs the calcium and other minerals that constitute the bone’s makeup and uses these substances for other purposes.
How does this happen in the mouth?
Teeth and bones are intertwined. The roots penetrate into the bone, and the bone grows around the root. When teeth chew food, the vibrations they resonate stimulate the bone and keep it dynamically vibrant. When a tooth is extracted or lost, the bone is reabsorbed into itself.
Without the roots of the tooth to grow around, the jawbone feels it has nothing better to do than to simply withdraw and retreat from the gum line. Over time this indention can actually cause you to lose bone mass. This is not something you want to happen because it can become permanent.
So you see, this is what causes the indentation of the gum. It is both unnatural looking and will often cause a replacement tooth to look too long compared to the adjacent teeth.
What material is used to make this ridge augmentation?
The Houston cosmetic dentist has different options for performing a ridge augmentation. He or she can do use autogenously extracted bone (which means taken from the patient), donor bone, or artificial bone. All of these bone graft materials work, but the autogenously and donor bone works the best.
How do you attach it to the tooth?
Many times when implants are not placed in the extracted site, fixed porcelain bridges will be used to replace the missing teeth. Adjoining teeth are used as abutments to support the new bridge.
Do you have to do anything to the gum tissue?
When a Houston cosmetic dentist does a ridge augmentation, he or she will pump the tissue up to help fill the void. In most instances the tissue is very thin and it covers the bone. Once we increase the bone volume in the edentulous site, it will look like the tissue has filled in.
