Socket Preservation, Ridge Augmentation, Sinus Lift/Augmentation

Bone graft for dental implant is a surgical procedure that replaces missing bone. Procedure is extremely complex, poses a significant health risk to the patient. Autogenous bone graft is the preferred technique as there is less risk of the graft rejection because the graft originated from the patient’s own body.  Dr. Navid Rahmani is an internationally recognized, Board Certified Periodontist and Dental Implant Specialist. All procedures are performed in our NYC Dental Implants Center

Depending on the site of the bone loss and your individual needs, Dr. Rahmani, a top implant dentist in New York will use one of several different techniques to help replace the missing bone.

Socket Preservation

When it is necessary to remove a tooth, it is possible that the socket that used to hold the tooth will have become damaged by disease or infection. Additionally, tooth removal can result in changes to the surrounding bone and gums.

Bone loss and gum recession can occur very soon after extraction, creating substantial problems for subsequent restorative dental implant procedures in NYC.

Socket preservation technique that can help enhance the appearance of your new dental implant and which will improve your chances of enjoying successful dental implant treatment for many years to come.

One popular socket preservation technique is to fill the empty socket with bone grafting material or artificial bone grafting material. Afterwards the bone grafting material may be covered up with an artificial membrane containing special proteins to help stimulate your body to repair the empty socket and to prevent the gum tissue from growing into the bone. The artificial membrane is then covered up with gum to protect it.

Strong and Stable Foundation for a Dental Implant

This method can be enormously successful helping to eliminate the shrinkage and collapse of bone and gum tissue, and the newly formed bone in the empty socket provides a strong and stable foundation for a dental implant.

Socket preservation can be particularly useful when replacing front teeth with either dental implants or mini dental implants (small diameter implants).


Ridge Augmentation

bone grafting ridge augmentationA ridge augmentation is another common procedure carried out following tooth extraction. It helps to recreate the natural contour of the jaw and the gums that may have been lost due to bone resorption.

When a tooth root is removed it leaves an empty socket in the alveolar ridge, which is the raised ridge of bone that supports your teeth. Alveolar bone is a thickened ridge of bone that helps to protect the tooth sockets.

After tooth removal, the empty socket will usually heal well on its own, gradually filling up with bone and gum tissue, but sometimes when a tooth is removed the alveolar bone surrounding the empty socket will begin to break down, causing loss of height and width in the alveolar ridge.

Purpose of a Ridge Augmentation

The purpose of a ridge augmentation is to rebuild the ridge to its original height and width.

This makes sure that dental implants will have plenty of bone to support them and it also helps to ensure good aesthetics once the implants have been restored with replacement teeth.

It is possible to carry out a ridge augmentation at the same time natural teeth are removed by placing bone grafting material into the empty socket. Another option is to have the ridge augmentation carried out at a later date.

Time to Heal

Generally this type of bone graft will need to heal for between four to 6 months before dental implant placement although occasionally it might be possible to place the implant at the same time as the ridge augmentation. Sometimes Dr. Rahmani will also suggest a soft tissue ridge augmentation. By replacing any lost gum tissue, we can ensure that the alveolar ridge has the correct contours so the final implant restoration will look aesthetically pleasing.

Sinus Lift/Augmentation

bone grafting sinus lift augmentationSinus lift procedure is very common when using dental implants to replace upper back teeth.

The maxillary sinuses are located just above your upper jaw, either side of your nose and are empty, air filled spaces.

It is possible for a natural tooth roots to extend up into these maxillary sinuses and often after they are removed there will only be a very thin wall of bone remaining in between the sinuses and the mouth. This is not sufficient to support dental implants, which is why you may need a sinus lift or graft.

This helps to strengthen and build up the bone in the area around your sinuses, ensuring dental implant treatment will be a success.

Sinus Lift Procedure

To do this procedure, Dr. Rahmani will need to make an incision in your gums to expose the jawbone directly underneath your sinuses. A small opening is then cut into the bone, exposing the membrane in between your sinuses and your jawbone.

The membrane is gently lifted or pushed upwards, creating a space in between the membrane and your jawbone which can then be filled with bone grafting material. Once the bone graft is in position, the incision in your gums will be stitched up and the healing process begins.

Sometimes it is possible to carry out a sinus augmentation while placing your dental implant, but if a substantial amount of bone is needed then it may be better carried out as a separate procedure and the bone graft will need to heal for several months before your implant can be inserted.
