Bone grafting is building up for the jawbone for the accommodation of a dental implant or a restorative device. Bone grafting is commonly done for dental implants and other periodontal procedures. The bone used to graft is taken from a sample from the patient. Often, it is taken from another area of the mouth when drilling is being done. The bone fragments are suctioned from the mouth and used for the graft. Alternatively, cadaver bone fragments, procured from the bone banks are used which are a very safe source for bone donation.
When you lose teeth and do not undergo restorative surgery, it leads to the deterioration of the jawbone in the area where the tooth socket once was, making it difficult, and sometimes, impossible, to get dental implants or dentures later on when you might be in a better position to afford them. The good news is that we can perform a process called ridge augmentation to restore the bone structure that is needed for restorative procedures such as dental implants. The process involves lifting the gum from the ridge to expose the defected area of the bone. Then the dentist uses a bone like substance to fill the defected areas. The ridge augmentation greatly improves the appearance of the mouth and increases the chances for success with the implants. With ridge augmentation, your implants will last for years.
Loss of posterior teeth could result in excessive pressure on your teeth remnants. While the use of dental implants and crowns allow you to replace these missing teeth, the sinus might be positioned too low in the upper posterior areas to allow proper placement of dental implants.
The repositioning of the sinus floor involves a simple procedure that helps create enough space to properly place an implant. Various grafting materials are used to let your bone to grow more quickly into the area that helps in the stabilization of the dental implant. Replace with your own bone in this area the grafting material as it grows into the area.
Under certain conditions, the option of an even simpler procedure is available. When possible, the bone remaining under the sinus floor is gently “pushed up”, thus lifting the floor of the “dropped” sinus. Bone replacement materials are then placed beneath this lifted bone. Once again the bone materials are replaced as your body grows new bone into this area.
Sinus augmentation procedures are reported to have more than 95% success rate. After sufficient healing of a sinus augmentation (6-10 months), implants are placed in a predictable and successful manner. If the sinus augmentation procedure does not result in enough bone for implant placement the first time, additional bone may be regenerated through a second sinus augmentation procedure at the time of implant placement.
