A bone graft is a surgical procedure that replaces missing bone with material from the patient’s own body or an artificial, synthetic, or natural substitute. The graft not only replaces missing bone, but also helps your body to regenerate its own bone. This new bone growth strengthens the grafted area by forming a bridge between your existing bone and the graft material. This bone loss can be reversed. Over time your own newly formed bone will replace much of the grafted material.
Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants.
We now have the ability to grow bone where needed. This gives us the opportunity to place implants of proper length and width, and it also gives us a chance to more effectively restore aesthetic appearance and functionality.
When you lose teeth, and do not replace them, the jawbone deteriorates where the tooth socket once was. This makes it difficult, and in some instances impossible to get dental implants or dentures later on. You may have not had the financial means at the time of the extraction for restorative surgery, but you may have the money now. 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 may result in excessive forces being placed on your remaining teeth.Fortunately, the use of dental implants and crowns allow you to replace these missing teeth. However, the position of the sinus in the upper posterior areas may be too low for proper placement of dental implants.
A simple procedure allows the sinus floor to be re-positioned, creating enough space to properly place an implant. Various grafting materials are used to encourage your bone to grow more quickly into the area, helping to stabilize the dental implant. Replace with your own bone in this area the grafting material as it grows into the area.
Under certain conditions, an even simpler procedure can be utilized. 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 grow new bone into this area.
Sinus augmentation procedures are highly predictable, with studies reporting over 95% success. Following sufficient healing of a sinus augmentation (6-10 months), implants are placed in a predictable and successful manner. It is important to realize that if the sinus augmentation procedure does not result in enough bone for implant placement, additional bone may be regenerated through a second sinus augmentation procedure at the time of implant placement.
