Bone grafting is a procedure that is aiming to built up the jawbones to accommodate a dental implant or to restore them to more natural shape. Bone grafting is used frequently for dental implants and other periodontal procedures (guided tissue regeneration). The bone used to graph can be taken from the patient, from different areas of the mouth. Commercialized bone fragments are also used. They are harvested by bone banks and are a very safe source for bone donation.
When you lose teeth, and do not replace them, the jawbone change, is receding or deforming. This makes it difficult, and in some cases impossible to get dental implants or dentures later on.In our office we can perform a surgical procedure called ridge augmentation that will restore the bone structure that is needed. The process involves local anesthesia and exposing the defected area of the bone. Then the dentist uses a bone like material to fill the defected areas. The ridge augmentation greatly improves the chances for success with the implants. With ridge augmentation, your implants will last for years.
Loss of your teeth may result in excessive forces being placed on the remaining ones and in increased size of the maxillary sinuses. Nowadays, the use of dental implants and crowns is a standard treatment for replacing these missing teeth. However, the position of the sinus floor in the upper posterior areas may be too low and will not be enough bone for proper implant placement
Sinus lift is a simple procedure that allows the sinus floor to be re-positioned, creating enough space for the future implant. Various grafting materials can be used and act as a scaffold. The grafting material is replaced by your own bone as it grows into the area and there will be enough bone to stabilize the implant.
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.
