Ridge Augmentation (Block Graft)
What is a bone graft?
Bone grafting augmentation is a term that is used to describe a variety of procedures that are used to "build" bone so that dental implants can be placed. These procedures typically involve grafting (adding) bone or bonelike materials to the jaw, and waiting for the grafted material to fuse with the existing bone over several months. There are several different procedures that can be used for bone augmentation. Selecting a procedure depends on the type, location and number of implants to be used. If you need a bone graft, it is important that you understand all of the options available to you. After a bone-augmentation procedure, Dr. Alvarez usually waits 4 to 12 months before placing implants.
Why is a bone graft needed?
Bone grafting is performed to reverse the bone loss / destruction caused by tooth loss, periodontal disease, trauma, or ill fitting removable dentures. This procedure is also needed for augmenting bone in the sinus area for implant placement, or augmenting bone to enhance the fit and comfort of removable prosthesis, or to enhance esthetics of a missing tooth site in the smile zone. When one loses a tooth, as in an extraction, the surrounding bone collapses. To preserve this bone for future implant placement or for esthetics, a bone graft is used.
Sinus Lift (Bone Graft)
A sinus-lift procedure is performed to augment bone mass in the top jaw (maxilla) when lack of bone structure is found between the posterior maxillary ridge and the floor of the sinus chamber, which increases the likelihood of successful placement of dental implants. Bone from another surgical area, donated bone tissue, or artificial bone grafting material is grafted into the bone (endosseous) below the floor of the maxillary sinus. This is a very predictable procedure that Dr. Alvarez has successfully performed for many years.
