Bone Grafting
Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. Bone loss may make proper placement of dental implants, if not impossible, very difficult. For more detailed info on patterns of bone loss you may refer to the following website by 3i company:

Bone loss 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 would not be candidates for placement of dental implants without proper bone grafting techniques.
We now have the ability to direct the growth of 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 esthetic appearance and functionality.
Distraction osteogenesis
Simply stated, distraction osteogenesis means the slow movement apart (distraction) of two bony segments in a manner such that new bone is allowed to fill in the gap created by the separating bony segments. Activation of the distraction device to slowly separate the bones may cause some patients mild discomfort. In general, the slow movement of bony segments produces discomfort roughly analogous to having braces tightened. For more info you may refer to the following website
Ridge and Extraction Socket Preservation
Careful management of extraction sockets after tooth extraction prevents unsightly bone loss and a better cosmetic outcome of tooth replacement.
Guided Tissue and Bone Regeneration
This surgical procedure "regenerates" the previously lost gum and bone tissue. Most techniques utilize membranes, which are inserted over the bone defects. These membrane work by excluding the ingrowth of connective tisue and epithelium into the treated site. Some of these membranes are bio-absorbable and some require removal. Other regenerative procedures involve the use of bioactive gels.
Sinus Elevation Procedures
In cases of need for dental implants with inadequate bone being present in the back of the upper jaw there is a possibility to place a bone graft in the floor of the maxillary sinus simultaneously or in advance of implants being placed. This can be accomplished under local anesthesia, IV sedation or general anesthesia. There are minimal risks or complications associated with this surgical procedure.
