The best material for a bone graft is your own bone, which most likely will come from your chin, the back part of your lower jaw or your hip bone. The hip is considered to be a better source because the hip bone has a lot of marrow, which contains bone-forming cells. There are also synthetic materials that can be used for bone grafting. To place the removed bone in the recipient site, little holes are drilled in the existing bone to cause bleeding. This is done because blood provides cells that help the bone heal. The block of bone that was removed will be anchored in place with titanium screws. A mixture of the patient's bone marrow and some other bone-graft material will then be placed around the edges of the bone block. Finally, a membrane is placed over the area and the incision closed. The bone graft will take about 6 to 12 months to heal before dental implants can be placed. At that time, the titanium screws used to anchor the bone block in place will be removed before the implant is placed.
Many times there is not enough bone in the jaw to completely cover a dental implant and there is a need to add more bone. In some cases, procedures to widen the bony ridge can be performed with bone grafting techniques called guided bone regeneration. There are now healing accelerators available that are purified human proteins made by cloned bacteria. When added to bone grafting materials, bone may be generated to allow for implant placement.
Periodontal procedures are available to lay the groundwork for restorative and cosmetic dentistry and/or to improve the esthetics of your gum line. Your teeth may actually be the proper lengths, but they are covered with too much gum tissue. Crown lengthening is a procedure to correct this condition.
During this procedure, excess gum and bone tissue is re-shaped to expose more of the natural tooth. This can be done to one tooth, to even your gum line, or to several teeth to expose a natural, broad smile.
Crown lengthening can make a restorative or cosmetic dental procedure possible. Perhaps your tooth is decayed, broken below the gum line, or has insufficient tooth structure for a restoration, such as a crown or bridge. Crown lengthening adjusts the gum and bone level to expose more of the tooth so it can be restored.
Impacted canines may be retrieved with braces, using a surgical approach via a gold chain or straight wire. Tissue covering the tooth is uncovered. A chain or wire is attached to the tooth crown. Tissue is placed back over the tooth leaving the chain or wire coming out of the gum. For the purpose of this illustration a gold chain is used to retrieve the canines. The chain is attached to the tooth crown and the link is attached to a flexible archwire so that the wire is active (bent). Once a month, the wire is reactivated by using the next link up on the chain until the impacted canine erupts enough to attach a regular bracket on the canine. With the regular bracket in place, a more flexible wire is added directly to the bracketed canine. This process will bring the canine into position within the arch by forcing the canine to conform to the straight archwire form. This is a long process taking anywhere from 8-12 months.
