Major & Minor Bone Grafting
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. Today, we have the ability to add bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and aesthetic appearance.
Major Bone Grafting
Bone grafting can repair dental implant sites with inadequate bone structure due to previous extractions, gum disease or facial injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw or hip. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration. Bone grafting is sometimes done at the time of tooth removal with Socket Preservation or BioColl Graft. This is done with cadaver (human donor) bone. This graft helps ensure the width of the remaining socket while the bone is healing to be best suited for implant placement. This graft does not add vertical height. This graft takes four months to heal and then the area is evaluated with a Galileos 3D CT scan to assess placement of dental implant(s).

If an area or areas have been allowed to heal for a long while after tooth removal, most often we get atrophy or loss of bone both vertically and horizontally that prevent placement of implants without grafting. This type of graft often requires bone from you (autogenous) be taken from the lateral jaw or chin and grafted. This graft takes 4 months to heal and then a Galileos 3D CT scan is taken to assess placement of dental implant(s). Major bone grafts are typically performed to repair large defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patients own bone. This bone is usually harvested from the hip (iliac crest). These procedures are routinely performed in an operating room and require a hospital stay.
Sinus Lift Procedure
The maxillary sinuses are behind your cheeks and on top of the upper teeth. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth. The floor of the maxillary sinus is the roof of the upper jaw. Dental implants need bone to hold them in place. When the sinus floor or roof of the upper jaw is very thin, it is impossible to place dental implants in this bone. Sinus expansion after extractions. There is a solution and its called a sinus graft or sinus lift graft. The sinus area is entered from where the upper teeth used to be. The sinus membrane is then lifted upward and donor bone is inserted into the floor of the sinus. After (9-12) months of healing, the bone becomes part of the patients jaw and dental implants can be inserted and stabilized in this new sinus bone. Refer to Consult Pro Videos for more information (After clicking the link click on Tab “Implant 2 ” then “Sinus Grafting Procedure”). The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option other than wearing loose dentures. If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the dental implant well, sinus augmentation and dental implant placement can sometimes be performed as a single procedure. If not enough bone is available, the sinus augmentation will have to be performed first, then the bone graft will have to mature for 9-12 months. Once the bone graft has matured, the dental implants can be placed. Dental implants usually take 4 months to heal. Refer to Consult Pro Videos for more information (after clicking the link go to Tab “Implant 2”).
In severe cases, the ridge has been reabsorbed and a bone graft is placed to increase ridge height and/or width. This is a technique used to restore the lost bone dimension when the jaw ridge gets too thin to place conventional dental implants. In this procedure, the bony ridge of the jaw is literally expanded by mechanical means. Bone graft material can be placed and matured for a few months before placing the dental implant. These procedures may be performed separately or together, depending upon the individual’s condition. As stated earlier, there are several areas of the body that are suitable for attaining bone grafts. In the maxillofacial region, bone grafts can be taken from the back of the lower jaw, chin area, or back of upper jaw. These are all harvested from inside the mouth. In more extensive situations, a greater quantity of bone can be attained from the hip. When we use the patients own bone for repairs, we generally get the best results. In many cases, we can use allograft material to supplement bone grafting for dental implants. This bone is prepared from cadavers (human donor) and used to promote the patients own bone to grow into the repair site. It is quite effective and very safe. Synthetic biomaterials (Mitogens or bone morphogenic protein-BMP2) can also be used to help stimulate bone formation and growth.Dental ImplantsDental ImplantsFacial TraumaDental ImplantsDental ImplantsDental ImplantsGalileos 3D ImagingDental ImplantsDental ImplantsDental ImplantsDental ImplantsDental ImplantsDental ImplantsDental ImplantsGalileos 3D ImagingDental ImplantsFacial TraumaDental ImplantsGalileos 3D Imaging
