The replacement of hopeless or lost teeth using dental implants has been a revolution in dentistry. Our office has been a leader in these techniques. Thorough planning and precise placement are essential for success. Your treatment is individually tailored to your needs. The details of your care will be discussed and clearly outlined.
Dental implants are designed to provide a foundation for replacement teeth that look, feel, and function like natural teeth. The person who has lost teeth regains the ability to eat virtually anything and can smile with confidence, knowing that teeth appear natural and that facial contours will be preserved.
The implants themselves are tiny titanium posts that are placed into the jawbone where teeth are missing. The bone bonds with the titanium, creating a strong foundation for artificial teeth.
In addition, implants can help preserve facial structure, preventing the bone deterioration that occurs when teeth are missing.
Dental implants are changing the way people live! With them, people are rediscovering the comfort and confidence to eat, speak, laugh and enjoy life.
Dr. Felthousen has received extensive training in the use of dental implants to replace missing teeth. He was the first periodontal resident to place implants at the University of Maryland in 1989. He has continued to be a leader and teacher of these procedures in our area.
Dr. Felthousen was recently trained in the use of computer guided implant surgery. Our office is one of the first one hundred in the world to be trained in these techniques. The I-Cat Facial CT scanner is now a part of our office equipment. It is the only, in office, CT scanner in the area. This machine allows us to plan and utilize the latest implant techniques. These include immediate implants, “Teeth in a Day” and “Teeth in an Hour.”
After the implant has bonded to the jawbone, the second phase begins. Your general dentist will be able to start making your new teeth. An impression must be taken. Then posts or attachments can be connected to the implants. The teeth replacements are then made over the posts or attachments. Most patients do not experience any disruption in their daily life.
Bone grafting
Major and 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. In these situations, most patients are not candidates for placement of dental implants.
Today, we have the ability to grow 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 esthetic appearance.
Major Bone Grafting
Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip or tibia (below the knee.) 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 or guided tissue regeneration.
Major bone grafts are typically performed to repair 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 patient’s own bone. This bone is harvested from a number of different sites depending on the size of he defect. The skull (cranium), hip (iliac crest), and lateral knee (tibia), are common donor sites. 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. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.
There is a solution and it’s called a sinus graft or sinus lift graft. The dental implant surgeon enters the sinus 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. Keep in mind that the floor of the sinus is the roof of the upper jaw. After several months of healing, the bone becomes part of the patient’s jaw and dental implants can be inserted and stabilized in this new sinus bone.
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 implant well, sinus augmentations and 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 graft will have to mature for several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.
