Dental Implants
Dental implants are changing the way people live! They are designed to provide a foundation for replacement teeth which 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.
What are Dental Implants
The implants themselves are tiny titanium posts which are inserted into the jawbone where teeth are missing. These metal anchors act as tooth root substitutes. They are surgically placed into the jawbone. The bone bonds with the titanium, creating a strong foundation for artificial teeth. Small posts are then attached to the implant which protrude through the gums. These posts provide stable anchors for artificial replacement teeth.
Implants also help preserve facial structure, preventing the bone deterioration that occurs when teeth are missing.
The Surgical Procedure
For most patients, the placement of dental implants involves two surgical procedures. First, implants are placed within your jawbone. For the first three to six months following surgery, the implants are beneath the surface of the gums gradually bonding with the jawbone. You should be able to wear temporary dentures and eat a soft diet during this time. At the same time, your dentist is forming new replacement teeth.
After the implant has bonded to the jawbone, the second phase begins. Dr. Crowley will uncover the implants and attach small posts which will act as anchors for the artificial teeth. These posts protrude through the gums. When the artificial teeth are placed these posts will not be seen. The entire procedure usually takes six to eight months. Most patients experience minimal 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.
We now 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. The bone graft procedures are referred to as sinus lift and ridge-augmentation procedures.
Sinus lift procedure
This procedure involves elevating the sinus membrane and placing the bone graft onto the sinus floor, allowing implants to be placed in the back part of the upper jaw.
Ridge-augmentation
In severe cases the ridge has been reabsorbed and a bone graft is placed to increase the ridge height and/or width.
There are several areas of the body which are suitable for attaining bone grafts. In the maxillofacial region, bone grafts can be taken from inside the mouth, in the area of the chin or third molar region or in the upper jaw behind the last tooth.
These surgeries are performed in the out-office surgical suite under I.V. sedation or general anesthesia. After discharge, bed rest is recommended for one day and limited physical activity for one week.
