Dentoalveolar surgery is the very important aspect of Oral and Maxillofacial Surgery that concentrates on routine issues such as extractions, bone contouring, surgical root canals and minor soft tissue repairs. It actually represents nearly 50% of all minor surgeries completed in our dental clinic Vyhlidka. Anyone who has ever experienced a toothache will appreciate the importance of every day dentoalveolar surgery.
Teeth may need to be removed for a number of reasons. This could include orthodontic considerations or as a result of extensive decay, disease, or trauma resulting in painful, abscessed, or loose teeth. In most non-emergency situations involving the need for dental extractions, we will evaluate and treat you at the same visit. This treatment can be performed under local anesthesia (numbing medicine), conscious sedation or general anesthesia. On many occasions a special Panoramic X-ray will be needed to identify vital structures in the area of the surgery.
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 aesthetic appearance.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). Often a block of bone may be taken from a donor site in the jaw and "transferred" to a recipient site to augment a jaw area prior to placing a dental implant. A new technique involves utilizing recombinant BMP (Bone morphogenic protein) to grow bone in a deficient site.
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.
