After tooth extraction, the tooth socket will usually fill naturally with bone in two to three months. However, without bone grafting the height and width of the bony socket will decrease. This loss of bone ridge volume after tooth extraction can be quite dramatic, with up to 50% of the volume lost within six months. Bone graft is most often placed at the time of tooth extraction to help your body fill in the empty socket with bone, in a procedure known as socket preservation. This will maintain the width and volume of bone you will need for implant placement.
Bruxism is an oral parafunctional activity that commonly occurs in most people at some point in their lives. The two main characteristics of this condition are grinding of the teeth or clenching of the jaw. These actions usually occur during a person’s sleeping hours, but may also occur during the day, particularly when stressed. Bruxism is one of the most common known sleep disorders. The most common symptoms are earaches, headaches, muscle pain and tooth discomfort, but can lead to difficulty in eating or opening and closing your mouth.
The maxillary sinuses are behind your cheeks and on top of the upper teeth. These sinuses are empty, air-filled spaces. 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.
