Wisdom Tooth Extraction
Before removing a wisdom tooth, your dentist will give you a local anesthetic to numb the area where the tooth will be removed. To remove the wisdom tooth, your dentist will open up the gum tissue over the tooth and take out any bone that is covering the tooth. He or she will separate the tissue connecting the tooth to the bone and then remove the tooth. Sometimes the dentist will cut the tooth into smaller pieces to make it easier to remove.
After the tooth is removed, you may need stitches. Some stitches dissolve over time and some have to be removed after a few days. Your dentist will tell you whether your stitches need to be removed. A folded cotton gauze pad placed over the wound will help stop the bleeding.
A sinus lift is surgery that adds bone to your upper jaw in the area of your molars and premolars. It's sometimes called a sinus augmentation. The bone is added between your jaw and the maxillary sinuses, which are on either side of your nose. To make room for the bone, the sinus membrane has to be moved upward, or "lifted." A sinus lift usually is done by a specialist.
Bone Graft / Augmentation
For dental implants to be successful, the jawbone must have enough bone to support them. If the bone under your gum is not tall enough, not wide enough or both, you will need a procedure to add bone to your jaw before implants can be placed.
These procedures typically involve grafting (adding) bone or bonelike materials to the jaw. The graft can be your own bone or be processed bone (off the shelf) obtained from a cadaver. After grafting, you have to wait several months for the grafted material to fuse with the existing bone. "Off–the-shelf" grafted materials either cause surrounding bone to grow into the graft or cause cells around the graft to change into bone. A graft from your own bone transplants bone cells or a block of bone that fuses to the jaw.
