This video shows the tooth implant procedure used in the extraction and replacement of a single tooth. The dentist explains this with the help of a patient who suffers from a dead tooth which necessitated the replacement with an implant.
The dentist obviously uses the video as an advertisement but in the process shows how the implant is actually inserted into the empty socket. He screws it tight to allow it to get set. After a week the patient is back with a healthy implant in place which is now ready for a crown.
