Dental implants are artificial tooth roots inserted into the bone. They serve as a solid base for supporting artificial teeth, called crowns. They are the strongest devices available to support replacement teeth, dentures, or partial denture. First, the metal implant post is placed into the bone. Then, patients need to wait several months for their gums to heal, and their bone to fuse with the implant (osseointegration). Once this process is completed the dentist will attach a component called abutment (the piece where the crown will finally attach). After the abutment is placed, a denture or a bridge can be attached.
