Implants are artificial substitutes that replace missing teeth, including the root. They are implanted in the jaw bones in place of missing teeth. After a healing period of about 3 to 6 months, the titanium implants will be part of the jaw bone to provide solid support to the artificial teeth. Implants are an excellent alternative to dentures, crowns and bridges. They are not dependent on other natural teeth for support. The treatment usually takes longer and involves minor surgery.
