A dental implant is an artificial replacement for a tooth root. The main aim during the placement of any implant is to achieve immediate close contact with the surrounding bone. Over time further growth of bone onto the implant surface enhances the stability of the implant.
In order to support replacement teeth, dental implants normally have some form of internal screw thread or post space that allows a variety of components to be fitted. Once fitted, these components provide the foundation for long-term support of crowns, bridges or dentures.
Dental implants are suitable for most adults with good general health. Habits such as heavy drinking or smoking can increase the problems associated with initial healing and thereafter may be bad for the long term health of gum and bone surrounding each implant. Some dentists may decline to place implants if smoking cannot be reduced or given up altogether.
