Dental Implant

A dental implant is an artificial tooth root — a small titanium screw surgically placed into the jawbone to support a crown, bridge, or denture. Unlike dentures or bridges, implants replace the root of the tooth, not just the visible part above the gum.

Components

A complete implant restoration has three parts:

• Implant fixture: The titanium screw in the bone — the root replacement
• Abutment: The connector piece that emerges through the gum
• Crown (or bridge/denture): The visible tooth or teeth

How it works

After placement, the implant undergoes osseointegration — a biological process in which bone cells grow directly onto and into the titanium surface, creating a permanent, stable bond. This typically takes 8–16 weeks.

How long do they last?

Implant fixtures are designed to be permanent. With good oral hygiene and regular professional maintenance, success rates exceed 95% over 10 years and many implants function for 25+ years. The crown on top may eventually need replacement after 15–20 years.

Who can have implants?

Most healthy adults with adequate bone are suitable. Absolute contraindications are rare. Conditions such as smoking, diabetes, and bisphosphonate medication require individual assessment but rarely rule out treatment completely.
