Quick answer
For a single missing tooth, an implant commonly supports a crown through an abutment. For several or all missing teeth, implants may instead support a bridge or full-arch prosthesis. The treating dentist determines the appropriate restoration.
The implant is below the gum
The implant fixture is surgically placed in the jaw and functions as the foundation for the replacement tooth. It is not the white tooth you see when you smile.
The crown is the visible tooth
A crown is made to reproduce the visible portion of a tooth. In an implant restoration it attaches to an abutment connected to the implant. Crown material and design are selected as part of the prosthetic plan.
Several implants can support several teeth
If multiple teeth are missing, a dentist may recommend an implant-supported bridge rather than one implant for every tooth. Full-arch cases may use a larger prosthesis supported by several implants.
Why this matters when looking at prices
If an advertisement says “implant from…” check whether the crown and abutment are included. A low implant fixture price may not represent the total price for a completed replacement tooth.
Ask for the final-restoration plan
Before proceeding, ask what restoration you will leave with at each stage: temporary tooth, temporary bridge, healing component, final crown or final full-arch prosthesis. That makes both timing and costs much easier to understand.
