Simply put, no. A dental implant and a dental crown are not the same thing at all. Crowns can go on natural teeth or dental implants. The crown is the prosthesis we chew on. Seen in this picture are multiple single crowns and a fixed bridge being held.
The dental implant is an anchor placed into the jaw bone to anchor crowns, fixed bridges or dentures. Crowns and dental implants can work together but they are not the same. We do not need one dental implant for each dental crown. Dentists have been placing tooth supported non removable fixed bridges for many decades. A non removable fixed bridge can be supported by two or more dental implants also. An increasing common use for dental implants is as an alternative to tooth supported fixed bridges. Studies done by Carl Misch have documented that a dental implant with a single crown on it is a superior alternative to a tooth supported fixed bridge from a cost and longevity standpoint.
