Most dental implants are small titanium cylinders which are embedded in
the patient's jaw bone to act like the root of a tooth. Different types
of dental prostheses can be attached to the implants to replace missing
teeth. Since the implant is fused directly to the bone, these replacements
are as solid as the original teeth. The above drawing, done by Wayne
Heim, shows an implant and how the implant can be placed in the jaw.
Below are some examples of how implants can be used to replace missing
Fixed / removable dentures (Hybrid dentures)
Hybrid dentures are a way to replace teeth when all or most of
the teeth are missing on the upper or lower. They are especially useful
when a lot of bone is lost and patient is having a difficult time wearing
a denture. The prostheses consists of a metal frame screwed onto the implants
with teeth and pink plastic added to simulate the teeth and gums. The appliance
can readily be removed by the dentist by loosening the screws. This is only
needed occasionally for maintanence and sometimes for more thorough professional
