Replacing
Several Teeth
If
you are missing several teeth, implant-supported bridges can replace
them. Dental implants will replace both your lost natural teeth
and some of the roots.
What
are the advantages of implant-supported bridges over fixed bridges
or removable partial dentures?
Dental
implants provide several advantages over other teeth replacement
options. In addition to looking and functioning like natural teeth,
implant-supported bridges replace teeth without support from adjacent
natural teeth. Other common treatments for the loss of several teeth,
such as fixed bridges or removable partial dentures, are dependent
on support from adjacent teeth.
In
addition, because implant-supported bridges will replace some of
your tooth roots, your bone is better preserved. With a fixed bridge
or removable partial denture, the bone that previously surrounded
the tooth roots begin to resorb (deteriorate). Dental implants integrate
with your jawbone, helping to keep the bone healthy and intact.
In
the long term, implants are esthetic, functional and comfortable.
Gums and bone can recede around a fixed bridge or removable partial
denture, leaving a visible defect. Resorbed bone beneath bridges
or removable partial dentures can lead to a collapsed, unattractive
smile. The cement holding bridges in place can wash out, allowing
bacteria to decay teeth that anchor the bridge. In addition, removable
partial dentures can move around in the mouth and reduce your ability
to eat certain foods.
How
will the implants be placed?
First,
implants, which look like screws or cylinders, are placed into your
jaw. Then, over the next two to six months, the implants and the
bone are allowed to bond together to form anchors. During this time,
a temporary teeth replacement option can be worn over the implant
sites.
Often,
a second step of the procedure is necessary to uncover the implants
and attach extensions. These small metal posts, called abutments,
complete the foundation on which your new teeth will be placed.
Your gums will be allowed to heal for a couple of weeks following
this procedure.
There
are some implant systems (one-stage) that do not require this second
step. These systems use an implant which already has the extension
piece attached. Your periodontist will advise you on which system
is best for you.
Finally,
replacement teeth, or bridges, will be created for you by your dentist
and attached to the abutments. After a short time, you will experience
restored confidence in your smile and your ability to chew and speak.
