Implants can also be used in conjunction with dentures to reduce
movement of dentures and facilitate chewing.--When a tooth is
lost the specialized bony process that houses the tooth begins
to resorb due to lack of stimulation. This causes a decrease
in width and height of the bone in the area the tooth is lost.
Neighboring teeth and opposing teeth begin to move into the
space. This causes food lodgment, subsequent decay, gum disease
and abnormal forces being transmitted to teeth leading to fracture
of cusps which may necessitate root canal treatment or extraction.
Loss of teeth can also cause the cheek and lips to collapse
giving an aged look.
The
consequences of tooth loss can be prevented by replacing the
lost tooth in a timely manner. Although there are several options
to replace a missing tooth the number one choice for replacing
lost teeth are dental implants. Implants are tiny titanium screws
or posts that are surgically placed in the bone. Once integrated
into bone they act like roots onto which small posts are attached
which protrude through the gums. These posts provide stable
anchors to the replacement teeth. Implants maintain the bone
height by stimulation and prevents unnecessary trimming of adjoining
teeth for bridge placement. Since implants are titanium posts
there is no chance for decay on implants. Implants can service
you for several years with regular professional cleaning and
proper home care.
Many
people who are missing a single tooth opt for a fixed bridge;
but a bridge may require the cutting down of healthy, adjacent
teeth that may or may not need to be restored in the future.
Then there is the additional cost of possibly having to replace
the bridge once, twice or more over the course of a lifetime
due to decay or gum problems affecting the anchor teeth.
Another
option to replace missing teeth is a removable partial denture
or complete denture depending on the number of teeth missing.
The chewing efficiency with a denture is reduced to more than
half of that of natural teeth. The teeth that support the partial
denture are weakened due to the excessive loads acting on them
and eventually are lost. The denture rests on the gum causing
tissue abrasion and bone loss. Removable dentures may slip or
cause embarrassing clicking sounds while eating or speaking.
Studies
show that within five to seven years there is a failure rate
of up to 30% in teeth located next to a fixed bridge or removable
partial denture.
Who
is a candidate for Implants?
Anyone
who is missing one or several teeth is a candidate for implants.
With the exception of growing children, dental implants are
the solution of choice for people of all ages, even those
with the following health concerns:
Existing
Medical Conditions: If you can have routine dental
treatment, you can generally have an implant placed. While
precautions are advisable for certain conditions, patients
with such chronic diseases as high blood pressure and diabetes
are usually successful candidates for dental implant treatment.
Gum
Disease or Problem Teeth: Almost all implants placed
in patients who have lost their teeth to periodontal disease
or decay has been successful.
Currently
Wearing Partials or Dentures: Implants can replace
removable bridges or dentures, or they can be used to stabilize
and secure the denture, making it much more comfortable.
Smokers: Although smoking lowers the success rate of implants,
it doesn't eliminate the possibility of getting them.
Bone
Loss: Bone loss is not uncommon for people who have
lost teeth or had periodontal disease. Oral and maxillofacial
surgeons are trained and experienced in grafting bone to safely
and permanently secure the implant.
Implant
tooth replacement in children is usually deferred until their
jaw growth is complete. There are, however, some instances
when a dental implant may be appropriate, such as when it
is part of the child's orthodontic treatment plan. Your family
dentist or orthodontist can guide you in this instance.
Procedure
Dental
Implant placement usually takes two surgical appointments:
1. During the first surgical appointment the implant site
is prepared to receive the implant following strict aseptic
procedures. The selected size of the implant is placed in
the prepared site. The gum tissue is sutured over the implant.
The implant takes 4- 6 months to fuse with the bone.
2. During the second surgical appointment the implant is uncovered
and the appropriate post is attached to which the replacement
tooth is anchored. An impression of the post is taken and
sent to the lab for the fabrication of the implant crown.
During this time a temporary crown is placed. Once the final
crown is back it is cemented with permanent cement. |
