| Dental Implant
or Tooth Implant is an artificial tooth root replacement and is
used in implant-supported
dental crowns,
dental bridges
and dentures. |
| |
|
 |
 |
| |
| There are several
types of tooth implants. The most commonly accepted and successful is
the titanium implant.
Process is based on the discovery by Swedish scientist Per-Ingvar
Branemark (Brånemark) of a structural and functional connection between
the jaw bone and the dental implant (osteointegration). There are over 100
companies available on the U.S. market: Nobel Biocare, Straumann, 3i, Zimmer,
BioHorizons, Astra Tech, Ankylos, Implant Direct, Lifecore, and Bio-Lok
and many others.
A typical implant consists of a titanium screw, with a
roughened surface. At edentulous (without teeth) upper or lower jaw
sites, the dental implant is screwed into the surrounding bone.Once in the bone, a cover implant screw is placed and
the operation site is allowed to heal for a few months for integration
to happen.
After some months the implant is uncovered and a healing abutment
(temporary crown) is placed onto the implant. This encourages the gum to
grow in the right shape. |
| |
| Finally the
permanent dental crowns,
dental bridges
or dentures
(over-denture) will be constructed and placed on the implants. |

Exclusive Procedures
|
| Bone replacement
(auto transplantation), a bone graft procedure (a block graft) and sinus
lifting (sinus augmentation) are the common surgical practices at the
present time. Jaw bones have to be strong enough to hold and support the
implant. The placement of a
dental implant into a recent
tooth extraction site could also
preserve the bone and reduce treatment times.
Success
Rates
At the present time
5 year success rate of implants is between 75-95% and related to:
- Quality and quantity of the
jaw bones at the implant place
- The patient's oral hygiene
- Who smoke experience
significantly poorer accomplishment rates
Failure
A dental implant is
considered to be a failure if it is lost, mobile or shows the bone loss
around. It is usually related to break down of the osseointegration
(connection to the jaw bone).Risk of failure is
increased in smokers. The implants are commonly placed only after a
patient has stopped smoking as the treatment is very expensive.
An implant also may
not succeed because of poor positioning at the time of surgery, or may
be overloaded. |
Contraindications
|
- Uncontrolled type II
diabetes is a significant relative contraindication. Healing
following any type of surgical procedure is delayed due to poor
peripheral blood circulation.
|
- The little volume and
height of the jaw bone available.
|
- Bruxism (tooth clenching or
grinding) is a threat to implants while bone is healing and
throughout the life of the recipient. This problem can be minimized
by wearing a custom made mouth-guard at night (night-guard).

Dental Implants Maintenance
|
| Tooth implants are
like your own teeth and will require the thorough at-home
oral care
and regular dental visits to make sure they are healthy.
YOUR IMPLANTS CAN SERVE YOU FOR YEARS IF YOU KEEP YOUR MOUTH HEALTHY! A crowned dental
implant is protected from
tooth decay
but do not protected from gum disease! |

Waterpik Ultra Dental Water Jet (WP-100W)
is a
NEW!,

device and very effective
oral care tool for those that can't or won't use
dental floss. |

You should
continue performing a great oral hygiene! |
