インプラントは実際人工歯根の役割を果たす。インプラントは安定した基礎を提供するために骨の中に固定されその後、人工歯が強固に装着される。インプラントを使うことによって、隣の天然歯は削られる必要がないので、ダメージを受けることはない。 |
|
インプラントは隣在歯の移動を防ぐので、健康的な噛み合わせも保存できる。そして寿命が短くかつしばしば数年後に作り直さなければいけないブリッジと違って、インプラントは大体永久的で、そして問題が少ない。 |
| どの歯にインプラントができるのか |
 |
１本の歯
１本の欠損歯によるスペースをなくすために、１本のインプラントを入れる方法が最も自然で長持ちする。インプラントは天然歯のように自然に見えそして感じ、虫歯や歯周病などに罹患しない利点もある。
骨吸収もなく、健康な隣在歯が削られる必要がないので、歯質も保存できる。限られた寿命のブリッジと違って、インプラントはほとんど永久的で問題が少ない。

Large
Gaps
Here, too, implants represent the ideal alternative. They can
either be used to replace each missing tooth as an individual unit
(like individual natural teeth), or else they can be used to serve as
supporting abutments for replacing the missing teeth with a permanent
fixed bridge attached to the implants rather than the adjacent natural
teeth.
In
either case, the replacement teeth feel and function like the natural
teeth they are replacing and the remaining natural teeth are not
compromised. |
 |
Shortened
Rows of Teeth
If the molars are missing, the conventional solution is to restore the
teeth with a removable partial denture. Removable
"partials" are usually uncomfortable and are the least well
tolerated dental prosthesis.
Additionally,
they often cause damage to the bone and to the remaining natural
teeth. Implants, on the other hand, allow solid fixation of a
replacement that looks and feels natural. |
 |
Fully
edentulous ("toothless") jaws
Provided there is adequate bone, complete removable dentures can be
eliminated by substituting permanent fixed teeth attached to dental
implants. A complete jaw of teeth can be replaced with as few as
five implants in the lower jaw or eight implants in the upper jaw.
If
fewer implants are desired, two or four can be used to provide stable
support for a removable prosthesis. In either approach, it has
been proven that the use of implants significantly improves the
quality of life while stopping progressive bone deterioration, which
is the usual sequela of wearing removable dentures. |
|
| The
procedure |
| The
dental implant is an artificial foundation (or anchorage unit) that
replaces the natural tooth root. The implant body (a small
titanium post) is inserted into the jawbone in a short office
procedure using a local anesthetic. Titanium is a space-age
metal to which bone tissue unites directly, forming a permanent
biologic bond. |
 |
 |
 |
| Your
prosthesis can be removable, fixed or a combination.
Here a single tooth is fixed directly to the abutment. |
This
type of prosthesis is carefully fitted to your mouth and then
entire metal frame is then permanently fixed to your
abutments. |
This
removable prosthesis clips firmly to the abutments with a bar
device, but can be taken out for ease of cleaning |
|
| The
bonding process is completed rapidly, often in as short as six
weeks. During this "bonding" period, the patient wears
temporary replacement teeth at all times. Unlike in the past,
today's modern techniques have eliminated the need for a second
surgical intervention when, in a second phase after bonding is
complete, the replacement teeth are fastened to the implants. |
 |
 |
 |
 |
| Healthy,
clean, single-tooth implant (without healing cap) ready to
receive abutment. |
The
abutments will take one of several shapes, depending on which
type of replacement prosthesis your dentist feels is best for
you. |
Before:
One single-tooth implant with abutment already screwed into
place, ready to receive new replacement tooth. |
After:
Careful restoration to ensure the best fit, results in natural
look and feel, even close up. |
|
| The
result is stable teeth, which restores the natural function and
appearance of the mouth and which patients say feel and look
natural. The PERMADENT® permanent replacement teeth have
the added advantages that they are rarely affected by dental disease
and they usually last a lifetime. |
| Who
is a candidate? |
| Provided
the anatomical and medical health requirements are acceptable, any
missing teeth can be replaced with the aid of dental implants.
Age is only a factor in the sense that implants cannot be done until
the jaws have stopped growing (about 15 to 16 years of age). |
| There
is no upper limit to the age at which implants can be done and age
does not seem to be a factor in success rates. The availability
of adequate bone is of critical importance and for that reason not
everybody is a candidate for implants. |
| Only
after an assessment of the patients' health, including an oral
examination and X-rays of the jawbone, can implants be
recommended. The basic prerequisites for an implantation are
adequate bone quality and quantity and normal wound healing capacity
of the body. |
| Results |
| Several
million people worldwide have experienced the benefits of
implant-based tooth replacement. Implantology has become an
integral part of every-day dentistry and in many respects, it is the
most desirable method of tooth replacement. |
|
|
| More
than 30 years of clinical studies as well as our own thirteen years of
clinical experience have shown the PERMADENT® type procedure
to be predictably long-lasting, far exceeding the current standards
for other forms of conventional dental replacements. |
| Your
next step |
| While
the PERMADENT® procedure can work for people of all ages,
every person has unique physical requirements and esthetic desires,
which must be taken into account and discussed in evaluating the
benefits of this procedure. Not every person is a candidate and
eligibility can only be determined during an individual
consultation. The PERMADENT® dental implant center
offers a private consultation at no charge. |
