1. Why do
we lose our teeth? |
| |
| There are
several reasons that make the
dentist to extract a tooth,
such as advanced gum disease
(the bone that held the tooth
is lost); advanced decay that
could make impossible the tooth
to be reconstructed; or root
fracture, normally after an
accident. |
 |
|
|
| |
2. What
happens when we lose our teeth? |
| |
| Some of
the consequences of the tooth
loss are: esthetic compromise;
decrease of masticatory efficiency
(it is harder to chew); overload
of the remaining teeth that
will have to make the function
of the lost teeth (therefore
the remaining teeth could be
injured or lost too); difficulty
to talk or to say certain words;
loose of lips support (wrinkles);
inclination of the neighbor
teeth; unstable bite; head and
face muscles and articulation
problems; decrease of the size
of the bone that held the lost
teeth (bone resorption). |
 |
|
|
| |
3. What
are the options to replace the missing
teeth? |
| |
| The simplest
option is the removable denture,
which is retained by hooks,
and stabilized by a plastic
or metallic structure that covers
the palate or the tongue zone.
The patient can remove it from
the mouth.
The next option
is the bridge, which consists
on trimming the neighbor teeth,
to make porcelain crowns on
them fixed to another crown
that will replace the lost tooth.
The third
option consists on placing an
artificial titanium root (dental
implant) that will support a
porcelain crown. |
 |
|
|
| |
4. What
is an implant? |
| |
| An implant
is an artificial object that
replaces a lost part of our
body. This way, it will work
as part that we have lost. |
 |
|
|
| |
5. What
is a dental implant? |
| |
| Dental
implants are small titanium
cylinders (3.75 mm. Diameter)
that work as artificial dental
roots, once they are placed
inside the jawbone. This way
the artificial teeth can be
anchored in these new roots
(zero to four months after their
placement, once the dental implants
(artificial roots) have fixed
strongly to the bone), contributing
to recover a beautiful smile,
as well as a comfortable speaking
and chewing. Dental implants
will allow us to chew with total
comfort, and to smile and speak
with the same security than
with our own teeth. With the
use of the dental implants,
there is no need to touch, trim
or injure the neighbor teeth,
to replace the missing tooth.
The dental implants that have
shown a very long-term success
rate are the osseointegrated
dental implants, that actually
integrate to the bone. |
 |
|
|
| |
6. What
is an osseointegrated dental implant? |
| |
| They are
a type of intraosseous dental
implants that fix to the bone
by means of the phenomenon of
" Osseointegration ",
creating true artificial roots
implanted inside the mandible
or maxillary bone, giving a
solid base to built solid restorations
to replace one or several lost
teeth that will work exactly
the same as our natural teeth.
Osseointegrated implants will
allow us to chew with total
comfort, and to smile and speak
with the same security than
with our own teeth. |
 |

7. Which are
the disadvantages of using dental
implants? |
| |
| a) Dental
implants must be placed inside
the bone through a small surgery,
which is painless but make some
patients feel anxious.
b)
The other disadvantage is the
time to wait from the implants
placement to the crown placement,
or primary osseointegration
time, that is two to six months,
depending on the area of the
mouth where the teeth were lost.
During that time the patient
can wear a temporary bridge
o denture that could be fixed
or removable. |
 |
|
|
| |
8.Which
are the advantages of using dental
implants? |
| |
| a) The
main advantage of dental implants
consists on not trimming (damaging)
the neighbor teeth to replace
the lost teeth: even tough natural
tooth supported bridges have
been a good option, they are
no longer the best, since their
life is 7 to 10 years, and when
they fail it is because one
or more of the supporting teeth
fail, due to overload or to
decay coming inside the tooth.
Then, the supporting teeth are
lost too (sometimes they can
be saved by root canals), and
a longer bridge has to be done,
so more teeth have to be trimmed.
This problem had been avoided
if an implant had been placed
the first time, instead of the
bridge.
b) The hygiene
for maintaining healthy a bridge
is more difficult than for implants,
since regular dental floss cannot
be used because the crowns in
the bridge are fixed together.
Therefore, a special technique
with a special floss has to
be used for bridges. On the
contrary, implant-supported
crowns can be easily flossed
(same way as natural teeth),
since the restoration is independent
of neighbor teeth.
c) Life for
an implant is longer than for
a bridge or a removable denture:
In 10-years studies, it was
found that success rate for
implants was 90%; meanwhile
for bridges and dentures it
was 50%. It was also found that
when a bridge failed, supporting
teeth had to be extracted or
submitted to root canal treatment
very often. The few times that
implants failed, it only had
to be changed, with no harm
for the neighbor teeth.
d) Removable
dentures induce a wider loss
of the bone that held the natural
teeth. Once that bone loss has
advanced, it is impossible to
retain a removable denture,
and then a bone graft has to
be placed. On the contrary,
dental implants stimulate the
bone; therefore its loss is
avoided. |

9. What
material is used for dental implants? |
| |
| Along the
history of dentistry and medicine,
many materials have been used.
At the present time, the only
material considered valid for
dental implants is titanium. |
 |
|
|
| |
10. Why titanium? |
| |
| There are
countless researches that demonstrate
that titanium is the best biomaterial,
given its excellent biocompatibility
to the human organism.
Since it fixes
to the bone (osseointegration),
it has demonstrated to last
for very long periods of time.
There are research studies that
support the use of implants
that have been working for more
than 35 years, with a very high
success. All this makes titanium
the election material. |
 |
|
|
| |
11. What is
the purpose of using dental implants? |
| |
| The main
purpose of implants is to work
as artificial roots that will
hold the crowns placed instead
of the lost teeth. Implants
restorations fulfill three basic
concepts:
Function and esthetics:
chewing, speaking and smiling
can be done comfortably; they
also provide lips support.
To stop the bone resorption,
since they stimulate the bone
that holds them.
To eliminate the overload
of the remaining teeth that
could appear if bridges were
used. |
 |
|
|
| |
12. How do
implants contribute to recover the
function and the aesthetics? |
| |
| Dental
implants substitute the removable
dentures for fixed teeth, improving
the function and the aesthetics
simultaneously.
They support the new crowns
without the need of trimming
the natural teeth, allowing
us to chew with total comfort,
and to smile and to speak with
total security, for many years.
The implant-supported crowns
can be easily cleaned with dental
floss. |
 |
|
|
| |
13. What is
the bone resorption and why does it
happen? |
| |
| When we
one or all the teeth in our
mouth, (probably because of
decay, gum disease, traumatism,
etc.), a process of bone loss
or bone atrophy begins. The
function of the maxillary and
mandibular bone is to support
the teeth. When these teeth
are lost, a process of bone
reabsorption begins that is
accelerated in most of the cases
for the pressure of the removable
denture .In some occasions the
reabsorptions is so large that
it is almost impossible tolerating
or achieving good retention
in a traditional removable denture.
The esthetic and functional
consequences can be dramatic.
The widest bone loss happens
during the first months after
the tooth is lost. |
 |
|
|
| |
14. How do
dental implants contribute to stop
the bone resorption? |
| |
| With implants
we don't only replace the teeth
that we have lost, restoring
the function and the Aesthetics
The bone loss is also stopped
because the bone receives the
stimulus of the mastication
again. Therefore, it is important
to replace the missing teeth
with implants as soon as possible
after they were lost. |
 |
|
|
| |
15. How do
dental implants contribute to diminish
the overload of the remaining teeth? |
| |
| Let us
imagine the example a house.
The teeth would be the columns
or pillars for support of the
roof.
If we
were removing columns, the rest
of them would have to support
the whole weight of the structure.
The remaining columns would
be overloaded, and there could
be a moment when the roof falls.
In the mouth the same thing
happens, when teeth are lost.
The remaining teeth have to
support all the forces of the
mastication, suffering an important
overload that could injure them
and their bone support, and
with time they could be lost
too. |
 |
|
|
| |
16. How is
the treatment? |
| |
| The treatment
consists on two stages
a. Surgical phase
b. Prosthetic phase. |
 |
|
|
| |
17. What is
the surgical phase? |
| |
| The surgical
treatment consists on the placement
of the artificial roots or implants
inside the jawbone. It is performed
with local anesthesia, and is
painless. Sedation and general
anesthesia are options for nervous
patients. The duration of the
intervention is from one to
two hours, depending on the
number of implants, that will
remain covered for two to six
months (depending on the area
of the mouth where they were
placed).
After that
time sometimes there is a need
of a very small second surgical
phase, to uncover the tip of
the implants, especially in
esthetic related areas. |
 |
|
|
| |
18. How is
the post-operative stage? |
| |
| It is not
painful. The following day of
the intervention the patient
will have a slightly inflamed
area in the face. Painkillers,
antibiotics and anti-inflammatories
are prescribed for a short period. |
 |
|
|
| |
19. Will
I be able to use my removable denture
or bridge as a temporary solution? |
| |
| Meanwhile
the dental implants integrate
to the bone, if you use a removable
denture, it will be modified
and conditioned internally with
a special material, to be used
temporary since the day of the
placement of the implants, until
the implants are ready to receive
the fixed porcelain crowns,
zero to four months later.
If you use a fixed bridge, it
will be cemented immediately
after the placement of the implants,
to be used temporary since the
day of the placement of the
implants, until the dental implants
are ready to receive the fixed
porcelain crowns, zero to four
months later. |
 |
|
|
| |
20. When will
the new teeth be placed on the dental
implants? |
| |
| The time
between the surgical phase and
the placement of the crowns
varies depending on the case.
The range
varies between two and six month,
to give time to the implant
to integrate or fix to the bone.
More time could be waited if
the patient asked so (i.e. because
of a trip). |
 |
|
|
| |
21. How does
the new prosthesis or crown anchors
to the implants? |
| |
| The system
used consist on a series of
very precise machine made abutments
that anchors to the implant
with a gold screw, and that
will retain the crowns. |
 |
|
|
| |
22. Is it
necessary to brush the new implant-supported
teeth? |
| |
| As natural
teeth, implants should receive
daily flossing and brushing.
The flossing of the implant-supported
crowns will be much easier than
for teeth supported bridges,
because the first ones will
not be fixed to the neighbor
teeth. |
 |
|
|
| |
23. Am
I an ideal candidate for dental implants? |
| |
| If your
answer is affirmative to some
of the following questions,
you can be considered a ideal
candidate to be treated with
implants:
Have you lost one, some
or all of your teeth?
Do you have difficulties
with your removable denture
(bad retention, pain, etc)
Do you feel insecure
when you smile, when speak or
to eat?
Has a dentist told you
that you have teeth in very
bad shape?
Is there an area in your
mouth where the corresponding
tooth never showed up? |
 |
|
|
| |
24. Is age
a limit? |
| |
| The age
is not a decisive factor when
being candidate for implants,
but it is advisable not to use
them before the 15 to 16 years
of age, until the maxillary
growth has completed. Older
patients can receive implants
as well as the young ones, with
the same success rate. |
 |
|
|
| |
25. Is it
a painful treatment? |
| |
| No. A treatment
with implants demands a surgical
intervention, but pain and all
the other implications can be
perfectly controlled. |
 |
|
|
| |
26. How long
does the treatment take? |
| |
| It is very
important to respect the times
of osseointegration or integration
of the implant to the bone.
In general it takes two to four
months for the lower jaw, and
six months for the upper jaw,
between the time of the implant
placement, and the prosthetic
phase (start of the construction
of the implant supported crowns
or dentures). The prosthetic
phase last from one to three
weeks, depending on the case. |
 |
|
|
| |
27. Could
there be a failure? |
| |
| In spite
of the excellent clinical results
obtained with implants (93 to
97% success rate) there is a
3 to 7% rate for failure. No
other dental treatment has such
a high success rate for long
terms. |
 |
|
|
| |
28. What does
it happen if a dental implant fails? |
| |
| If an implant
fails, it is possible to substitute
it for another one to solve
the problem.
Anyways, most of the implant-supported
prosthesis are designed to work,
even if an implant failed. |
 |
|
|
| |
29. Will the
dental implants last a lifetime? |
| |
| In medicine
it is complex to say that a
treatment is for a lifetime,
specially being the teeth a
tool that we use every day and
in each moment, that receive
a lot of pressures and forces,
and placed in a humid and very
septic area (the mouth). Anyways,
there are studies older than
35 years that show a very high
success rate. The most recent
studies say that 90% of the
implants placed 10 years ago,
are still working in the mouth
today. It is much higher than
the 50% success rate for ten-year
periods described for tooth-supported
bridges or dentures. |
 |
|
|
| |
30. Is the
dental implant treatment expensive? |
| |
| The implant
treatment is sophisticated and
it demands a very complex armamentarium.
More than
one experienced professional
(specialist) is required; the
components used have to be very
precise, and precious metal
alloys (gold, silver, palladium)
have to be used in the prosthetic
phase. The implants and the
prosthetic components have to
be from a recognized brand.
Al that makes the implant treatment
more expensive than the tooth
supported treatment, at first.
But with time, since implant
treatments last longer, with
the re-doing of the tooth-supported
bridge or denture (sometimes
it implies root canals, extraction
of supporting teeth, longer
bridges, etc) it is possible
that the implant treatment results
less expensive, and will prevent
the lost of the natural teeth. |

Why Costa Rica for dental implants? |
| |
| Costa Rica
is a peaceful small country
in Central America that is also
known throughout the world for
its high quality, low cost dental
care.
Politically stable, and with
no army, Costa Rica is one of
the most bio-diverse countries
in the world: 25% of its territory
is dedicated to parklands and
wildlife refuges.
Tourist love Costa Rica’s
natural attractions, from beaches,
deep-sea fishing, white water
rafting, and surfing, to mountains,
rain forests, volcanoes and
hiking. The capital city of
San Jose offers museums, a national
theater, and casinos. All Visitors
love San Jose's central market
. You can also visit coffee
plantations, butterfly farms,
and villages offering local
handicrafts - all within a twenty-mile
radius!
Costa Rican's are known for
their warmth and hospitality.
It is safe and easy for patients
from other countries to have
their dental implants treatment
done in Costa Rica, and meet
this beautiful country between
appointments, all for a much
lower price, even tough most
of the materials, including
the dental implants we use are
made in the United States and
Europe |
 |
|
|
| |
32.
What is an specialist |
| |
| According
to Costa Rican Law, an specialist
is a dentist who, after the
regular
six years of Dentistry, Studied
at least two more years (full
time) of an
specific branch of dentistry.
This has to be certified by
the official Costa
Rican Board of Dentists, that
review the program and the University
that
offered the specialty (some
programs may not be accepted
as specialty, if they
do not reach a degree of excellence).
The Costa Rican Board of Dentists
prohibits (article 29th, Code
of Ethics) the
dentists to say or announce
an specialty, if they have not
accomplished those
requirements.
There are only three certified
Specialists in Oral Implants
in Costa Rica, and
Dr. Anglada is one of them. |
