INTRODUCTION
Most people know about the technology of dental implant, but still many of them only
know the existence of the word, they do not know about the detail of dental implant.
Nowadays, dental implant changes the way people live. The dental implant sis designed to
provide a foundation for replacement teeth which look, feel, and function like natural teeth.
People who have lost teeth regain the ability to eat virtually anything, knowing that teeth
appear natural and facial contours will be preserved. Patients with dental implant can smile
with confidence.
Dental implant substitute missing teeth or broken teeth with artificial teeth to repair the
function and esthetic in mouth. Own a small titanium implant posts, embedded in the jawbone,
they act as anchors for a replacement tooth, also known as a crown, or a full set of replacement
teeth. Besides that, implants also help preserve facial structure, prevent bone deterioration
that occurs when teeth are missing.

OBJECTIVES
Dental implant brings us to a new way of repairing teeth and consider as a new technology so
this research has some purposes. Firstis to describe the preparation for having dental implant,
secondis to grasp the advantages and disadvantages of dental implant.
METHODOLOGY
Because dental implants require one or more surgical procedures, you must have a thorough
evaluation in preparation for the process. The process involves:
At the first appointment, the dentist or oral surgeon performs a thorough examination to
determine whether implants are appropriate to replace the missing teeth. Often, x rays are
necessary to discover the state of the jawbone, particularly if the teeth have been lost for some
time. This information is used to determine if implants are appropriate and, if so, what
particular type of implant would be best for the clinical situation. The planning process may
involve a variety of dental specialists, including an oral and maxillofacial surgeon, a doctor who
specializes in conditions of the mouth, jaw and face; and a periodontist, a dentist who works
with the structures that support teeth.
There are two solutions commonly used if the initial examination indicates that the bone in the
area where the implant is to occur is too resorbed to support the implant. The first is bone
grafting. This involves undergoing a procedure that moves bone from one place in the body to
another to enlarge the bone structure at the implant site. Often, bone can be moved from one
place in the mouth to another. Sometimes a graft from a donor or an animal or artificial bone

can be used if bone from the patient is not available. Grafting usually is done four to eight
months before the implant procedure, to allow the graft a chance to heal before it is disturbed
with the implant process.
A second solution is the use of subperiosteal implants that ride above the bone but beneath the
gum. These types of implants are not placed in the bone. A CT scan is commonly used to obtain
a model of the bone structure and then the implant fixture is molded to precisely fit the bone
model.
Be sure to tell your doctor about any medical conditions you have and about any medications
you take, including prescription and over-the-counter medications and supplements. If you
have certain heart conditions or orthopedic implants, your doctor may prescribe antibiotics
before surgery to help prevent infection.
You will be given some form of anesthesia for pain control during surgery. Anesthesia options
include local anesthesia, sedation or general anesthesia. Talk to your dental specialist about
which option is best for you. Your dental care team will instruct you about eating and drinking
before surgery, depending on what type of anesthesia you have. If you're having general
anesthesia, plan to have someone take you home after surgery and expect to rest for theremainder of the day.
Most dental implants are successful. Sometimes, however, the bone fails to fuse sufficiently to
the metal implant. Smoking, for example, can contribute to implant failure and complications.
If the bone fails to fuse sufficiently, the implant is removed, the bone is cleaned up, and you can
try the procedure again in a month or two.

ADVANTAGES
1. Dental implants are very durable
Dental implants, composed of titanium metal that "fuses" with the jawbone through a
process called "osseointegration", willnever decay. Therefore,with a proper care, the
implants will last a lifetime.
2. Improving speech
A person without the tooth cannot speak fluently and clearly. It willoften sound like a
mumble, because the form of the mouth can determine speech. Therefore, the dental
implants can retrieve the form of the mouth to its natural form so it can recover speech.
A denture cannot revive the ability to speak as perfectly as dental implant because the
tooth become unstable and loose when the dentures assembles with it, so the ability to
speak does not recover perfectly.
3. Eating easier
Chewing is difficult with dentures that slide. Since implants are designed to fuse with
bone, they function like your own teeth and make eating your favorite foods enjoyable
again.
4. Lower risk of losing bone tissue
The human body reproduces bone tissue as a part of its natural processes. This also
involves the renewal of the bone tissue surrounding the tooth. Therefore, the human
body does not lose any bone tissue, unless the natural processes are disturbed when a
tooth is lost. Gradually, a cavity will develop in the bone tissue instead of the missing
root and the bone tissue will start deteriorating, which is known as atrophy of the bone.

One of the consequences of this process is the alteration in the structure of the
jawbone. This can be experienced by patients who have to have their dentures modified
frequently due to atrophy worsening. This process can seriously impair the patients
dental health and even result in rapid ageing due to the jaw losing shape and causing
the face to droop. Fitting dental implants into the bone allows the body to continue the
natural renewal of the bone tissue.
5. Natural appearance
If the treatment is of a high quality, the implant should look naturally and match the
patients healthy teeth. Dentures, on the other hand, frequently loosen when used for a
longer period of time and are likely to differ in appearance from the patients other
teeth. Bridges are kept in place with metal constructions that result in the tooth
appearing darker and thus unnatural. Therefore, dental implants are the best solution
for achieving the most natural look.
6. Dental implants do not require removing healthy teeth
In the case of using dental bridges for tooth replacement, the healthy teeth surrounding
the gap have to be used for supporting the structure. If the artificial structure is
damaged in any way, this may result in the need to remove completely healthy teeth
that have been used to support the bridge. In the case of dental implants, surrounding
teeth are not used in the process and cannot experience any damage.
7. Easier dental hygiene
Dental implant closely resemble natural teeth and do not require any other special
forms of attention apart from brushing and flossing, which are a normal part of

everyones oral hygiene, and regular dentist checkups. Dental implants do not need
extra attention, while bridges and dentures have to be removed from the mouth in
order to be cleaned

DISADVANTAGES
1. Dental Implant can be expensive
One of the disadvantages of a dental implant is the cost. Compared to other alternatives
for replacing a missing tooth or teeth, cost can be quite high. With the average cost of a
dental implant being about $3600, dental implants can be a costly alternative for
replacing a single tooth. Included in the price is the surgical placement of the dental
implant and its restoration with a crown.
2. The Long Duration of Healing Process
Another disadvantage of a dental implant is the length of time required from initial
dental implant placement to implant restoration. The treatment time can vary from
approximately three months to six months. This depends on the area where the implant
is placed, the necessity for adjunct procedures like bone grafting, the quality and
quantity of healthy bone and overall health of the dental implant recipient.
3. Damage to dental implantsAnother problem is a structural failure of a dental implant. After the dental implant has
fully integrated with bone and complete healing has occurred a dental implant can
fracture partially or completely if there is excessive pressure exerted on it. This can
occur during a traumatic episode such as a blow to the face or excessive forces exerted
on the dental implant over a period of time. A crown that is not properly calibrated or
teeth grinding can cause excessive and destructive forces. These forces can be
detrimental to implants as well as natural teeth.
4. Damage to the sinus cavitiesThe sinus cavity which is connected to the sinuses is also directly linked to the bone that

the dentist uses to secure the dental implant. If the dentist is not careful enough, the
patient might risks their sinus tissue damaged in the process of drilling.
5. Limited usageAfter undergoing the procedure of fixing dental implants, the patient might not treat the
new implant with appropriate care and act like having completely healthy natural teeth.
However, the patient should take extra precautions for the few weeks while the implant
is healing, for example, not use the artificial tooth for vigorous biting. There is a bigger
risk of overworking the dental implant if it is supporting two or more teeth. If at all
possible, it is advised that each denture is supported by a separate root implant, since it
most closely resembles the natural conditions of dental.
6. May trigger an allergic reaction
Most dental implant used today is made out of titanium alloy. Titanium is a non-toxic
substance, which can trigger an allergic reaction in certain people. As a result of a
production process, titanium alloy contain traces of nickel. This can potentially cause
health problems, including hypersensitivity reaction, which can be falsely attributed to
titanium. Only about 4 percent of individuals tested will show signs of an allergic
reaction to titanium. The hypersensitivity reaction may show a range of symptoms, from
red and itchy affected area to Chronic Fatigue Syndrome. The MELISA
test is the only
scientifically-proven test which can objectively diagnose titanium allergy. If you are
planning to have a hypersensitivity test before having titanium dental implant placed, it
is advised to find out the exact composition of the implant.
7. Decementation of a dental implant
Decementation of a dental implant supported crown, although very rare, can also be
encountered. The main reason for a dental crown displacement is improper positioning
of a dental implant in the bone. Biting forces or occlusal forces place pressure on the

crown in areas that do not have proper support. This causes the crown to eventually
come off. If the implant crown is displaced, a new one will need to be fabricated. This
can be quite expensive since an average cost of a dental implant crown is about 1800
dollars.

CONCLUSION
Dental implants are frequently the best treatment option for replacing missing teeth or having
an injured ordisease at his/her tooth. Rather than resting on the gum line like removable
dentures, or using adjacent teeth as anchors like fixed bridges, dental implants are long-term
replacements places in the jawbone.Composed of titanium metal that "fuses" with the
jawbone; dental implants never slip or make embarrassing noises that advertise the fact that
you have "false teeth," and never decay like teeth anchoring fixed bridges. Because dental
implants fuse with the jawbone, bone loss is generally not a problem. Furthermore, if properly
cared for, dental implants can last a lifetime. Despite ofits disadvantages, dental implant should
be consideredforreplacing tooth.
