An inert post placed within bone for the prosthesis placement is best tooth replacement option. Sometimes Implants go failure due to many reason like infection, failed osseointegration, loose dental Implants, Nerve Damage, Maxillary Sinusitis.

1. WHAT CAN GO WRONG WITH
DENTAL IMPLANTS?

3. COMPLICATIONS
DURING AFTER
Failure in placement Infection
Implant breakage Failed Osseointegration
Nerve Injury Loose dental implants
Sinus perforation Nerve damage
Fracture of bone Maxillary sinusitis
Bleeding Infection
Aspiration Failed Osseointegration

4. FAILURE IN DENTAL PLACEMENT
THIS MAY BE DUE TO –
Improper angulation
Poor spaced implants
Inadequate bone and
tissue coverage for
implant .

5. This may lead to certain problems. Therefore, for a successful
dental implant proper axis, depth, and angle needs to be assured.
Aesthetic
problems
Chewing
issues
Inability to
maintain
hygiene
Difficulty in
making
restorations

6. FRACTURE OF DENTAL IMPLANTS
This may be
due to
overloading of
implants.
May be due to
defect in
Implant design
Implants with
smaller
diameter are
more prone to
fracture.
Tightening of
implants more
than the
recommended
torque.

7. SINUS PERFORATION
– The sinus membrane serves as a biological barrier
from the oral cavity protecting the sinus from
infection.
– If sinus lining is in proximation with the dental
implant, during implant insertion or tapping the sinus
lining may perforate and the implant may go inside
the sinus.
– If it happens the immediate removal of the implant
lodged in the maxillary sinus has to be done otherwise
maxillary sinusitis or foreign body reaction may occur.

9. NERVE INJURY
– Nerves most commonly affected – inferior alveolar
nerve, infraorbital nerve, mental nerve.
– Nerve damage can occur either during implant
placement or during injecting anesthesia , while
raising a flap.

10. Three types of nerve injury occurs :
1. Neurapraxia - There is no loss of continuity of the
nerve; it has been stretched or has undergone
blunt trauma. The paresthesia will subside, and
feeling will return in days to weeks.
2. Axonotmesis - Nerve is damaged but not severed;
sensation returns within 2 to 6 months.
3. Neurotmesis - Severed nerve; poor prognosis for
resolution of paresthesia.

12. INTRA-OPERATIVE BLEEDING
– In patients who already have prolonged bleeding
time like diabetic patients, patient on oral anti-
coagulants, bleeding disorders
– Injury to inferior alveolar canal during drilling,
tapping of implant when the implant is in close
proximity to the canal.
– control of the hemorrhage can be ensured by
compressing the area with the implant or an
abutment.

13. MANDIBULAR ANTERIOR OSTEOTOMY SITE

14. FRACTURE OF BONE
– Although it is more common in atrophic
mandibles as they are associated with
diminished blood supply.
– May occur during implant insertion or during
tightening of implants when adequate
mandibular support is not provided.
– Radiological examination should be thoroughly
evaluated for height and labial-lingual width of
mandible.

15. ASPIRATION
Instruments like screw driver ,
healing caps, abutments are to
be carried into their surgical site
with extreme precaution
because if they slip there are
chances that patient might
apirate/ swallow them and it
will be a case of extreme
emergency as airway patency
can get compromised and these
patient require immediate
hospitalization.

16. LOOSE DENTAL IMPLANTS
• The normal healing period of an implant is 3-6
months during which osseointegration occurs. If the
implant is loose, it means it has lost integration with
bone and is no longer in contact with it.

17. It may be due to many reasons
Infection post-
surgery
Inadequate
amount of
bone available
Micro-motion
during loading
the implant
Poor surgical
technique during
placement
Over
preparation of
the site
Traumatic
surgery
Smoking after
the procedure

18. PERI- IMPLANTITIS
• It is the inflammatory change that takes place in the
soft and hard tissues surrounding an osseointegrated
implant.

20. • The causes may be :
Contamination of implant via accidental contact with
the implants or indirectly from gloves or instruments.
Improper soft tissue closure can lead to bacterial
contamination around the bone resulting in
destruction of the tissues surrounding the implant.
Unequal occlusal load distribution, which may lead to
loosening of the implant and chances of infection in
the surrounding area increases.
Patient unable to maintain oral hygiene.
If a patient is chronic smoker or alcohol consumer.

21. POST – OPERATIVE BLEEDING
– Laceration of tissues caused by tight or sharp
suture material or by incorrect suturing technique
– Masticatory trauma
– Secondary hemorrhage can occur due to
loosening of sutures.

22. MAXILLARY SINUSITIS
– Close approximation of Sinus to the dental
implants and wound dehiscence in that area can
lead to bacterial contamination and inflammation
of maxillary sinus.
– Displacement of implant into the sinus may cause
a foreign body reaction.
– Use of decongestants with antibiotics and clearing
off the etiologic factor is essential along with sinus
drains.

24. PERSISTENT PAIN DUE TO
PROXIMITY TO CANAL
• The patient may complain
of severe pain post-
operatively if the implant
is in close proximity to the
mandibular canal.
• Retrieval of implant is the
only solution left if the
pain won’t subside by pain
killers.

25. FAILED OSSEOINTEGRATION
• One of the worst complications as it result in
total retrieval of implants.
Failure to follow complete sterilization
protocols
Contamination of implants either
accidently or with gloves or fingers during
placement.

26. Overheating during drilling above 47 degree celcius
in 1 minutes
Decreased healing potential due to underlying
systemic disease

27. CONCLUSION
• Dental implant placement procedure is not easy
as it may seem. The procedure is always
associated with a series of complication that can
be prevented with proper planning, analysis and
treatment.
• There has to be thorough understanding of the
anatomic area in preventing any complication.
Careful selection of cases is mandatory while
knowing the risks and avoiding them.
