During the last 30 years the use of dental implants has changed
dentistry beyond recognition. Implants are no longer considered
experimental and it is equally rare to come across situations
where they cannot be used at all.

Today there is another option for patients who are missing permanent teeth.
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 that your
oral and maxillofacial surgeon surgically places in the jawbone. Composed of titanium
metal that “fuses” with the jawbone through a process called “osseointegration,” 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.
 


 
Complications from Surgery :
  Any surgery carries the possibility of complications. Complications of implant surgery include bleeding, infection and injury to nerves, sinuses (located above your upper teeth) or nasal cavity.

When implants are used to replace lower teeth, your dentist could nick the nerve that runs
through the jawbone during drilling. This can cause pain or numbness. If numbness occurs, it usually affects the lower part of the lip and chin or one side of the tongue. It can last for several months until the nerve heals or it may be permanent.

In the upper jaw, there is the possibility of drilling through the jawbone into one of your sinuses
or nasal cavity, which could result in an infection. To avoid this, special X-rays will be taken prior to your surgery will help the surgeon to determine where the nerves, sinuses and nasal cavity are located.
  
 

Implant Failure :
Implant surgery is successful more than 90% of the time. Occasionally, an implant fails to bond with the surrounding bone. Potential reasons for implants failing to integrate with surrounding bone include:
  • Surgical trauma
• Infection around the implant
• Smoking – This appears to decrease blood flow to the healing gums and bone, which could
interfere with the bonding process.
• Lack of healthy bone –If there is not enough bone for the implant to remain stable, the implant may move around within the bone and bonding will not occur.
• Titanium allergies –These are extremely rare.
Implant Failure :
1. Diagnosis and treatment planning after which it may be necessary to carry out repairs or treatment to any remaining teeth.

2. Implant placement is usually followed by a period of healing lasting from 6 weeks to 6 months. Often the implant are completely hidden beneath the gum, however one-stage procedures where the implant is visible from the time of placement are also commonplace. Stitches are normally removed 7 to 10 days after the implant placement.
3. Several visits may be needed over the next few weeks to adjust temporary teeth of dentures and to monitor healing.

4. Once the implants have healed uneventfully for the required time, they are uncovered if necessary and made ready to connect the teeth. Sometimes the time allowed for implants to integrate may be increased or decreased to suit the local bone conditions and the overall quality of healing.

5. In some cases the first teeth fitted to your implants are not the final ones, but replicas of the intended design. This stage can be used to assess the implants, control early loading and in areas where aesthetics are more critical, also gives the gums time to mature around each implant before final teeth are fitted.

6. Final teeth are commonly fitted between 3 and 9 months after the implants were first placed. The way that the teeth fit together is carefully adjusted so that they do not interfere with each other.

7. Regular examination and hygiene appointments are then all that is required to maintain the health of the mouth, teeth and implants.
