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.

 


 
Implant placement process
In the traditional method, two surgeries are required, with three to six months between them. During the first surgery, an incision is made in the gum where the implant will be placed. A hole is drilled in the bone, the implant is placed into the hole in the bone, and the incision is stitched closed.

At the end of the healing period, a second surgery takes place. It involves making a new incision to expose the implant. A collar, called an abutment, is screwed onto the top of the implant. The abutment is used to support the crown.

One-stage implant – The implant is placed into a new, healing or healed extraction site and is visible above the gum immediately after placement. The advantage of this method is that a second surgical stage is not necessary to expose the implant. In this procedure, your dentist can place the implants, and place a temporary crown or bridge all in one visit. The implant will not normally be ready to support a tooth for several weeks of months.
  
Two-stage implant – The implant is placed into a new, healing of healed extraction site and then covered by a layer of gum so that it cannot be seen – this is the first stage. At the second stage some weeks of months later, the implant is uncovered and components added bringing it above the gum ready to begin placing a new tooth.

Same day implants – This technique is most often used to treat the lower jaw and requires considerable planning before the actual day of surgery. Several implants are installed and a few hours later a complete arch of temporary of permanent teeth can be fixed in place. If temporary teeth are used these will normally be replaced with a permanent bridge after a suitable healing interval. Not all patients are suitable for this style of treatment.

Immediate implant – For this technique a tooth is removed and an implant placed immediately into the extraction site. Depending upon the local bone and soft tissue conditions, the implant surgery may be a one- or two-stage procedure. Not all patients are suitable for this approach.

Immediate implant and early loading – This is distinctly different from an immediate implant placement. It is effectively a one-stage technique where the implant is placed into a new, healing or healed extraction site and is fitted with a new tooth at the same appointment. This first tooth will normally be kept out of direct contact with opposing teeth for a healing period of more than 3 months, after which it is finally restored. This technique tends to be more common in regions of the mouth where optimum aesthetics are important. Again, not all patients are suitable for this approach.
How long will the implants last?
Will I feel pain during or after the procedure ?
During the period after the new teeth are fitted, the success of each treatment stage will be the main factor determining how the implants are performing. Once the implants and surrounding soft tissues are seen to be healthy and the new teeth comfortable and correctly adjusted, it is the quality of your home care and willingness to present for regular maintenance reviews that will have most influence on how long they will last.

When poorly cared for, implants will develop a covering of hard and soft deposits (Calculus and plaque) which is very similar to that found on neglected natural teeth. Untreated, these deposits can lead to gum infection, bleeding, soreness and general discomfort, just as can occur around natural teeth. It could probably be said that implants much like teeth will last for as long as you can keep them clean.

Well maintained implants placed into adequate bone can be expected to last for many years and probably for your lifetime. However, just as you would expect conventional crowns, bridges and fillings to need occasional repairs or replacements during their lifetime, you
implant-supported teeth may also have similar maintenance requirements over theirs.
