Fifty-five million teeth, according to the American Dental Association, will
be lost this year due to infection, gum disease or accident.
As a result, the victims of these lost teeth face short- and long-term
consequences; remaining teeth that shift, rotate and become crooked; bad bites
and difficulties in chewing food properly; and unsightly spaces that undermine
their appearance.
Dentures, for many, are not the answer. In many cases, dentures slip causing
sore spots, limit the foods that can be eaten, and don't look like natural
teeth.
As a result of these factors and a number of recent technological breakthroughs,
Dr. Notis have seen a dramatic increase among their patients in
the use of dental implants. Implants offer patients a second chance for teeth
that look and feel natural. They replace the form and function of missing teeth
and support replacement teeth in the same way a root supports a natural tooth.
Implants can either support dentures so they stay in the mouth and will not
shift or fall out, or replace them with permanent "teeth." Implants also keep
the bone stressed and stimulated, preventing eventual bone loss. The long use of
dentures, meanwhile, leads to bone atrophy and, over a number of years, a "caved
in" appearance around the jaw line.
Computer-assisted technology has taken much of the guesswork out of implant
surgery and, as a result, offers patients a number of significant benefits. It
allows dentists to do virtual surgery long before the patient is prepped for
surgery. This means all the planning can occur before the procedure starts. A
catscan of the patient's mouth is taken, put on a floppy disk and inserted into
the computer. This allows the dentist to see the anatomy and height and width of
the bone and to rotate the angulation so they can pinpoint the placement of the
implants to maximize their success.
The computer-assisted system also allows specialists to measure the exact degree
of the proposed implant. This is important because the odds of a successful
implant decrease if the angle exceeds 30 degrees. Since the dentist no longer
has to evaluate and determine a strategy at the time of the procedure, time can
be reduced by as much as a third.
This is one of the reasons why dentists can now offer single-stage implants to
about a third of their patients (typically those where implants are adjacent to
natural teeth). This means that only procedure need be performed - rather than
two separate ones - making only three or four patient visits necessary from
implantation to attachment of the replacement teeth.
The material used today for implants has also made the procedure more
dependable. The use of titanium and materials made from variations of it last
longer and greatly increase the likelihood of osseointegration - connection of
the implant to the bone.
