Implants: Restoring a Solid Foundation
Tooth Root Substitutes
Sometimes people lose permanent teeth due to accident, injury,
disease or extraction. In such cases, we find dental implants
to be a secure, functional replacement option. A dental implant
is simply an artificial tooth root replacement consisting of a
tiny titanium post inserted surgically into the jawbone, covered
by a customized restoration. After placement, under normal circumstances,
the titanium post actually bonds chemically to the jawbone, thus
serving as a secure, supportive structure for the chosen restoration.
In addition to using implants to replace missing teeth, Dr. Goldberg
may sometimes recommend implants as anchors for bridgework or
fixed dentures as well.
Long Term Advantages
Since they are permanently, surgically anchored in the jawbone,
implants offer impressive advantages over other tooth replacement
options. Often, they can actually restore comfort and beauty,
while providing long-term stability. Plus, they do not rely on
neighboring teeth for support, and therefore are more conservative.
And finally, this solid foundation means that once they're implanted,
you'll never have to deal with the inconveniences and discomfort
of ill-fitting prostheses again. In fact, you'll probably forget
they're even there.
Unlocking the Secret of Successful Implant Restorations
Depending on how many teeth you're missing, we'll determine the
best kind of restoration for your case. If you're missing one
or two teeth, your restoration will most likely consist of implants
with individual crowns. As the number of missing teeth increases,
you'll probably require implant-supported fixed bridgework. And,
if we're replacing a complete set of upper or lower teeth, we'll
evaluate the advantages of removable vs. fixed prosthesis, which
in turn determines how many implants per jaw are required.
What differentiates between our choice of doing fixed bridgework
or what we call a combination "Fixed-Removable Prosthesis"
to replace teeth in a fully edentulous arch is the relationship
between the eventual tooth position and the supporting gum and
bone.
If tooth loss is fairly recent and the jaw structure is relatively
intact, there is generally enough bone to place implants at an
ideal level and angulation to permit the fabrication of a fixed
porcelain-fused-to-metal bridge.

However, many people for whom implants are indicated are individuals
who lost teeth from periodontal disease, trauma or have been missing
their teeth for a long time. In most of these instances, enough
time or infection has occurred to cause a significant amount of
bone loss. What this in turn means is that the implants cannot
be placed close enough to the proper tooth position to allow for
the fabrication of an esthetic fixed bridge. Instead, some type
of bar and overdenture combination is necessary because we need
to simulate gums as well as replace teeth.
Implant overdentures have been done for a very long time, and
they have always had one basic limitation
they have typically
been built with some type of snap retentive device (ball and socket,
bar and clip, etc) and the problem is that these attachments wear
and/or break. Constant tightening or repair is costly and frustrating
to patient and dentist alike. To get around this problem we are
among the first in Dallas to use an alternative type of attachment,
the MK1.
This attachment is unique in that it feature a slide type of
interlock which, when activated, holds the overdenture rigidly
in place with virtually no movement so that it acts and feels
just like a fixed appliance. The overdenture can be released and
removed for cleaning simply by using a small "pin" for
deactivating a slide within the attachment. The design of the
attachment features no wearing parts and so our past experience
suggests that there is virtually no loosening and therefore no
repair. If you'd like to see an example of a patient treated with

Choices and Steps
The implant process generally requires three separate steps,
"anchoring", "attachment", and "restoration".
As the 'orchestrator' of a professional implant procedure team,
Dr. Goldberg coordinates each step, the first two of which are
completed by a surgical specialist. Once we've determined that
implants are the best option for you, we work with you individually
to evaluate the specific type of implants appropriate to resolve
your particular concerns, carefully coordinating all steps of
your treatment plan.
The next step includes doing a diagnostic evaluation, from which
we'll create a surgical guide as to how many implants are needed,
and their placement. We then provide this guide to the surgical
specialist, who will then surgically anchor the implant into your
jawbone below the gum tissue. The implant must form a solid, enduring
base with sufficient stability to withstand the tremendous mechanical
pressure involved in normal chewing, so we'll typically allow
three to six months for the post to integrate into the bone. If
indicated during this healing phase, you'll have a temporary bridge
or dentures to maintain esthetics and function.
Once we're certain that your implant post has bonded with your
jawbone, Dr. Goldberg will then take you through a series of appointments,
including taking impressions, obtaining a bite registration, trial
of the implant restoration, fit, and final delivery of your restoration.
Statistics and Commitment
Those unfamiliar with implant technology may question the success
rate of such procedures. Surprisingly enough, the technology is
well over 35 years old, and has proven successful in tooth replacement,
depending primarily on the recipient's health, as well as the
location and function of the teeth being replaced. Teeth placed
in the lower front jaw may be up to 95% successful, while side
or rear placements are up to 90% successful. It's also best if
recipients are in good general health, with proper bone structure
and healthy gums. Often, people unable to wear dentures are among
those who benefit most from implants. On the other hand, chronic
health problems such as clenching, bruxism, or systemic diseases
may decrease the success rate of the procedure immensely. And
it's also recognized that habits such as smoking may reduce their
success as well.
In fact, this brings up a final, important point to consider.
As an implant candidate, it's important to seriously consider
your own commitment to future oral health. As you might imagine,
poor oral hygiene itself is a common cause of implant failure.
This means that you'll want to be sure and brush and floss around
your implants at least twice a day, according to the specific
instructions we give you. Further, you may need up to four annual
professional cleanings to maintain healthy gums.
