Dr. Niznick Re-enters the dental implant market
Niznick’s First Public Showing of New Implant Portfolio On 26 January 2006, Dr. Niznick announced his new dental implant system that will be sold under his recently established dental implant company, Implant Direct. His press release also confirms that he has won the binding arbitration with Zimmer, which has allowed him to re-enter the dental implant market following the expiry of his non-compete clause on 8 January 2006. With the regulatory submission almost complete, we estimate Implant Direct will be in a position to start selling its product portfolio in 2H CY06.
Nobel-Imperfect
We are in the midst of a great competition between dental implant manufacturers to secure the multimillion dollar market that dental implants represent. There have been several battles that have been drawn over the years in this competition. One has been the basic shape of the endosseous dental implant. Another is the micro surface configuration of the implants. A third has been the prosthetic connection war. And, the latest is the configuration of the implant-abutment interface.
The Nobel Biocare company has just released their NobelPerfect Implant, a design developed by Dr. Peter Whorle. The purpose of this implant is to mimic the hyper parabolic curve of the cemento-enamel junction of a tooth. The premise is that if we do this on the implant, we will create an environment for the proper formation of papillae around our implant restoration. There are several other competing companies who have gone a different route by providing implant abutments that have this contour milled into them for much the same purpose.
I have looked long and hard at these designs and can only conclude that there is a great deal of wishful thinking going on here. I am particularly annoyed with the Nobel Biocare company who has switched horses so many times in the mid stream of dental implantology that they have now completely lost all credibility. NobelPharma was the original company and they only wanted to deal with specialists. They froze out the general practitioners for years until they finally realized that the general practitioner is the key to the future of the dental implant company (I told them that somewhere in the mid 1980's.). They then went to a “simplified” dental implant approach and now they are selling a $550.00 implant that seems to me to be fraught with complications (I won’t get into the complications of the new 3I Implant which is a whole different story). There is nothing that is simple about an implant system that will cost about $1500.00 (That means that the patient will have to pay almost $5000.00 per tooth) in parts for the millions of patients who are hard pressed now to pay for dental implants.
The simple truth is the determination of tissue contour and tissue health is based on a very complex series of events that starts with adequate tissues and proceeds through to the contours of the restoration. Implant location is also one of the keys. It doesn’t matter to the soft tissue the prosthetic connection, the shape of the implant or the contours of the abutment (within reason)... only the factors that I just mentioned are important. If you add to this that most of the patients we see are just real hard pressed to get some sort of prosthetic teeth in their mouths so they can go on with their lives, the very expensive Nobel-Imperfect idea does not seem to be very important at all. And, it is certainly not in keeping with the ideals that Dr. Brånemark himself tries to live up to.

Supreme
Court Finalizes Specialty Advertising Rule – FDA Wins!
On
Dec. 9, the U.S. Supreme Court declined Dr. Richard Borgner’s request
for further review of Florida’s specialty advertising statute. The petition
for certiorari that Dr. Borgner and the American Association of Implant Dentists
filed was denied in Borgner v. Florida Board of Dentistry, U.S. Supreme Court
case number 02-165.
The statute prohibits dentists from holding themselves out as specialists in areas of dentistry neither the Florida Board of Dentistry nor the American Dental Association recognizes as specialties, unless they so indicate in capital letters on the advertisement. The statute also applies to dentists who advertise membership in boards the ADA or the Board does not recognize as accrediting organizations.
The FDA’s victory is noteworthy. The last time the U.S. Supreme Court looked at Florida’s regulation of advertising by professionals, it concluded the state could not prevent lawyers from advertising that they also were licensed as certified public accountants.
Court
Won't Consider Rights Of Advertising Dentists
Appeal Of Florida Restrictions Denied By High Court
POSTED: 2:29 p.m. EST December 9, 2002
WASHINGTON -- The U.S. Supreme Court is refusing to jump into another free-speech dispute, this time over advertising restrictions Florida put on dentists.
Justices Clarence Thomas and Ruth Bader Ginsburg say the court should clarify how far states can go in limiting ads of lawyers, doctors and other professionals. But none of the other justices joined them, and at least four must agree before the court will hear a case.
Dr. Richard Borgner of St. Petersburg, Fla., attended 400 hours of classes on implant dentistry, passed multiple exams and was certified by the American Academy of Implant Dentistry. But under a 3-year-old Florida law, any ad listing Borgner's certification also must say in capital or bold letters that the academy is not a "bona fide" organization according the Florida Dental Board.
The law applies to several dental specialties, including cosmetic dentistry,
with professional associations that that are not accredited by the American
Dental Association.

Court Restricts Specialty Advertising in Florida
The U.S. 11th Circuit
Court of Appeals recently ruled on Borgner vs. Brooks II. The court decided
to uphold Florida's restriction of dentists advertising credentials awarded
by the American Academy of Implant Dentistry. The advertisements must include
disclaimers that neither the American Dental Association nor the Florida Board
of Dentistry recognizes the AAID, and that neither the ADA nor the Board recognize
implant dentistry as a specialty area.
Florida dentists who wish to portray themselves as specialists in a non-approved
specialty must incorporate these disclaimers, in a distinguishable way, in any
announcement, solicitation or advertisement:
(Name of announced area of dental practice) is not recognized as a specialty area by the American Dental Association or the Florida Board of Dentistry.
(Name of referenced organization) is not recognized as a bona fide specialty accrediting organization by the American Dental Association or the Florida Board of Dentistry.
The AAID Attacks The Dental Implant Homepage
Well, this month (June, 2001) I finally received a letter from the General Council of the American Academy of Implant Dentistry (AAID) siting that the contents of this web site regarding the AAID and Implantologists are "misleading, false and defamatory". The letter specifically cited this page, my FAQ and my comments in Beware of Deceptive Advertising. Interestingly enough, I also recently received a letter from Carl Misch and the American Board of Oral Implantology/Implant Dentistry (ABOI) urging me to become certified as a Diplomate of the ABOI and siting recent California and Florida rulings on this "credential". It is obvious to me that the AAID and the associated ABOI are making a huge move to enroll as many dentists as possible into this program in order to establish a feeling that implantology is really a specialty of dentistry. I would hope that the readers of this web site will always understand that there is a vast difference between a legitimate specialty in dentistry and an organization which is merely trying to carve out a niche in terms of patient care.
I regard the recent communications from the general council of the AAID as an attempt to censor this site and I just want to inform everyone who visits this site (There are 6,000 of you per week) that I will not yield to this pressure. I still believe freedom of speech trumps the aspirations of an organization which, in my opinion, confuses the real issues and promotes a situation which might not be in the best interests of the profession and the patient population.
Shameless Self-Promotion
I went to the 3I meeting this weekend (January 26-27, 2001) entitled "Pursuing Conclusive answers to Clinical Questions", and I must tell you how disappointed I was in the shameless self promotion of the the meeting. All of the lectures were designed to promote 3I products and it wouldn't have been so bad had the speakers really shown some serious advantages to the products, but what we saw was many conclusions drawn on absolutely false assumptions.
I have been to many 3I meeting over the years, and I have always enjoyed them and found the information quite useful. I'm not sure whether this departure is a result of the new ownership of the company or just an aggressive need to get a larger share of the market. It seemed like there were about a thousand attendees to this meeting, many from Europe. I talked to some of them and the awareness of this self promotion attitude was very evident to all of them.
It has not been unusual for manufacturers to sponsor meetings and bring in good speakers who use their products. In the past, this has not been a problem because you could always take what is said with a grain of salt. In this case however, the level of bias was so high that it made the meeting absolutely useless.
Carpe
Diem
Recent events have inspired me to think about two giants in the dental Implant
field, Richard Lazarra and Gerald Niznick. I am pretty sure that when both of
these men graduated their respective dental schools, neither one of them expected
to become entrepreneurs. They both went on to pursue PG programs in dental specialty
areas, Jerry Niznick in Prosthodontics and Rich Lazarra in Perio and had they
stopped there, I am sure that both of them would have had wonderful careers
in dentistry and would look back on their accomplishments with great pride.
However, both of them through foresight and understanding of the needs of the
profession went way beyond their expectations. They both recognized the importance
of another man's discovery and they proceeded to take the initial discoveries
to a much higher level of clinical understanding. Dr. P. I. Brånemark made the
initial discoveries and did the ground work to make dental implantology a reality.
Drs. Niznick and Lazarra took that discovery to its potential and made dental
implantology available to the masses.
Both Dr. Niznick and Dr. Lazarra showed tremendous initiative and innovation
in the development of products that met the demands of the patients and the
profession. They never stopped looking for better ways to design implants and
components to help people who were missing teeth. Along the way, they both made
tremendous amounts of money and they both were very generous in supporting dentistry,
dental education and humanity.
Now that there companies have been sold, I hope that they both stay as prominent
as they have been in dentistry. A recent communication from Jerry Niznick tells
me he will continue to contribute and innovate and my knowledge of Rich Lazarra
would tell me that he to will continue to be a contributor. I just want them
to know that all of dentistry salutes them and thanks them for their contributions.

The
following is a copy of a letter sent out last year to the Implantology and the
Prosthodontists mailing lists:
I'm posting this on the Implantology list as well as the Prosthodontists list
because I think both groups would be interested...
Two weeks ago, at the ACP meeting in New York, I had the pleasure of sitting
in on a presentation given by Dr. Clark Stanford. The title of the lecture was
"Evidence Based Assessments of Osseointegration and the Proliferation of Implant
Systems". For those of you who do not know Dr. Stanford, he is currently an
Associate Professor in the Dow Institute for Dental research and in the Department
of Prosthodontics, College of Dentistry, University of Iowa. He also holds an
appointment in the department of Orthopedic Surgery, College of Medicine, University
of Iowa. Dr. Stanford received his BS, DDS, Certificate in Prosthodontics and
Ph.D. (Cell Biology) from the University of Iowa and he has been on the faculty
there since 1992. He also maintains an intramural clinical prosthodontic practice
within the College of Dentistry.
In light of the ongoing discussion about faster loading of dental implants as
advocated by various manufacturers and individuals due to various coatings and
micro surfaces, I posed the following to Dr. Stanford:
"At any rate, I have been disturbed with the number of claims that are coming
out from different companies about how much better their implant will
integrate than others. There is obviously a race on to see which system will
emerge as the fastest and most predictable of them all.
My personal opinion from my own clinical work and from reading the
literature is that there is no real evidence at this time that anything
works any better than anything else with the exception of HA coatings which,
of course, open up other areas of concern. I am especially irritated by the
companies such as 3I and Strauman who claim that their implants can be
loaded within 6 weeks. I don't doubt that under specific conditions that
this is doable, but it can be achieved with any plain vanilla implant as
well."
He responded with the following,
"You've hit the implant head on the nail with your comments about "faster,
better, quicker." What is amusing is the concern and care expressed 10-15
years ago about the healing process and time needed to now where the rules
seem to be "violable" without care (and these comments or "rumor" are often
based on anecdotal cases. One of my greatest concerns is with
extrapolations made to general implant care based on a few rather "ideal"
implant scenarios (e.g., fixtures in the ant mandible of Type II bone and
15-17mm fixtures) being proposed as the standard of care for immediate
loading (at stage I) and therefore this can be offered to all of our
patients as the treatment modality of choice. I fear the dikes will have to
start to break again (I.e., increased failures) for people to be more
cautious again. This is the same argument I have with large multicenter
studies (which I'm also involved in) in which the conclusion (success rates,
etc.) are generalized to populations or clinical situations which were not
represented in the study populations and in which the results do not
directly apply. Case in point is studies which profess to look at type IV
bone situations but in which type IV bone only represents 10% or so of the
fixtures at risk. In terms of your comments about surface coating, I agree
about the Ca/PO coating history although there is interesting working coming
out of Europe with magnetron sputter coating (<1nm). I also believe bulk
roughening procedures (e.g., it blasting or etching) does play a role in
increasing surface area an issue especially with type IV bone) but that the
surface per se, especially in high risk situations does not change the
healing rate of the body. Rather it give more potential area that the body
can heal against."
Some people on the Implantology List have been a little PO'd because I have
objected very strenuously to input about diagnosis and treatment planning from
dental implant companies, Dental Hygienists who work for dental implant companies,
Laboratory Technicians and others who do not place and restore dental implants.
I would certainly prefer to go to someone like Dr. Stanford, a Prosthodontist
with a degree in Cell Biology, to discuss this type of information over the
other people I mentioned. I don't mind discussing the oral hygiene status of
one of my patients with my hygienist and I certainly do not mind discussing
many aspects of dental technology with my lab techs... In case a lot of you
haven't noticed, most of the general Dental population gets a great deal of
their information from dental implant companies and their representatives and
dental laboratory technicians. There is a lab here in Florida that sends out
a tech to the dental offices with instrumentation to "help" dentists restore
implants... This is wrong and the fact that it is tolerated as a matter of course
only undermines our professionalism.
If you want to get the real answers, ask the real researchers and the real specialists.
Dr. Gordon J. Christensen's Comments on Dental Implant Therapy
Dr. Christensen is a Prosthodontist
and Director of CRA. CRA (Clinical Research
Associates) is a nonprofit organization dedicated to serving dentists by evaluating
dental materials, devices and concepts for efficacy and clinical usefulness.
Findings are reported as rapidly as possible in written and oral forms, including
the monthly CRA Newsletter. I had the pleasure of attending one of his CRA Dentistry
Updates in Fort Lauderdale, Florida on Friday February 4, 2000. I was very interested
in what he had to say about dental implants and I will attempt to summarize
his comments below:
The title of this section of his presentation was BAR AND CLIP RETAINED PROSTHESES.
He stated that 5% of General
Practitioners place implants and 30% of Prosthodontists place implants. He would
like to see 90% of GPs do implant surgery.
The average fee for a full lower denture is $800 and 90% of lower denture wearers
hate their full lower denture.
The average fee for 2 implants and new denture is $3300.00. The average fee
for a Bar and clip implant overdenture is $6900.00. This fee breaks down as
follows:
$800 for the Denture
$200 for the clips
$4400 for four implants ($1100 each)
$1500.00 for the Bar
Dr. Christensen feels that the clipbar overdenture is the best service available
for treating mandibular edentulism. He really likes this and says that this
is what he would want in his mouth.... Hates fixed-detachable because it is
very hard to clean and very expensive...
He teaches GPs implant dentistry in a two and a four day course. He recommends
the following:
Attachments from Attachments
International. He likes very long distal extensions on his bars and he keeps
the bars as close to the soft tissue as possible. He likes lots of clips and
uses spacers to establish resilience. He uses a tear drop shaped bar with metal
clips. For two attachment denture he prefers a small ball and O-ring attachment....
Dr. Christensen also talked about the IMTEC transitional implants (SENDAX).
Recommends them for long term use...
It looks like he is raising a flap to insert them..... After he spoke, I went
up and asked him if he would consider the SENDAX transitional implants used
with a no-flap approach. He said that would be fine. I asked him if he would
then consider this to be a NON-SURGICAL IMPLANT? He said "YES".
Kentucky Oral Surgeons Petition State Board to Stop Periodontists from Extracting Teeth and Placing Dental Implants
This could very easily go under the "Now I've Seen It ALL" category, but as amazing as it sounds, the President of the Kentucky Society of Oral & Maxillofacial Surgeons has sent a letter to the Kentucky State Board of Dentistry requesting, "The Board of Dentistry make a ruling and render advice concerning the authorized scope of practice of persons licensed to practice the specialty of periodontics". They go on further to say, "KSOMS is concerned that periodontic specialists are increasingly performing dentoalveolar surgical procedures such as apicoectomies, and removal of teeth, exposure, bonding and ligation of teeth and dental implantology, and are holding themselves out to the public as specialists in some of these procedures. These procedures appear to be outside the accepted scope of practice of periodontics".
Next, we'll have the prosthodontists petitioning to have general dentists banned from providing full crown restorations for their patients.... (--------). If you are interested, you can read the full text of this letter.
JADA does it again..

Check out the September 1999 issue where the venerable journal of the American Dental Association published an article on how to retouch your radiographs to bilk the insurance companies... I'm not kidding!!!
Poly-Grip and the Journal of Prosthodontics

As long as I have been in dentistry, I have felt that denture adhesive represents a failure in dentistry. It's like when we can't do anything else for a patient who is missing their teeth and uncomfortable with complete dentures, we hand them a tube of denture adhesive and send them on their way. To tell you the truth, I have always felt uncomfortable receiving the denture adhesive samples that some companies hand out to us dentists so I usually chuck them!
So perhaps this will give you a little idea of why I am so upset when I pick up a recent copy of the Journal of Prosthodontics, the official journal of the American College of Prosthodontists, and turn to a full page add for Poly-Grip. I don't think this ad should be in this journal. Maybe it might be more appropriate in the ADA Journal, but not in the journal that represents the specialty that is supposed to allow patients to live without the indignity of denture adhesives.
Today, with dental implants and all of the techniques that we Prosthodontists have at our disposal, there should be no need for denture adhesives. But the sad fact is, denture adhesive is big business and big business does what it has to do to promote itself. Over the years, I have seen an insidious creep of "support" for prosthodontics by companies that make their major living selling denture adhesive. I think it is wrong and I do hope that some of you agree with me. If you do, please send an E-mail to The American College of Prosthodontists at acp@prostnodontics.org and express your feelings. SRD
ADA Advetorials
Sub-Periosteal Implants and other things that go Bump in the night....
I recently was asked to speak at the American Academy of Implant Dentistry (AAID) and I found it quite an interesting experience. In the introductory remarks on the first day, the speaker claimed that Periodontists were not really trained to do implants and therefor should not do them. You have to understand that this organization, the AAID is composed primarily of general practitioners who do implants and that there are very few specialists, especially Periodontists, associated with the organization. This is a group that feels that continuing education in a given area is equivalent to Specialty training in a three or four year academic program. This just ain't so guys...
On another day, the speaker compared the AAID to the Academy of Osseointegration (AO) as the academy of "Antibiotics" compared to the academy of "Penicillin". The feeling of the AAID is that because they have a multi-modal approach which includes root form endosseous implants, sub periosteal implants and anything else that you can sink into or around bone, they are superior to a dentists organization that only endorses root form endosseous implants. Their "Board Certification" procedures require demonstration of this multi-modal approach. Forget about all of the research available today that shows there are severe limitations to the sub-periosteal implant techniques and the fact that root form endosseous implants have a much higher success rate!
I have included two slides here to show something that I have often seen with dentists who do a lot of sub-periosteal implants: FAILURE! The first slide shows a five year old case where the implants are failing. The second slide shows the patient after she paid thousands of dollars to have the failing sub-periosteal implants removed. Now she is a candidate for normal root form implants which not only have a much higher success rate but more importantly do not fail with the causation of excessive damage and expense to the patient.


The really sad issue here is that the AAID has just won the right to present their credentials to the public in the State of Florida. That means that these individuals can advertise that they are Board Certified in implant dentistry the same way someone might be Board Certified in Periodontics or oral surgery. We know that these two credentials are not in any way equivalent and the entire concept is misleading to the public.

Biocare discovers prepable abutments and cemented dental implant restorations...
