SOME OF OUR READER'S COMMENTS
1988
GTM, Professor, Univ. of Illinois, Chicago, IL: "I am very much impressed with your material 'Adhesion and its Ten Commandments'."
1990
RM, Norfolk, VA: "I enjoy reading your essays in "Phoenix" and find them to be refreshing intelligent. I particularly like your debunking of mechanical myths that persist in our profession, propagated by supply companies and clinicians who lack a basic engineering background... There are still a lot of false idols that need smashing."
1991
SBF, Professor, U. of Pennsylvania, Philadelphia, PA: "I am enclo-sing the copy coupon regarding additional quarterly newsletters as they become available. I have used these for both classes so that our residents may get a better perspective on the metallurgy and other characteristics of our orthodontic appliances as you have described them in your quarterly letters. We appreciate this service and are looking forward to forth-coming issues."
1992
BCJ, Professor, U. of Connecticut, Farmington, CT: "I agree with your conclusion that brackets, using present techniques, cannot be overly reduced in mesial distal width for many reasons including friction."
BM, Professor, West Virginia Univ., Morgantown, WV: "Your quarterly 'Phoenix without Ashes', has been brought to my attention by Dr. Kitchen. I found the recent article concerning corrosion to be useful for demonstrating the problems with gold-plating oral appliances."
LAN, Coral Gables, FL: "Thank you for your excellent newsletter. Please continue to send your informative, educational newsletter to our office."
RH, Professor, Univ. of Alabama, Birmingham: "I have read some of the articles in your publication and have enjoyed reading them."
KG, Chairman, T-3J Unit Committee, Du Pont de Nemours, Beaumont, TX: "I read with interest your September 1992 newsletter regarding microbiological attack of orthodontic appliance adhesives and alloys respectively. I fully agree that there appears to be parallels between MIC (Note: Microbiologically Influenced Corrosion) in industry and MIC in the mouth. This infor-mation would be of interest to the NACE (National Association of Corrosion Engineers) community."
KJS, Lakewood, CO: "Keep it comin'! It's great to have a medium to cut through the ad hype !"
RM, Professor, Univ. of Inns-bruck, Austria: "I was a very inte-rested reader of your 'Phoenix', one of my favorite sources of information on bracket technology... I would like to invite you to give a course..."

LJL, Coos Bay, OR: "'Phoenix' has had some really good ideas and discussions in the past; keep up the good work."
SBF, Professor, Univ. of Pennsylvania, Philadelphia, PA: "I want to thank you again for sending your periodical to our students at Penn. It gives a different perspective than the manufacturers would like and exemplifies the old saying that "there are two sides to every question."
1993
RPE, Professor, Univ. of Stellenbosh, S. Africa: "I have enjoyed receiving your quarterly publication 'Phoenix' "...
STM, Professor, Univ. of Minnesota, Minneapolis, MN: "Good luck in your continued efforts to make some sense of all the confusion between mechanics and mytology."

GTM, Professor, U. of Illinois, Chicago., IL: "I found your article on magnets very interesting and I think the materials makes excellent background for anybody about to undertake their use. I certainly learned a good deal and have already read a lot on the subject."
PWR, Professor, Univ. of N. Carolina: "Thanks for sending me the material on the straight wire appliance that you plan to publish. I find it an entirely appropriate reaction to the tremendous overstatements made by the proponents of the appliances..."
HJL, Walnut Creek, CA: "I always enjoy your informative articles in your newsletter. As the director of a study group of 25 dentists who meet monthly, I am always looking for informative speakers. The metallurgy and chemistry of orthodontic appliances is a subject we've never had addressed to us."
SBF, Professor, U. of Pennsylvania, Philadelphia, PA: "I was pleased to receive the latest issue of 'Phoenix without Ashes' and enjoyed reading your review of the early days. You've certainly done your home work!"
1994
BD, La Mesa, CA: "I really enjoy your newsletter. I always read it and it is very interesting".
SBF, Professor, U. of Pennsylvania, Philadephia, PA: "While I have only spoken with a few faculty with engineering degrees from other departments, my impression is that they are involved with research in relatively narrow areas and do not express (to me, at least) the breadth of knowledge reflected in your discussions about the alloys we use".
CGJ, Editor, Provo, UT: "From contacts with my orthodontists friends, and reading your newsletter, I am impressed with what you have accomplished, and congratulate you for your efforts. Your and our activities appear to have many similarities".

AWA, Oak Brook, IL: "I wanted to take a moment to thank you for developing your newsletter 'Phoenix' and now 'Insider'... I feel your news letter can provide an invaluable service to the orthodontic profession. With manufacturers interested in selling their products, not in testing them, and the journals willingness in spreading the disinformation about these products, an alternative source of information is needed, and I feel your newsletter would be an excellent choice. Thank you and keep the good work."
HJK, Sydney, Australia: "As a son of a metallurgist who commanded international respect during his wor-king years, I can relate to many of the articles that you publish. The physical properties of the alloys that we use, the quality control (or lack of) and the seemingly cavalier approach of many companies when selling what appear to be untested products onto the market are all things to which I can relate. In my view, your publication goes a long way to provide information that seems to be lacking in any other form of professional publication."
CA, Editor, Barcelona, Spain: "I have received several issues of your 'Phoenix without Ashes' and lately the December issue of the 'Orthodontic Materials Insider'. I am very interested in receiving it also in the future... I would like to publish in our Journal one or more articles on brackets, and I think that your work can be very inte-resting for our readers.

SBF, Professor, Univ. of Pennsylvania, Philadephia, PA: "Recently, I have been musing about these contributions as well as your publications in American J. Orthod. and wonder if you've ever considered either writing a book on your own, or else finding a knowledgeable kindred soul to collaborate."

Would we be considered the Rosa Parks of recycling? |
|
_____“The woman who changed a nation”, “the mother of civil rights movement”, Rosa Parks, made history December 1955 when she refused to give up her seat to a white passenger. She was arrested, jailed and tried. As a result of the public’s opinion, her stand against racism became a symbol for equality. Her resistance to oppression was admired and prized: in 1984, she received the Eleanor Roosevelt prize and in 1995, the Parks Foundation was formed. Furthermore, a school and a boulevard were renamed in her honor, and a monument is planned.
_____Her story might well resemble ours. We stand for the practitioner’s right to reuse whatever he believes fit from his armamentarium, for the right to recycle as opposed to dispose, as manufacturers would enjoy. As a result of our position, we have been slandered, threatened, brought to a law suit. While we are still far from being encouraged, federal agencies and professional organizations have started, after long and tedious debates, to accept the clinicians’ right to reuse his tools and ours to continue what we were doing for twenty years. As the law operates by principles and not by specific instances, we have succeeded in enlar-ging the opportunities for recycling. In older times, many devices were reused in the absence and of appropriate means for decontamination: today, when the knowledges are deeper, manufacturers would like to have them wasted to increase their profits.
_____Our research has accomplished noteworthy contributions to protect the consumer. New attachments are analyzed and their defects such as corrosion susceptibility, mechanical weakness and shoddy workmanship are denounced. Do-it-yourself testing methods encompassing attachments corrosion susceptibility, strength, friction and impact resistance were and are devised. Overextended concepts within the preadjusted brackets or the prescriptions‘ accuracy were exposed. Microorganisms were found to feed on adhesives and polyurethane elastomers to be cytotoxic. These results were published not only in this newsletter, but in over forty papers and innumerable conferences throughout the world, from India to Guatemala to Egypt.
Our beginnings.
___The first comercial recycling of an orthodontic attachment was performed mid 70's as an attempt to recover attachments made of the best steels remained unscathed after the orthodontic treatment. As a marked decrease in mechanical strength and corrosion resistance was found to follow the charring of the adhesive, a new process was used: the adhesive’s dissolution. The results were so good, that we followed in 1978 with the first resale of used, reconditioned attachments. More and more practitioners realized that what they have done all along with the stainless steel armamentarium can be done also with their brackets, tubes, bands and buttons, once these are pro-perly cleaned, decontaminated, checked and sorted. Within ten years, the proportion of the practitioners who reused their attachments was such that several manufacturers started a sustained vilifying campaign in the media and through their sales representatives. Both in the US and Europe, the Orthodontic Manufacturers Association (OMA) and the European Confederation of Medical Devices Associations (EUCOMED) have spent considerable resources to curb the trend. Many thousands of pamphlets were distributed and conferences about the liabilities incurred were held by lawyers. In 1990, according to the American Association of Orthodontists (AAO), 30% of its members were willing to report to their association that they use recycled brackets1. It is easy to assume that many didn’t want to report following an NBC’s-TV “Fight Back” broadcast directed against the practice.
As all these efforts didn’t seem to affect the progress of recycling, one of the twelve members of OMA, Ormco, sued in 1995 in federal court in Los Angeles, the largest and best known recycler and the new industry’s lightning rod, Ortho-Cycle Company, for reusing single-use items and infringing their rights on US Patent 4,415,330’83, "Orthodontic bracket assembly".
The facts.
____Both Ormco’s complaint, as well as a study from the University of Iowa which was misquoted and distributed by the manufacturers to thousands of practitioners, raised problems related to the recycling of the orthodontic attachments. In a letter dated January 1997 to its membership regarding the use of recycled attachments, AAO showed that this is a matter for each orthodontist to consider: ”Decisions regarding diagnosis, treatment, orthodontic appliances used and other similar clinical decisions are best made by individual orthodontists in consultation with their patient“. In a February 1997 update, the Ontario Dental Association has shown that a similar position was taken by Health Canada1, which represents the Canadian government. Their survey shows:
a. "It is not uncommon for certain dental and medical devices to be reused, provided appropriate infection control procedures are followed. For instance, dental handpieces and heart pacemakers are reused...
b. Scientific evidence indicates that there is no clinically significant difference in the effectiveness of recycled orthodontic brackets vs. new materials...
c. There is no evidence that any patient has been injured as a result of wearing recycled orthodontic brackets...
d. There is no evidence that recycled orthodontic brackets pose a public health risk...
e. Depending on the type of brackets recycled, there may be an insignificant reduction in bracket strength. However, studies have also shown that the same factors can produce an increase in bracket strength...”
The trial.
____Facing the charge, Ortho-Cycle presented two counterclaims: one for “patent misuse” and the other for antitrust violations (the Sherman Act). As a result, the case was withdrawn by the plaintiff just before the date of the sche-duled trial, April 1996.
Post trial events.
____August 1996, a misquoted University of Iowa study on recycling was sent to thousands of practitioners by Dr. Kesling from TP Orthodontics and OMA. In this inter-pretation, the bracket slots were shown to be significantly enlarged during recycling. We analyzed the data, showing the bad faith behind the interpretation2.
____November 1996, we invited a crew from the “Dateline” program (NBC-TV) to closely observe what we are doing. After filming everything from 9.00 to 6.00, we were told that the program will be aired within two or three months: it never happened.
____July 1997 we were investigated for some two weeks by FDA, which could not find any objectionable handling of the attachments.
____September 1997, in a complaint in a Richmond, VA, court, Dr. Donald M. Fox, a diplomate of the American Board of Orthodontics, has alleged that the brackets he purchased from TP Orthodontics were faulty and led to the rebracing of 225 patients3. During the suit, the following were stated under oath by Dr. P. C. Kesling in regard to slot tolerance: "I don't think I would know the difference if I had a .0025 or a .005" difference. Not significantly different".
____We would like to remind our readers that in the OMA letter to clinicians (August 1996)2, a variance of .0024" and .0051", as found by the Iowa University study in some recycled brackets, was considered a significant change, which impairs dramatically bracket performance. Coincidentally, Dr. Kesling from TP Orthodontics is also OMA’s president.
The redemption.
____In a sequence of four notes dedicated to the importance of the materials orthodontist use, Ortho-Cycle’s contribution was prized by no less than five luminaries in the field4. Today, we have not yet really felt the burden of being submerged by our own waste. Tomorrow, for sure, drastic measures will be taken not only against those who pollute, but also against those who encourage this. It is true, orthodontic attachments are insignificant in volume and the amount of heavy metals released when, in the absence of oxygen, the stainless steel disintegrates, is small. The principle stands, however. If the manufacturers’ efforts for waste and against recycling is not curbed in time, it will make the life of future generations wretched. Obser-ving the speed with which attitudes change, we may be well alive to be honored for our efforts and pains to renew, as our newsletter headline states, not only tools, but also habits.

IS SOME ORTHODONTISTS’ THINKING “ANTIQUATED” ? |
|
|
____For ten years, we have steadily written in this newsletter articles commenting on the biomaterials and devices orthodontists use, occasionally receiving their unsoliciterd thoughts. With the occasion of our jubilee, however, we will use the Roman custom ( Saturnalia, once year, also in mid-December) to reverse this by criticizing some of those we attempt to serve.
____Some seven years ago, we started to wonder why many clinicians, when asked about their tools, didn’t show any uneasiness when claiming that “only their girls know that."1 Moreover, although a newsletter entirely dedicated to this topic was offered them for free, not many showed interest initially.
This attitude has old roots. Both Romans and Greeks believed that technology was degrading, being a business fit only for slaves, and no intelligent thinking man should bother with it. Archimedes even refused to write a book on engineering, giving as reason that everything that makes life easier was ignoble and vulgar. Greeks used mathematics only as a mental exercise2. The ancients’ position toward inventors and materials was no different: the Egyptians and the Mesopotamians did not even record the names of their inventors. While Greeks recorded their names, they didn’t try to apply their sophisticated inventions for the everyday endeavors and did not pay attention to the materials they used. As a result, their machines never worked properly. Romans did somewhat better: they did not invent new technologies, but copied, applied and spread other people’s mechanical devices throughout their empire. Their ideas of medicine were extremely unscientific, but surviving surgical instruments, made of rather improper materials, were extremely well designed for the work. Leaving the activities they didn’t like to their underlings, when later on they switched to the nice life, led to their defeat2.
____In contrast, early orthodontists were quite interested in technology and materials. Thus, E.H. Angle was an accomplished metallurgist, as he prepared German silver “in varying proportions according to the use for which it was intended."3 His followers had their discussions directed toward "plain molar bands versus screw bands, German silver arches versus gold arches, different types of band materials and ligatures."4
____Today, despite the fact that orthodontic dental materials are part of the accreditation standards for graduate education in orthodontics5, only a few universities teach them. The flood of products with which clinicians are daily assaulted probably makes them feel secure. The result has been summarized as follows by the technical leader of a major manufacturer (Dentaurum): “The orthodontist lacks specific knowledge in material science which condemns him to hesitation. In such instances, he relies upon his empiric experience, giving up the furthering of his knowledge.... For the manufacturer, it is always amazing to see how noncritical can the orthodontist be6...”
