Increased Demand for CBCT

During the past months the dental market has been buzzing about CBCT Scanners and Ceph images. This is mainly due to the increased demand for CBCT scanners, and the superior imaging quality yet lower radiation doses it delivers. Initially, this new technology was only used to evaluate jaw bones (for implants or surgery), but quickly advanced to panoramic and Cephalometric imaging capabilitiesCBCT


What is CBCT (Cone Beam Computed Tomography Scanners)?

A medical imaging technique where the x-rays are divergent, forming a cone. The 3D technology and panoramic imaging enables very high resolution pictures, yet through low radiation. Cone-Beam Computed Tomography (CBCT) is a new technology which is dedicated to imaging change from a two dimensional to a three dimensional capability and has created a revolution as it enables substantial improvement in operative and surgical procedures.
Some of the advantages of this new technology include: more rapid acquisition of data, shorter examination time, reduced image distortion, and best of all – one quarter to one fifth of the price of the standard CT machine. In addition, during the last decade manufacturers were able to produce small enough machines to be used inside dentals offices.

According to recently conducted research (*Transparency Market Research), the Global cone beam computed Tomography (CBCT) market expected to reach US$ 960.8 million in 2023. This demonstrates a clear high demand from clinics, and provides an increased incentive for further technology development and improvements. There are currently various leading manufacturers, but overall the demand for CBCT is sometimes said difficult to fulfill.

What about radiation??

Zero x-rays carry zero radiation! But, that’s almost impossible when treating patients these days. Saying that, the average radiation exposure for individual, panoramic and Cephalometric images have decreased. This is mainly due to improved protocol and procedures established for both clinicians and patients. It is also due to advancements in technological solutions such as the CBCT scanners. Comparison with patient dose reported for maxillofacial imaging by conventional CT (approximately 2000 mSv) indicates that CBCT provides **substantial dose reductions of between 98.5% and 76.2%.

What are common uses for Dental Cone-Beam CT?

The technology is normally used for treatment planning of orthodontic issues. These include surgical teeth implantation planning and placement, disorders diagnostics, tumor detection and treatments, pain locations, reconstructive surgery, and Cephalometric analysis.
Depending on the procedure type the patient is normally required by the practitioner to sit in an exam chair, while the scanner is used. Afterwards, once the results are ready, they will be discussed with the patient and proceed to the proper treatment.

Regardless of the technology used at dental clinics, CephX still provides the prime analysis and reports with the highest accuracy and substantially lower processing time. CephX is a fully-featured cloud system, where you can create patient records, upload X-Ray and profile photos, and be sure you can always access past records, photos and analyses as they are stored, secured and backed-up daily!

Interview with Dr. Greenfield – Non extraction technique

Dr. Greenfield is the author of “Nonextraction Orthodontics, 98.5% Nonextraction Therapy using Coordinated Arch Development®“, a textbook that has been published in four different languages, and is now in its 2nd edition, with over 1,100 pages and 7,000 images.

During the making of his textbook Dr. Greenfield made extensive use of services to get unbiased Cephalometric analyses, and through that we came to learn about his 98.5% nonextraction treatment philosophy entitled; “Coordinated Arch Development®.”


Dr. Greenfield was invited to present his philosophy at the 1996, 2003, 2004 and 2005 scientific sessions of the American Association of Orthodontics, and was asked to defend his Nonextraction approach at numerous sessions, including:

  • The 1992 and 2002 College of Diplomates of the American Board of Orthodontics annual sessions
  • The 1993 Southern Association of Orthodontists’ annual session
  • The 1998 Northeastern Society of Orthodontists’ annual meeting
  • The 1999 American Academy of Pediatric Dentistry annual session
  • The 2001 Japanese Orthodontic Society Annual session.



Let’s start with your background information

I am a graduate with honors from Howard University College of Dentistry in 1971.  After receiving my Master of Science in Orthodontics from Boston University in 1973, I continued as a Clinical Instructor until 1976.  In 1984 I became a Diplomate of the American Board of Orthodontics and was invited to exhibit my board cases at the A.A.O. meeting that same year.

How and when did you develop your NON-extraction technique?

“Coordinated Arch Development®“ is a nonextraction philosophy more than a technique.   Its roots were formed in the early 1940’s from the work of my mentor Dr. Norman Cetlin, arguably one of the greatest orthodontic clinicians in the modern era.  The Tweed extraction philosophy was very popular at the time and consequently Cetlin’s early efforts were overshadowed.   In the 1970’s and 1980’s, long term nonextraction cases were exhibited at the AAO meetings which aroused great interest in the philosophy. Cases 25 years out of retention were also submitted to the University of Michigan for evaluation of the technique’s long term stability.

Please explain “Coordinated Arch Development®” philosophy

Achieving long term stability requires controlled upper and lower 1st molar movements, simultaneously, in all three planes.  Light continuous forces of similar magnitude are utilized to “coordinate” these movements.  The final orientation of the molars creates occlusal forces through the long axes with the absence of deflective contacts during function.  The molars are placed well within cancellous bone and the “neutral zone” to enhance their compatibility with the periodontium and soft tissue envelope.  The resultant position of the anterior segment provides proper incisal guidance and maximizes facial and dental aesthetics.nextortho-sample1

What has changed in the industry since the book was written?

The pendulum has definitely swung towards a nonextraction treatment approach the last several years.   People want a full radiant smile rather than seeing dark corridors at the corners of a smile.   However, there is high quality nonextraction treatment and there is quick nonextraction treatment.   The new generation of orthodontists must lean towards quality in this delicate balance.   The Doctor must remember that the treatment decisions they make today will impact the patient’s health for the rest of their life.   Throughout the Textbook, the principles for attaining long term stability for their patients are explained in vivid detail, and must never be compromised for the sake of “efficiency.”

What can you tell us about the book writing process?

The writing of the Textbook took approximately 4 years.   Without the encouragement of my wife, the project would never have been completed.   She typed and proof read the entire manuscript while I compiled long term records on my patients.  In fact, my youngest daughter whose a graphic artist, designed the cover – it truly was a family effort.   I had 3 contributing editors write 3 chapters in the textbook, and CephX , under the expert direction of Danny Abraham, traced every cephalometric x-ray in the textbook.  CephX unbiased data not only made my job easier, but it contributed greatly to the success of the publication.   We also included 10 cases  from my study club in Japan.   I specifically chose Japanese cases since they are considered to be among the most difficult nonextraction cases in the world.  It was my way of confirming the versatility of this philosophy no matter how difficult the case.nextortho

When and where was the book distributed thus far?

The textbook has been published in four different languages, and is distributed throughout the world. It is available in hard copy (Amazon), and in digital (Downloadable) format.  The information contained in the Textbook is NOT available anywhere else, so Doctors that have purchased the Textbook are very appreciative of its content.  I constantly receive hundreds of emails from Doctors around the world thanking me for sharing this information – it has prevented the unnecessary extraction of teeth in thousands of children and adults.

My ultimate goal is to create optimum LONG TERM function and radiant smiles for our patients worldwide.

Can you share with us feedback you received about it?

The feedback has been extremely positive – beyond my wildest imagination.  Doctors have emailed me thousands of photos of their cases treated successfully with the information contained within the textbook.   Many Doctors wished they had this knowledge earlier in their career.  In fact, my Japanese study club recently won 1st place for their case presentation at the American Association of Orthodontists Annual session.

Do you plan to publish a follow up book to extend the technique?

The textbook is now in its 2nd edition and still very popular.   The Chinese publication has just been released in December, 2015.

Instead of publishing a 3rd edition, we have now expanded our FREE WEBSITE, NEXTORTHO.COM to include VIDEOS of all the techniques in the textbook, and 100 nonextraction cases illustrated in vivid detail in our “library of cases.”  By making the website FREE, we have made the “Coordinated Arch Development®” nonextraction philosophy accessible to students and clinicians in every country.   This will expedite my goal of preventing unnecessary extractions in children worldwide.

How do you feel about CephX – how relevant is the online tool for the industry – what is the added value you see in Cephx to the industry

The value of CephX to me as a clinician, author and researcher is extremely valuable for different reasons.   First, it removes all bias from my cephalometric measurements.   This is very important in the minds of Doctors who purchase my Textbook.  If I traced the X-ray, they may be concerned that the measurements were skewed in my favor.

The tracings are performed by a well-trained 3rd party who does it all day long.   Thus the quality of the tracings and measurements are consistently excellent.   Our diagnoses & treatment plans are certainly enhanced by their quality & consistency.

CephX has all the popular cephalometric analyses on their website.   Therefore, the Doctor can refer to any of the analyses for a specific measurement to aid his diagnosis – how important is that!   In fact, Doctors who purchased my textbook were allowed to contact CephX to gain access to any of my case measurements if they wanted to view their favorite analysis online.   Finally, I cannot say enough about the excellent support of CephX I received for the past 15 years.   Anytime there was an issue, it was resolved the same day in a courteous and professional manner via email.

The Doctor does not have to train a staff member to perform this task, nor train another staff member should the original employee leave the office.   This is a real time saver in a busy office.

An author or researcher can focus on their research rather than worry about the accuracy of their tracings.   Placing this task in the hands of an expert improves the overall quality of the final product.

Finally, CephX may not have invented cephalometric tracing, but CephX certainly defines it.

How do patients choose their Orthodontist

Choosing an orthodontist carries great responsibility, as it has a very clear effect on a person’s aesthetics and health. The majority of orthodontic patients are children, leaving the responsibility on parents to choose the right caregiver and treatment type. This task is taken very seriously, and followed by weeks of research.

In this article, we have gathered the considerations that help parents and patients in general make up the final decision – who to choose as their Orthodontist.



Awareness and knowledge – of the treatment’s importance, orthodontist’s existence

Acknowledgement of orthodontists and their expertise is a vital first step. A patient must distinguish between a dentist’s role and an orthodontist’s role, while choosing whom to approach for treatment.

Awareness can be achieved through schools and teachers, family physicians, governmental programs and the media.

Need and Treatment Motivation

Today, aesthetics is very important. Our role models showcase perfect smiles in the media and we want our kids and ourselves to have that too. In addition, there is also the element of healthcare when it comes to orthodontics (sleep disorders, painful teeth misalignment).

The patient’s need has to be there, either from the healthcare or aesthetics sides, in order to turn to a specialist. If the problem isn’t troubling enough, the condition may be left untreated.

Credibility, References and Trust – of the Practice and Orthodontist

Education is part of the credibility Orthodontists have. Patients normally check their physician’s education, and certification, while also want to ensure they are a Board Certified. This demonstrates a higher commitment and dedication, given the standards requirements.

References (recommendations by experienced friends) are also an important element patients look for. Word-of-mouth, recommendation, testimonials all act as great reference for a patient. 

Technologically Equipped Clinic

People expect to receive leading treatment and to also fully understand it. The technology is available through improved software, larger screens, full images, laser innovations, advanced treatment materials, online Cephalometric analysis…etc. Orthodontists willing to ensure their clinic is staffed with leading technology and able to showcase it, are more likely to gain the customer.

Personal Connection

Trusting the doctor from an education perspective isn’t enough – if the personal connection isn’t there. Each patient looks for an assuring and easy-going caregiver, who is willing to listen to their questions, concerns and fears. Many doctors today may be very well educated, with lots of experience, but are less attentive to the emotional side of the treatment.  In situations as such, the patient will prefer to seek a different doctor, especially if there is a larger choice available nearby.

Affordable Costs & Payments

Affordable treatment prices are an important part of the patient’s decision making process, however it’s normally mentioned after overcoming the barriers mentioned earlier. It’s vital for the patient to first check their treatment type, and only then find out if they can afford it, considering various payment/finance options.

Many practices provide different payment terms, specifically since the actual orthodontic care is normally spread out through several months or even years.

Availability and Location

A treatment plan may be laid out over months and years, which is why patients tend to also choose their orthodontist according to the practice’s location and ease of travel.  Ensuring they can make the appointments, without loosing too much work or school days, due to traffic or parking issues is  important.


Every Orthodontist can play a major role in every single part of the listed items. Awareness creation, motivation, market education

  • Marketing plan – Maintain an online and social marketing plan, as that’s where most Patients start their research nowadays! Be sure to be listed on local/online directories, community organizations, healthcare programs.
  • Keep up to date – with new technologies, innovations, and treatment types. This will ensure your market competitiveness positioning.
  • Have your references, case studies, education easy to find. These can be publicized on the web, social media channels, and reviews by local/national magazines.
  • Make sure you choose a friendly staff with a welcoming and warm attitude.
  • Give back to the community – It’s always great to provide some pro-bono help. The community appreciates it, and increases your clinic’s credibility
  • Be ready for lots of questions, even if they sound repetitious or obvious.
  • Position your clinic in a good location, with good access to public transportation and parking.
