Join us for an inspiring
day exploring the ins and
outs of MIE.

Our teaching objective is to reduce
the fears and frustration clinicians encounter when making the commitment to extend
the usable life of endodontically-treated teeth. Upon finishing this course, attendees will better understand where and how to apply MIE principles in their everyday practices.

Until recently, we've been forced to balance conservation of tooth structure during RCT with irrigating efficacy. Due to the primitive irrigation tools we’ve had at our disposal, we cut big access and canal preparations out of necessity.  Now, equipped with stronger and more flexible tools and faced with the alternative of implant replacement, we ask ourselves, "How do we perform minimally-invasive endodontic procedures without losing our minds?" 

 As most of us on this path have found, MIE treatment restrictions can actually impact our short-term outcomes, an irony when our aspiration was to increase our long-term success rate. It is very clear that we need new concepts, tools, and techniques designed specifically for MIE. Conceptually, we need to better understand where the law of diminishing returns tells us that further dentin conservation is needlessly complex without increasing the longevity of teeth after RCT. Tool and Technique-wise it's been a difficult reboot for clinicians to cut, clean, and conefit MIE preparations.  

Drs. Buchanan and Maupin have been on this journey for a decade and have created this lecture to share the following:  

  • Designing MIE access cavities with CT-based planning
  • Executing MIE access with Dynamic Guidance  
  • MIE Instrumentation for Irrigation and Obturation 
  • MIE cleaning tools and strategies
      a. YSGG Laser - Laser Assisted Irrigation 
      b. Closed-System Negative-Pressure Positive Outflow
  • MIE Obturation Techniques
  • MIE Restoration

About The Instructors

Dr. L. Stephen Buchanan, DDS

Dr. L. Stephen Buchanan has been lecturing and teaching hands-on endodontic continuing education courses for 30 years, both in his state-of-the-art training facility in Santa Barbara, California, as well as in dental schools and meetings around the world.

He currently serves as a part-time faculty member in the endodontic departments at the University of the Pacific's Arthur Dugoni School of Dentistry and the University of California at Los Angeles.

Dr. Buchanan is nationally and internationally known as an expert in the research and development of new technology, instruments and techniques in Endodontics. He also maintains a private practice limited to Endodontics in Santa Barbara, California, and is a diplomate of the American Board of Endodontists and a fellow of the International and American College of Dentists.  

Dr. Charles Maupin, DDS 

Dr. Charles Maupin has been involved in endodontic education for the past five years. He has lectured nationally at various meetings, study clubs and dental schools currently serving as an adjunct professor at University of California, Los Angeles. 

Dr. Maupin has helped to modernize minimally invasive endodontics through dynamic navigation. He has also brought to light the efficiency, efficacy and safety of the use of a YSGG laser for endodontic irrigation leading to enhanced cleaning in a shorter amount of time. He maintains a private practice limited to endodontics and implants in Lubbock, Texas. 

 He is a diplomate of the American Board of Endodontics and a founding member of the International Academy of Endodontics.

My Journey into MIE by Dr. L. Stephen Buchanan

My journey into minimally-invasive endodontics (MIE) began in 1989, when a prosthodontist told me he wished endodontists could just "suck the pulp out of teeth without cutting any dentin". It's surprising to remember this now, but I was somewhat nonplussed by the idea as this was antithetical to the Schilder School who advocated for big access cavities and widely-cut coronal canal shapes–a necessity with the limited tools of the time. By 1996–because of the strength and flexibility of our endodontic tools–this was an obsolete concept of treatment, but clinicians continued to equate big RCT with excellence in endodontics, borne out by the many rotary file designs that cut large canal shapes that reflected that ignorance. By that time, I had been in practice for 16 years–long enough to see structural failures of my own cases, so when I designed the first variably-tapered files, I gave them a 1mm maximum flute diameter limitation.

The case (left) from 1998 shows typical shapes cut by GT and GTX Files–all three canals were finished with a 20-.06, irrigated with NaOCl for 40 mins, and filled with the Continuous Wave of Obturation Technique. Note the mid-mesial lateral canal and the loop off the distal primary canal.  

This tooth had a failing RCT that had been filled with Thermafil Obturators, but the carrier fill was not the etiology; this case failed because the canals were grossly undertreated. The mesial canals were 25.5mm long and the mesial root was narrow enough to be perforated by too much coronal enlargement, contra-indicating the use of most of the files available at that time. A 20-.06 rotary file with a 1mm MFD was used to cut the mesial preps, a 30-.08 w 1mm MFD was used in the distal canal. 

This is a recent case (left) cut with 20-.03 in the buccal canals and a 25-.05 in the palatal. Despite the tiny shapes, irrigation with a negative pressure multi-cannular system cleaned the entire length of the MB2 canal without placing a single file in it.  

These shapes were cut with a heat-treated MIE rotary shaping file set with .03 and .05 tapers. Note the large chip space and the razor-like cutting flutes provided by the unique 2-blade design.  

Meanwhile, Charles pushing the evelope by turning out incredible MIE RCT's like this case (left), showing excellent demonstration of lateral anatomy cleaned and filled despite the micro-shapes. He has refined the use of YSGG endo lasers to cavitate NaOCl in these shapes–one of the coolest things you will see at this presentation. 

Notice the grace and beauty of the minimally-instrumented premolar canal system. I reallly love how he flawlessly places post-RCT restorative materials deep in canal spaces without voids - he will share every detail of his post-endo resto technique.

Many endodontists have cut smaller than traditional shapes but show no lateral recesses filled when treatment is completed. These mediocre irrigation outcomes are the genesis of multi-visit RCT–definitely a step backward in efficiency and elegance of procedural RCT delivery. Note how his MIE instrumentation preserves the native anatomy of root canal systems, making us all better students of endodontic anatomy.

Both Dr. Maupin and I have been early adopters of dynamic guidance for calcified access–to this day one of the coolest technologies I've ever used during RCT. You will see how a 3D camera system with digital tracking software can make your next heinous case feel like you are playing a video game. I have yet to use guidance in a calcified tooth without thinking, 'This is crazy–I cannot believe it works this well".  

Dynamic guidance is the key to well-controlled MIE access procedures in calcified teeth. I would hate to practice without it now.

You will see how vacuum-drawn NaOCl solution can clean 5mm beyond the end of irrigating cannulas when used in a closed system negative pressure environment. You will see how it can be staged in less than 5 minutes, requiring no hands-on time to complete. 

Research has shown a way to irrigate and obturate the most complex root canal systems through the smallest MIE access openings.  

A recent clinical case treated with negative-pressure multi-cann irrigation (note the irrigating cannulas in the middle image). Note the mid-mesial canal and the distal apical delta system cleaned with a closed system and filled three dimensionally despite the minimally-instrumented shapes.  

Dr. Maupin's treatment result in this case shows micro-shapes in the MB1 and MB2 canals and a wild ribbon-shaped palatal canal with multiple apical portals of exit.   

One of the best MIE cases I've seen. It's got everything–from individual (trussed) access openings, to lateral canals filled in spite of the MIE shapes, to a happy face after the fill was completed.

I will also show how root canals systems can be cleaned with any files being used, like this MB2 canal.  

So, if you are tired of seeing this case result....

...and if you like the new "Look" of twenty-first century endodontics...

Join us at Denver International Airport's Westin Hotel on November 13, 2021 for an intense journey into minimally-invasive RCT without losing your mind and wallet. Our greatest objective for this course is to insprie enthusiasm about saving tooth structure while predictably treating entire root canal systems.
