B2 INDUSTRY Endo Tribune U.S. Edition | April 2022 The story behind the Munce Discovery Burs By C. John Munce, DDS, FICD W ell into the early 2000s, no endodontically inspired long/stiff/narrow-shafted troughing bur existed. To meet my own clinical needs, in 2003, I began modifying the shafts of existing latch-type slowspeed round carbide burs by necking them down at the chairside as needed for a specific clinical case (Figs. 1 and 2). In a lecture at the pre-session meeting of the 2005 American Association of En- dodontists (AAE) Annual Session in Dal- las, I demonstrated in clinical videos on the huge screen how I made these unique long/stiff/narrow-shafted round trough- ing burs at the chairside using both high- speed and slowspeed handpieces operat- ing simultaneously to “hand-mill” the shafts to a 1 mm diameter, and I suggest- ed that colleagues should do the same. To ensure that interested colleagues would be able to see and test these fledg- ling troughing burs, and then make the burs themselves as I had demonstrated, I had 1,000 of them manufactured and handed to attendees as they exited the hall. To that point, it had never been my in- tent to venture into the bur design and manufacturing arena, but during the next year, at meetings and other encoun- ters, I was told by colleagues who had been at the Dallas AAE that they still had that sample bur, and sometimes they would pull it from a pocket to prove it. They begged me to manufacture these burs for them, as they confessed they were never going to make them at the chairside as I had demonstrated. I already had a small clinical products company, CJM Engineering Inc., and so in early 2006, after trying to literally “give” the troughing bur idea to several bur manufacturing companies without suc- cess — in one instance, the new products committee of a large dental bur compa- ny concluded there was simply no mar- ket for such a bur — I decided to begin manufacturing and distributing these burs myself through CJM Engineering, still the manufacturer and exclusive worldwide distributor of Munce Discov- ery Burs today. See our introductory ad for these burs from 2006 (Fig. 3). Below is a rough timeline of the in- troduction of significant features of the Munce Discovery Bur line since its inception. Each of these modifications Figs. 1, 2 (above): The lack of a long/stiff/ narrow-shafted troughing bur led to chairside fabrication to meet the need. Fig. 3 (at left): The first ad (2006) announcing the release of Munce Discovery Burs in four head sizes (#1/2, #1, #2 and #4) and one length (34 mm). Root Canal Projectors are no longer available. Figs. 4a, b (below): The view corridor opened up by the long shaft offers visual and physical access to deep target areas, while the narrow shaft greatly reduces shaft impingement on access cavity walls. Photos/Provided by Dr. C. John Munce was born of my own experience in ap- plying these burs in diverse clinical cir- cumstances combined with the freely offered suggestions and requests for modifications from colleagues around the globe. • The Munce Discovery Bur line started with 34 mm-long burs only and in four head sizes: #1/2, #1, #2 and #4 (Fig. 3). • At that time, we produced the 1 mm- diameter shaft on all four head sizes. 2007 2006 • A knowledgeable friend in the dental instrument manufacturing business, Lonnie Graybill of Integra-Miltex, sug- gested the name, Munce Discovery Burs, and it stuck. • We added the 31 mm-long burs to the line. • To distinguish the two different lengths, we began referring to them as Munce Discovery Bur Deep and Shallow Troughers. Fig. 5: Stiffness of Munce Bur shaft v. noodling of Mueller Bur shaft. • We added our tiniest head size, #1/4 — with a head diameter equal to the tip of a #50 K-file — and a #3 head size, to both Deeps and Shallows. • We added 3 mm “sounding” rings to the shafts of the Deeps (Figs. 5 and 6). • We introduced the 31 mm-long #6 Endodontic Cariesectomy Bur. • Although “troughing” as an endo- specific operation associated with ul- trasonic tips was already developing its own vocabulary within the endodontic community, the specific vernacular for troughing when using burs was different and was yet to be developed. Terms we introduced or refined to ap- ply to troughing when using Munce Dis- covery Burs included: — View corridor — the view beyond the handpiece head to the target area, which is much improved with 31 mm-long and 34 mm-long narrow-shafted burs be- cause the extra length draws the hand- piece head away from the target area, and the decreased diameter of the shaft puts much less visual “noise” into the view corridor (Figs. 4a, b). — Shaft impingement — occurs on ac- cess cavity walls with 2.35 mm-diameter shafts of standard slow-speed burs.

Other long-shafted burs have shafts that are too narrow, sacrificing control and leading to “noodling” of the shaft under troughing and other opera- tions (Fig. 5). — Noodling — not a feature of the Munce Discovery Burs. This undesirable feature was specifically designed out of the Munce Discovery Bur shafts (Fig. 5). — Heatless and virtually non-breakable — important features that distinguish these burs from ultrasonic tips. 2010 • For ease of head-size identifica- tion, we added color bands to the shafts (Fig. 6). 2011 • We reduced the shaft-diameter to 0.7 mm on the last 10 mm of the three smallest head sizes in both Deeps and Shallows (Fig. 6) to facilitate deeper ex- ploration and shaft-parallel cement-line dissection (Fig. 7). Although 0.7 mm is very narrow, the specific geometry maintains the trade- mark stiffness of the shaft and facilitates cement-line dissection around posts and silver points while the shaft of the bur is virtually parallel to the long axis of the post or silver point. Shaft-parallel cement-line dissection is completely impossible with 2.35 mm- diameter shafts of standard slowspeed burs. 2015 • A cotton plier insertion ledge (Fig. 6) was added at the transition from the 2.35 mm-diameter portion of the shaft to the 1 mm-diameter portion to facilitate ease of insertion of the bur into the spinning handpiece while protecting the color band from abrading under slippage of the cotton plier, which could otherwise occur. • We modified the head geometry (Fig. 6) to prevent catching on the out- About Dr. Munce C.

Teeth.” 2017 to the present • We continue to resist the suggestion by some to downgrade this unique spe- cialized bur from a carbide-tipped bur to a stainless-steel bur in order to reduce costs on the expectation of perhaps in- creasing sales volume. Our view is that this would be a shortsighted strategy that would lead to an inefficient instru- ment, subsequently substandard clinical results and dissatisfied clinicians and pa- tients. From necessity, to idea, to sketch-on-a- napkin, then invention, technical draw- ing, prototyping, bench-testing, collegial input, tweaking, manufacturing, mar- keting and worldwide distribution — to mention just some of the many steps involved — CJM Engineering has always listened to the needs of clinicians in our specialized discipline and endeavored to be the absolute best that we can be in the multi-faceted process of not just being a pass-through for somebody else’s prod- ucts but rather a company that delivers previously nonexistent high-quality key products invented by an endodontist for endodontists and endo-savvy dentists worldwide. Although it may seem to be a simple product at first glance, in reality, a truly complex instrument such as this doesn’t just roll off the production line of a bur company. It requires ongoing, open- to-improvement, experiential clinical knowledge to develop a high-quality in- strument that will stand the test of time in the hands of some of the world’s most talented — and critical —clinicians: en- dodontists and endo-savvy dentists. CJM Engineering is not a bur company; we’re a “help clinicians save people’s nat- ural dentition” company. Full stop.
