Instrumentation in Endodontics Today — Michael Solomonov’s Hands-On Course in Warsaw 🇵🇱 October 17–18 — two days focused on how to choose instruments not out of habit, but according to the anatomy and complexity of each individual root canal. During the course, Michael Solomonov will cover in detail: 🔵 the role of stainless-steel, NiTi, and modern “scraping” instruments 🔵 controlled memory wire and its role in primary instrumentation 🔵 continuous rotation vs reciprocation: indications, limitations, and common selection errors 🔵 the risks of over-enlarging the canal orifice, the apical preparation, and creating excessive taper 🔵 SAF, XP-Endo Shaper, XP-Endo Finisher, and other systems 🔵 an algorithm for selecting and combining instrumentation systems according to root canal system complexity The program includes a detailed review of a wide range of systems, including HyFlex, TruNatomy, Race EVO, ProTaper Gold, ProTaper Ultimate, Mtwo, VDW.Rotate, OneCurve, WaveOne Gold, Reciproc Blue, TF Adaptive, SAF, XP-Endo, and others. And on day two — hands-on training under an operating microscope 🔬 🔵 locating root canals 🔵 identifying calcified canals and MB2 🔵 scouting 🔵 instrumentation with continuous-rotation, reduced-taper systems 🔵 working with controlled memory wire 🔵 use of SAF 🔵 radiographic assessment of the treatment result 📍 Warsaw 📆 October 17–18, 2026 🎓 “Instrumentation in Endodontics Today” — Michael Solomonov’s hands-on course Would you like to receive the full program, pricing, and participation details?

In endodontics, a patient’s age can provide valuable clues about the root canal anatomy you may expect even before instrumentation begins. As patients age, the continued deposition of secondary and tertiary dentin leads to a reduction in pulp chamber volume, changes in access to canal orifices, and progressively narrower, more frequently sclerotic canals. At the same time, the clinical priorities also change: ☑️ in younger patients — preserve tooth structure and avoid unnecessary dentin removal ☑️ in middle-aged patients — account for isthmuses, oval canal areas, and complex internal anatomy ☑️ in patients over 40 — safely negotiate and shape narrow, sclerotic canals Importantly, there is no universal instrumentation protocol. Instrument selection, the extent of apical enlargement, additional canal-wall preparation, and the irrigation strategy should all be based on the actual anatomy of the individual tooth, with age serving only as one clinical guide. 📚 In the carousel, we review practical recommendations from the work of Michael Solomonov and co-authors for patients aged ≤20, 20–40, and ≥40 years.

Today, we’re reviewing a clinical case by Pierpaolo Cortellini — treatment of tooth 11 with a deep intrabony defect in a patient with severe generalized periodontitis 🩸 The patient presented with severe inflammation, pathological tooth migration, hypermobility, and deep periodontal pockets. The first stage focused on cause-related periodontal therapy and inflammation control. The decision to proceed with regenerative treatment was made only after re-evaluation. During surgery, a deep, wide, 10 mm one-wall intrabony defect was identified. Cortellini used a combined regenerative approach with preservation of the soft tissues and achievement of primary wound closure. ☑️ Outcome: at 1 year, there was a 7 mm gain in clinical attachment and complete resolution of tooth mobility. At 6 years, the tooth had completely and spontaneously realigned, and the result remained stable. In the carousel, we break down the key treatment stages and clinical decisions that made it possible to preserve the tooth. 📍 On October 15–16 in Florence, Pierpaolo Cortellini will lead the advanced seminar “Regenerative Periodontal Surgery: Treatment of Intrabony Defects.” Want to learn more about the seminar?

Predictable aligner treatment begins not with the digital setup, but with an understanding of biomechanics 🦷 Even carefully planned digital tooth movements are not always fully expressed clinically. This may be due to insufficient anchorage control, the way forces are transmitted through aligners, the limitations of certain tooth movements, or an inappropriate choice of auxiliary mechanics. 📍 On September 3–5 in Warsaw, Giorgio Fiorelli will present the course “Aligner Biomechanics.” The theoretical part will cover: ⏺ fundamental principles of aligner biomechanics ⏺ limitations of tooth movement and the principles of anchorage control ⏺ treatment planning with and without extractions ⏺ biomechanics of deep-bite correction and arch expansion ⏺ the use of skeletal anchorage ⏺ hybrid approaches to molar uprighting, true intrusion, space closure, and the correction of vertical discrepancies During the hands-on typodont session, you will practise: ⚙️ molar uprighting mechanics ⚙️ different intrusion protocols ⚙️ controlled extrusion using various auxiliary appliances ⚙️ space-closure mechanics ⚙️ planning hybrid treatment and selecting the appropriate appliance for each clinical indication Leave a “+” in the comments, and we’ll send you more information about the course in Warsaw ➕
