| 2 |  +5Even a familiar technique doesn’t always deliver the same predictable result 🤯
Often, the key decisions are made before surgery: interproximal support, CEJ position, tissue thickness, local anatomy, and whether the flap can be advanced without tension.
📌 In the carousel, we’ve put together 5 mistakes that can reduce the predictability of root coverage, based on Giovanni Zucchelli’s work.
Think of it as a short practical checklist for treatment planning.
Swipe through the slides for the key steps, diagrams, and points worth checking before surgery.
📍 By the way, Giovanni Zucchelli is coming to Moscow on April 5–7, 2027.

| 5 |  +5Limited mouth opening is a clinical sign, not a diagnosis. The same complaint can result from very different mechanisms — from a protective muscular response to an intracapsular restriction.
🔍 That is why it is important to assess not only how many millimeters the patient can open their mouth, but also how the restriction developed, what happens during slow opening, whether muscle pain is present, and how the mandible moves.
For example, with protective co-contraction, the range of motion may increase during slow opening. In contrast, disc displacement without reduction (closed lock) creates a mechanical restriction that prevents normal condylar translation.
📚 In the carousel, we present a step-by-step differential diagnostic algorithm based on Jeffrey P. Okeson’s Management of Temporomandibular Disorders and Occlusion.

| 7 |  Recession. Insufficient tissue volume. An unnatural contour. Compromised esthetics.
Even a perfectly positioned implant cannot guarantee an ideal outcome if the soft tissues do not provide the right conditions.
How can you increase soft-tissue volume? Which technique should you choose for a specific clinical situation? How do you manage the graft and shape the tissue contour so that the result looks natural not only immediately after treatment, but over time?
📍 On November 16–17, 2026, in Budapest, Ricardo Kern will lead the hands-on course
“Soft Tissue Management Around Implants.”
Over two days, participants will explore the entire pathway to a stable, esthetic outcome — from immediate implant placement and loading to the development of a biologically driven emergence profile and prosthetic management in the esthetic zone.
And a major focus of the course will be hands-on training.
Under Ricardo Kern’s guidance, you will practice:
🔵 VIP-CTG — Vascularized Interpositional Periosteal-Connective Tissue Graft technique
🔵 SMILE technique
🔵 Table-Top technique for connective tissue graft harvesting
🔵 CAF and T-CAF — Coronally Advanced Flap and the tunneling approach

| 8 |  +5In the esthetic zone, implant placement is not always the first step.
In this clinical case by Ricardo Kern, a significant horizontal and vertical tissue deficiency required a very different treatment sequence: first, hard- and soft-tissue reconstruction, followed by 8 months of healing, and only then implant placement using a surgical guide.
❓Why was it important to perform the reconstruction in stages?
❓How can the reconstructed soft-tissue volume be preserved during implant placement?
❓And what role did the provisional restoration play in the final outcome?
📌 In the slides, we break down Ricardo Kern’s case step by step — from the initial tissue deficiency to immediate provisionalization.
On November 16–17 in Budapest, Ricardo Kern will lead an event dedicated to soft-tissue management around implants, with a focus on the clinical decisions that determine the stability and esthetics of peri-implant tissues.

| 9 |  🇮🇹 Arnaldo Castellucci invites you to Florence!
On September 18–19, Arnaldo Castellucci will be speaking at the European Endodontic Congress, with a lecture focusing on two technologies that directly impact the precision of endodontic treatment: next-generation apex locators and ultrasonic preparation of the endodontic access cavity.
During his lecture, Castellucci will cover:
💥 why accurate working length determination remains a critical step in endodontic treatment and the limitations of traditional methods
💥 how third-generation apex locators work and how to interpret their readings correctly
💥 why combining different methods can improve the accuracy of working length determination
💥 the role of the operating microscope and ultrasonics in modern endodontic access preparation
💥 the advantages of ultrasonic tips over traditional burs and their clinical indications
🎥 In this video, Arnaldo Castellucci personally invites colleagues to join him at the congress in Florence.

| 10 |  +5In endodontic retreatment, prognosis largely depends on how accurately the clinician identifies the cause of the initial treatment failure and assesses the amount of remaining tooth structure.
⚠️ Aggressive canal enlargement, attempting to reach the radiographic apex at all costs, or removing an obstruction can lead to further dentin loss, perforation, and reduced root strength.
At the same time, certain radiographic findings, such as minor sealer extrusion beyond the apex, do not necessarily explain persistent periapical inflammation — the source of persistent infection must be identified.
📚 In today’s slides, we review several clinical situations from Arnaldo Castellucci’s Endodontics, Volume 2: when retreatment is truly indicated, which findings should prompt a change in treatment strategy, and when a more conservative approach may help improve the tooth’s prognosis.
🇪🇺 The European Congress of Endodontics will take place on September 18–19, with Arnaldo Castellucci joining other leading experts in modern endodontics.
If you’d like to hear Castellucci in person and spend two days immersed in endodontics, join us at the Congress! Leave a + in the comments to receive more information. | 137 |
| 11 |  Learning Neuro-Occlusal Rehabilitation from Planas is a rare opportunity for any clinician 🦷
In clinical practice, we often see this situation: treatment has been completed, contacts have been checked, restorations are well adapted. Yet the patient continues to chew on one side, reports overload, or complains of discomfort in the TMJ area.
In such cases, the clinician needs to understand:
where function breaks down and how it relates to occlusion, mastication, and mandibular movement.
🗺On November 27 in Warsaw, we will host the seminar
“Neuro-Occlusal Rehabilitation. Seminar by Carlos de Salvador Planas”
Program:
⏺ Introduction to Neuro-Occlusal Rehabilitation (NOR)
⏺ Physiology of mastication: Planas’ Laws
⏺ The concept of balanced occlusion in Neuro-Occlusal Rehabilitation (NOR)
⏺ Planas Appliances
⏺ Treatment planning in Neuro-Occlusal Rehabilitation

| 12 |  +5When the occlusion looks stable, but function breaks down 🦷
Clinicians often see this kind of case: the contacts have been adjusted, the restorations are well adapted, yet the patient keeps coming back with overload, TMJ discomfort, or a pronounced habitual chewing side.
In these situations, it is important to assess mandibular movement:
📐 how freely laterotrusion occurs
🔍 where the restriction appears
🧩 why one side becomes more active than the other
⚖️ how this relates to the occlusal plane and the masticatory pattern
In our new post, we discuss the Planas algorithm — how the functional angle helps identify asymmetry in the masticatory trajectory and better understand where to look for the cause of the imbalance.

Would you like to receive the full program, pricing, and participation details?

| 14 |  +6In 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.
Save this post as a quick clinical reference.

| 16 |  +5Today, 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.”

| 18 |  The aligner is programmed to move the tooth. But will the tooth actually follow the plan? 🦷
A digital setup may look flawless, yet clinical reality can bring anchorage loss, insufficient intrusion, uncontrolled extrusion, or spaces that refuse to close as expected.
The problem often lies not in the aligner system itself, but in the biomechanics built into the treatment plan.
📍 On September 3–5 in Warsaw, Giorgio Fiorelli will present the course “Aligner Biomechanics” for orthodontists who want to understand the mechanics behind every tooth movement and achieve more predictable clinical outcomes.
The theoretical part will cover:
🔹 fundamentals of aligner biomechanics
🔹 limitations of tooth movement and anchorage control with aligners
🔹 extraction and non-extraction treatment
🔹 deep bite correction and expansion
🔹 the use of skeletal anchorage
🔹 hybrid approaches for molar uprighting, true intrusion, space closure, and deep bite correction
During the hands-on typodont sessions, you will practise:
⚙️ molar uprighting mechanics
⚙️ intrusion mechanics using different auxiliary devices
⚙️ controlled extrusion with various appliances
⚙️ space-closing mechanics
⚙️ hybrid treatment planning and selecting the most appropriate appliance for each clinical situation
Leave a “+” in the comments, and we will send you more information about the course in Warsaw ➕ | 139 |
| 19 |  +5How will a tooth move after activation — and can you predict it in advance?
In orthodontic treatment, the outcome depends not only on the selected archwire, aligners, elastics, or miniscrews.
What truly matters is the force system created by the appliance:
▪️ force direction and magnitude
▪️ the position of the center of resistance
▪️ moment
▪️ anchorage
▪️ the biological response of tissues
In Dr. Giorgio Fiorelli’s approach, biomechanics does not begin with choosing the tool. It begins with the question:
What movement do we want to achieve — and what side effects should we expect?
In this carousel, we break down a practical algorithm:
⏺ how to define the final goal
⏺ how to design the force system
⏺ how to assess whether the chosen mechanics is clinically feasible
⏺ how to predict tooth movement before activation
This is the skill that distinguishes a clinician who controls treatment from one who only reacts to changes after they occur.
📍 On September 3–5 in Warsaw, at Dr. Giorgio Fiorelli’s practical course “Biomechanics with Aligners,” we will take these principles further and discuss their application in aligner therapy: how to control tooth movement, predict side effects, and make biomechanical decisions consciously.
