| 2 |  +5š¦· The loss of five anterior teeth combined with severe alveolar bone deficiency presents a clinical situation in which the outcome depends on close coordination between every stage of treatment.
This case reviews the multidisciplinary rehabilitation of a patient following severe trauma, including diagnosis, treatment planning, orthodontic preparation, bone grafting, implant placement, and the 2-year outcome.
The authors place particular emphasis on implant positioning, occlusal conditions, support of the subnasal region, and long-term esthetic risks in the anterior maxilla.

| 3 |  šŖ” The esthetic zone leaves no room for compromise.
Root coverage procedures, management of a thin phenotype, and soft tissue reconstruction around implants all require meticulous attention to detail. Every millimeter matters ā from flap design and graft fixation to the long-term stability of the gingival margin.
We invite you to join Giovanni Zucchelliās course, where his signature approaches to mucogingival surgery will be explored, including the treatment of single and multiple recessions, the use of CTG, EmdogainĀ® and collagen matrices, as well as soft tissue reconstruction around implants.
A special focus will be placed on hands-on training, surgical video demonstrations, and the discussion of clinical cases.

| 4 |  +6What Determines the Stability of the Gingival Margin After Root Coverage?
When treating gingival recessions in the esthetic zone, it is important to evaluate not only the depth of the defect and the ability to advance the flap coronally.
For long-term stability, the following factors are essential:
š¹ soft tissue thickness;
š¹ width of keratinized tissue;
š¹ flap stability;
š¹ quality of graft fixation;
š¹ tension-free flap closure.
A connective tissue graft should not be used by default. It is indicated when there is a need to improve the biological conditions for healing: to increase tissue thickness, support the gingival margin, and reduce the risk of recurrent apical displacement.
In this post, we discuss when CTG is particularly justified and which factors should be considered before selecting a surgical approach.
š On April 5ā7, 2027, Giovanni Zucchelli will lead a hands-on course in Istanbul:

| 6 |  +5š¦· A fractured instrument in the root canal is not always an indication for immediate removal.
What matters far more is determining which approach will truly improve the toothās prognosis: removing the fragment, bypassing it, or avoiding aggressive intervention altogether.
Today, endodontics relies increasingly not on technical skills alone, but on a precise analysis of the clinical situation. CBCT findings, root canal anatomy, the amount of dentin that would need to be removed, the location of the fragment, and the degree of infection beyond it are the factors that ultimately determine both the treatment strategy and the long-term outcome.
š¬ In his research, Yoshi Terauchi proposes viewing fragment retrieval not as an isolated procedure, but as a decision-making algorithm in which the following factors play a key role:
āļø visibility under the microscope
āļø the degree of canal curvature
āļø the length of the fractured instrument
āļø the biological prognosis of the tooth
In this carousel, we discuss when an attempt to remove the fragment is truly justified, when bypass is the preferred option, and why, in some cases, leaving the fragment in place may be the most rational decision.
š If you would like to approach complex retreatment cases with greater confidence, we invite you to join āAdvanced Non-Surgical Retreatment and Fragment Retrievalā, an educational event led by Yoshi Terauchi.

| 7 |  What might dentists miss when they focus only on teeth?
TMJ disorders, headaches, muscle tension, cervical discomfort, and unstable treatment outcomes are often linked to factors that extend far beyond the dental arches.
Today, understanding the interplay between occlusion, posture, and the musculoskeletal system is becoming an essential part of clinical decision-making.
We invite you to join Mariano Rocabadoās seminar in Budapest, where he will present concepts that have helped dentists and physiotherapists around the world rethink the connection between occlusion, head and neck posture, and TMJ function.
During the seminar, we will discuss:
āŖļø how to evaluate the cranio-cervico-mandibular relationship before starting rehabilitation;
āŖļø how occlusion, bruxism, posture, and the cervical spine influence functional stability;
āŖļø how to work with articulators, facebows, and occlusal splints in real clinical cases;
āŖļø practical techniques for TMJ and cervical stabilization, including decompression and neuromuscular integration;
āŖļø how to build effective collaboration between prosthodontists, orthodontists, maxillofacial surgeons, physiotherapists, and dental technicians.

| 8 |  The most costly mistake with veneers begins before preparation
How much enamel should be preserved? Where should space be created for ceramic? How can a smile design be transferred into clinical practice so that the result is not only beautiful, but also predictable?
These are the questions at the heart of Stefen Koubiās Christmas seminar in Prague ā dedicated to ceramic veneers as a precise system of clinical decisions.
During the seminar, we will discuss:
š¦· how to create a smile design project and transfer it into clinical practice through a mock-up;
š¦· how to manage patients with pathological tooth wear;
š¦· which materials to choose in prosthodontics and dental laboratory practice in 2026ā2027;
š¦· how to build a step-by-step protocol for adhesive bonding of veneers without critical mistakes.

| 9 |  +6š¦· Veneers do not begin with ceramic.
Nor with shade selection, tooth shape, or the final smile photograph.
In a clinically mature approach, veneers begin with a different question:
how much tooth structure can we preserve to achieve an esthetic and long-term predictable result?
Enamel is one of the key prognostic factors. Veneer planning requires not only an artistic eye, but also a precise understanding of biomechanics, preparation design, mock-up, and bonding protocols.
In Stefen Koubiās book āCeramic Veneers: 20 Recipes for Smile Design,ā esthetics is presented as a system of clinical decisions: from smile analysis to transferring the design project into the patientās mouth.
This is exactly what Stefen Koubiās Christmas seminar in Prague will focus on:
āCeramic Veneers: Smile Architecture and Predictable Esthetics.ā

| 10 |  š¦· Sometimes the hardest part of treatment is not choosing the protocol ā itās understanding where to begin
A patient may present with several issues at once: tooth wear, overload, esthetic concerns, periodontal risks, changes in occlusion, old restorations.
And in these cases, the clinician needs more than just a treatment plan.
The real questions are:
What is the key problem here?
Which risk must not be missed?
What could affect the result in one, three, or five years?
The first module with Dr. Tak-On Ryan Tse is dedicated to the fundamentals of the Kois concept ā a system that helps clinicians break down complex cases into clear diagnostic steps.
During the seminar, doctors will discuss:
š¹ Kois 10 ā what clinical data should be collected before treatment planning
š¹ assessment of periodontal, biomechanical, functional, and dento-facial risks
š¹ the Kois 10-step diagnostic system
š¹ how to identify the āweakest linkā in a clinical case
š¹ dento-facial analysis: tooth display, lip position, gingival contour, and tooth position in relation to the face
š¹ functional diagnostics and the role of the Kois deprogrammer

| 12 |  +6Does smoking always mean a poor prognosis for treatment with the All-on-4Ā® concept?
Smoking is widely recognized as a risk factor in implant dentistry. But does it primarily affect implant survival, or does it have a greater impact on long-term bone stability?
In a 5-year retrospective study, Dr. Paulo Malo and colleagues compared the outcomes of 100 smokers and 100 non-smokers who underwent full-arch mandibular rehabilitation using the All-on-4Ā® concept.
The findings were more interesting than expected.
š¦· Implant survival rates remained high in both groups:
š¹ 99.0% in non-smokers
šø 96.9% in smokers
However, the results were different when marginal bone loss was evaluated:
š¹ 1.68 mm in non-smokers
šø 1.98 mm in smokers
These findings suggest that, for smokers, the primary concern is not early implant failure, but long-term marginal bone loss.
š Weāve summarized the study in this carousel. Swipe through and let us know your thoughts in the comments. Do you think smoking should influence treatment planning for full-arch rehabilitation?

| 14 |  +6In endodontics, overly aggressive instrumentation rarely looks like a mistake in the moment.
On the contrary, it may feel like the clinician is making the treatment more reliable: enlarging the canal more thoroughly, improving irrigant access, and creating a more predictable shape for obturation.
But the clinical line between adequate shaping and overtreatment can be very thin.
ā ļø Excessive apical enlargement, increased taper, loss of working length, or canal transportation may lead not to better disinfection, but to loss of apical control, extrusion of infected contents beyond the apex, and a compromised prognosis.
This is why modern instrumentation is not just about choosing a file or a system. It is about assessing anatomy, understanding instrument mechanics, and anticipating risk zones before they become complications.
In this carousel, we review 5 mistakes to eliminate from your protocol if you want to make canal shaping safer and more predictable.
