Title: «Esthetic for a Lifetime-Discover the keys»

Abstract: In dentistry, the goals of treatment are often designed for what are patients wish for, even demand. We all see it-instant satisfaction, immediate outcomes. But when we are anticipating treatment for an adolescent, whether it be strictly orthodontics or including interdisciplinary care, we must often take into account the hard and soft tissue changes that occur over the lifetime of that patient. In other words, we commit ourselves to designing treatment with a longer-term view. In this presentation, Dr. Sarver will cover the principles and newly gathered data on how smiles change with time and how we adapt our treatment approaches in both adolescents and adults. We will cover the essential keys to achieve a comprehensive facial and smile appearance and its importance to the immediate and long-term needs of the patient. In this presentation, Dr. Sarver will cover expanded vision and inclusion of multiple dental and medical professional to be partners in planning and implementation of treatment well beyond a mere transaction.

Title: «A face-driven biomechanical way out for the management of Impacted and Transposed Teeth»

Abstract: It is the duty of every orthodontist to provide effective and efficient treatment to all patients in terms of facial esthetics and occlusal function. To realize these goals, simple mechanics can be used to correct the pathway of Impacted and Transposed teeth. Maxillary canines play an important role in creating good facial and smile esthetics, since they are positioned at the corners of the dental arch, forming the canine eminence. Besides, they support the dentition, contributing to disarticulation during lateral movements in certain persons. Canines are the second most frequently displaced and impacted teeth in the dentition, showing a prevalence of 1 to 4%. Around 85% of these misplacements are palatal, and they can occur even in patients with adequate arch length. The simple mechanics to manage these problems will be discussed.

«Out of the box» thinking became the norm to treat certain situations that were not easily correctable previously.

This presentation will highlight the use of simplified but efficient biomechanics to solve these problems.

Title: «Soft Tissue Profile Values in Palestinian Adults»


Objective: To obtain standards for the soft tissue facial profile for male and
female Palestinian adults using Holdaway and Legan-Burstone cephalometric
Materials & Methods: 77 lateral cephalometric radiographs for non-growing
Palestinian adults (46 males and 31 females) with normal occlusion were traced
and measured.
Results: When compared to Holdaway norms, Palestinian adults have similar
values of except for the skeletal profile convexity, H angle, and basic upper lip
thickness, which were larger in Palestinians. When compared with Legan-
Burstone norms (facial form analysis), Palestinians showed similar values except
for decreased mandibular prognathism and increased lower face-throat angle.
Comparison between men and women showed that basic upper lip thickness,
upper lip thickness, and inferior sulcus to H-line were significantly larger in
Palestinian men when compared to Palestinian women.
Conclusion: The results of this study indicates that the soft tissue facial profiles
for Palestinians and the values of Holdaway and Legan-Burstone are different.
Such differences should be taken in to consideration when formulating a
treatment plan for Palestinian patients seeking orthodontic treatment and/or
orthognathic surgery.

How do we move teeth after all? An up-to-date biological insight

Prof. Effie Basdra

In the era of  molecular medicine, artificial inteligence (AI), targeted pharmaceutical approaches and robotic biofabrication of architected biomaterials that heal, the biological underpinning of orthodontic tooth movement, TMJ and fossa remodeling, cranial suture expansion, are gradually being unveiled. To our knowledge mechanical loading and unloading act as the triggering factor that through a series of cellular and molecular events engaging mechanosensitive molecules i.e., polycystins, control bone remodeling. Mechanotransduction seems to be of pivotal importance in all biological systems as it has been demonstrated lately to be also a key regulator in cancer biology and the tumor metastasis process.

Title: «Missing anterior teeth in young patients - face and age oriented ortho-prosthetic treatment»


Abstract: A missing front tooth increases the orthodontic treatment complexity and rises many dilemmas for both orthodontist and prosthodontist. The main treatment principle is to begin with the end in mind, which means starting with a full understanding of the desired result and then working backwards to make it possible. Digital multidisciplinary planning and periodical team evaluation are critical. It is essential that each practitioner is periodically updated on the latest advances in the other profession. The present lecture follows up several young patients who lost their front teeth, discusses the difficulties and presents up-to-date solutions based on face and age-oriented ortho-prosthetic approaches.


Title: «Impacted teeth - essential yet overlooked facts in diagnosis and treatment planning»


Abstract: One of the main factors which complicate treatment of impacted teeth is that the tooth is not visible, therefore positional diagnosis and planning is often difficult. Existing clinical clues are often overlooked even by experts. Recognition of these clues before treatment is essential for early diagnosis, preventive measures and correct planning of the ortho-surgical resolution, while recognition of these clues during treatment is a key in avoiding failures. This presentation provides the clinician tools for a better 3D clinical diagnosis and planning of treatment timing and strategy, by presenting clinical cases and new research data from a multicentre study.

Title «Change the face! Advances in the treatment of growing Class III patients»


Abstract: Recent systematic reviews have shown that maxillary protraction in young patients with a retrognathic maxilla is much more effective when using skeletal anchorage. A minimally invasive approach to establish skeletal anchorage in the upper jaw is to utilize mini-implants inserted in the anterior palate. This insertion site comprises a very good bone quality and quantity. Several clinical studies documented a superior reliability of mini-implants inserted in the anterior palate with success rates ranging between 96% and 98%.

In order to perform simultaneous rapid maxillary expansion and protraction the Hybrid-Hyrax is utilized either in conjunction with a face mask or a Mentoplate. The effectiveness of maxillary protraction can be even enhanced following the Alt-RAMEC protocol.

Utilizing computerized design and metal printing technologies in conjunction with insertion guides the Hybrid-Hyrax can be inserted in just one appointment. The newly developed clinical workflow proved to be very efficient and reliable.

Based on many clinical examples the indications, clinical procedures and outcomes of maxillary protraction in growing Class III patients are discussed.

Title: «Facial esthetics in the eyes of the orthodontist: therapeutic potentials and limitations»

Abstract: Studies indicate that averageness in facial proportions translates into attractiveness. While this tenet was challenged in the definition of beauty going beyond averageness, the average remains a guide for treatment by practitioners concerned with facial esthetics. Accordingly, treatment to the normal Class I occlusion prevails but does not necessarily correspond to favorable or enhanced facial esthetics. Discrepancies among hard structures (bone and teeth) in relation to soft tissue variation in thickness and proportion indicate that treatment short of Class I occlusion may be appropriate as the severity of skeletal discrepancy increases. This concept will be illustrated with treatment reports and research findings.

Title: Facial esthetics: A patient-centered approach.

Lecture summary

Facial and smile aesthetics are the main reasons for patients of all ages to seek orthodontic care. The new paradigm in orthodontic treatment planning focuses on facial and smile appearance, as well as overall improvement in quality of life. However, facial aesthetics and soft tissue morphology are assessed with traditional norms that do not take into consideration patients’ perceptions.

This presentation will focus on factors that influence self-perception of facial and smile appearance. How do objectives features influence our opinion and to what extent do personality and self-esteem affect our perception? Which facial features tend to have the most significant impact on self-perceived facial and smile attractiveness? Within this context, the overall role of the orthodontist in modern times will be revisited and the social impact of our profession will be discussed.

 Learning objectives:

  1. Attendees of this lecture will be able to recognise the effect of physical and psychological factors on self-perception of facial and smile
  2. To evaluate differences between genders in self-perception of facial and smile
  3. To revisit and redefine the impact of orthodontics in patients’ lives and modern

Title: «With the face in mind does orthodontic tooth movement induce the development of gingival recession?»


Abstract: Active orthodontic tooth movement can induce gingival recession when teeth are moved outside the alveolar envelope. However, the available scientific evidence does not give a definitive answer to the question whether orthodontic treatment is a major risk factor for the development of gingival recession in the long-term. The same is true regarding the role of individual patient-related or treatment-related contributing factors.  Four main questions will be addressed: Is orthodontic tooth movement a major risk for gingival recession? Do orthodontically treated patients suffer in the long run more from gingival recession compared to untreated individuals? Does prolonged fixed retention influence the development of gingival recession? How can the periodontist assist in the prevention or treatment of gingival recession? The understanding of the association between orthodontic tooth movement and development of gingival recession is important because of the high number of children, teenagers and adults who are treated orthodontically.

Title: «Improving the quality of smile with the interdisciplinary team approach»

Abstract: Clear Aligners and lingual braces are getting more and more popular nowadays. Especially because of their esthetic appearance and being invisible adult orthodontic treatment has increased its popularity. Many patients, especially adults often have dental needs that may require restorative care, treatment or management of the periodontium and enhancing esthetics in conjunction with braces. In such situations achieving an optimal esthetic and functional result requires the expertise of more than one clinician. In these cases we elect for collaborative approach that involves the patient’s general dentist and other specialists to develop and sequence a unified treatment plan to achieve the best possible result. This interdisciplinary approach to treatment is extremely effective for such complex cases where one specialist alone cannot deal with all aspects of the problem. As a patient you benefit from the combined expertise of many clinicians/ specialists working closely together to develop a blue print to guide your care. This collaborative approach ensures that as a patient you receive the best possible care at every step of the treatment process. The team approach allows for more efficiency with a better, more stable and lasting treatment outcome.

Title: «Face or Occlusion?»

Abstract: Orthodontists around the globe are trained to treat every individual to an ideal Class I occlusion. The use of new biomaterials combined with advanced technology offer a considerable armamentarium to facilitate almost every case in the desired occlusion.

Individuals with skeletal discrepancies, however, constitute cases requiring good judgment, critical evaluation, as well as an individualized treatment plan from both the orthodontist and the oral and maxillofacial surgeon in order to achieve good results.

We will present several cases, which in spite of the fact that they were orthodontically treated in a nice class I occlusion, the face and the skeletal discrepancy were overlooked by the orthodontist.  These four patients were referred to our clinic after the completion of the orthodontic treatment complaining about the esthetic outcome.

This presentation illustrates very clearly:

  1. a) The failure of the orthodontist to understand the real major complaint of the patient or
  2. b) The inability of the orthodontist to present the option of surgical correction to the patient, either because of lack of experience or due to inadequate knowledge or personal beliefs regarding surgical orthodontic approaches.

A second treatment was necessary in all four cases.  The extra cost and the extra time involved are issues which illustrate the lack of good judgment initially. The new treatment approach that focuses equally on the occlusion and the face will be presented. This presentation emphasizes emphasis on the cooperation between the orthodontist and the oral and maxillofacial surgeon.

Title: «Clinical interdisciplinary management of a patient with cerebral palsy, Class III malocclusion, anterior open bite and gingival overgrowth»

Abstract Cerebral palsy (CP) is a developmental disorder that leads to impaired muscle function. Patients with CP often suffer from poor orofacial muscle control which may negatively influence occlusal development and craniofacial growth, and lead to dentofacial disharmony and functional limitations. However, medical and behavioral challenges in patients with CP often prevent practitioners from offering the necessary dental care. The clinical interdisciplinary management of a 20-year-old male patient with CP, anterior open bite, Class III malocclusion, and gingival overgrowth will be presented including a combined orthodontic, periodontal and orthognathic surgery treatment approach.

PREDICTABILITY, a key word for successful treatment plan in aligner orthodontics

In every step of your treatment plan assembly you should ask yourself “Is this movement, or sequence of movements, predictable”?

Why? Because your input in your treatment plan simulation will always be achievable virtually but will you get it in real life?

That’s the question which will make a difference between successful outcome or and a failure.

In this presentation I will guide you through treatment plan assembly emphasizing predictability in every step of the way which will give you a successful outcome in aligner orthodontic treatment.

When it comes to cases like open bites, wether they are dental, skeletal or both at the same time, I am sure that we all will categorize them as challenging and difficult.

After treating countless open bite cases with fixed appliances (brackets and wires) and also with Invisalign aligners I can easily state that my “weapon of choice” for open bite malocclusion is absolutely Invisalign aligners.

The predictability, efficiency, practicality and capability of Invisalign aligners in treating open bites is second to none!

Join me in my lecture where I will show you cases, mechanics, attachment, and protocols for treating various open bite and other challenging malocclusions with Invisalign aligners.

Title: "Effective oral hygiene for the orthodontic patient"

Abstract: Orthodontic therapy, due to the insertion of either fixed or removable appliances, causes significant changes in the oral microbiome. Without proper guidance and continual motivation it is relatively easy for patients to inadequately clean around the orthodontic appliances and thus fail to sufficiently control the bacterial load around teeth and in the oral cavity. As a result, demineralization of the tooth surfaces and caries development and/or gingival inflammation may ensue. Oral hygiene instruction and monitoring of its proper implementation is of paramount importance for the orthodontic patient and should be initiated even before the start of treatment. Indeed, the patients undergoing orthodontic therapy should invest extra time and effort in performing oral hygiene, since they in essence comprise a distinct group of high-risk patients for dental disease. Therefore, time must be spent in the initial consultations to fully explain the various aspects of oral health and disease and the methods of oral hygiene that must be used. Throughout the various stages of therapy the level of oral hygiene must be evaluated and proper supplemental information given to the patient. Current research is focused on reducing the impact of modifying factors (i.e. cementing material or bracket type) on the adhesion and/or retention of bacteria or the use of clear aligners to facilitate the daily cleaning of teeth. who are treated orthodontically.

Title: "Safety and effective disinfection in the Orthodontic clinic"

Abstract: he specialty of orthodontics has the advantage, among other things, of not using materials, tools and techniques that create a serious substrate for cross-infections that are common in interventional and reconstructive dentistry. However, oral flora remains present and modern implantation techniques have significantly altered infection control protocols.

Rotary tools are the most vulnerable to corrosion processes and therefore it is advisable to avoid wet heat techniques for sterilisation. The use of modern safe, effective and non-aggressive cleaners, lubricants and disinfectants is the solution of choice for the proper functioning of the orthodontic practice, provided that they are used correctly and precisely for the intended and prescribed uses.

Alcoholic compounds, together with quaternary ammonium compounds, together with Enzymes are the materials of choice for the disinfection and cleaning of orthodontic tools, provided that their application times and indications of use are followed.

AI applications in Orthodontics are relatively young but growing at a rapid pace.

This presentation aims to: 1) Explain conceptually how AI algorithms work 2) Classify AI applications and their scope in orthodontics 3) Assess clinical scope, performance and risks associated with therapeutics 4) Propose an outline for audit of AI applications in orthodontics.

The lecture will explain how AI is a set of tools for problem-solving that can assist orthodontists with extra powerful and applied tools to provide better standards of care. AI can assist orthodontists to choose the best way to move a tooth or group of teeth, but AI today completely ignores the existence of oral diseases, does not fully integrate facial analysis in its algorithms, and is unable to consider the impact of functional problems in treatments.

The lecture will also dwell upon the risks associated with AI application.As AI enters practice, clinicians need to know how law will assign liability for errors that arise from interaction between algorithms and practitioners. These issues are likely to arise sooner rather than later. Responsibility and the varied scope of these applications will also be deliberated.

PREDICTABILITY, a key word for successful treatment plan in aligner orthodontics

In every step of your treatment plan assembly you should ask yourself “Is this movement, or sequence of movements, predictable”?

Why? Because your input in your treatment plan simulation will always be achievable virtually but will you get it in real life?

That’s the question which will make a difference between successful outcome or and a failure.

In this presentation I will guide you through treatment plan assembly emphasizing predictability in every step of the way which will give you a successful outcome in aligner orthodontic treatment.

When it comes to cases like open bites, wether they are dental, skeletal or both at the same time, I am sure that we all will categorize them as challenging and difficult.

After treating countless open bite cases with fixed appliances (brackets and wires) and also with Invisalign aligners I can easily state that my “weapon of choice” for open bite malocclusion is absolutely Invisalign aligners.

The predictability, efficiency, practicality and capability of Invisalign aligners in treating open bites is second to none!

Join me in my lecture where I will show you cases, mechanics, attachment, and protocols for treating various open bite and other challenging malocclusions with Invisalign aligners.
