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: «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: «Progressive self-ligating concepts: esthetic considerations and clinical

strategy in challenging cases»


Abstract: The science of orthodontic diagnosis are the norms and numbers that define the lines between which the game of orthodontics is played. On occasion, the art of orthodontics presents itself via cases that challenge the practitioner to question these norms in search of the ideal balance of form and function. This lecture will present a number of these types of cases. With each case the speaker will walk through his diagnosis including micro-esthetic preferences. Treatment sequencing and step by step clinical strategy will be discussed.


Title: «Protocol to maximize efficiency in a self-ligating appliance»


Abstract: One of the proposed advantages of self-ligating (SL) brackets is overall treatment efficiency. Over the course of a patient's orthodontic treatment, there are hundreds of small decisions made by the practitioner that greatly influence this efficiency. This lecture will review the speaker's preferred sequencing of mechanics to optimize treatment within a SL system. Whether you are a long time user of SL brackets or just looking to get started, this lecture aims to provide practical advice on getting the highest performance out of your high performance bracket.

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: «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.

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 sterilization. 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.

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: «Is the Future of Orthodontics Clear?»

Abstract: Dr. Moshiri will discuss how to incorporate adjunct mechanics like lingual bite ramps, elastic buttons, and Phase I Expanders to ensure your Invisalign cases finish predictably. If you're looking to pick up several pearls on diagnosing and executing your Invisalign cases effectively, then you won't want to miss this presentation. Invisalign is an incredibly effective appliance system when the treating doctor utilizes proper evaluation of appropriate records, combined with sound judgment during the diagnostic phase of treatment. Participants will garner how to properly design the ClinCheck treatment plan, including a better understanding of such movements as torque, expansion, and anterior intrusion in order to avoid possible iatrogenic sequelae (i.e posterior open bites). Join Dr. Mazyar Moshiri as he also reviews the treatment nuances of class II malocclusions with the Invisalign appliance.

The following 5 pearls will be elaborated upon:

  1. Up to 80% of class II malocclusions have poor molar rotation. The correction of this greatly aids in molar classification and opening of space for subsequent class I correction of the remaining buccal dentition. Invisalign is very proficient at achieving this correction.
  2. The information and control offered through proper a diagnosis (i.e. any known tooth size discrepancy) combined with the use of Clincheck is instrumental in determining the mechanics used for class II correction.
  3. Segmental distalization with use of the aligner is very effective for class II correction. Proper attachment set-up and sequencing are an important aspect of the overall success of these mechanics.
  4. The Carriere distalizer appliance is a very efficient adjunct to Invisalign treatment that may decrease overall treatment time and provide improved class II correction over using sequential distalization only.
  5. Posterior intrusion with Invisalign for anticipated autorotation of the mandible in high-angle class II cases provides for controlled class II correction .
