Title: Collaboration between Paediatric Dentistry and Orthodontics for managing dental trauma cases

In the clinical practice of pediatric dentistry, monitoring the growth and development of the children is part of the anticipatory guidance program, in order to refer them to an orthodontist for the timely management of malocclusion. However, sometimes this collaboration may involve cases where orthodontic management is necessary to complete the dental treatment plan. The cases where this collaboration is most often required are dental trauma cases. For the successful management of traumatized teeth, which present unique characteristics, it is very important for all involved parties to be aware of the factors related to pulp and periodontal tissue healing after trauma, as well as the factors that determine the long-term prognosis following therapeutic treatment. The purpose of this presentation is to discuss the above factors so that the collaboration between paediatric dentist and orthodontist leads to the best possible outcomes.

Title: The bright and the dark sides of Interproximal Reduction

In the history of Orthodontics premolar extractions were the standard treatment option to correct bimaxillary protrusions, severe crowding, and sagittal compensations. With the possibility of bonding and the changes of facial esthetic patterns, interproximal reduction (IPR) became an alternative resource. Even though IPR can, in some cases, be used as a substitute for premolar extractions, two diagnostic factors are of utmost importance to define if and where teeth should be decreased in diameter, namely Bolton discrepancy and dental proportions, most specially in the esthetic zone. Even though, removing healthy dental tissue may be an uncomfortable and an irreversible decision for Orthodontists, currently IPR seems to be swaying as a trend. Clear aligners have stimulated the use of IPR to promote tooth movement, decrease mechanical complexity and reduce collision zones. But adequate diagnosis seems to be disregarded by automated systems, due to needs for tooth movement facilitation. The purpose of this presentation will be to demonstrate clinical parameters in which IPR is indicated for adequate treatment and finishing, discuss the best and most conservative methods for enamel grinding and to illustrate when IPR is absolutely inadvisable.

Pre congress course:
Title: Vertical Problems: Not challenging, just misunderstood

Vertical problems in orthodontics can be present in all types of sagittal malocclusions and are related to the amount of overbite, namely open bites and deep bites. These are generally associated to long and short faces, but this relation is not always present and leads to some misunderstanding in the correction of such conditions. Innumerous combinations of skeletal and dental factors are present in vertical problems and should be analyzed individually and together. This will define if the treatment approach should include surgical, orthopedic or orthodontic treatment only, dealing with changes in the anterior or posterior regions of the arches. Changes in the posterior vertical dimension can also be used favourably in sagittal correction with significant facial changes and alteration in the vertical allocation of anterior teeth can have a significant impact in the smile and speech esthetics. Therefore, the purpose of this presentation is to provide, in the light of current evidence, a guideline of diagnostic factors to be approached when treating the vertical dimension.

After this course, attendees will be able to:

1. establish a checklist of factors to be evaluated for the analysis of vertical problems.
2. define adequate treatment approaches to correct open bites and deep bites.
3. understand the impact of changes in occlusal vertical dimension on the sagittal aspect

Concepts and Controversies in Contemporary Clinical Orthodontics: Everything but the Kitchen Sink

More than lip service for orthodontic controversies (Keynote presentation 45 min.)
Orthodontic treatment “philosophies” and appliance fashions have come and gone as rapidly as fads in the garment industry. Treatments featuring nonextraction, 2-stage, and arch development have again become de rigueur, but not because of convincing evidence of superiority, but rather due to clever, enthusiastic promotion combined with a relentless defamation of extraction treatments. Anecdotal examples of untoward results, punctuated by emotional claims, are more common. Dr. Bowman will discuss the impact of both extraction and nonextraction strategies, based on a comprehensive exploration of the scientific literature, to provide evidence-based guidance in these contentious issues Dr. Bowman’s arguments have been lead to a plethora of articles in the American Journal of Orthodontics and Dentofacial Orthopedics, The Angle Orthodontist, Seminars in Orthodontics, Journal of Clinical Orthodontics, Craniofacial Growth Series, Progress in Orthodontics, Canadian Oral Health, Revista Dental Press de Ortodontia e Ortopedia Facial, Australian Orthodontic Journal, Torq, Journal of Indian Orthodontic Society, OrthoTown, Orthodontic Products, New Zealand Association of Orthodontists Newsletter, and also the cover story for the Journal of the American Dental Association. In addition, Drs. Bowman and Johnston were awarded the Edward H. Angle Research Award for the best research paper published in The Angle Orthodontist in 2000.

1. Distalization: Bad english, good practice. All roads lead to rome for Class II.
2. Uno, Dos, Tres: all the miniscrews in the same place
3. Drastic plastic: improving the predictability of clear aligners
½ Day Seminar (Sunday from 14:00-17:00)

Uno, Dos, Tres: All screws in one place. One concept for three Angle Classes. With the advantage of hindsight, when examining treatments involving the use of miniscrew anchorage, it appears in a parallax view that moving from buccal interradicular insertion of miniscrews to the palate often affords more reliability and versatility for orthodontic biomechanics. Specifically, one palatal insertion site for miniscrews, combined with simple laboratory modifications of transpalatal arches can be employed as anchorage to assist in the correction of a wide variety of malocclusions.

Drastic plastic: Strategies to improve the predictability of clear aligners As the limitations of clear aligner treatments have been identified, conceptualizing techniques and devices to improve the predictability in producing desired results has been the next logical step. A variety of concepts, methods, and adjuncts have subsequently been introduced to enhance the efficacy and effectiveness of clear aligners. Consequently, the scope of biomechanics and type of malocclusions that can be more predictably treated has increased. As one example, the inclusion of miniscrew temporary skeletal anchorage has permitted the addition of direct and indirect anchorage to support and control more predictable programmed tooth movements with aligners.
*The speaker has a financial interest in devices developed for use with clear aligners.

Learning objectives
1) Understand the purpose and advantages of miniscrew anchorage to enhance a variety of orthodontic mechanics.
2) Comprehend the concept of miniscrew anchorage that may enhance the correction of each type of Angle Class of malocclusion.
3) Be familiar with the rationale for the selection of a specific miniscrew insertion site.
4) Understand the purpose and advantages of individualizing clear aligners and applying adjunctive forces to increase treatment predictability.
5) Be familiar with a variety of applications and uses for adjuncts to aligners such as miniscrew anchorage, the addition of buttons/elastics, and enhancement instruments.
6) Realize methods to increase the scope and predictability of clear aligner options.

Title: The use of nanotechnology in Orthodontics

Nanotechnology has become especially popular over the last years in various scientific areas. Currently there are several nanoparticles (NPs) tested in numerous applications. In the medical field, NPs are used not only for diagnostic purposes, but also for therapeutic. With the use of nanodrug delivery systems, personalized medical treatment has shown encouraging results. Likewise, in dentistry and orthodontics, the incorporation of nanotechnology in material science, diagnostics and treatment starts to evolve. In orthodontics, antimicrobial NPs have been used to enhance the antimicrobial properties of orthodontic materials and overcome the problem of microbial accumulation in patients with orthodontic appliances. However, the knowledge around NPs needs to progress since there are several challenges that need to be dealt with. The amount of research that remains to be carried out in this new area is extensive and the future results seem to be of paramount significance. The aim of this presentation is to introduce up to date information on the use of nanotechnology in the field of orthodontics.

Title: Orthodontic treatment with clear aligners: modern developments and prospects

Sponsored by Ariston Dental

Since the introduction of orthodontic treatment with clear aligners in the early 1990s, the use of clear aligners has increased significantly, particularly among adult patients. A large number of companies have developed different aligner systems, and combined with the aggressive marketing strategies of manufacturers, orthodontic treatment with clear aligners has become one of the most popular and rapidly evolving fields in dentistry. However, several aspects concerning key parameters of orthodontic treatment with aligners still remain unclear. An in-depth discussion will be presented on the ongoing clinical challenges associated with clear aligner therapy, alongside a comparative evaluation of existing aligner systems. The presentation will explore the forces exerted by clear aligners during treatment and examine the mechanical properties of the thermoplastic materials used across different systems. Additionally, it will assess the clinical effectiveness of clear aligners in comparison to traditional fixed orthodontic appliances and investigate the changes that occur on the surfaces of attachments utilized in aligner-based orthodontic treatments.

Presentation Title
Excellence in Orthodontics: the power of teamwork

The clinical orthodontic practice is now part of 4 handed dentistry. In the modern orthodontic practice, the contribution of the dental assistant to the improvement of the quality of services is. indisputable. Today, the orthodontic assistant must be sufficiently qualified and familiar with all modern orthodontic techniques. The theoretical training in the specialty of Orthodontics aims for the assistants to be able to successfully fulfill the clinical and secretarial requirements of an orthodontic office. Specialized orthodontic assistants should recognize the basic orthodontic malocclusions, be familiar with orthodontic instruments and appliances (fixed and mobile), have an in-depth understanding of the steps involved in clinical orthodontic procedures, and finally be in position to communicate with patients and parents and explain the procedures and goals of
orthodontic treatment.

Title: “Congenital and acquired mandibular asymmetric hypoplasia: controversies in the timing and efficacy of treatment during growth”.

Long-term results after orthopedic treatment of mandibular asymmetric hypoplasia and craniofacial microsomia (CFM) have not shown any significant improvement of asymmetry. Distraction osteogenesis in growing CFM patients has shown early recurrence. However, the literature contains several successful case reports that show surprising changes in the morphology of the condyles after functional appliances (FA) or distraction osteogenesis (DO). The phenotypes of these cases are unexpectedly similar, with a consistent collapse of the condyle against the coronoid and a deep sigmoid notch and no muscular hypoplasia on the affected side. The objectives of this presentation is to help distinguish true CFM from condylar-coronoid collapse patients (CCC), misdiagnosed as CFM, which are possibly secondary injuries of the condyle, with a normal functional matrix. CCC asymmetries, with growth and functional stimulation, tend to grow toward the original symmetry, similarly to mandibular fractures during early childhood. To make a differential diagnosis between true CFM and this peculiar type of hemimandibular hypoplasia, the collaboration between orthodontists and surgeons, but also geneticists and dysmorphologists, is of great importance because of the different prognoses and treatment approaches. Embryology and embryopathology are fundamental for the understanding of the biology underlying asymmetric mandibular hypoplasia, and their treatment planning.

Title: “Tooth-on-a-chip” devices as models for the simulation of human dental tissues

Translation of preclinical results into effective cell-based therapies remains poor, highlighting the need for accurate human-emulation systems. Recently, 3D in vitro systems containing an essential number of stem cells and other cell populations, which allow the recreation of similar in vivo conditions, have been successfully generated. Miniaturised “organ-on-chip” devices are based on recent technological advancements in microfluidics. These devices successfully emulate human pathophysiological conditions of specific tissues and organs in vitro. They also represent valuable tools for studying the effects of novel pharmaceutical products and materials on dental tissues before their clinical application. Microfluidics have been used for the first time to analyse the role of innervation and vascularisation in dental tissues. These devices are also important in understanding the interconnection of teeth with other organs and studying their responses to the various dental pathologies upon bacterial attack. These new biotechnological platforms are revolutionising dentistry and promise improved dental care. In this lecture, these novel findings will be presented.

Title: Craniomandibular Disorders and Orthodontics

Craniomandibular disorders (CMD) encompass a collection of musculoskeletal and neuromuscular problems that result in functional impairment and pain. The influence of occlusion in the etiology of CMD has been extensively challenged for years.

Despite the extensive research on CMD, a significant disagreement persists among numerous researchers and so-called experts about topics from etiology to treatment methodologies. A comprehensive and thorough understanding of all aspects of TMD is still inadequate

On the other hand, an increasing number of adult patients seek orthodontic treatment for aesthetic reasons or to enhance other dental treatments required for the management and restoration of function. It should be noted that adults have a higher frequency of CMD and a lower adaptive capacity of their Stomatognathic System compared to children and adolescents, resulting in a greater likelihood of experiencing or developing local or systemic pathologies during or after orthodontic treatment.

It is essential for orthodontists to develop the diagnostic ability required for the differential diagnosis of CMD, to comprehend the relationship between occlusion and CMD, accordingly to the current research findings, as well as the possible implications of orthodontic treatment on CMD issues.

TITLE: “Implementing the essential regulatory provisions from the national and EU legal frame work regarding the function of the contemporary orthodontic office.”

The aim of the presentation is to encode the basic information regarding the application and skills that are required by the dental assistant of a contemporary orthodontic office in the light of a continuously amending legal framework. Considering that the clinical orthodontic practice is now part of four (4) or more handed dentistry, the contribution of the dental assistant to the improvement of the quality of services is indisputable. The orthodontic assistant must be sufficiently qualified to fulfill the clinical, secretarial duties and poses communication skills to handle the patients, the parents and the office associates. There is a procedural approach in shaping the dental assistance’s profile in Greece.

We will report, for example on the General Data Protection Regulation (2016/679/EU), on the European Health Data Space Regulation, the Medical Device Regulation (2017/715/EU) regarding medical devices, the Greek Dental Code of Ethics, the application of teledentistry, the framework of the “European Green Deal” which is enforcing a circular economy, the National Electronic Patient Record etc.
