Oral appliances for obstructive sleep apnoea: an evidence-based analysis.
This lecture will focus on the management of obstructive sleep apnoea (OSA) with mandibular advancement devices (MADs). MADs are removable orthodontic devices which protrude the mandible and increase the upper airway patency during sleep thereby diminishing the upper airway collapsibility and elevating upper airway muscle tone. They are increasingly used to treat mild to moderate OSA and those patients with severe OSA who prefer to avoid, or are not appropriate candidates, for continuous positive airway pressure therapy or surgery. This presentation will explore the current status of research in the field.
The following topics will be discussed: cephalometric predictors of treatment outcome, effectiveness of different mandibular advancement amounts, dentoskeletalchanges after long-term and continuous MAD wear.

Snapshots of orthodontic gnathology: the facts from the fiction
Orthodontic treatment often follows gnathologic principles to achieve an ‘optimal’ or ‘ideal’ occlusion and jaw relationship. Often these concepts are
related to function/dysfunction of the masticatory system and are considered as an indication for orthodontic treatment. However, they are not substantiated
by reliable scientific evidence. This is the case also for several claims such as that a good occlusion is important for biting, chewing, speaking,
swallowing, and breathing, and that occlusal anomalies in the form of crossbites or a Class II jaw relationship can be risk factors for temporomandibular
disorders and/or sleep disordered breathing.
This lecture will review gnathologic aspects of orthodontics in an attempt to distinguish fact from fiction around the relationship between occlusal anomalies and jaw function or dysfunction and will endeavour to answer the following questions. What is a good occlusion? Is a good occlusion important for correct jaw function? Are the classic gnathologic principles still relevant to modern orthodontics? What are the red flags to consider before, during or after orthodontic treatment?
The lecture will also address the emerging evidence indicating that the risk of non-adaption to occlusal changes depends more upon neurocognitive aspects than the type or severity of occlusal anomaly.

Can Orthodontics Be Accelerated?
The Index of Orthognathic Functional Treatment Need
Dr Greg Huang received his dental degree from the University of Florida (1987), and then earned a Certificate in Orthodontics and an MSD from the University
of Washington (1989). After 10 years of private practice, he decided to pursue an academic career and accepted a faculty position at the University
of Washington where, concurrently, he also enrolled in the MPH program in epidemiology. On
completion of his MPH in 2001, he began his career as a clinical scientist, and has been involved with many studies, from retrospective investigations to randomized trials. He is a well-known advocate of evidence-based orthodontics, lecturing nationally and internationally on this topic. In 2008, he was named Chair of the Department of Orthodontics at the University of Washington.
Dr Huang is a Diplomate of the American Board of Orthodontics, as well as an Angle Society member. He has published more than 70 articles, and is the co-editor of two orthodontic textbooks: Evidence-based Orthodontics (2011) and
Orthodontics: Current Principles and Techniques, 6th edition (2016). He serves on the Editorial Boards of Orthodontics and Craniofacial Research and Journal of Orthodontics. He has also served as an Associate Editor for the American Journal of Orthodontics and Dentofacial Orthopedics.
Ninety two practitioners and 350 patients from across the United States of America were recruited by the National Dental Practice-Based Research Network for a study of adult anterior open bites. In this lecture, Dr Huang will describe the practitioners' and subjects' characteristics, the practitioners' recommendations, and the patients’ accepted plans. He will also describe relationships that affect recommendations and treatment. For instance, do recommendations vary based on a practitioner’s experience, and are patients with more severe skeletal characteristics more likely to accept surgical treatment? Additionally, some preliminary information will be presented on the success of different treatment modalities.

A closer look at life-long retention
Most orthodontists believe that a truly stable treatment outcome is a myth and that maintaining ideal alignment can only be achieved with some kind of
permanent retention. Preserving incisor alignment is especially important from the patient’s perspective and, for this reason, an increasing number
of orthodontists advocate life-long retention.

Breakthroughs in understanding cleft lip and palate and craniosynostosis: implications for treatment and for orthodontics
I will review some of the dramatic recent advances that have been made in understanding the aetiology of craniofacial anomalies. The normal development of the craniofacial region, including the lips, palate and bones, will be described emphasising the critical stages and the key regulatory mechanisms that can go wrong and result in a craniofacial deformity.
Focusing on cleft lip and palate and craniosynostosis, laboratory examples will be given on how new technologies are being used to unravel the mechanisms of disease. The seemingly insurmountable limitations of correcting the causes of developmental abnormalities that occur before birth will also be described; in addition how understanding the aetiology and characteristics of a developmental condition can be of great benefit to patients.
Dr Maisa Seppala (DDS, MSc, PhD, MOrthRCSEd, FDSOrthRCSEng, FHEA) is a clinical lecturer in orthodontics at King’s College London (KCL) based at Guy’s and St Thomas’ NHS Foundation Trust. She graduated as a dentist in 2002 at Oulu Dental Institute, Finland and undertook a PhD in the Department of Craniofacial Development at KCL. This project, focussed on the regulation of Sonic hedgehog (Shh)signalling by the transmembrane protein Gas1 during craniofacial development. Her research introduced Gas1 as a potential causative gene for the significant human malformation Holoprosencephaly. She has subsequently further investigated the role of genetic modifiers associated with this condition and her current research focuses on how Gas1 regulates dental formula by interacting with Shh and other possible novel signaling pathways. Following her PhD she undertook orthodontic specialist training at KCL, which was followed by an NIHR funded Academic Clinical Fellowship and accreditation as a Consultant Orthodontist.
Searching for the molecular causes of altered tooth number in mouse and man
Development of the dentition is a well-coordinated process, where multiple novel molecular pathways function together to provide the right number of
teeth at the right time and in the right place. Sonic Hedgehog (Shh) is a secreted signalling molecule that plays a crucial role during early tooth
development by inducing proliferation, cell polarisation and by establishing an appropriate morphogenic gradient during cuspal patterning. In the
mouse, defective Shh signalling can result in incisor and molar fusion, whilst over-activity has been associated with supernumerary tooth formation.
In human populations, aberrant Shh signalling can induce a variety of craniofacial anomalies, including maxillary incisor fusion and midline facial
defects. Similarities in mammalian and human genomes and disease phenotypes enable investigation into the causes of tooth anomalies with advanced
molecular techniques, powerful genome sequencing methods and bioinformatics.
This presentation will discuss how genetic screening studies have enabled clinicians to identify new candidate genes associated with variable dental anomalies and how the underlying molecular mechanisms can be further explored by using the mouse as a developmental model.

Does Orthodontic Treatment Improve a Patient's Quality of Life?
The silent revolution within general health has created a paradigm shift from a disease-centred into a patient-centred approach, generating aspects such as oral health-related quality of life (OHRQoL). According to the World Health Organization, health is a state of complete functional, psychological and social wellbeing. Good oral health is more than just absence of disease; the optimal physical, mental and social wellbeing of our patients, is the ultimate focus of our daily practice and research.
In the past, the concept of improving quality of life through orthodontic treatment focused on discomfort, functional problems with eating or speaking and on creating a beautiful smile. Nowadays, the focus does not just concern the oral cavity but the person as a whole, requiring a more subjective, patient-based approach. A person’s OHRQoL is indeed defined by the influence of functional (chewing and speaking, current and past experiences), psychological (appearance and self-esteem), and social aspects (communication, social interaction, intimacy) as well as by a person’s background and cultural upbringing.
This biopsychosocial approach to oral health care requires further investigation to better understand the patient’s expectations and the possible role of malocclusion treatment on function and psychosocial well-being. Numerous investigations are being organized at various phases of orthodontic treatment employing validated scales and questionnaires for this specific purpose. The focus of these long term prospective clinical trials is primarily concentrated on the effect of orthodontic treatment on the OHRQoL both in children and adults, and the possible moderating role of personality traits and self-esteem. Adjunct information may be obtained through gauging the patient’s motivation for treatment and the correlation between their expectations and the final treatment results.
