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.

Biotype and the development of gingival recession in orthodontic patients.

A correct diagnosis of the biotype is considered important with respect to decision making in clinical dentistry. For instance, the outcomes of periodontal therapy, conventional prosthodontics, implant therapy and root coverage procedures are regarded as related to gingival biotype. Also in orthodontics, the assessment of gingival biotype might be important – several recent systematic reviews of the development of gingival recession in orthodontic patients implied that the biotype could play a role in its development.
In the lecture, the relationship between gingival (or, more generally, periodontal) biotype and periodontal status during orthodontic treatment and after orthodontic therapy will be discussed.

Can Orthodontics Be Accelerated?

Contemporary orthodontic practice appears to be influenced by many technique related factors such as the type of appliance, adjunctive surgical procedures and technological processes. Increasing the speed of the treatment process has received significant attention, yet the fundamental decision processes in planning treatment that is customised for that specific patient, rather than a universal application of a technological process, has not been well investigated. The key decision making processes to achieve success from the clinician and patient perspective will be discussed. The selective use of efficient mechanics, surgical interventions and temporary anchors will be explored and demonstrated, with a discussion of the evidence to support/refute the purported mechanisms to enhance the overall speed of orthodontic treatment.

The Index of Orthognathic Functional Treatment Need

In recent years, within the United Kingdom (UK) National Health Service (NHS) , there has been a drive to reduce costs; not only to reduce overall spending, but also to divert money and resources away from what are deemed 'low priority' treatments. However, within different areas of the UK there has been no universal acceptance of what is deemed 'low priority'. What is considered low priority in one area might automatically receive funding in another, leading to the potential for a postcode lottery of health. This was certainly the case with orthognathic commissioning, with some commissioning areas deciding to withhold funding, whilst others were prepared to continue funding treatment for functional reasons, provided patients were also categorised as Index of Orthodontic Treatment Need (IOTN) 4 or 5. However, IOTN has limitations as a measure of functional and health need in orthognathic treatment provision, such that some severe dentofacial deformities and malocclusions would not be eligible for NHS funding. In order to overcome these limitations the Index of Orthognathic Functional Treatment Need (IOFTN) was developed. This lecture will chart the development of the IOFTN from its inception to its current use.

Management of Adult Anterior Open Bites

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.

Treatment effectiveness and quality of the results using lingual orthodontics

The 1970s provided orthodontics with the lingual approach to treatment management. From the concept of bonding a labial bracket on the lingual surface of a tooth, CAD/CAM technology now brings state-of-the art individualization of lingual bracket design and archwires: a completely customized lingual appliance fabricated for each patient and a set-up displaying the expected treatment outcome.
This presentation will deal with the specificities of lingual biomechanics - why customization is necessary and the benefits of using such appliances. Furthermore, through clinical cases, treatment management will be explained. This lecture will address more specifically Class II malocclusion correction with or without extractions, involving either intermaxillary elastics, bite jumping devices or temporary anchorage devices.
The clinical efficiency of customized lingual orthodontics exceeds the simple alignment of permanent teeth in adults and adolescents.

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.

This lecture will focus on important questions related to fixed retention, and will clarify whether life-long retention is achievable and advisable. Different bonding procedures (acid-etching with or without sandblasting) will be evaluated and the materials used for fixed retention will be reviewed, with particular emphasis on their mechanical properties, the intra-oral ageing process and their biological reactivity. Some clinical suggestions for improving the bonding protocol and for the correct choice of materials will be made, and their evidence-base examined.
The effectiveness of bonded retainers will be assessed and their performance validated by a review of published failure rates. The long-term effects of bonded retainers on dental and periodontal tissues will be highlighted, and the significance of oral hygiene discussed. Unwanted tooth movements associated with bonded retainers will be described, and recent evidence substantiating the probable underlying mechanism discussed. These findings will be presented together with their clinical implications and relevance for long-term retention management. The conveyed insights intend to provide a fresh outlook on post-orthodontic patients.

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.

EOS 2018 - Speaker - Maisa Seppala

Maisa Seppala


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.

Dr Seppala has presented her research at national and international conferences and has published in a number of significant journals, including the Journal of Clinical Investigation and Development. Her current research is funded by the European Orthodontic Society and the United Kingdom Academy of Medical Sciences.


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.
