Retention - what is the evidence of how to retain our orthodontic treatment?
Dr Simon Littlewood
Chair of the Membership in Faculty of Dental Surgery Exam for the Royal College of Surgeons, England
Speaker Bio
Dr Littlewood has been working as a Consultant Orthodontist in the UK for over 20 years, and over this time has developed a fascination with orthodontic retention.
He has published several book chapters and scientific articles on the topic, and has been invited to lecture in over 25 countries on the topic.
Dr Littlewood is currently the Honorary Secretary of the British Orthodontic Society, Co-Director of the Yorkshire Orthodontic Therapy Course and Chair of the Membership in Faculty of Dental Surgery exam for the Royal College of Surgeons of England.
He is also co-author of the best-selling textbook, “An Introduction to Orthodontics”. He is well-known as an entertaining presenter who aims to present the findings of high-quality research in a way that is relevant to busy clinicians.
Learning Objectives
- Understand the best contemporary evidence involving removable and fixed retainers.
- Be aware of evidence supporting how often retainers should be worn, possible side-effects of retainers and patients’ perceptions of different approaches to reducing post-treatment changes.
Abstract
Retention remains one of the most important, yet complex areas in Orthodontics. Due to the long-term nature of post-treatment changes, research into retention is challenging, and as a result high-quality evidence has been limited. In the last Cochrane Review “Retention procedures for stabilising tooth position after treatment with orthodontic braces” in 2016 by Littlewood et al, 15 randomised controlled clinical trials (RCTs) were identified. Just 6 years later there are now over 40 RCTs involving retention, helping to provide clinicians with more information and certainty into different ways of reducing unwanted post-treatment changes after treatment. In this presentation, Dr Littlewood will discuss the best available contemporary evidence comparing different types of fixed retainers, different types of removable retainers, how often retainers should be worn, as well as comparisons between removable and fixed retainers. The talk will look at different techniques, including the evidence behind CADCAM retainers, different materials, side-effects and patient perceptions.
Expansion and compression archwires for posterior crossbite correction in adult patients
Professor Dirk Wiechmann
Professor of Orthodontics at Hannover Medical School, Germany
Speaker Bio
Professor Wiechmann, Dr. med. dent. Dr. h.c., received recognition as a specialist in orthodontics in 1997. He has been in private practice since 1998 in Bad Essen, Germany, the largest lingual practice in the world with about 1000 lingual patients in active treatment. In 2011 he completed his ‘Habilitation’ in orthodontics. Since 2013 he has been professor of orthodontics at Hannover Medical School. Germany. In 2016 he received the Doctor Honoris Causa from the University of Montpellier, France.
Professor Wiechmann has received several prizes and honours for his scientific work in the field of orthodontics, including the honorary prize of the French Federation of Orthodontics.
The focus of his scientific activity is lingual orthodontics.
Learning Objectives
- To understand that the reason for a posterior crossbite may be an enlarged mandibular arch
- To learn how to fabricate expansion and compression archwires
- To understand the limits of dentoalveolar compensation
Abstract
Posterior crossbite is a frequent finding in adult orthodontic patients. In most of the cases we can diagnose a combination of a constricted maxillary arch and an enlarged mandibular dentition. Nevertheless, in current concepts the treatment approach mainly targets the maxillary arch only, with sometimes important expansion protocols. Particularly in adult patients, these protocols often require a surgical assistance (SARPE). Recently, expansion and compression SS archwires were introduced as an option in treatments of a posterior crossbite with completely customised lingual appliances.
The aim of this study was to compare the amount of posterior crossbite correction with surgically assisted rapid palatal expansion (SARPE) versus a non-surgical transversal dentoalveolar compensation with completely customized lingual appliances (CCLA). The surgical group (n = 43; f/m 19/24; mean age 27.6 ± 9.5 years) was treated with SARPE and buccal straight wire appliances. The non-surgical group (n = 38; f/m 25/13; mean age 30.4 ± 12.9 years) was treated with completely customized lingual appliances (CCLA).
Results: There was no statistically significant difference (p > 0.05) in the amount of total crossbite correction between the SARPE and the CCLA group in the posterior segment. Maxillary expansion was greater in the SARPE group and mandibular compression was greater in the CCLA group. Crossbite correction in the CCLA group was mainly a combination of maxillary expansion and mandibular compression.
Conclusions: Dentoalveolar compensation with CCLAs as a combination of maxillary expansion and mandibular compression seems to be an effective concept to correct a transverse maxillo-mandibular discrepancy.

Learning Objectives
Identify the relative success of aligners in achieving the predicted tooth movement for a variety of types of movements;
Understand the limitations and their origin of current aligner systems in producing the required movement
Recognize the potential of adjuncts of aligner treatment to enhance or improve treatment efficacy.
Abstract
The issue of efficacy of aligner mechanics has recently been the focus of a number of studies which basically report discrepancies between predicted and achieved outcome identifying types of movements which still pose a challenge for aligners. The purpose of this lecture is to summarize the evidence pertinent to relative efficacy of aligner treatment in achieving predicted tooth movement either based on software data or comparison with the treatment outcome achieved by other appliances. Potentially underlying mechanisms of the discrepancies noted are discussed, whereas future appliance construction, material development, and/or adjuncts to aligner treatment are presented.
