When is the time for orthodontic tooth movement after periodontal treatment?

Periodontal health is a sine qua non condition before any orthodontic treatment. Defining health and healing outcomes after periodontal treatment for gingivitis and early-stage periodontitis patients might be more straightforward. However, this is definitely not the case for advanced stages and grades of periodontitis cases. When is the time for orthodontic tooth movement after periodontal treatment? In this talk, the current concepts of health and periodontal stability, periodontal therapy endpoints, and the timing to achieve them based on the biology of periodontal wound healing will be explored, trying to answer this question.

Plastic Predictability Pearls: Improving the Predictability of Clear Aligners

I like predictability because I know what I’m getting into. – Actress, Katherine Heigl

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. As a consequence, 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. In addition, specific instruments have also been developed to facilitate the individualization of aligners to apply specific forces.*

Objectives:

At the completion of this seminar, the orthodontist will:

1. Understand the purpose and advantages of individualizing clear aligners and applying adjunctive forces to increase treatment predictability.
2. 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.
3. Be able to prepare a streamlined process for enhancing the clear aligner treatment planning process to incorporate individualized modifications for each patient.
4. Increase the scope and predictability of clear aligner options.

*The speaker has a financial interest in devices developed for use with clear aligners.

Extreme impactions – top ways to make better decisions

Orthodontic treatment of impacted teeth cannot be a “cookbook”. Although the results can be excellent, treatment is complicated and usually long. One or several surgical interventions are usually necessary. Most patients are young children or adolescents who need to cooperate with occasionally painful procedures. There are many possible reasons which  may lead to treatment failure, such as inaccurate positional diagnosis, missed resorption of adjacent teeth, inappropriate mechanotherapy, surgical mistakes and  the risk of failure increases with the severity of impaction. In this presentation, several difficult impaction cases will be exploited to illustrate the step-by-step decision-making process which may help the clinician make the most thoughtful treatment decision, highlighting the importance of early diagnosis, gathering of comprehensive pretreatment data, assessing treatment alternatives, weighing the evidence, and critically reviewing the decision and its consequences.

Using Your Fixed Appliance – Can you Reduce Treatment Time With Gimmick-Free Orthodontics?

There is currently significant interest amongst orthodontists and patients in reducing orthodontic treatment time, particularly when using fixed appliances. This has spurned an increasing number of adjunctive techniques designed to speed up tooth movement. These are wide-ranging but include different surgical procedures that can represent a significant level of clinical intervention. This lecture will discuss the evidence base relating to orthodontic tooth movement using data from a recent systematic review and discuss those factors that can influence how quickly teeth move with fixed appliances. We will then consider whether adjunctive techniques can really influence how fast teeth move over the longer-term and present some preliminary results from a randomized clinical trial investigating the impact of appointment intervals on tooth alignment. Finally, we will consider whether there are some less exotic techniques available to maximize orthodontic tooth movement and reduce treatment time when using a fixed appliance. What simple things can we do to minimize the length of time our patients have to wear their braces? All the data discussed in this lecture will be evidence-based.

Bone anchored maxillary protraction: an update

In the last decade, growing patients with Class III malocclusion have been increasingly treated with bone-anchored maxillary protraction. Several protocols have been described, but they can generally be divided into two categories: 1) intermaxillary elastics are engaged on skeletal anchorage devices and on a facemask, with miniplates only in the maxilla and 2) class III elastics are engaged between skeletal anchorage in both maxilla and mandible, without the use of a facemask. The lecture will detail the different protocols used, and focus on the evidence available, comparing the clinical outcomes obtained with bone anchored maxillary protraction, with and without facemask.

Dr Oyku Dalci

Her research interests include Class III orthopaedic treatment, Obstructive Sleep Apnea, orthodontic mini-screws,orthodontic tooth movement and root resorption. 

Contemporary Skeletal Class III Treatment

Skeletal Class III malocclusion is one of the most challenging orthodontic problems to treat. The most widely used conventional Class III orthopaedic treatment is face mask, which relies heavily on patient compliance, with varying degrees of success. Over the years many contemporary orthopaedic treatment methods have emerged to overcome the difficulty in managing skeletal Class III patients, directed at disarticulation of sutures, skeletal anchorage and patient compliance. This presentation is going to discuss the current evidence on these methods with a focus on intra-oral, mini-screw anchored orthopedic appliances.

Accelerated Orthodontic Tooth Movement; Do we need external Aids?

The only way to accelerate orthodontic tooth movement is to accelerate bone resorption via biological response from the periodontal ligament in response to mechanical loading. In fact the question to be asked is :“Can we accelerate bone resorption ?” Multiple methods, including drugs and external stimuli were tested over the years at the University of Sydney. Some methods were promoted by companies usually with little or no evidence.
The lecture will address all available methods utilised to accelerate orthodontic tooth movement, discussing results of experimental studies, their clinical significance and whether these methods can cause any harm to dental structures.

Orthodontic Retention: Not letting go?

While there is widespread acceptance of the necessity for indefinite retention to mitigate post-treatment change, there has been relatively little prospective research concerning the relative effectiveness of fixed and removable retention protocols in the longer term.

Prolonged outcomes with fixed and removable regimes will be discussed on the basis of a recent randomised controlled trial with 4-year follow-up. Patient experiences associated with retention, including factors influencing compliance with removable retention will also be presented.

Finally, iatrogenic effects associated with fixed retention will be considered. Practical solutions to mitigate these potential issues will be presented coupled with illustration of techniques used to manage particularly unstable situations.

How long is too much? The minor’s experience

Class III malocclusion, when identified early, presents to us a significant dilemma: To treat or not to treat? The unpredictability of mandibular growth makes it challenging to have a high degree of certainty on the likely outcome of early intervention. Nevertheless, the potential of minimizing the perceived need for future orthognathic surgery is a carrot that very few parents would not seriously contemplate. This short presentation will showcase two cases managed with a skeletal anchorage that could be considered successful after a long winding journey. In both cases, knowing what they now know, the now adolescents would have preferred the late intervention, including surgery. An analysis of pertinent related published evidence will be presented as well as the discussion of the burden of care concept and our understanding of informed consent processes with minors. This talk may challenge your perception of the timing of what you are currently doing. To treat or not to treat is the question.

Factors to increase the efficacy of Class II and Class III treatment

This lecture will analyze patient-related factors that can help the clinician to improve the efficacy and efficiency of Class II and Class III treatment independently from the type of appliance. Two such factors are the timing of treatment and individual patient responsiveness. Functional appliances used for the treatment of Class II malocclusion are effective in altering short-and long-term mandibular growth and mandibular sagittal position if active treatment includes the pubertal growth spurt. Optimal timing for Class III malocclusion occurs during the prepubertal phases of development when the circummaxillary sutures offer less resistance to maxillary protraction compared to the pubertal phase. To predict individual patient responsiveness for both Class II and Class III treatment, mandibular morphology should be evaluated.

Applications of 3D Metrology in Orthodontic Research

The use of metrology software has been shown to have an application in aligner research to quantify treatment changes by looking at shortfalls in planned tooth movements. A detailed analysis of individual tooth movement shortfalls between predicted and actual outcomes is possible using the applications of this technology. Advantages include provision of highly accurate analysis without the need for additional radiation associated with imaging such as CBCT.

Malocclusions treated with aligners often fall in the mild to moderate categories of severity. As such traditional methods of evaluating orthodontic treatment outcomes such as the PAR index, which measure the difference between the post-treatment and pre-treatment scores, may not be the most  meaningful method for evaluating treatment results and specifically which tooth movements have not expressed as planned.

Metrology software has been widely used for the assessment of 3D tooth models generated from intraoral scans. GeomagicRControl X™ software (3D systems, NC, USA) has been utilised in recent studies for the assessment of planned changes in overbite, labio-lingual crown angulation, incisor rotations, occlusal contacts and in the curves of Spee and Wilson.

Models of the same arch taken at different time points can be superimposed using GeomagicR Control X™ software to assess the precision by which the achieved outcome matched the intended outcome as prescribed using the pretreatment digital plan. Digital models can be analysed using direct measurement of differences, by qualitative visual comparison of superimposed models, 2D slices and 3D heat maps

Digital Pathways in Implant Dentistry – Clinical Considerations when Moving into the Digital Realm

The evolution of digital technology in implant dentistry is developing at a rapid pace. The mainstream availability of three dimensional imaging with CBCT has been a turning point in providing safety and predictability in dento-alveolar surgery, as well as providing a platform for restorative input into the treatment planning process. This has been followed by a surge in the fields of virtual implant planning, digital intra-oral scanning, 3D printing and CAD/CAM restorations. However, is this technology absolutely necessary? And are we utilizing it to its full potential?

This lecture will explore the various technologies which can be integrated into the digital implant workflow with a clinical and evidenced-based approach to the advantages and disadvantages of each.

Digital treatment planning to treat complex Class III cases with aligners.

Digital treatment planning is a valuable tool in the planning of orthodontic tooth movement. This is especially so in Class III occlusions where the control of the vertical, anterior-posterior, transverse and angulation of the anterior teeth is crucial. Aligner treatment has become a favoured orthodontic appliance by both patients for their great aesthetics and comfort, but also for the Orthodontist as they offer excellent control of tooth movement.

Total arch intrusion for hyperdivergent Class II face: an alternative to conventional orthopedics

Vertical excess of the facial dimension is common and can be expressed in various ways-gummy smile, lip incompetency and/or retrusive mandible. Due to the genetic nature of the vertical growth, however, it has been recognized as very challenging to correct the hyperdivergent face. A latest meta-analysis revealed the lack of clinical evidence in the vertical control using conventional appliances including high pull head gear. In contrast, our recent clinical & experimental studies revealed the possibility of total arch movement according to the force direction with regard to the estimated center of resistance of entire dental arch. Therefore, replacement of orthopedics using reliable total arch intrusion using miniscrews is inspiring. In this session, the biomechanics, clinical effects and stability of vertical control using total arch intrusion will be explained in the aspects of etiology, protocols and stability in Class II, III and asymmetry cases. Additionally, the rationale and possibilities of radical root movement of lower incisors leading to ‘symphyseal remodeling’ in children with hyperdivergent face will be demonstrated

What drives the future of orthodontics?

The world is changing rapidly and Orthodontics is evolving along with it. The pace of change has left many orthodontists feeling uncertain and perhaps even afraid of what the future will hold. Technological advancement, economic pressures, increased competition, chatter from social media and shifts in marketing all help to accelerate change. It is clearly established that most patients seek orthodontic treatment because they want their teeth and their smile to look better. Social pressures shape the perceptions of patients as to how they should be treated and consequently act to influence how we treat patients. Is it appropriate to set goals for orthodontic treatment if there are no confirmed detrimental effects caused by not meeting them? What do our patients expect from the orthodontic treatment they voluntarily seek, and how willing are they to accept compromises? The answers to these questions may very well shape the future of orthodontics as we adapt to a changing environment.

You can listen to a Regional ABC Interview with Dr McCarthy recorded in 2015 as part of the Dr Who Series on periodontal disease and risk factors, symptoms and treatment. Her special interests include paediatric periodontics, treatment of periodontal diseases, gingival recession, periodontal plastic surgery especially gingival grafting and pre-orthodontic surgery.

Long Haul Gum Grafts

Maintenance of periodontal attachment underpins successful orthodontic treatment.  Periodontal attachment loss, presenting as gingival recession, can occur rapidly especially in patients with a thin phenotype, with a lack of attached gingiva and high frenal attachments.  Thorough pre-orthodontic periodontal risk assessment is essential and referral for gingival augmentation at certain sites can predictably prevent attachment loss.  Should attachment loss occur during or post orthodontic treatment, certain gingival grafting procedures can offer long term solutions for root coverage.  Not all patients with thin tissue require gingival augmentation.  Not all teeth are equally susceptible to attachment loss occurring.  Those sites at greatest risk of recession following predicted orthodontic tooth movements and arch expansion should be considered for pre-orthodontic grafting.

This presentation will answer

  • Which patients and which sites are at risk?
  • What happens if you do not graft?
  • Is gingival grafting necessary and which technique will provide the best solution?
  • Do grafts last and provide benefit in the long term, beyond completion of the orthodontic treatment?

3D evaluation of the tongue and oral cavity before and after orthognathic surgery for mandibular prognathism

The ratio of the tongue volume (TV) to the oral cavity capacity (OCC) was recognized to be an important factor for the maintenance of a stable dental arch shape and proper occlusion. However, the volumetric changes of the oral cavity including the tongue before and after surgery has yet to be fully elucidated. TV and OCC have been successfully measured by cone beam computed tomography (CBCT) although its drawback is radiation exposure of the patients. Therefore, we developed a method to evaluate the morphological and volumetric changes of the tongue and the oral cavity following orthognathic surgery by using a vinyl polysiloxane impression method (VPS method). With this method, morphological evaluation of the tongue and oral cavity could be performed at any stage of the surgical-orthodontic treatment with no concern about radiation exposure.  More recently, we established a method to visualize the changes of the tongue movement before and after orthognathic surgery in patients with mandibular prognathism by superimposing ultrasound video imaging and lateral cephalogram.  In this presentation, evaluation of the changes of the tongue posture and movement in the oral cavity before and after orthognathic surgery for mandibular prognathism with non-radiological techniques will be discussed.

Clear aligners – Are we there yet?

In a time of uncertainty, one aspect of orthodontic practice that is guaranteed, is the increasing use of clear aligners as a treatment modality. However, because of the continual development of digital orthodontics and the ever increasing number of clear aligner supply companies, it is hard to keep pace as to what is best practice. This is particularly true as we function in an environment where clear aligner product changes/commercial changes outpace the generation of research assessing treatment efficacy. This presentation provides a brief summary of the current evidence on the efficacy and efficiency of orthodontic treatment using clear aligners. The intention of this presentation is to facilitate evidence based practice by clinicians who employ clear aligners in their “day to day” treatment of patients.

Anatomic assessment and functional simulation of the upper airways in the digital era; what can we achieve with Rapid Maxillary Expansion (RME)?

Rapid maxillary expansion (RME) is used to treat transverse maxillary deficiencies imparting significant skeletal and dentoalvoelar effects. RME treatment and its impact on the upper airways has received increased interest showing positive effects on its dimensions and function. Several RME designs have been implemented to enhance the desirable effects in both skeletal and airway parameters while reducing dentoalveolar side effects such as tooth tipping and alveolar bending. The upper airway has been traditionally measured by orthodontists using 2D lateral cephalograms with the inherent limitations. Advances in 3D imaging have allowed better visualization and reliable analysis. The aim of this presentation is to discuss the upper airway anatomical and nasal ventilation changes induced by RME using current technological advances in the imaging and assessment of the upper airway areas of interest. The correlations between anatomical and functional breathing changes as well as the resolution of upper airway obstructions will be related to different RME appliance designs anchored either on teeth or alternatively on temporary anchorage devices (TADs).

Root Resorption: A 2022 Update for The Clinician 

This presentation will answer the six most commonly asked questions about root resorption and orthodontics: 

  1. Should I move teeth with short roots? 
  2. Can I predict which patients are at risk of severe external apical root resorption (EARR?) 
  3. What do I do when I see EARR at progress? 
  4. Is there less resorption with new techniques and devices such as clear aligners? 
  5. What does root resorption look like on a cone beam CT scan? 
  6. What happens to teeth with short roots long term – are they at risk of eventually falling out?

The answers to these important questions will be provided by the author of the only book solely dedicated to orthodontic root resorption in this fast-paced presentation.

Anterior Open Bytes: New Techniques to Closing Anterior Open Bites using TADs and Aligners

With advances in TADs and clear aligner therapy, orthodontists have more options to treat anterior open bite and vertical maxillary excess patients. This lecture will focus on the mechanics and results using clear aligners with or without TADs to treat the vertical dimension of these difficult types of malocclusions. The stability and retention to control the vertical will be covered. The results and stability of closing anterior open bites using clear aligners with TADs vs fixed appliances with TADs vs surgery will also be compared.

Overcoming aligner limitations by using mini-implant borne sliders and expanders

An increasing number of patients seek orthodontic treatment with aligner therapy. Bodily tooth movement with aligner therapy is challenging when relying on aligners alone. Whilst there are limited reports of successful bodily molar movements of up to 1-2 mm in the literature, a very long treatment time and high level of patient compliance and is expected. Moreover, the potential side effects of intermaxillary elastics must be considered in terms of shift of the anchorage teeth; this might be a severe problem especially in unilateral elastics applications with the potential for development of a midline shift, arch rotation and a jaw discrepancy, and transverse occlusal canting. To avoid this anchorage loss and the high demand on elastic wear, orthodontic mini-implants may be used. Currently, the alveolar process is still the most preferred insertion site for mini-implants. However, due to a failure rate and the risk of root damage, insertion in the alveolar ridge is far from satisfactory. Other regions such as the anterior palate provide much better conditions for the insertion and stability of skeletal anchorage devices, as the amount and quality of the available bone is far superior. In this lecture, the combination of mini-implant-borne appliances and aligners is presented to achieve more predictable and faster results in aligner therapy.

Long Term Effects on Alveolar Bone with Bone-Anchored and Tooth-Anchored Rapid Palatal Expansion

The purpose of this study was to evaluate the long-term effects of bone anchored. and tooth-anchored expansion appliances on alveolar bone in vertical and. horizontal dimensions in comparison with controls using Cone Beam Computed Tomography (CBCT). Materials and Methods: We evaluated180 CBCTs for 60 patients at three time-points T1 (pre-treatment), T2 (post-expansion), and T3 (post-treatment) for three groups: i) Bone-Anchored expansion appliance (BA), ii) Tooth-Anchored expansion appliance (TA), and iii) Controls. The intermolar width, molar angulation, palatal width, vertical bone height, buccal bone thickness at alveolar crest and root apex were measured in the three groups at different time-points. Results: In the short-term, both BA and TA led to a statistically significant increase in the intermolar width, and vertical bone height following expansion in comparison with controls, though the vertical bone height was significantly greater in TA compared to BA. Additionally, TA led to significantly increased molar angulation (buccal tipping) when compared with controls at T2. In the long-term, there was no significant difference in the three groups except vertical bone height, which was significantly greater in TA compared to the control group. A substantial correlation was found between molar angulation and vertical bone height and a moderate negative correlation was found between intermolar width and buccal bone thickness at alveolar crest at T3. Conclusions: There was no difference in the treatment outcomes between the three groups in the long-term except vertical.
