Class II: from conventional orthodontics down to aligners and surgery


Ideally, treatment of Class II malocclusions should focus first on improving the skeletal discrepancy using functional appliances while the individual is still growing. However, dentoalveolar compensations, reducing overjet and the severity of the Class II malocclusion, are still the major effect of functional appliances. Due to the questionable functional appliance effect on dentoskeletal growth, quite similar Class II  treatment mechanics may be applied for both growing and non growing individuals.

Nowadays treating Class II, there is a tendency to prefer purely intraoral appliances that require minimal patient cooperation. Biomechanical considerations of treating Class II with the Herbst appliance in comparison with aligners as the only option or a combination of both will be discussed in the lecture.

However, even with the most efficient orthodontic tools it may be impossible to finalize severe Class II cases in healthy condition of the hard and soft tissues of the oral cavity. The reasons of  failure are normally related to the limits of envelope or improper orthodontic bimechanics.

Strong consideration for surgical correction of Class II should be based on the following questions: 1) Does the patient expect improvement in facial esthetics? Even patients who are not particularly concerned with facial esthetics, but who may have a worsening in facial appearance as a result of orthodontic camouflage, should be considered for surgical correction. 2) Can adequate orthodontic correction be achieved not stressing the envelope? 3) May surgical treatment result in a significant decrease in total  treatment time? 4) Is the patient compliant? 5) Are the benefits of surgical treatment obvious comparing to camouflage? Part of the lecture will be devoted to discuss Class II surgical cases and how to discern them from the cases that might benefit from orthodontic camouflage.

Orthodontic challenges of surgical patients


Pre and post maxillofacial surgery orthodontic errors
This course reviews diagnosis, treatment planning, and pre and post surgery orthodontics for combined orthodontic/orthognathic surgery cases. This unique surgical-orthodontic treatment approach is centered on optimal occlusal, joint, and airway function and includes a focus on the best facial esthetic results. Dr. Sampermans will present criteria for successful occlusal treatment, detailing diagnostics, and quality occlusal-facial results. He will discuss the 40 common errors of pre and post surgical orthodontic management and will outline indications and error avoidance using case presentations.
There is a one-day course given by Dr. Sampermans covering the orthodontic problems. The two day course can also be given together with surgeon Professor Dr. C. Politis, Head of the Department of Maxillo-Facial Surgery at Leuven University Hospitals and Professor of Department of Imaging and Pathology, KU-Leuven.

Course objectives

  •  Diagnosis and treatment planning for surgery patient
  •  Classic hard tissue cephalometrics versus soft-tissue cephalometrics
  •  Requirements for starting records
  •  The team approach: the key for successful combined cases
  •  Class III: Camouflage or surgery – Borderline Cases
  •  Correct position of the lower incisor for optimal esthetics
  •  Open bite cases: the surgical approach
  •  Upper incisor torque
  •  Orthodontics after surgery
  •  Surgery first

Midface and mandibular growth modifications in class III and class II orthopedics


Miniplates resist better high discontinuous forces than miniscrews do. Therefore they can be used for intermaxillary orthopedic traction. Class III elastics can be fixed between Bollard anchors on the buttress of the maxilla, and in the canine region of the mandible in young growing patients. Which biomechanical approach should be used, which loading protocol? What is the best timing? Can the growth of the maxilla and/or mandible be stimulated, restric- ted or redirected? The results of this continuous bone anchored traction will be discussed based on Cone-beam CTs at T1 and T2 registered on the anterior cranial base, also in cleft patients. The outcome will be compared with a control group and face mask orthope- dics with or without RPE.






Dalia Latkauskienė graduated cum laude from Kaunas University of Medicine, Department of Dentistry in 1999. After graduation, she continued her studies in Orthodontics at the same university. She obtained her specialist in orthodontics with honors in 2002. Dalia Latkauskiene has applied for Phd degree in 2004 and also continued as a lecturer for postgraduate programs in orthodontics in 2006-2007. She defended her Phd thesis „Herbst- effects on jaws and dental arches in growing Class II patients“ in 2013. Dalia Latkauskienė is currently working as clinical instructor for postgaduate orthodontic students in Lithuanian University of health sciences.



is a graduate of the Ghent University orthodontic program, he received his PhD in 1986 and he maintains a private practice in Brussels. He has been Professor and Chairperson of the Department of Orthodontics at the Université Catholique de Louvain from 1989 to 2006. Currently he’s an Adjunct Professor at the University of North Carolina at Chapel Hill. He received the Dewell Award of the AJO-DO in 2011 and the Jacob A. Salzmann Award of the AAO in 2019. He’s a former President of the Belgian Orthodontic Society and Fellow of the Royal College of Surgeons of England. His main research interests are in skeletal anchorage, biomechanics and orthopedics. He lectured extensively on these topics throughout the world.



Graduated in 1980 as a general dentist from the University of Leuven, Belgium. In 1986 he started his private orthodontic office in Belgium and in 1997 in Heinsberg,Germany. From 2003 to 2010 he led an orthodontic office in Maastricht, the Netherlands. In 2010 he opened a brand new orthodontic office in Echt, the Netherlands. This office is considered a state of the art orthodontic office, including progressive concepts about service and efficiency using the latest digital developments. Dr. Sampermans is an affiliate member of the Angle Society in Southern California (USA) and has taught orthodontic treatment philosophy and orthodontic practice management both inside and outside of Europe for 15 years. He also offers micro-seminars in his office on self-ligating brackets, indirect bonding, computer related 3D technology, and modern practice management. Since 2003, he has been a speaker at 30 orthodontic congresses. He has first-class knowledge and extensive experiences with pre-adjusted appliance systems (Andrews, Roth, MBT, Roncone). He has worked with active self-ligating bracket systems since 2003, finishing over 5000 cases with this system. Dr. Sampermans is a guest lecturer at the post-graduate program at the University of Regensburg, Germany and lecturer at the ZAFI-Institut in Vienna.
