Why tooth movement acceleration fails: Cortical boundaries and tissue constraints
-
Prof. dr. Yijin RenOrthodontist, Groningen, The Netherlands
- Current evidence indicates that measures aimed at accelerating orthodontic tooth movement (OTM), whether surgical or non-surgical, have not demonstrated clinical benefits beyond the short term.
- This lecture will explore the constraints underlying OTM, focusing on two key factors:
the biological threshold—how fast can we realistically move teeth
the cortical boundaries—what is the adaptive capacity of the alveolar housing as teeth are moved within the alveolar socket? - The lecture will discuss a biological framework to better understand the constraints and limits of OTM.

The honorary BSSO lecture by Patrick Kemperman & Nienke Vulink
Delusional perceptions in orthognathic care: From BDD to delusional infestation
-
Patrick Kemperman -
Nienke Vulink
1. When the complaint outweighs the clinical findings
Disproportionate distress, preoccupation or conviction may point towards BDD or a delusional disorder rather than a problem that can be corrected surgically.
2. The patient’s conviction is a clinical clue.
Explore not only what the patient sees, feels or believes, but also how certain they are, how much time it occupies, and how it affects daily functioning.
3. Know when not to operate.
In BDD and delusional infestation, repeated procedures, investigations or attempts to “fix” the perceived problem may reinforce the disorder and lead to dissatisfaction, further treatment-seeking and harm.
4. Do not fight the belief, build an alliance.
Acknowledge the patient’s suffering without validating an unsubstantiated explanation. Curiosity, empathy and a non-confrontational approach create the opportunity for appropriate treatment.
5. Recognition is an intervention.
Early identification of BDD or delusional infestation, followed by collaboration between MKA surgeons, dermatologists and mental-health professionals, can prevent unnecessary procedures and change the patient’s trajectory.

Hakan Tuz
Multi-dimensional perspective in maxillofacial asymmetry correction
-
Hakan Tuz
Facial asymmetry is a three-dimensional challenge that extends well beyond correction of the dental and skeletal midlines. Its consequences include occlusal canting, uneven facial contours, malocclusion, impaired mastication, temporomandibular joint dysfunction, airway compromise, and psychosocial burden. Comprehensive assessment therefore requires simultaneous evaluation of the skeletal framework, soft tissues, muscles, condyles, and airway. Three-dimensional CBCT, intraoral scanning, and stereophotogrammetry enhance diagnostic accuracy, while virtual surgical planning, surgical guides, and patient-specific implants facilitate precise simulation and transfer of planned skeletal movements. However, accurate skeletal repositioning does not necessarily ensure soft-tissue harmony, and surgery may also affect adjacent anatomical and functional structures. Treatment should therefore combine precise skeletal repositioning with soft-tissue-oriented planning, careful TMJ and airway evaluation, and, when required, staged or adjunctive procedures to achieve stable, functional, patient-centred outcomes.

Tong Xi
One-stage surgery for facial asymmetry: How can we make it predictable?
-
Tong Xi
- Facial asymmetry should be approached as a 3D problem, not merely as a deviation of the chin or dental midline.
- Static and dynamic analysis of the growth and residual morphological anomalies are required to identify which corrections should be corrected.
- Combining orthognathic surgery with simultaneous condylectomy and angle ostectomies can address both condylar hyperactivity and residual skeletal asymmetry in a single procedure.
- Patient-specific planning and intraoperative transfer facilitate the translation of the virtual plan into a predictable surgical outcome.
- The goal is not to obtain perfect mathematical symmetry on X-rays but a balanced and natural facial appearance with a stable functional outcome.

Aranzazu Senosiain
Orthodontic keys to the decompensation of asymmetries
-
Aranzazu SenosiainOrthodontist, Madrid, Spain
Successful orthognathic correction of dentofacial asymmetries requires accurate diagnosis and effective presurgical orthodontic decompensation. Particular attention will be given to transverse discrepancies, dental midlines, occlusal cant, arch coordination, and asymmetric tooth positioning. Clinical strategies will be presented to optimize orthodontic preparation while avoiding movements that could compromise surgical planning or postoperative stability.
A coordinated orthodontic-surgical approach will enable more predictable functional, occlusal, and aesthetic outcomes.

Simon Littlewood
Aligners and clear plastic retainers for orthognathic patients: The future or a danger to our patients
-
Simon LittlewoodOrthodontist, Bradford, UK
- Aligners can now be used successfully in many orthognathic cases
- Aligners offer potential advantages for patients (aesthetics, hygiene) and for clinicians (less office visits, reduced chair time)
- Post-treatment results can be retained with clear plastic retainers, with the advantage of easier hygiene and allowing patients to take responsibility for long-term retainer wear
- However, as concerns are raised about the negative health impact of plastics on various organs in the body, are our plastic appliances a risk to health?
- This lecture will discuss the best current evidence on the potential dangers of microplastics and nanoplastics when using aligners and clear plastic retainers

Facial sculpting with patient specific implants
-
Johan Jansma -
Rutger Schepers
- Patient-Specific Implants (PSIs) can contribute to orthofacial surgery by enhancing facial symmetry and contour
- Sometimes a 3D-printed patient-specific chin implant may provide a better aesthetic outcome than a genioplasty
- Patient participation and careful planning in the 3D design phase are crucial for a successful outcome
- Statistical shape modelling can be very helpful to support implant design
- Pearls and pitfalls of facial sculpting with PSIs will be discussed

Raquel Guijarro Martinez
Redefining the jaw-neck interface in the era of orthofacial surgery
-
Raquel Guijarro MartinezOral and Maxillofacial Surgeon, Valencia, Spain
- The orthognathic surgery patient prototype has evolved substantially: While correcting a dysfunctional occlusion used to be the key concern, the wish to optimize facial esthetics—in the context of a dysfunctional occlusion or not—has currently become the main motivation for treatment in many cases.
- The number of adult patients who wish to undergo orthognathic surgery is increasing steadily. The coexistence of natural cervicofacial aging changes in these patients is very common. These changes are not always managed effectively with skeletal repositioning alone.
- Many cervicofacial soft tissue aging changes can be treated concomitantly at the time of orthognathic surgery.
- As in facial plastic surgery, a well-defined, sculpted jawline is a key goal in orthognathic surgery.
- This lecture offers the speaker’s approach for combined skeletal repositioning and jawline rejuvenation. Clear guidelines for patient selection and technical pearls for enhanced facial results will be given.

- Genioplasty performed with PSOs is highly accurate
- Our workflow will be presented, along with our scientific data to support our findings

The Bram Tuinzing Invitational Lecture by Emma Wooley
Are you a good doctor?
-
Emma Wooley
What does it mean to be a “good doctor” in modern healthcare and orthognathic practice? This presentation will explore the concept of goodness in medicine from multiple perspectives, examining how doctors/orthodontists, patients and society define and recognise professional excellence.
Drawing on evidence from medical education, professionalism literature and contemporary practice, the session will consider how values, behaviours and professional identity are developed throughout a doctor's career, and how we teach and assess what it means to be a good doctor. The presentation will also explore the growing influence of social media and the emergence of publicly accessible online profiles in shaping professional reputation and public trust.
Looking ahead, the session will examine how advances in artificial intelligence, digital technologies and robotics may redefine expectations of the future orthognathic clinician. As healthcare evolves, what uniquely human qualities will remain essential, and how should we prepare the next generation of clinicians?
The presentation will invite surgeons and orthodontists to reflect on their own professional practice and consider the enduring and emerging characteristics of a good doctor in the twenty-first century.

Raquel Guijarro Martinez
The restorative dimension of orthognathic surgery: Integrating the prosthodontist into the orthodontic-surgical team
-
Raquel Guijarro MartinezOral and Maxillofacial Surgeon, Valencia, Spain
- A holistic approach to orthognathic surgery involves a paradigm shift where the focus moves from “just” a functional occlusion to the comprehensive restoration of facial esthetics, occlusal health, airway function, and full dental rehabilitation. This treatment concept entails the incorporation of more disciplines into the conventional Orthodontics-Surgery dyad.
- Many orthognathic surgery patients have a worn dentition, missing teeth and/or altered vertical dimensions that cannot be resolved by bone movement alone.
- On the other hand, conventional full pre-surgical orthodontic decompensation is not always necessary to plan the skeletal movements. However, an unstable occlusion may hinder postoperative bone healing. In these cases, targeted dental restoration may bridge the transition phase and allow for a surgery-early approach.
- This presentation will share practical workflows for everyday scenarios where Restorative Dentistry can close the gap between skeletal correction and comprehensive full-face rehabilitation. These integrated protocols aim to optimize results while significantly reducing overall treatment times.

Enhanced recovery after surgery, approach for orthognathic surgery. A perioperative evaluation
-
Hakan Tuz
Enhanced Recovery After Surgery (ERAS) pathways are multimodal, evidence-based strategies designed to optimise perioperative care by minimising surgical stress, standardising clinical practice, and promoting a faster and safer recovery. Although these protocols have been successfully integrated into many surgical specialties, evidence supporting their application in orthognathic surgery remains relatively limited. This presentation will explore the association between the implementation of a structured ERAS protocol and key perioperative outcomes in patients undergoing orthognathic procedures, with particular emphasis on postoperative recovery, complications, length of hospital stay, and overall patient experience.
