Abstract The golden hour in trauma care.

Dr. G. Giannakópoulos
The principles of the Golden Hour in treatment of Trauma with focus on Facial Trauma.

Abstract The trauma of the teeth; the differences between the dental practice and the hospital.

Drs. M. Soffner, Endodontist ACTA and Prof. dr. L. Dubois, Oral and maxillofacial surgeon, AmsterdamUMC.
Dentistry, in general, is a profession that can be reasonably planned. However, there are also circumstances within dentistry where the need for acute intervention is high. A good example is dentoalveolar trauma. In avulsed teeth, time is a crucial factor for success. In the hospital setting, patients are often more seriously injured, which affects treatment choices. Unfortunately, this results in a different perspective on trauma care in the hospital compared to the dental practice. This lecture discusses the basic principles of dentoalveolar trauma. The differences between the dental practice and the hospital are highlighted. This lecture shows that the organisation of the whole chain of emergency dental care can play a vital role in optimising clinical outcomes.

Abstract Trauma around the teeth.

Prof. dr. J. de Lange, Oral and maxillofacial surgeon, AmsterdamUMC.
Diagnostics and Methods of Operative stable fixation of Maxillo-& Mandibular Fractures.

Abstract Complex facial injuries: bringing the pieces together.

Dr. R. Helmers, Oral and maxillofacial surgeon, AmsterdamUMC.
This lecture will give you an insight in complex facial injuries. Bringing the pieces together when most reference is lost. The difficulties that arise during the diagnostics and treatment of extensive panfacial injuries will be discussed. How to manage the airway during operation and postoperatively? How to restore the normal facial proportions in all dimensions? Which combination of fracture types complicate adequate treatment of midface fractures and what are the clinical consequences? What are the special considerations involved in treating edentulous mandibular fractures? These topics will be addressed and illustrated with trauma cases that were treated in our department.

Abstract Functional and dental rehabilitation after facial trauma.

Dr. J. Liebregts, Oral and maxillofacial surgeon, RadboudUMC.
By using image fusion, image data of cone-beam computed tomography, intra-oral scan and 3D stereophotogrammetry can be rendered to create a 3D virtual augmented head model. In this way, the malposition, deficiency and other anomalies of the facial soft tissue, facial skeleton and dentition can be quantified in an objective way. Based on the principle of backward planning, the jaw movements, the location and number of dental implants and the need for bone augmentation that are required to obtain the desired treatment outcome can be determined with a high predictability. The implementation of 3D planning in the routine clinical workflow of complex multidisciplinary treatment has enhanced the efficacy of the health care pathway and has fuelled further innovations in oral and maxillofacial surgery. Several case studies illustrate how 3D simulation can help with complex orofacial problems.

Abstract The impact of advanced technology on clinical outcomes in facial trauma.

Dr. R. Schreurs, Technical Physician and Prof. dr. L. Dubois.
Facial trauma can have a significant impact on daily life. Aesthetic and functional complaints, or a combination, may occur after facial trauma, warranting surgical reconstruction. Ideally, the reconstruction outcome would mimic the pretraumatic situation as closely as possible. Although the maxillofacial surgeon is trained to restore aesthetics and recover function, this can be highly challenging.
Luckily, advanced technologies are helping to improve the predictability of reconstructions. This lecture discusses the fundamental principles of computer-assisted surgery in facial trauma. Advanced technologies such as surgical navigation or 3D printing have become the standard of care over the last few years, and improvements to the workflow through artificial intelligence, augmented reality, or robotic surgery may follow in the future. Further personalisation of the treatment is possible if reconstruction is performed with a patient-specific implant. The central topic in this dual lecture is to demonstrate the impact of technology and how this improved the clinical outcome in facial trauma care, with a peek into exciting future developments.

Abstract Dental and clinical aspects of Fibrodysplasia Ossificans Progressiva (FOP).

Drs. E.C.M. Bouvy-Berends, D.D.S. Special care Dentistry.
Fibrodysplasia ossificans progressiva (FOP) is a rare, disabling genetic disorder characterized by congenital deformities of the big toes and progressive heterotopic ossification (HO) of connective tissue in specific anatomical patterns. FOP is the most catastrophic state of HO in humans. Inflammatory episodes (flare-up) eventually lead to ankylosis of all major skeletal joints, leading to cumulative immobility. Although drug research has increased, there is still no drug to reduce or prevent HO.
Limitation of jaw movements and mouth opening due to HO in the maxillofacial region is observed in approximately 70% of FOP patients by the age of 19 years. The results of a recent study of causes and locations of heterotopic ossification in the maxillofacial region are discussed followed by oral care recommendations for FOP patients.

Abstract Noma, a neglected disease of the poor.

Dr. J.J. de Mol van Otterloo, Oral and maxillofacial surgeon, Kennemerland NL.
Since the Ancient Ages, Noma has been described as an infectious disease in childhood, starting as an ulcerative gingivitis, in relation with poor nourishment, poor oral hygiene and a decreased immune system. In a world with an increasing poverty in so many countries and the knowledge of the past it is important to be aware of the circumstances in which Noma has the biggest chance to get a full development. Treatment of Noma is challenging and difficult.
