The bienniel international prize is awarded for the best scientific contribution to clinical orthodontics over the past two years and consists of a cash prize of € 2,500. Orthodontists Prof Dr Christina Erbe, Dr Edwin Ongkosuwito, and Dr Nop Willems formed the Begg Prize jury. Winner of the previous Begg Prize was orthodontist Dr Aldin Kapetanović for his PhD research into the effects of Miniscrew-Assisted Rapid Palatal Expansion (MARPE) conducted at Radboud University Nijmegen, the Netherlands.

Winner of the Begg Prize 2026 was orthodontist Sebastiaan P Van Doornik for his PhD research into the implementation of a clinical guideline on External Apical Root Resorption (EARR) conducted at the University of Groningen, the Netherlands. The dissertation’s promotors are Prof Dr Yijin Ren, Prof Dr Anne Marie Kuijpers-Jagtman, and Prof Dr David Manton. Mr Van Doornik hopes to defend his PhD research at the University of Groningen on September 16, and the prize will undoubtedly be an extra motivation for him. The full title of Mr Van Doornik’s dissertation is: Patient-centred, evidence-based orthodontics. Managing white spot lesions and root resorption through patient behaviour, interventions, and clinical guidelines.

According to the jury report, the results of Mr Van Doornik’s research are of great clinical importance, because EARR is a complication that remains highly relevant in everyday orthodontic practice and has the potential to affect any patient undergoing orthodontic treatment.
