Biomedicine- and Technology-driven Paradigm Shifts in Orthodontics - Jacob A. Salzmann Lecture
Groundbreaking advances in 3D imaging, computer technologies and biomedicine that have transformed medicine are being rapidly adapted and applied to orthodontics. Dr. Kapila will discuss the integration of these advances into orthodontics with an emphasis on 3D imaging, smart appliances, tissue engineering and biologic regulation of tooth movement and facial growth. He will also highlight the implications of these innovations to the future practice of orthodontics.
Learning Objectives:
Over the last 2 decades skeletal anchorage has widened the scope of moving teeth. Because of the limited surgery, miniscrews became very popular. However, inserted at the labial site, they limit the movement of adjacent teeth, and in the palate they are commonly used as indirect anchorage. More recently they are also used for bone supported rapid maxillary expansion.
Miniplates resist higher forces and are labially inserted at a distance from the teeth. That makes them more suitable for class II orthodontics, class III orthopedics, and complicated orthodontics in combination with orthognathic surgery.
An update will be given on our latest insights in biomechanics, treatment outcome, and some new perspectives for the future.
Learning Objectives:
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.

In this presentation, Dr. O'Brien will discuss the dilemma of attempting to practice evidence-based orthodontics. He will use examples from his own work based on clinical trials on how research reduces, or increases, clinical uncertainty. Finally, he will discuss the effects of social media, anecdote, key opinion leaders and snake oil salesmen on counteracting the effects of orthodontic research and increasing uncertainty about our treatment.

In 1974, Jacob A. Salzmann published a book entitled, Orthodontics in Daily Practice. That same year, my dad returned from hospital rounds and out-of-the-blue suggested that I should be an orthodontist. A decade later began my reality of “weird tales about teeth” in daily practice. From addressing a collection of controversies to developing concepts and devices to improve the predictability of clinical practice, seems that I have thrown everything at them, except the kitchen sink (but on second blush . . .). Along the way, it has been a journey of accidents and epiphanies. Providing more than just lip service for esthetics, pulsus a mortuus equus on extractions, and suggesting conservative early treatment, these topics have occasionally been presented in what Edward Angle described as “an attitude of friendly hostility.” From uno, dos, tres miniscrew innovations to improvements in drastic plastic, combined with research on “scar tactics,” offering canine obedience training, and a simple quick fix, this road has proven that an avid approach to a vocation might also transform into a passionate avocation, much as it was during Jacob Salzmann’s career.
