In past years I was fortunate enough to attend courses with Dr. Robert Ricketts and his bioprogressive philosophy, considered by many to be one of the pillars of Modern Orthodontics.
He was essentially a researcher and statistician who revolutionized the techniques and diagnostic system in today’s Orthodontics. Ricketts learned Orthodontics practically “from those who invented it.” He had as teachers founding figures of Orthodontics such as Stainer, Nance, Brody, Tweed, who taught him their once famous cephalometry. Shortly thereafter, Ricketts verified with scientific methods that some bases of their cephalometries were “poorly referenced” because the cranial metric points that they considered “immovable” had many variations with growth. growth that can be perfectly predicted in healthy patients.
One of the most well-known and popular aspects of bioprogressive therapy has been its great, though irregular, diffusion throughout the world, in Spain and France, has had and It has a great reputation, as it does in many Latin American countries. The great strength of bioprogressive therapy is the early treatments in mixed dentition.
In this aspect, the identification of a growth pattern can predict and treat dental and/or skeletal alterations that will consolidate in adolescence.
Following the career of some contemporary leaders such as Dr D. Roth , Hugo Trevisi (MBT) , low friction brace and orthodontic and invisible aligners
their objetives are indicated for permanent dentition and little or nothing is said about early treatments in mixed dentition. That is why the author’s motivation is to include all the new technology in orthodontics with the bioprogressive philosophy.

Dr. David Sotomayor obtained his dental degree from the Metropolitan University of Barranquilla, Colombia (Unimetro), in 1997. He then attended John F. Kennedy University in Buenos Aires (BA), Argentina (Kennedy U.), where he completed his orthodontic training and received his specialist degree in orthodontics in 2004. After completing his thesis work related to facial biotypologies, Dr. Sotomayor was proud to have received a direct invitation from the academic committee to join the faculty at Kennedy U, working uninterruptedly in the area of cephalometric diagnosis and Ricketts bioprogressive clinic for 13 years. Wanting to improve the success rate of his orthodontic treatments, in 2006 he completed a postgraduate degree in minor implant surgery at the Argentine Circle of Dentistry (CAO). Introducing the new, currently available, TADs temporary anchorage screws. This allowed him to teach theoretical and practical courses both at his alma mater and at various institutes in Buenos Aires.
Finally, between 2011 and 2013, he studied medicine at the Universidad Abierta Interamericana (UAI) with the goal of furthering his surgical training. Beyond not pursuing a medical career, those two years allowed him to improve his understanding of the human body more comprehensively, understanding and confirming that our patients are not just a bunch of crooked teeth but rather physiologically connected systems.
