The rivalry between Edward Angle and Calvin Case is a notable example of how power dynamics within a discipline can shape what is considered valid knowledge. Edward Angle, known as the "father of modern orthodontics," championed the idea that all permanent teeth should be preserved in orthodontic treatments. He developed the first classification system for malocclusions, which remains influential today, and founded the first formal school of orthodontics, giving him significant power and influence in the field.
Calvin Case, a contemporary of Angle, presented a different theory. He believed that selective extraction of teeth could be beneficial in cases of severe crowding and to improve facial aesthetics. However, this idea clashed with Angle’s vision, who was a staunch opponent of extractions. As Angle wielded significant institutional power, he used his influence to promote his own approach while marginalizing Case’s ideas.
Foucault’s Theory of Power and Knowledge
This historical conflict can be better understood through the lens of Michel Foucault's theory on power and knowledge. Foucault argued that knowledge is not neutral or independent, but rather deeply intertwined with power structures. Those who hold power in society also control what is considered "truth" or "valid" knowledge. In this case, Angle, with his institutional power, was able to dominate the orthodontic discourse, pushing Case’s ideas to the margins.
Foucault also highlighted the concept of discourse control, meaning that power is exercised not only by coercion but by determining who can speak, what can be said, and what must remain silent. Angle's position allowed him to shape the discourse within orthodontics, defining the preservation of teeth as the accepted norm and casting Case’s theory of extractions as unorthodox. The exclusion of Case from key orthodontic societies like the American Society of Orthodontics illustrates how power can silence alternative voices, influencing the development of knowledge within a field.
The Tragic End of Calvin Case
As a result of the intense professional pressure and exclusion from key orthodontic institutions, Calvin Case’s career declined. The constant rejection and inability to have his ideas accepted within the field led him into deep depression. Tragically, in 1923, Case took his own life. While the specific details of his suicide are not widely documented, it is widely believed that his professional isolation and the failure to gain institutional recognition contributed significantly to his despair.
The tragedy of Case’s suicide underscores how power dynamics within a professional field can have not only professional but also personal and psychological consequences. His exclusion from the dominant discourse in orthodontics became not just a professional defeat but a deeply personal one, illustrating the toll that marginalization can have on individuals.
Legacy and the Return of Case's Ideas
Despite Case's tragic end, his ideas about extractions were eventually revisited and accepted in modern orthodontics. Decades later, the orthodontic community began to recognize the value of selective extractions in certain cases. Ironically, the very ideas that were dismissed during Case’s time became part of standard orthodontic practice, showing how knowledge evolves as power structures shift.
From a Foucauldian perspective, this demonstrates how power not only produces knowledge but also regulates it. Theories that were once marginalized can become accepted once the power dynamics change. However, for individuals like Case, who found themselves on the wrong side of power, the cost of challenging the status quo can be devastating.
Conclusion
The story of Angle and Case is a clear example of how power can influence the creation and validation of knowledge. Foucault argued that truth is not static or absolute, but is shaped by those who control the institutions that produce and regulate knowledge. In the case of early 20th-century orthodontics, Angle’s power shaped the evolution of the field, while Case’s theory was sidelined until much later.
This history also highlights the human cost of power struggles within any professional field. Case’s exclusion and eventual suicide remind us that the battle for recognition and validation can have profound psychological consequences, particularly when power dictates who gets to define the truth.
