Design and operation of splint activator - Made from flexible material as one single piece - Center is even and approximates the shape of an ideal dental arch - Surrounded by ramp-shaped walls - Teeth of upper and lower jaw bite into space between walls - No individual tooth slots, except in Australian Myobrace design

History of splint activator - In early 1950s, French orthodontists Prof. René Soulet and Prof. André Besombes used rubber retainers during summer holidays - Tooth and jaw anomalies improved during this time - Construction was improved and called Conformateur - Developed as a way to stabilize results achieved with fixed braces - Became a precursor to the splint activator
