The TOI (Ideal Dental Treatment) philosophy proposes a comprehensive and humanized approach to dentistry, combating disciplinary fragmentation by focusing on prevention, function, and aesthetics simultaneously. It is structured in a four-level methodological pyramid—diagnosis, planning, clinical execution, and control—which must be followed sequentially and in an interconnected manner. The primary goal is to bring the patient to the highest level of oral health, considering the individual holistically. More than a protocol, TOI is a philosophy of professional practice and training that seeks to transform dental practice and the awareness of professionals. A project in the city of Avaí (SP) exemplifies the practical application of this philosophy on a community scale, aiming at long-term results in the oral health of the population.
