The literature and experience of working in primary health care allowed the author to reflect on the main features of the matricial practices of health care networks in the context of the SUS over the years. Matricial practice current notion seems to put forward consulting practices and supervision by teams or professionals to whom the quality of experts is assigned. The effects of this relationship between teams and services are discussed and the benefits in the context of management and health care are analyzed. Sustained in the original proposal of matricial practice, the article establishes a problematization that derives logical consequences to build a notion that is different from that sustained the barren relationship between specialists and generalists. With the support of the mathematical theory of matrix calculus, it builds the concept of matricial practice that could contribute to implement collaborative relationships between teams and services with important and resolving effects in the field of care and management of comprehensive health care.
