The most important objective of this article is to contribute for a psychosocial approach in therapeutic network, recommended for community services, in the context of the psychiatric Brazilian reform. The entrance door of those services in the SUS (Unified Health System) would be a Community Mental Health Center (CAPS) for this specialty and a PSF (Health Family Program) for a generalist health approach. The therapeutic network in the first micro-organization would function into an institutional system articulated and in solidarity with health organizations and also inserted in public policies programs that intend not to abandon the patient. The focus in this study is a process of deconstruction of the total institutions in mental health that forms a traditional circuit centered in the psychiatric hospital and a construction of a new mental health system that could function according to an autopoietic institutional dynamics. This situation could facilitated dialogical mediations in therapeutic relations and between the interventions connected with other institutions and could contribute for the social insertion of the user. Consequently, the psychotherapy practiced at the CAPS could include the possibilities of setting variations and network interventions in the significant social network of the patient, if necessary. It is concluded that there would be, in many cases, a dichotomy between this theorization and the practice in mental health in the SUS. It is recommended that the necessary steps should be taken in professional practices and public policies programs in order to overcome this dichotomy and qualify the mental health interventions.
