An occlusal plate (10a, 10b, 10c), particularly for
dental treatments, comprising at least one first element (11a, 11b, 11c) designed to be worn on at least one
dental arch (1) of a patient. The at least one first element (11a, 11b, 11c) is shaped like a half-shell shape and has an
internal cavity (12a, 12b, 12c) which substantially reproduces, in negative form, the anatomical shape of the at least one
dental arch (1). The particularity of the occlusal plate (10a, 10b, 10c) resides in that the at least one first element (11a, 11b, 11c) has a contoured profile (13a, 13b, 13c) designed to make contact, at least partially, with the dental neck (14) of the teeth of the patient, and comprise sealing means (15a, 15b, 15c) adapted to provide, at least partially, a fluid-tight seal with the at least one
dental arch (1) and in that it comprises a base (21a, 21b, 21c) which comprises at least one first duct (22a, 22b, 22c) for the passage of a
working fluid for
dental treatments; the occlusal plate (10a, 10b, 10c) further comprises a plurality of second ducts (23a, 23b, 23c) which communicate with said first duct (22a, 22b, 22c) and lead onto an
occlusal surface (19a, 19b, 19c).
