The invention can be used during dental occlusion operations, for example. ## Claims ### Claim 1 Customized assembly (1) of at least two osteosynthesis plates (2), characterized in that the osteosynthesis plates (2) are connected together by a rod (3), said rod further comprising two protrusions (4) protruding from said rod (3) at a position spaced away from said plates (2) and configured to protrude towards a nasal orifice (8) of a patient into positions that correspond to the two ends (5, 6) of a base (7) of the nasal orifice (8) of the patient; wherein each osteosynthesis plate comprises a first portion configured to be fixed to a first bone part of a jaw and a second portion configured to be fixed to a second bone part of the jaw, said osteosynthesis plates being for use in orientating the second bone part in relation to the first bone part, and wherein said rod is coupled between the first portion and the second portion of each osteosynthesis plate. ### Claim 2 (depends on 1) Customized assembly (1) of at least two osteosynthesis plates (2) according to claim 1, characterized in that the two protrusions (4) are made in the shape of studs or of fingers or of lugs or of spurs configured to protrude directly from said rod (3). ### Claim 3 (depends on 1, 2) Customized assembly (1) of at least two osteosynthesis plates (2) according to any of the claims 1 and 2, characterized in that the rod (3) of said assembly is configured to perfectly follow the anatomy of the patient. ### Claim 4 (depends on 1, 2) Customized assembly (1) of at least two osteosynthesis plates (2) according to claim 1 or 2, characterized in that close to each of its plates (2), the rod (3) of said assembly has zones of reduced resistance (11) designed to make it easier for the surgeon to cut all the connecting parts between the different osteosynthesis plates of said assembly. ### Claim 5 (depends on 1, 2) Customized assembly (1) of at least two osteosynthesis plates (2) according to claim 1 or 2, characterized in that it is made of a single piece. ### Claim 6 (depends on 1, 2) Customized assembly (1) of at least two osteosynthesis plates (2) according to claim 1 or 2, characterized in that it is made of titanium. ### Claim 7 Method for implanting at least two osteosynthesis plates (2) on the maxillary (10) and/or mandible of a patient during a dental occlusion operation, characterized in that, as preliminary to said operation, the results of the operation on the patient are simulated in advance, the position and shape of the osteosynthesis plates (2) are determined according to the future anatomy of the patient, an assembly (1) of at least two osteosynthesis plates is custom made, which are themselves customized according to the operation to be carried out and the future anatomy of the patient, said assembly (1) comprising a rod (3) that connects together the osteosynthesis plates (2) and that further comprises two protrusions (4) protruding from said rod (3) at a position spaced away from said plates (2) and corresponding to the lower comers (5, 6) of the patient's nasal orifice (8) and in that the surgeon implants said customized assembly (1) by placing its two protrusions (4) in the lower comers (5, 6) of the patient's nasal orifice (8), then fastens all the osteosynthesis plates (2) by means of screws penetrating the bone elements of the upper jaw or of the lower jaw in question, then cuts close to each of the osteosynthesis plates (2) of said assembly all the connecting parts formed by the rod (3) between said plates (2). ### Claim 8 (depends on 7) Method according to claim 7, characterized in that the surgeon cuts all the connecting parts between the osteosynthesis plates (2) formed by the rod (3) of the customized assembly (1) by using to this effect zones of reduced resistance (11) provided close to each of said plates. ### Claim 9 (depends on 1, 2) Customized assembly (1) of at least two osteosynthesis plates (2) according to claim 1 or 2, characterized in that the osteosynthesis plates (2) are L-shaped. ### Claim 10 A customized assembly made of a single titanium piece, said assembly comprising: at least two L-shaped osteosynthesis plates (2) including through holes (9) configured to receive screws to fasten the assembly into bone parts; and a rod (3) connecting the osteosynthesis plates (2), said rod (2) comprising zones of reduced resistance (11) in the vicinity of each of the different plates (2) being designed to cut all the connecting parts between each of the different osteosynthesis plates, said rod further comprising two protrusions (4) spaced at a position away from said plates (2), characterized in that the two protrusions (4) are made in the shape of studs or of fingers or of lugs or of spurs, and configured to protrude directly from said rod (3) towards a nasal orifice (8) of a patient into positions that correspond to two ends (5, 6) of a base (7) of the nasal orifice (8) of the patient; wherein each osteosynthesis plate comprises a first portion configured to be fixed to a first bone part of a jaw and a second portion configured to be fixed to a second bone part of the jaw, said osteosynthesis plates being for use in orientating the second bone part in relation to the first bone part, and wherein said rod is coupled between the first portion and the second portion of each osteosynthesis plate.
