Splints for injected veneers

Splints for injected veneers, which are designed based on computer-assisted planning and performed by injection using 3D printing by extending successive layers of additive material that adapts to teeth of a patient already prepared or conditioned, said splints to be used as transfer tools for a fluid composite resin that is injected through holes (6) and subsequently photocured in the mouth over the teeth to shape a veneer thereover, comprising:

• two different splints made for each patient and arch comprising:
• a first splint (1) internally exhibiting a mold with at least a desired configuration of alternate teeth (D1, D3, D5, etc.), while on remaining teeth (D2, D4, D6, etc.) that are not going to be repaired with this first splint (1) in a first phase, the first splint defining a series of outwardly-bulging windows (4) that internally form air retaining spaces, which will allow air contained in said outwardly bulging windows to break a void created between the first splint and the remaining teeth in order to allow the first splint (1) to be easily detached and removed once the fluid composite resin applied to the alternate teeth (D1, D3, D5, etc.) has been injected and dried;
• and
• a second splint (2) internally exhibiting a mold with a final configuration of all the teeth including the alternate teeth which were repaired (D1, D3, D5, etc.) and protected by the second splint (2) due to the flexibility of the mold of the second splint, and the remaining teeth (D2, D4, D6, etc.), alternated between those teeth which were repaired in the first phase, are repaired by injecting fluid resin into the mold of the second splint (2), which also defines a series of outwardly-bulging windows (4) that define a cavity for air between the second splint and the remaining teeth in order to allow the second splint (2) to be easily detached and removed once the fluid composite resin applied to the remaining teeth (D2, D4, D6, etc.) has been injected and dried.
