The Preci-Vertix Hood is a prefabricated metal receptacle to receive and hold the Preci-Vertix Female (a Hader Clip). The use of the Preci-Vertix Hood eliminates the difficulties of duplicating and casting the female receptacle in the cast frame work. The Preci-Vertix Hood may be connected to the cast frame with self curing resin, by casting the frame against the Hood, or by soldering or welding.
Improves accuracy, reduces labor and saves time with multiple techniques.
Space may be critical. The Preci-Vertix Hood is best utilized in the bicuspid areas. See the Vertix Castable Hood for limited space applications.
Technique
The Preci-Vertix Male is cast with the retaining abutment patterns in the normal technique. Porcelain application is completed. To view these steps, click here.

| 3. Wax the frame up
to the area of the Hood. Struts may be waxed on each side of the tail
as the Hood (FIG 3). Complete
and finish the casting.
4. Reassemble the Hoods and cast frame on the master cast. Cut retention grooves in the tail of the Hood with a thin disk. Connect the Hood to the cast frame with self curing resin or by soldering (FIG 4). |
