Preci-Sagix
Patented snap mechanism to provide patients with secure prosthesis retention!
|
|
The Preci-Sagix is ideal as an extracoronal attachment on extracoronal partial dentures as well as distal, lingual, or buccal placement on overdenture bar cases.
There are three choices of male:
*plastic castable pattern (any hard alloy can be used)
*cast-to noprax (for use with any dental alloy)
*threaded male and base ring (2.2mm size only) |
|
| |
|
|
Choose the Preci-Sagix male that fits the case best, either the 1.7mm mini or the 2.2mm standard.
When space allows, choose the 2.2mm ball.
The prefabricated NOPRAX cast-to male is recommended over the plastic castable male due to the accurate, machined precision fit of the ball. |
| |
After waxing the abutments/bar to full contour, use the #1300P Preci-Sagix paralleling mandrel in a surveyor to set the male attachment. A box can be created in the waxup to accomodate the proximal plate of the male attachment.
The flat proximal plate on the Sagix male may be reduced if needed, but this proximal plate will help provide prosthesis stability.
The male should be placed as close as possible to the tissue to reduce abutment stress, increase inteocclusal space, eliminate food traps, and allow for good esthetics and hygiene. |

Do not sandblast to devest or use rubber wheels to polish the attachment. Glass beads, shells, or a PREAT fiberglass pencil work when devesting to maintain the accuracy of the male attachment. Lightly polish to a smooth finish. |

Housing Cast with Framework: Place the pink processing female on the ball. Make sure the duplicating females are positioned parallel to each other and all undercuts are blocked out when duplicating and creating the refractory cast. |
|
|
|
|
| |
|
|
| The framework is design and waxed up on the refractory cast. A 180 degree lingual arm with deep rest is recommended. Take special care when designing the attachment housing over the duplicated pink female. Add retentions, invest, cast, and finish the framework. When finishing the framework, do not overpolish the inside of the female housing. |
|
|
|
| |
|
|
| |
| Using the prefabricated Metal Housing: Seat the pink processing female inside the housing on the cast. |
|
Block out all undercuts and duplicate. Design framework so that a) the housing tail is connected to framework or b) the framework is designed to leave sufficient room for incorporation of the housing into acrylic resin. |
| |
|
|
| |
|
|
| Use the Sagix #1323 insertion tool to place the pink processing female into the cast framework. After succesfull try in of the partial denture framework and tooth setup, process the partial denture with normal technique. An alternative technique with the prefabricated metal housing is to have this luted to the framework with self curing resin during try-in. |

|
|
|
| After processing, use the Sagix insertion tool to place the appropriate female insert--white (weak), yellow (standard), or red (strong) retention. |
