Preci Post System

Benefits:

Great communication tool between the Dentist and the Laboratory
Provides for consistent and accurate castings
Inexpensive and easy to use
Impression posts have a "head" for retention in any impression material, and will bend with out breaking or distorting. Impression posts are self-separating and will not adhere to most die materials, so a model may be poured up with out distortion
The burn out posts compensate for expansion/contraction of investing/casting and burn out cleanly with any alloy--including non-precious

Preci Post Instructions

1	2
1. Prepare the root canal with either the Yellow or Blue Root Canal Reamer (FIG 2). Roughen the posts to provide retention (FIG 2).
3	4
2. Place the corresponding yellow or blue opaque impression post in the canal (FIG 3). 3. Take an accurate impression. The posts are provided with retentions for a proper fit in the impression material and will allow it to be draw off with the impression (FIG 4-5).
5	6
4. Pour the master model and prepare dies. The Impression post is self-separating and will not adhere to most die materials (FIG 6).
7	8
5. In the Laboratory, remove the impression post and replace it with the transparent laboratory burn-out post (FIG 7). Reduce it to its correct length and make sure that the top offers a little retention for wax. 6. Make the wax pattern directly to the post (FIG 8).
9	10
7. Sprue, invest (Preci-Roto System), burnout, and cast the pattern (FIG 9). The result is always an exact fitting post-coping without solder joint (FIG 10).
