Anthogyr pivot master Notice D'instruction page 17

If necessary, create a base for the head using a countersink matching the
diameter of MD to be fitted (same colour code as the drill/reamer or the
MD).
vII.4 – case of posts
1. Check the physical entirety of the post (manufacturing defects, signs of
impact, corrosion ...) before fitting it in the mouth.
2. Fit the dam in the mouth.
3. Insert the selected metal post into the hole made. Do not use castable
posts to make impressions. There is a difference (2/100) between metal
posts and castable posts; castable posts are not as thick, leaving space
for the sealing cement, thus avoiding too much friction between the metal
and the tooth.
4. Make the impression.
5. Send the impression to the laboratory with the metal post still inside,
together with the associated castable post (same colour code). In the event
of divergent roots, include the corresponding lock(s) (stainless steel and
castable).
6. The temporary crown is created by inserting a metal post, identical to the
one used for the impression, in the canal. Only place the temporary cement
on the edges of the crown and not on the post.
7. In the laboratory: Cast the master model, insert the castable post in
the master model and make the model. It is cast using the conventional
method.
8. In the dental office: Try on the prosthesis and seal permanently.
vII.5 – case of screw-posts and posts
1. Check the physical entirety of the post or the screw-post (manufacturing
defects, signs of impact, corrosion ...) before fitting in the mouth.
2. Fit the dam in the mouth.
3. Apply the sealing cement using a paste-filler (lentulo).
4. For screw-posts: use a key to fix the MD in place inside the canal. Use a
hollow key or, if there is not enough space, a cruciform key. Use the hole in
the key and dental floss to make a safeguard system so that the MD cannot
get lost inside the mouth.
