Unipost Prosthetic Procedures

1. During the implant surgery appointment select the correct post guide of either 0, 10, 20, or 30 degrees and record the information in the patient’s chart. This offers two advantages.

A - Pre-selection of the post is an effective inventory control procedure to insure the required post is available at the prosthetic appointment. (If the angle exceeds 30 degrees, custom posts of 40, 50 and 60 degrees are available on special order.

2. Evaluate the healed implant. The usual healing time is 4 months in the mandible and 6 months in the maxillae prior to “safe” prosthetic loading.

A - View radiograph or digitized tomography for bone healing.

B - Evaluate soft tissue surrounding the implant for inflammation and home care.

C - Percussion test – Tap the implant with the end of a mirror handle. A well integrated implant will generate a distinctive ringing – solid sound.

3. Clean and polish the implant with chlorhexadine and soft abrasive.

4. Remove the left hand threaded healing screw. Place protective gauze in the posterior to prevent aspiration when placing or removing component parts in implants.

5. Rinse the internal of the implant with water. Acid etch the internal of the implant with 37% phosphoric acid.

A - Use try-in post guides to confirm or select the correct angle for the prosthetic posts. Repeat the preceding steps if multiple implants are involved.

B - Try-in the selected post to evaluate vertical height and paralleling alignment. The post must rotate freely without resistance.

6. If the post threads were tight and resistance was encountered when trying the post in, air-abrade the threads on the post with aluminum oxide to reduce the profile of the thread. This will allow free rotation of the post during cementation.

7. Mark or index the post for gross reduction outside the mouth.

8. Screw the post in a post holder handle for convenient gross reduction of the post. This may be done chair-side or in an in-office laboratory.

9. Test the modified post for accuracy of the gross reduction. Make any other modifications required prior to post cementation.

10. Retest the anticipated final position of the cemented post.

11. Index the implant to post relationship for final cementation.

12. Verify that the internal of the implant is clean and dry. Re-etch if necessary.

13. Lightly air-abrade with aluminum oxide the threaded area of the post to be cemented.

14. Etch the threaded area of the post. Wash and dry. Rinse and dry the internal vent with forced clean air.

15. Cement with Panavia or Resiment by carrying a small amount of cementing agent to the interior of the implant.

16. Carefully rotate the threaded post into place. Align the post on the rotational axis at the predetermined position.

17. Check for extrusion of the cement through the vent in the post.

18. Allow adequate time for cementing agent to completely set.

19. Perfect preparations with paralleling design. Create proper gingival margins and place an anti-rotational groove on the body of the implant.

20. Take a final impression with crown and bridge impression material. Hydrocolloid impression material works extremely well with narrow diameter implant posts.

21. Complete the necessary laboratory steps in a normal crown and bridge manner.
