3. Educational goals

4. Impression making in implant
understand the importance
Name the goals
Recognize the difference between implant impressing with natural teeth
List the different technique
Identify the impression component
comprehend the differences of technique
Count the indication of each technique
make use of the methods

5. Passive fit frame work and no stress applied to the fixture from superstructure
Accurately relate the hex position of fixture/abutment to the other structures in the dental arch
Goal of impression

6. Implant/teeth impression
Natural teeth
implant
Hand made preparation
Transfer of surface detail
Transfer the position of teeth
Retraction of gingiva is possible
Precise machine part
Only need to transfer the hex situation

7. Impression Technique in implant
Fixture level impression technique
Indirect (CLOSE TRAY) or (TRANSFER)
Direct ( OPEN TRAY) or (PICK UP)
Splinted
Non splinted
Indexing
Abutment level impression technique
Without modification
Direct
Indirect
With modification

8. COMPONENET FOR IMPRESSION IMPRESSION COPING/ ANALOUGE

9. Pick up / transfer technique
Direct
Indirect

10. indirect technique

12. DIRECT technique / splinted

13. Direct technique/ Splinted

15. Pick up technique/ NON Splinted

16. Pick up technique/ Non Splinted

17. PICK UP versus TRANSFER Accuracy
There is no universal answer have been found
For 3 or fewer implant no difference is shown between the technique
In deep sub gingival situation the extension of impression coping had effect in accuracy

Customized healing cap / immediate loading/
Indexing in dental implant

19. Indexing Technique

20. TIP Insure seating of the impression coping
Tactile sense
Radiograph
Notice to the requirement of material of choice (poly ether, PVS,…)
Errors are more obvious in implant (precise machine fit of component)

21. Impression material selection
Silicone
Polyether
In pickup technique :
More rigid material
In transfer technique:
Elastic material with good recovery

22. Abutment level impression
Without modification of abutment
(SCREW TYPE RESTORATION)
Direct ( Pick up)
Splinted
Non splinted
Indirect( Transfer)
(CEMENT TYPE RESTORATION)
With modification of abutment
