1. APPLICATION OF ABUTMENTS IN IMPLANTOLOGY
DR. KAMAL SHIGLI

3. DEFINITION The abutment is the portion of the implant that supports and/or retains a prosthesis or implant superstructure.

4. ABUTMENT COMPONENTS
Abutment Cylinder
Abutment Screw
“O”- Ring

5. CATEGORIES OF IMPLANT ABUTMENT
Abutment for screw retention
Abutment for cement retention
Abutment for attachment
One piece/Two piece abutment
Abutment types may also be classified as:
Straight or Angled abutments

6. ANGLED ABUTMENTS
Improve the path of insertion
Esthetics

7. ABUTMENT SELECTION CRITERIA
Orientation of Implant
Esthetic demand
Type of restoration

8. UCLA (University of California, Los Angeles)
It fits directly on top of either the implant fixtures intraorally or the laboratory implant fixture analogues,which are placed in the master cast.
It is a plastic castable sleeve which was made to simplify the complicated prosthetic rehabilitation.

9. INDICATIONS
Limited interocclusal distance
Esthetics

10. CERA ONE ABUTMENT
It was originally designed for anterior maxillary single-tooth cementable porcelain restorations.

11. UMA (Universally Modified Abutment)
Indications
Retrievable prosthesis
Overdenture bar construction

12. OVERDENTURE ABUTMENTS
The Overdenture abutment offers a simple solution for stabilizing an overdenture with implants.

13. OVERDENTURE ABUTMENTS

14. NEWER TRENDS…….. Procera abutment designed using the CADD technique.
an “abutment solution for every situation.”

15. NEWER TRENDS…….. Bicon abutment
Unlike other dental implants,it requires only two parts.
No screws,torque drivers,impression posts or special copings.
A locking taper joins the implant to the abutment.

16. NEWER TRENDS…….. CerAdapt abutment
Is an all-ceramic alternative to metal abutments.
Is a premachined, precision-milled abutment made to fit the implant hex.

17. CONCLUSION
The quest for an ideal prosthetic abutment/implant connection is still on….
