Comparison of Methods of Retaining Crowns on Implants

About this Seminar

Practitioners are constantly faced with how to best retain their implant restorations. This lecture will review the status quo on when one should consider cementing or screwing down a restoration to an implant. New ways, eliminating screws and cements, to retain restorations will also be introduced.

Objectives: Upon completion of this presentation, participants should be able to: 1) discuss the importance or retrievability with implant restorations; 2) triage placing cemented, screw or memory metal (Smileloc) retained restorations with single versus multiple implants; and 3) discuss the use of abutments with cemented, screw or memory metal (Smileloc) retained restorations.


1. Q: What are the various ways to retain restorations to implants?

A: Cement, screw, frictional retention, memory metal (Smileloc)

2. Q: What is the major advantage of using screw retained and memory metal (Smileloc) retained implant restorations?

A: Predictable retrievability

3. True or false. More biological complications are seen with screw retained implant restorations than with Screw or memory metal (Smileloc) retained restorations.

A: True

4. Q: How does the memory metal (Smileloc) coping retain implant restorations?

A: 8 nitinol memory metal flaps mechanically “lock” the restoration in place, 4 inner to the abutment and 4 outer to the coping.

5. Q: How does the memory metal (Smileloc) coping “unlock” the implant restorations?

A: An induction unit provides energy (heat) to unlock the (Smileloc) coping.
