Cement-Retained Restorations

A screw-retained abutment on which a crown or bridge-retainer unit is cemented.

Considerations

Benefits

  • In large-span bridgework using cast-metal frameworks, inaccuracies may arise due to casting distortion or post-ceramic firing distortion. Cement-retained restorations are more ‘forgiving’ in terms of fit and this compensates for some of the inaccuracies that may arise when casting.
  • The implant angulation and therefore screw access position is not critical as the abutment can ‘compensate’ for this.

Considerations

  • Depending on the nature of the luting cement, cement-retained restorations may either become loose unexpectedly or can be difficult to remove i.e. poor retrievability.
  • Excess cement may present a problem if not cleaned from around restoration margins especially if these are subgingival. Cement retention in the gingival sulcus may lead to peri-implant mucositis or potentially peri-implantitis.

SCD produce implant-retained restorations with either original or genuine components of implant systems or by using cutting-edge milling technology to fabricate custom components.
