Summary

The aim of this study is to evaluate the clinical performance of two finish line designs (feather edge and rounded shoulder) in relation with two occlusal designs (flat and planar) in endodontically treated teeth restored with zirconia crowns.

Conditions

  • Gingival Inflammation

Interventions

OTHER

Abutment with flat occlusal reduction with feather edge finish

Non vital teeth require a full coverage restoration to withstand the functional stresses and prevent any further destruction of tooth/crown complex. The zirconia all-ceramic crowns yield a high flexure strength and are used as an esthetic alternative to ceramo-metallic crowns. Several studies linked the effect of preparation designs to the survival of the restoration. Others, studied the effect of the finish line geometries as deep chamfer and shoulder on the marginal integrity of restorations. The feather edge finish line is used with zirconia crowns with limited data regarding its success. However, there is no presented research dealing with the effect of finishing line designs in combination with different occlusal reduction schemes on the marginal fit of full contour zirconia crowns.
