• 1 other identifier: CEBD-CU-2018-10-01
• Study Type: interventional
• Target: 26
• Locations: 0 countries

Brief Summary

evaluation of wear behavior and patient satisfaction of monolithic zirconia and zirconia reinforced glass crowns after follow-up periods 0,3,6,12 months.

Conditions

Wear of the Natural Enamel

Outcome Measures

Primary Outcomes (1)

• wear of the antagonist natural enamel

  loss of opposing tooth structure which will be measured by 3D Profilometer

  from baseline till one year

Secondary Outcomes (1)

• patient satisfaction

  from baseline till one year

Study Arms (2)

zirconia reinforced lithium silicate glass ceramic

EXPERIMENTAL

It represent a new generation of glass ceramic material, enriched with zirconia (10% by weight), the material offers natural esthetics with successful outcome.

Other: zirconia reinforced lithium silicate glass ceramic

monolithic zirconia

ACTIVE COMPARATOR

Zirconia or zirconium dioxide (ZrO2) is a highly attractive ceramic material in prosthodontics due to its excellent mechanical properties. It is widely used to build prosthetic devices.

Other: zirconia reinforced lithium silicate glass ceramic

Interventions

zirconia reinforced lithium silicate glass ceramic OTHER

It represent a new generation of glass ceramic material. Using an innovative manufacturing process the glass ceramic is enriched with zirconia (10% by weight) for dental CAD/CAM applications for the fabrication of inlays, onlays, crowns and anterior and posterior single tooth restorations on implant abutments.
