Restorative Materials

HSZ = High Strength Zirconia

• Manufacturer: Argen HT Multi ZR+

  • Strength: 1200 MPa

  • Uses:  -Single units where stump shade needs blocked out (Shade 2X darker than restorative shade)

  • Multiple units and bridgework over 3

  • Highly esthetic for multiple unit bridgework, implant or otherwise

  • Not recommended use:  None

Plus Zirconia’s

HTZ+ = High Translucent Zirconia+

• Manufacturer: Ivoclar Emax Zircad MT Multi and Emax Prime Esthetic

  • Strength: 650-850 MPa

  • Uses:  -Single units where stump shade is not an issue (not more than one shade different than restorative shade)

  • 3-unit bridges (single pontic) joint size 7-9 mm

  • Highly esthetic, has more incisal translucency

  • Will match Emax lithium disilicate (Veneers)

  • Not recommended use:  -Bridges greater than 3 unit or small joint size

  • Implants abutment.   There will be show through unless more than 1.5 mm thick.

HSZ+ = High Strength Translucent Zirconia+

• Manufacturer: Ivoclar Emax Zircad Prime

  • Strength: 650-1100 MPa

  • Uses:  -Single units where stump shade needs blocked out (Shade 2X darker than restorative shade) 

  • Multiple units and bridgework over 3

  • Highly esthetic for multiple unit bridgework, implant or otherwise

  • Not recommended use: None

Downsides:

• Can be too translucent at incisal 1/3. This depends on how the restoration can be aligned in the puck to avoid low value from too much incisal.

• If bridge joints are too high in the puck they become weaker due to the variation of the MPa there we avoid placing joints too high up in the puck. Incisal is only 650 MPa.

• Manufacturer: Aidite Pro

  • Strength: 750-1200 Mpa

  • Uses:  -Single units where stump shade needs blocked out (Shade 2X darker than restorative shade)

  • Multiple units and bridgework over 3

  • Highly esthetic for multiple unit bridgework, implant or otherwise

  • Not recommended use:  -None

Downsides:

• Thin crowns may need pre-shaded to match pontics

• Avoid placing joints too high up in the puck.
