Zirconia

Full Contour

Current industry standard for crowns is typically Full Contour Zirconia. The material composition is 100% metal-free, a feature that prevents gingival darkening and removes the possibility of exposing metallic margins if gum recession begins. To incorporate a more natural color nuance, shade specific color pigments are infused into the material to bring it closer to the desired tooth color. Full Contour Zirconia is one of the strongest restorations available for any patient who may have bruxing or grinding issues. Utilizing CAD/CAM technology, it also has a precise marginal fit that can significantly reduce chair time. 

Indications

  • Ideal for posterior crowns and bridges of any span

  • Most cost effective restoration choice

  • Limited occlusal space

Strength

  • 1200 MPa flexural strength

Benefits

  • Long-term reliability

  • Healthy tissue response

  • Hypoallergenic

  • Durability to withstand bruxism (grinding)

  • Resistant to chipping

  • Anterior Crossbite occlusion

  • Highly biocompatible

  • Tooth-colored material

  • Conventional cementation protocol

  • Adequate degree of translucency to obtain some vitality and mask dark preparations

Contraindications

  • High esthetic demand is difficult to achieve due to opacity of the material and lack of three dimensional properties

  • Can not be bonded

Preparation

  • Incisal/Occlusal Reduction: 1.0 mm (2.0 mm for bridges)

  • Facial Reduction: 1.2 mm (1.5mm for bridges)

  • Cervical Reduction: 1.0 mm reduction with bevel or shoulder margin (knife edge margin is also suitable)
