SHELL

Nacera Shell è la zirconia opaca bianca o precolorata adatta alle sottostrutture da ceramizzare.

Proprietà del materiale - indicato per diverse applicazioni: monoliti, ceramizzazione e a ponti fino a 14 elementi -Uniformità di colore e brillantezza: Pearl1 elevata traslucenza e stabilità: 1500MPa HV 1300 Naturale traslucenza che aumenta l'estetica del monolite -Perfetta calzabilità al modello

 

ISTRUZIONI PER L'USO GUIDA ALLA SINTERIZZAZIONE

Resistenza a flessione

Resistenza a flessione su 4 punti (MPa secondo DIN ISO 6872). Un'elevata resistenza a flessione significa una migliore stabilità della zirconia quando sottoposta a carico masticatorio.
