E4D chairside CAD/CAM restorations

Fig. 1: Patient presents with crown missing from tooth #9

Fig. 2: E4D Dentist System is used to take a digital impression, then the restoration is designed using E4D DentaLogic Software

Fig. 3: An IPS Empress DAC Multi A1 restoration is milled and custom characterized using IPS Empress Universal Stains

Figs. 4: A patient with amalgam restoration and recurrent caries on the mesial of tooth #13. The E4D Dentist System was used to make a digital model, and restorations were milled out of IPS e.max CAD HT A2 blocks.

Figs. 5: A patient with amalgam restoration and recurrent caries on the mesial of tooth #13. The E4D Dentist System was used to make a digital model, and restorations were milled out of IPS e.max CAD HT A2 blocks

Figs. 6: A patient with amalgam restoration and recurrent caries on the mesial of tooth #13. The E4D Dentist System was used to make a digital model, and restorations were milled out of IPS e.max CAD HT A2 blocks.

Figs. 7: With the strength of IPS e.max, predictable restoration of second molars using the E4D Dentist System is possible

Figs. 8: With the strength of IPS e.max, predictable restoration of second molars using the E4D Dentist System is possible

Figs. 9: With the strength of IPS e.max, predictable restoration of second molars using the E4D Dentist System is possible

Figs. 12: After a diagnostic wax-up was made, the teeth were prepared and temporized.

Figs. 13: After a diagnostic wax-up was made, the teeth were prepared and temporized

Fig. 14: The E4D Dentist System clone feature copies the occlusion and anatomy of the temporaries exactly

Fig. 16: Restorations are milled out of B1 e.max CAD LT, prepared and seated

Fig. 15: The E4D Dentist System software, DentaLogic, enables the clinician to superimpose the temporary “clone” model over the restoration design to determine accuracy
