Workflow

Step 1. Make Toronto Bridge

1.1 Scan with AutoScan-DS-MIX

Create an order in the scan software. 

Scan the model with AutoScan-DS-MIX dental 3D scanner. 

Due to the large angles of 32 and 34, the scan bodies can be collided with each other. So install the scan body of 34 first and scan. Then replace it and install scan body of 32 and get all the data with multiple add-scan. (See pictures below.)

AutoScan-DS-MIX’s exceptional scan performance, featuring 2*5.0MP high resolution and ≤7μm high accuracy, guarantees reliable scan result, which will largely improve the design & production efficiency. 

1.2 Design in exocad

It can be seen from the color bar the matching error is less than 0.02mm.

Design the Toronto bridge in exocad.

1.3 Milling

1.4 Complete Toronto Bridge

Based on ideal scan result with excellent CAD designing and milling, the bridge fits perfect on the model. The picture shows the fit situation with only one screw assembled.

1.5 Post-processing of Bridge

  • Try-in   
  •  Metal grinding
  •    Build up opaque

Step 2. Make the Superstructure

2.1 Create an order for superstructures

#34–#44 are PFM crowns.

2.2 Scan Toronto Bridge

Scanning with AutoScan-DS-MIX, all the details were perfectly kept. 

2.3 CAD Design with exocad

Design copings from #34-#44

2.4 Post-processing of Superstructures

Printing & grinding for copings

Ceramic building & grinding

Complete solidex

Complete gingiva

In this case 34-44 were ceramic crowns, 35-36, 45-46 were solidex & gingiva.
