THE RESTORATIONS WITH TORONTO BRIDGE USING AUTOSCAN-DS-MIX DENTAL LAB 3D SCANNER

Posted by ADAE Team on

With the launch of the AutoScan-DS-MIX dental lab 3D scanner, its superior performance and precision accuracy have been trusted by many dental laboratories, who have used this desktop lab scanner to complete complex cases. Today’s case is the Toronto bridge restoration, completed using the AutoScan-DS-MIX.

Case Profile

Implant sites: #46, #44, #42, #32, #34, #36.

Implant system: #32, #42, Nobel system. #34, #36, #44, #46 Dentium system.

Restoration type: Toronto bridge

Material: Titanium

Restorations: #34~#44, ceramic crowns. #35~#36, #45~#46, solidex resin crowns. 

Color: #32~#42, A2; #43~#46, A3. 

Case partner:Jiahong DentalLab; Shenzhen GoodFeeling.

Working Process

1, Toronto Bridge 

1.1 Using AutoScan-DS-MIX dental lab 3D scanner to capture the data of model

Fig 5:Create order in software.

Fig 6,7,8: Scan the model with AutoScan-DS-MIX dental 3D scanner. Due to the large angles of #32 and #34, the scan bodies can collide 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 by using the add-scan feature.

Fig 9,10,11: 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 Exocad Design – Matching in exocad

Fig 12: It showed from the color bar that the matching error is less than 0.02 mm. 

Fig 13: All the matching errors of scan bodies are less than 0.02 mm

2, Make the superstructures

2.1, Create an order for superstructures in software 

Fig 26: Create order with #34~#44 were PFM crowns. 

Fig 27,28,29: Scanning with AutoScan-DS-MIX dental lab 3D scanner, all the details were perfectly recorded. 

2.2, CAD Design with exocad

Fig 30,31,32,33:In this case #34~#44 were ceramic crowns, #35~#36, #45~#46 were solidex resin crowns with gingiva,they were all designed using exocad. 

2.3, Post-processing of Superstructures

Fig 34,35,36: Printing and grinding

Fig 37,38,39: Ceramic building and grinding

Fig 40,41,42:Complete solidex resin crowns

Fig 43,44:Complete gingiva

3, Completion the whole case with Toronto bridge

Summary

In this case, the dentist would like to reconstruct the occlusion with the Toronto bridge and upper restorations on the implant bodies. The quality of the scanning data is extremely important in such cases. A slight deviation may cause the Toronto bridge to fail to place completely in the mouth, further leading to the long-term instability of the upper restorations. AutoScan-DS-MIX dental lab 3D scanner features excellent detail, brilliant precision, and high efficiency; it can be widely used in dental indications such as implant abutments, implant bar pillars and implant bridges.
