## Abstract

Methods for verifying manufacturing data are provided. In some embodiments, a method includes retrieving a fabrication data package including manufacturing data for one or more dental appliances, where the manufacturing data includes one or more treatment stages for repositioning a patient's teeth using the one or more dental appliances. The method can include determining whether there is an error in the manufacturing data of the fabrication data package. In response to a determination that there is an error in the manufacturing data, the method can include requesting a corrected fabrication data package, and transmitting the corrected fabrication data package to at least one fabrication terminal configured to execute a fabrication process for manufacturing the one or more dental appliances.

## Claims

### Claim 1

A method comprising:
retrieving a fabrication data package comprising manufacturing data for one or more dental appliances, wherein the manufacturing data includes one or more treatment stages for repositioning a patient's teeth using the one or more dental appliances;
receiving a dental treatment profile including a number of treatment stages for repositioning the patient's teeth;
determining whether there is an error in the manufacturing data of the fabrication data package, wherein the error comprises missing data for the one or more treatment stages, and wherein the determination comprises comparing the number of treatment stages of the dental treatment profile to the one or more treatment stages of the manufacturing data to identify the missing data; and
in response to a determination that there is an error in the manufacturing data:
requesting a corrected fabrication data package, and
transmitting the corrected fabrication data package to at least one fabrication terminal configured to execute a fabrication process for manufacturing the one or more dental appliances.

### Claim 2 (depends on 1)

The method of claim 1, wherein the error comprises invalid data for the one or more treatment stages.

### Claim 3 (depends on 2)

The method of claim 2, wherein the invalid data comprises inaccurate data.

### Claim 4 (depends on 1)

The method of claim 1, further comprising:
generating an error notification and transmitting the error notification to a remote terminal; and
receiving, from the remote terminal, the corrected fabrication data package.

### Claim 5 (depends on 1)

The method of claim 1, wherein the method is performed by a central manufacturing terminal that is operably coupled to the at least one fabrication terminal.

### Claim 6 (depends on 1)

The method of claim 1, wherein the manufacturing data includes a three-dimensional representation of the patient's teeth for each of the one or more treatment stages.

### Claim 7 (depends on 1)

The method of claim 1, wherein the fabrication process comprises manufacturing the one or more dental appliances via a rapid prototyping process.

### Claim 8 (depends on 1)

The method of claim 1, wherein the fabrication process comprises generating a tray data file based on the manufacturing data, and wherein the tray data file includes layout information indicating a spacing and an orientation for each of one or more mold objects corresponding to the one or more dental appliances.

### Claim 9 (depends on 1)

The method of claim 1, wherein the one or more dental appliances comprise one or more dental aligners.

### Claim 10 (depends on 1)

The method of claim 1, wherein the one or more dental appliances are each associated with a unique set of manufacturing parameters.

### Claim 11

A method comprising:
retrieving a fabrication data package comprising manufacturing data for one or more patient-customized appliances, wherein the manufacturing data includes one or more treatment stages using the one or more patient-customized appliances;
receiving a treatment profile including a number of treatment stages;
determining whether there is an error in the manufacturing data of the fabrication data package, wherein the error comprises missing data for the one or more treatment stages, and wherein the determination comprises comparing the number of treatment stages of the treatment profile to the one or more treatment stages of the manufacturing data to identify the missing data; and
in response to a determination that there is an error in the manufacturing data:
requesting a corrected fabrication data package, and
transmitting the corrected fabrication data package to at least one fabrication terminal configured to execute a fabrication process for manufacturing the one or more patient-customized appliances.

### Claim 12 (depends on 11)

The method of claim 11, wherein the one or more patient-customized appliances are each associated with a unique set of manufacturing parameters.

### Claim 13 (depends on 11)

The method of claim 11, wherein the error comprises invalid data.

### Claim 14 (depends on 13)

The method of claim 13, wherein the invalid data comprises inaccurate data.

### Claim 15 (depends on 11)

The method of claim 11, further comprising:
generating an error notification and transmitting the error notification to a remote terminal; and
receiving, from the remote terminal, the corrected fabrication data package.

### Claim 16 (depends on 11)

The method of claim 11, wherein the method is performed by a central manufacturing terminal that is operably coupled to the at least one fabrication terminal.

### Claim 17 (depends on 11)

The method of claim 11, wherein the manufacturing data includes a three-dimensional digital representation of each of the one or more patient-customized appliances.

### Claim 18 (depends on 11)

The method of claim 11, wherein the fabrication process comprises manufacturing the one or more patient-customized appliances via a rapid prototyping process.

### Claim 19 (depends on 11)

The method of claim 11, wherein the fabrication process comprises generating a tray data file based on the manufacturing data, and wherein the tray data file includes layout information indicating a spacing and an orientation for each of the one or more patient-customized appliances.

### Claim 20 (depends on 11)

The method of claim 11, wherein the one or more patient-customized appliances comprise one or more dental aligners.
