Custom aligners are often described as a simple clear orthodontic appliance, but the manufacturing process behind them involves several connected stages. From receiving patient-specific dental data to treatment planning, 3D model production, thermoforming, trimming, inspection, and packaging, every stage needs to follow a defined workflow.
For dental clinics, orthodontic practices, distributors, and private-label dental brands, understanding this process is useful when evaluating a custom aligner manufacturer. It also helps buyers distinguish between a supplier that only provides finished appliances and a dental laboratory capable of managing the complete production process.
Midway Dental Laboratory is a full-service dental laboratory founded by Mr. William Yin and located in Shenzhen, China. Established in 2016, the laboratory specializes in clear aligners, orthodontic appliances, clip-on veneers, crowns and bridges, veneers, all-ceramic restorations, implants, dentures, and other dental laboratory products. Its published workflow combines CAD/CAM technology, treatment planning, 3D model printing, and thermoforming.
1. The Process Starts With Patient-Specific Dental Data
The first step in producing a custom aligner is obtaining accurate information about the patient's teeth.
Modern dental clinics can submit digital intraoral scans directly to the laboratory. Clinics that still work with physical impressions can also use PVS rubber impressions, depending on the manufacturer's workflow.
This is an important point for international dental businesses because not every customer uses exactly the same digital system.
Midway Dental Laboratory accepts both digital scans and PVS rubber impressions. According to its published process, digital scans can go directly into treatment planning, while PVS impressions are poured into stone models and then scanned.
This gives dental professionals more flexibility when submitting cases and allows the laboratory to work with different types of source data.
2. Case Data Is Prepared for Digital Planning
Once the dental data reaches the laboratory, the next step is preparing it for treatment planning.
The laboratory needs to work from a usable digital model of the patient's dentition. The quality and completeness of the input data are important because the subsequent planning and manufacturing stages depend on this information.
For a custom aligner manufacturer, digital workflow capability is therefore more than having scanning equipment. It involves connecting patient data with treatment planning, model production, and final manufacturing.
Midway states that CAD/CAM technology plays an important role in simplifying, shortening, and improving its production process.
For overseas customers, a structured digital workflow can also make case communication easier because the clinical information can be transferred and reviewed electronically.
3. Treatment Planning Creates the Production Roadmap
After the digital model is prepared, treatment planning becomes the next major stage.
Instead of manufacturing one generic appliance, a custom aligner series is based on a planned sequence. The digital model is used to establish the intended stages of the treatment, with each stage corresponding to an aligner.
This is where the manufacturing process becomes closely connected to the clinical workflow.
Midway Dental Laboratory lists 3Shape Ortho Analyzer as its staging software. Its clear aligner workflow includes treatment planning as the first stage of its one-stop production solution.
For dental clinics, it is useful to confirm how this stage works before selecting a supplier. Questions about treatment-plan review, modification, confirmation, and communication should be answered before regular case production begins.
4. The Treatment Plan Is Confirmed Before Manufacturing
A well-organized production process should include a clear confirmation stage.
The dental professional needs to review the proposed treatment plan before the laboratory moves forward with manufacturing. This is particularly important for outsourced production, where the clinic and laboratory may be located in different countries.
Midway's published process states that after receiving an impression, the laboratory sends the treatment plan for confirmation within two days. Once the treatment plan is confirmed, the aligners move into production.
For B2B customers, this creates a defined point between digital planning and physical manufacturing.
It also makes the workflow easier to manage when a clinic needs to communicate adjustments before production starts.
5. 3D Printing Converts Digital Planning Into Physical Models
Once the treatment plan has been approved, the digital stages can be converted into physical models.
3D printing plays an important role here.
Each model represents a planned stage of the aligner sequence. The thermoforming process can then use these models as the physical form around which the aligner material is shaped.
Midway describes its clear aligner production as a one-stop process covering treatment planning, 3D printing models, and thermoforming.
This integrated process is useful for customers because multiple production stages are handled within one laboratory workflow rather than being divided among unrelated suppliers.
6. Material Selection Comes Before Thermoforming
The next step is selecting the material used to form the aligner.
Material specifications are an important consideration for dental clinics and distributors because the chosen material becomes part of the product specification for the case.
Different manufacturers may offer different material brands and options. Buyers should therefore ask for exact material information instead of relying on general descriptions such as "high-quality clear plastic."
Midway Dental Laboratory states that it offers Erkodent and SCHEU Duran+ materials and allows customers to choose between them. The company identifies both materials as being from Germany.
For long-term B2B cooperation, confirming the material at the beginning can also help maintain consistency across repeated orders.
7. Thermoforming Creates the Physical Aligner
Thermoforming is one of the most recognizable stages in the manufacturing process.
The selected thermoplastic material is heated and formed over the corresponding 3D model. After forming and cooling, the material retains the shape of the model and can then move to the finishing stage.
However, thermoforming should not be viewed as an isolated process.
The final appliance depends on the accuracy of the digital treatment plan, the physical model, the selected material, and the manufacturing parameters used during forming.
This is why a capable custom aligner manufacturer needs an integrated workflow rather than simply having a thermoforming machine.
Midway includes thermoforming as the final stage of its published treatment planning → 3D printing → thermoforming production sequence.
8. Trimming Gives the Aligner Its Final Form
After thermoforming, the aligner needs to be separated from the model and trimmed.
Trimming is a practical production detail that should be discussed with the manufacturer before placing regular orders.
Different customers may have different preferences or specifications for the edge design. A dental clinic may also need consistency across a series of aligners for the same treatment plan.
Midway's published FAQ identifies its trimming specification as option "B."
For international buyers, this is a good example of why technical specifications should be confirmed in advance rather than assuming that every manufacturer follows the same finishing method.
9. Quality Inspection Checks the Finished Appliance
A custom aligner is not ready for shipment immediately after thermoforming.
The finished appliance should be checked against the production requirements before it is packaged.
Depending on the manufacturer's internal procedures, inspection can include:
-
Overall appliance shape
-
Correspondence with the production model
-
Trimming and edge condition
-
Surface condition
-
Material consistency
-
Case identification
-
Packaging requirements
For a dental laboratory serving international customers, quality control is particularly important because any issue discovered after international shipment can create additional case-handling work.
Midway identifies reliable quality control as one of its service advantages and lists quality assurance as part of its website's "Why Us" resources.
A B2B buyer should therefore ask not only whether a supplier has quality control, but also what stages are checked and how production requirements are documented.
10. Packaging Can Be Customized for Different Business Models
After inspection, the completed aligners are organized and packaged.
For a dental clinic, packaging may focus mainly on case identification and practical handling. For distributors and private-label dental brands, packaging can become part of the product itself.
A supplier may need to accommodate:
-
Brand-specific packaging
-
Custom labels
-
Case identification
-
Product instructions
-
Customer-supplied packaging samples
-
OEM production requirements
Midway states that it can provide custom packaging when customers provide a sample. It also offers OEM/ODM solutions for clear aligner outsourcing.
This gives overseas dental businesses more flexibility when they want to outsource manufacturing while maintaining their own product presentation.

This makes the laboratory relevant not only to individual dental clinics but also to international dental businesses looking for a manufacturing partner.
What Should Buyers Ask Before Choosing a Manufacturer?
Before starting regular cooperation, buyers should clarify several practical points.
Can the supplier accept my case format?
Ask whether the laboratory accepts digital scans, PVS impressions, or both.
How is treatment planning handled?
Confirm which software is used and how the treatment plan is reviewed and approved.
What materials are available?
Ask for specific material brands and specifications.
How are the aligners trimmed?
The trimming method should be confirmed before production.
Can packaging be customized?
This matters particularly for private-label businesses and distributors.
Is OEM/ODM available?
If you are developing your own dental brand, confirm the level of customization supported.
How is international shipping handled?
A clear shipping process is important when cases are manufactured in China and delivered to overseas customers.
Why the Complete Manufacturing Process Matters
A custom aligner is the result of a connected manufacturing system.
A digital scan is only the starting point. It needs to be converted into a treatment plan, approved by the dental customer, transformed into physical models, and used in the thermoforming process. The resulting appliances then need trimming, inspection, packaging, and shipment.
This is why dental businesses should evaluate the manufacturer's complete workflow, not simply the appearance of the finished product.
Midway Dental Laboratory combines CAD/CAM technology, treatment planning, 3D printing, thermoforming, material selection, quality control, custom packaging, and OEM/ODM support. The laboratory's broader dental product portfolio also allows it to serve customers with needs beyond clear aligners.
