Manufacturing Hawley Retainers on 3D Printed Models
Produce Orthodontic Models for Wire Retainers at Scale
Hawley retainers can be produced digitally by manufacturing the appliance over a 3D printed model, greatly improving efficiency and reducing turnaround time. Now any lab or practice can add this valuable service with little initial investment and produce retainers in-house.
The Workflow for Making Hawley Retainers on 3D Printed Models
Collect patient anatomy digitally using an intraoral scanner, or scan a physical model or impression using a desktop scanner.
Import the scan data into CAD software to build the models and, if needed, remove brackets virtually.
3. 3D Print
Prepare the 3D models for 3D printing using PreForm software before sending them to the Formlabs printer.
Wash, dry, and post-cure printed parts using Form Wash and Form Cure.
5. Apply Separator
The separating medium prevents the printed model from binding to the acrylic retainer during the acrylic polymerization process.
6. Create the Wire Frame
Use wire-bending pliers to form the arch wire and contour it to the patient’s dentition.
7. Apply Acrylic
Use the same techniques you would with traditional stone models to apply acrylic to the model.
Smooth all surfaces, then apply a wax coat to impart a glossy finish.
3D Printing Models for Hawley Retainers With the Form 2
Fast and Cost-Effective Production
3D printing dental models must be efficient, fast, and reliable. With the Form 2, print large builds overnight and smaller, faster builds during the day to reduce labor needs and maximize output. As production needs evolve, scale up without spending tens of thousands of dollars for each additional unit.
Print Capacity and Speed
|5 maxillary retainer models||5 h 11 min|
|Maximum number of models per build||10|
|Models printed in an 8-hour working day and overnight build||15|
What Our Customers Say About Working With the Form 2
“The Form 2 is very reliable; we call it a workhorse. We know when we go home at night that when we come in in the morning, everything will be printed. There's not going to be a failure; everything will be there. Because of that, we can build our business around them” – Sean Thompson, Adv.Prosth/Adv.Orth./DIP.PS.(dist) M.P.T. M.M.U./L.O.T.A., founder and director at Ashford Orthodontics
One Printer, Many Dental Indications
The Form 2 enables cost-effective, mass-customized digital production of a wide range of dental products.
