Printed Models for Clinics and Dental Labs

Clinics and dental labs print two very different things. One is a model: a jaw, a vessel, a bone, used to look, to teach, or to explain. The other is a piece that enters a treatment, such as a surgical guide, a splint, or a model that sets an appliance. The first can be a careful shop job. The second is a device workflow, with a named resin, a validated printer, a cleaning process, and a record. Mixing them is how a useful model becomes an unreviewed medical object.

Questions that keep the line clear

Ask who is responsible for the clinical decision. A printer operator is not that person by default. Ask what accuracy the case needs, and measure a known feature instead of trusting the slider in the software. Ask which resin is cleared for mucosal contact if contact is even possible. Model resins can look identical to a certified bottle and still be the wrong bottle.

3D Catia does not supply instructions for making implants, guides, or anything that touches a patient. If that is the job, work with the lab and the manufacturer process that already carries that responsibility. Use the desk notes to understand the questions, not to skip them.

• Label display models so they are not later reused as devices.
• Keep scan files and print settings with the case number.
• Do not sterilize a part unless the resin maker says that cycle is allowed.
• Sunlight continues to cure some resins. Store them in the dark.
