The SprintRay Pro 2 is a 3D printer that allows me to quickly create appliances for patients. I use it for such things as splints and making immediate teeth when doing implants. It’s one of the most cost-effective and time-efficient ways of doing things.
What’s good about it
At the moment, I only use the printer to create temporary items, though there are new compounds coming out that are suitable for permanent applications. The world of 3D printing is evolving quickly, and new polymerised materials have far more strength compared to what is used at present.
It’s a versatile printer I initially used to make simple things such as retainers, trays and chair-side splints for people clenching and grinding their teeth. I now use it when doing a smile design for a patient and print a full set of mock teeth. I also use it when a patient needs a temporary denture. I can have it printed in about 45 minutes.
When patients are having a full arch fitted, the SprintRay can make a transitory denture to wear until the final solution is ready to fit. This allows patients to walk around and interact with people without any embarrassment.
Single tooth implants can mean a wait of four months for integration and healing. In these cases, I can print and fit a temporary tooth straight away. Patients really appreciate this, particularly if it’s a front tooth.
What’s not so good
The problem with this unit and a lot of similar machines is that it’s restrictive in terms of materials that can be used. Before you purchase a 3D printer, you should consider the consumables that will be compatible and that they fit with
your expectations.
