Proto-tech Research

Proto-tech Research provides unique solutions that combine accuracy and reliability with ease of use in a biorealistic environment.

Dental Materials Research Instruments

Dental  materials research instruments must simulate the oral environment to prove a material’s ability to withstand service as a dental restorative. Proto-tech engineers focus on this requirement for every design, using only high quality components and specifying durable materials.

Realistic and meaningful results are another essential attribute of dental materials instruments, so Proto-tech designs are based on engineering analysis of the biomechanical conditions and a survey of the published literature and standards of practice.  

As well, experience has shown that ease-of-use is essential in labs where a variety of technicians with varying skill levels are using the equipment. Proto-tech designs are straight-forward, and include detailed instruction manuals, video tutorials for many instruments, and on-call support.

New for 2023: Saybot - A new motion-sensitive audio player.

Another ground-breaking development from Proto-tech. Saybot plays audio from your web-based archive whenever someone enters the room. Do you need to remind study subjects of appointments or instructions? Send them home with Saybot. Update your messages online and they will be reminded when it really counts: at home. Control the volume with your cellphone through bluetooth. Find out more here.

DO YOU NEED custom fixtures for your next materials test? Let Proto-tech design them and 3-D print them of super tough nylon. The turnaround time is impressive, and the tolerances are great. We can print shapes that used to be impossible with injection modeling techniques thanks to laser sintering. Let us draft them up in Solidworks (licensed user) and print them in white or 6 bright colors. Or if you need something tougher like brass or steel, we can do that too! Call John at (971) 344-3730 for more details.



TestTouch: the new single axis testing station you control from a touchscreen interface.  Configure TestTouch for shear bond strength, tension testing, flexural strength and more and control from an open source platform that is wifi-enabled for easy uploading. Perfect for the home laboratory: TestTouch…coming soon.
