Michael Tchida of Forest Lake is a member of a team selected as finalists in a competition for student innovators at North Dakota State University.
The team designed and built an artificial jaw assembly that imitates the physical and mechanical properties of the human jaw, using a ceramic composite and a fleshy shell to mimic the properties of gums.
A junior majoring in zoology, he is the son of Michael and Mary Lou Tchida. The other team members are Joe Hedlof of Willmar and Andrew Dalman of Minneapolis. Their team, “Microventure Jaw Research,” competed in the tangible goods category.
The next round of competition includes a formal presentation at NDSU.
Winners will be named on Feb. 28. The winning entry in each category will receive a $5,000 prize.
