College student beats lab professionals in design competition

College student beats lab professionals in design competition using inLab software.

Dentsply Sirona is pleased to announce that a college student outperformed over 30 dental laboratory professionals in a Software Design Competition using the company’s inLab® software. The contest was recently held at the Dental Lab Owners Association of California’s (DLOAC’s) 13th Annual International CAD/CAM Expo & Symposium on November 17th-19th in Orange County, California.

Shortly after learning the software program that same morning, Zhen Yin, a student at L.A. Community College, took home the grand prize of $5,000 for his winning designs using the inLab software. “The inLab software was very easy to use and made designing each restoration quick, efficient and actually fun,” remarked Zhen. “I am very proud to say that I won this contest among so many talented and experienced laboratory professionals.”

Second and third place winners (respectively) were Goran Zarov, Owner of Accutech Dental Lab, and David De Wet, Owner of Oralart Dental Ceramics who each took home $1,500. The fourth place winner was Gary Jordan, President of Grossman Dental Lab, who won an Apple Watch. All winners achieved their winning placements by using the inLab software.

The Software Design Competition was created by Jean Chiha, Owner of North Star Dental Laboratories and Milling Center in Santa Ana, California, and President of DLOAC. “This is my last year as President of DLOAC and I was looking to do something different,” remarks Chiha. “I think all that participated really enjoyed this. I wanted to make sure that it was a very well-rounded and fair competition so I choose a wide range of judges and design software from a variety of manufacturers to ensure that all designs were judged without bias.”

All contestants were free to choose from a number of software design platforms to work on for their restorative challenges including Cercon®, exocad, 3Shape, Dental Wings and inLab. They then participated in three rounds of competition where they were tasked with designing different restorative requests within a very limited timeframe:

  • 1st Round-3-unit posterior bridge (two minutes)

  • 2nd Round-6-unit anterior bridge (four minutes)

  • 3rd Round-Full-arch upper bridge (ten minutes)

Designs were judged on speed, aesthetics, occlusion contacts and the shape of teeth. Frankie Acosta, one of the judges for the competition, weighed in on the winning design, “I think a big reason as to why Zhen came out on top using inLab was because of the simplicity of the software. Of course his designs were outstanding, but I think he ultimately won because he let the software work for him.”
