Abstract: ABSTRACT Aims and Hypothesis: The objective of this study was the design and testing of a Prototype Computer Numerical Control (CNC) dental handpiece. We predicted that the CNC Prototype would be more accurate than the human participant prosthodontists in clinical simulation. Materials and Methods: A Prototype CNC dental handpiece was developed from off the shelf components, assigned 100 ... read moretypodont teeth (#18) for submission and 10 practice teeth. Single operator. Five prosthodontists, given 20 typodont teeth (#18) for submission and 10 for practice. Finished preparations were scanned with 3M True Definition® intraoral scanner outside of typodont, compared with Geomagic Control for RMSE. Results: RMSE Prototype (N=100) was 0.40mm. RMSE Prosthodontists (N=100) was 0.55mm. One sided T test, mean difference -.15mm (p
