Operatory Turnover Standard. Built a tray setup and turnover sequence that prepares the next 3 appointments during quiet periods rather than after each patient. Turnover fell from 12 minutes to 6, recovering roughly 90 minutes of clinical time a day across 3 dentists.
Supply Usage Tracking. Tracked consumption across 90 clinical items over 6 months and reset ordering to match real usage rather than habit. Supply spend dropped 16% with no stockouts, and expired material write-offs stopped.
Radiograph Retake Reduction. Reviewed a quarter of retakes to find the sensor positioning errors behind most of them, then built a positioning reference card for the operatories. The practice retake rate fell from 6% to under 2%.
