Highlights

The shortage of orthodontists and orthodontic technicians are the worldwide issue [1,2,3]
The results showed that no matter for the maxillar lingual retainer or the mandibular lingual retainer, the digital method (B2= 5.3±0.67, B4= 4.5±0.53) was significantly faster than the conventional method (B1= 20.0±2.91, B3= 9.7±0.67)
We showed that the digital method was faster in fabricating maxillar (B2= 5.3±0.67) and mandibular (B4= 4.5±0.53) lingual retainer than the conventional method in fabricating maxillar (B1= 20.0±2.91) and mandibular lingual retainers(B3= 9.7±0.67)

Summary

Introduction

The shortage of orthodontists and orthodontic technicians are the worldwide issue [1,2,3]. The systematic labor shortage makes the total number of orthodontic and orthodontic technician number limited. In the U.S, it is expected to transform the workplace over the 15 to 20 years as the gap between baby boomers and entrants of collegeeducated workers widens due to the boomers’ mass retirement [2]. It was estimated that by the year 2020 one out of every two people in the U.S will be older than 50. Study result from Japan showed that medical access to specialist orthodontic services might be limited in areas other than urban districts and the regional inequalities of specialist orthodontists are high [3]
