Key Points

The aim is to evaluate the accuracy and stability of removable dies made from plant-based resins after different cleaning methods.
Digitized typodont with mandibular molar to design removable dies and hollow partial arch casts
Fabricated 54 dies using 2 plant-based resins and 1 traditional resin, cleaned with different solutions
Digitization and measurement of deviations at various intervals up to 4 weeks post-fabrication
Statistical analyses using generalized linear models and linear mixed-effects models
Interaction between resin type and cleaning solution affected dimensional and positional accuracy at initial measurement.
FD resin dies generally showed less surface and positional deviations, especially when cleaned with MES.
Positional accuracy was highest for IPA-cleaned FD dies, indicating strong stability and trueness.
Time had a minimal effect on deviations, suggesting stability over the 4-week period.
