Influence of base design on the manufacturing accuracy of vat-polymerized diagnostic casts: An in vitro study.

Statement Of Problem: Vat-polymerized casts can be designed with different bases, but the influence of the base design on the accuracy of the casts remains unclear.

Purpose: The purpose of the present in vitro study was to evaluate the influence of various base designs (solid, honeycombed, and hollow) with 2 different wall thicknesses (1 mm and 2 mm) on the accuracy of vat-polymerized diagnostic casts.

Material And Methods: A virtual maxillary cast was obtained and used to create 3 different base designs: solid (S group), honeycombed (HC group), and hollow (H group).
