Purpose: To assess the flexural strength (FS), surface roughness, and color stability of additive manufactured (AM) and subtractive manufactured (SM) denture teeth materials, as well as the effect of thermocycling on these properties.
Materials And Methods: Eighty strips (20/material type; 64×10×3.3 mm) and 60 discs (15/material type; 12×4 mm) were fabricated from four different denture teeth materials (Straumann, Flexcera, Ivoclar, and Candulor).
Purpose: To compare the internal fit and marginal discrepancy of acrylic resin interim crowns fabricated by different manufacturing methods, and to test the consistency of measuring marginal discrepancy and internal fit between different measuring techniques.
Materials And Methods: A dentoform mandibular left first molar was prepared for an all-ceramic crown. Thirty-six interim crowns were fabricated and divided into three groups (n = 12): group BAC (Bis-acrylic composite, fabricated manually), group CAM (CAD/CAM polymethylmethacrylate resin, milled), and group 3DP (3D printed methacrylic oligomers, printed).
Statement Of Problem: The adaptation of interim crowns made by subtractive and additive manufacturing has not been well investigated.
Purpose: The purpose of this in vitro study was to evaluate the internal fit and marginal discrepancy of interim crowns made by different manufacturing methods.
Material And Methods: A dentoform mandibular left first molar was prepared for a ceramic crown and scanned for the fabrication of 48 stereolithical resin dies and interim crowns.
