Effect of thickness on the translucency of machinable and printable ceramic-glass polymer materials.

Objectives: To assess the translucency of machinable and printable ceramic-glass polymer materials with different thicknesses.

Methods: Five ceramic-glass polymer materials were tested: one 3D-printable material, Permanent Crown resin (3D), two machinable materials available at low translucency (LT) and high translucency (HT) levels, VITA Enamic (VE) HT/LT, and Cerasmart 270 (CS) HT/LT. A total of 100 specimens were produced across 10 subgroups (n = 10) with thicknesses of 1 mm and 1.

A comparison of the shear bond strength between denture teeth and denture base resins manufactured either conventionally or with a 3D printer.

Statement Of Problem: Limited information is available on the shear bond strength (SBS) between denture teeth and denture base resins fabricated using a stereolithography (SLA) 3-dimensional (3D) printer.

Purpose: The purpose of this in vitro study was to evaluate the SBS between denture teeth and the denture base resins produced with the conventional method and with a 3D printer.

Material And Methods: Conventional or 3D printed denture teeth were included in the study.
