Purpose: To compare the effects of fabricating methods of custom monoblock mandibular advancement devices (MADs) on usability and efficacy in patients with mild and moderate obstructive sleep apnea (OSA).
Materials And Methods: Digitally fabricated custom MADs (dMADs) were produced for 11 OSA participants who had previously used conventionally fabricated custom MADs (cMADs). The participants answered a modified usability questionnaire for both MADs, and the average scores that were given to the questionnaire were evaluated by age, sex, and body mass index (BMI), and the scores of cMADs and dMADs were compared.
Custom mandibular advancement devices (MADs) can be fabricated by using either conventional processes or computer-aided design and computer-aided manufacturing (CAD-CAM). The CAD-CAM technique involves digitizing the dental arches of the patients, designing by using a dental CAD software program, and additive manufacturing with a suitable material. This article describes the steps of the design of a custom MAD by using an open-source nondental CAD software program and of the fabrication with additive manufacturing.

The steps included defining the margins, establishing the cement interval value, completing the virtual modeling of the crown, and checking the proximal and occlusal contacts by using color mapping.

Purpose: The purpose of this in vitro study was to evaluate the effects of the different sintering protocols and dipping times on the CIELab color parameters, color difference (ΔE), translucency parameter (TP), opalescence parameter (OP), and contrast ratio (CR) of monolithic zirconia.
Statement Of Problem: How the optical properties of zirconia restorations are affected by their differing processing techniques is unclear.
Purpose: The purpose of this in vitro study was to evaluate the effects of 5 different fabrication techniques on the optical properties of zirconia-based systems, including the color difference between the corresponding shades (ΔE∗, ΔE), translucency parameter, opalescence parameter, and fluorescence (ΔE∗-FL).
Material And Methods: Sixty zirconia disks (IPS e.
Purpose: To evaluate shear (SBS) and microtensile (μTBS) bond strengths of zirconia cores veneered using different fabrication techniques.
Materials And Methods: Seventy-five IPS e.max ZirCAD plates were fabricated and divided into three groups according to the following veneering techniques: layering, pressing, and CAD-on.
Objective: The aim of this study was to evaluate the effect of different surface treatments [sandblasting, Erbium:Yttrium-Aluminium-Garnet (Er:YAG), and femtosecond lasers] on the shear bond strength (SBS) of the CAD-on technique.
Background Data: Although demand for all-ceramic restorations has increased, chipping remains one of the major problems for zirconia-based restorations.
Materials And Methods: Forty yttrium-stabilized tetragonal zirconia polycrystalline (Y-TZP) zirconia plates (IPS e.
Purpose: To investigate the influence of accelerated artificial aging on the color stability of three different inlay restorations produced with a CAD/CAM system.
Materials And Methods: Thirty non-carious human mandibular molar teeth were used. The teeth were embedded in autopolymerizing acrylic resin blocks.
