Current Insights on Fiber Posts: A Narrative Review of Laboratory and Clinical Studies.

Purpose: The aim of this study was to review the literature related to the clinical performance and laboratory findings regarding fiber posts, as well as the cementation technique employed with their use.

Materials And Methods: A literature search was performed using an electronic database, PubMed/Medline, between 2010 and 2023. The terms used were "intra coronal post, fiber post, post cementation, and post length".

Influence of Framework Material and Posterior Implant Angulation in Full-Arch All-on-4 Implant-Supported Prosthesis Stress Concentration.

This study evaluated the influence of distal implants angulation and framework material in the stress concentration of an All-on-4 full-arch prosthesis. A full-arch implant-supported prosthesis 3D model was created with different distal implant angulations and cantilever arms (30° with 10-mm cantilever; 45° with 10-mm cantilever and 45° with 6-mm cantilever) and framework materials (Cobalt-chrome [CoCr alloy], Yttria-stabilized tetragonal zirconia polycrystal [Y-TZP] and polyetheretherketone [PEEK]). Each solid was imported to computer-aided engineering software, and tetrahedral elements formed the mesh.

Effect of Consecutive Firings on the Optical and Mechanical Properties of Silicate and Lithium Disilicate Based Glass-Ceramics.

Purpose: To evaluate the effect of multiple firings on the optical and mechanical properties of two dental CAD/CAM glass-ceramics.

Materials And Methods: A total of 45 specimens of each lithium disilicate-LD (IPS E.max CAD, Ivoclar Vivadent) and zirconia lithium silicate-ZLS (Vita Suprinity, Vita Zahnfabrik) material were prepared in a disk shape.

Influence of thickness and incisal extension of indirect veneers on the biomechanical behavior of maxillary canine teeth.

Objectives: To analyze the influence of thickness and incisal extension of indirect veneers on the stress and strain generated in maxillary canine teeth.

Materials And Methods: A 3-dimensional maxillary canine model was validated with an strain gauge and exported to computer-assisted engineering software. Materials were considered homogeneous, isotropic, and elastic.

Comparative three-dimensional finite element analysis of implant-supported fixed complete arch mandibular prostheses in two materials.

Background: The increase of requests for implant-supported prosthesis (ISP) with zirconia as infrastructure has attracted a lot of attention due to its esthetics, biocompatibility, and survival rate similar to metallic infrastructure. The aim of this study was to evaluate the influence of two different framework materials on stress distribution over a bone tissue-simulating material.

Materials And Methods: Two ISP were modeled and divided into two infrastructure materials: titanium (Ti) and zirconia.
