A New Full Digital Workflow for Fixed Prosthetic Rehabilitation of Full-Arch Edentulism Using the All-on-4 Concept.

(1) : Recent digital workflows are being developed for full-arch rehabilitations supported by implants with immediate function. The purpose of this case series is to describe a new digital workflow for the All-on-4 concept. (2) : The patients were rehabilitated using the All-on-4 concept with a digital workflow including computerized tomography scanning, intra-oral scanning, and CAD-CAM production of the temporary prosthesis, with the 3D printing of stackable guides (base guide, implant guide, and prosthetic guide).

Oral health of people with emotional disorders: A systematic review and meta-analysis.

Objectives: This study aims to determine the association between severe mental disorders and oral health among individuals over 18 years of age.

Methods: An electronic search was conducted in six electronic databases and gray literature. Qualitative and quantitative analyses were performed on studies that met the inclusion criteria.

Failure load and shear bond strength of indirect materials bonded to enamel after aging.

This study evaluated the failure load and the shear bond strength of 4 block materials indicated for computer-aided design/computer-aided manufacturing (CAD/CAM) of dental veneers: lithium disilicate, feldspathic ceramic, polymer-infiltrated ceramic, and nanohybrid composite. The tested hypothesis was that the material that combined an elastic modulus similar to that of enamel with the highest bond strength values would present the highest failure load. From prefabricated CAD/CAM blocks, disc-shaped specimens (6.

Identification and recombinant expression of an antimicrobial peptide (cecropin B-like) from soybean pest .

Background: Insects can be found in numerous diverse environments, being exposed to pathogenic organisms like fungi and bacteria. Once these pathogens cross insect physical barriers, the innate immune system operates through cellular and humoral responses. Antimicrobial peptides are small molecules produced by immune signaling cascades that develop an important and generalist role in insect defenses against a variety of microorganisms.

Mechanical performance of monolithic materials cemented to a dentin-like substrate.

Statement Of Problem: Studies on the mechanical behavior of restorative materials bonded to tooth structure and considering the properties of the material and the bonding between both substrates are lacking.

Purpose: The purpose of this in vitro study was to evaluate the hardness, fracture toughness, load-to-failure, cyclic fatigue, and stress distribution of 4 computer-aided design and computer-aided manufacturing (CAD-CAM) materials when bonded to a substrate similar to dentin (G10).

Material And Methods: Disks (11×1.

Use of radioguided surgery in abdominal wall endometriosis: An innovative approach.

Endometriosis is characterized by the presence of endometrial glands and stroma outside the uterine cavity. The occurrence of endometriosis in the anterior abdominal wall is often associated with previous cesarean section, once the spread of endometrial cells during the surgical procedure is a biologically fact possible. A 43-year-old patient, with cesarean section history and pelvic endometriosis diagnosed for over 10 years, presented with progressive abdominal pain.

Surface enhancement Raman scattering of tautomeric thiobarbituric acid. Natural bond orbitals and B3LYP/6-311+G (d, p) assignments of the Fourier Infrared and Fourier Raman Spectra.

Surface enhancement Raman scattering (SERS) of two tautomer of thiobarbituric acid was obtained using silver and gold nanoparticles. Large band enhancement in the region of the ν(C=S), ν(C=C), δ(CH2), and δ(CNH) vibrational modes was found. Natural bond analysis of the tautomer species revealed expressive values of charge transfer, principally from lone pair electron orbitals of the S, N, and O atoms.
