Analysis of occupational stress, burnout, and job satisfaction among dental practitioners
Work, 2022BACKGROUND: Dental practitioners can be prone to stress because of the long working hours, high patient expectations, and work environment. OBJECTIVE: To investigate dimensions of occupational stress among dental practitioners leading to burnout and to model its causality with job satisfaction. METHODS: An analytical cross-sectional study was conducted

Asymptotic Analysis of the Stress Field in Adhering Dental Restorations
Journal of Biomechanical Engineering, 2000Polymer-based composites are widely used in restorative dentistry as alternatives to metals and ceramics to fill cavities in teeth. They adhere to the walls of the cavity in the tooth, thus forming a composite body consisting of dentine, enamel, and composite resin.

Influences of Stresses on Dental Implant Threads Using Finite-Element Analysis
Journal of Long-Term Effects of Medical Implants, 2019The objective of this finite-element analysis (FEA) study is to check the effect of stress on different types of threaded implants. To perform the FEA study of 81 models, the geometry of cancellous bone is imported and corresponding materials are set using FEA software. A common biting force is applied on the implant.

Finite element analysis of dental structures — axisymmetric and plane stress idealizations
Journal of Biomedical Materials Research, 1975AbstractThe finite element method used to study stress generated in a maxillary second premolar as a result of occlusal forces. This mathematical technique has been applied extensively in structural engineering and structural mechanics. It is well suited to the analysis of stress in teeth and dental restorations because it can closely simulate the ...

Finite Element Analysis of Stress in Bone Adjacent to Dental Implants
Journal of Oral Implantology, 2008Understanding how clinical variables affect stress distribution facilitates optimal prosthesis design and fabrication and may lead to a decrease in mechanical failures as well as improve implant longevity. In this study, the many clinical variations present in an implant-supported prosthesis were analyzed by a 3-dimensional finite-element method.

The Journal of Prosthetic Dentistry, 1971
Abstract A two-dimensional photoelastic model study of porcelain fused to gold restorations was conducted on models that were 20 times normal size, using three plastics having a ratio of the elastic moduli similar to those of the actual materials. Isochromatic and isoclinic patterns were obtained and the principal stresses were separated in critical ...

Finite Element Analysis of Stress in Dental Bridge with Implant
Journal of Biomaterials and Tissue Engineering, 2020The objective of this research was to investigate dental bridges with and without implants. Threedimensional (3D) mandible models were reconstructed by computer tomography (CT) to simulate biting behaviors. The dental implant is an important factor in dental bridge applications.

Stress analysis on the bone around five different dental implants
2001 Conference Proceedings of the 23rd Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Implantology has widespread application for dental cases these days. Although the life of this practice is short, there has been considerable progress in this field and many research laboratories and production sites have been developed in this regard.

Stress Distribution of Dental Posts by Finite Element Analysis
2011The purpose of this study was to investigate stress distribution in three types of dental posts for understanding the biomechanical effects of various posts by three-dimensional finite elements analysis (FEA). The models of the FEA were consisted of three types of posts, Co-Cr crown, premolar without crown and regional bon of mandibular resection ...
