Stress Analysis of Porous Rooted Dental Implants

Journal of Dental Research, 1976
A two-dimensional plane stress finite element analysis of porous rooted dental implants was performed. The results of this analysis were compared to results obtained from mechanical tests performed on actual implanted specimens. The appropriate selection of interface material properties was shown to be highly significant.

An analysis of stresses in a dental implant system

Journal of Biomechanics, 1981
Abstract Successful replacement for missing teeth is one of the most complex problems facing the dental profession. Although many different types of dental implants are now available, their performance in restoring masticatory function is still limited and the subject of much controversy.

Stress analysis of dental implants

Journal of Dental Implants, 2014
Natural teeth consist of the crown and the root. Due to periodontal disease or by an injury, a natural root may be damaged, and it may be incapable of supporting the teeth and bear chewing forces. Under these circumstances, the root may be replaced by an implant.

Homogenized stress analysis in a dental implant system

Journal of Medical Engineering & Technology, 1997
In this study, the stress state occurring at each trabecular due to three different types of dental implant is investigated by a homogenization technique, in which the trabecular structure is assumed to be composed of repeating hexagonal units. This technique helps make a proper material model of bone and to analyse such a non-homogeneous structure at ...

Asymptotic Analysis of the Stress Field in Adhering Dental Restorations

Journal of Biomechanical Engineering, 2000
Polymer-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.

Comparative analysis of stress in a new proposal of dental implants

Materials Science and Engineering: C, 2017
The purpose of this study was to compare, through photoelastic analysis, the stress distribution around conventional and modified external hexagon (EH) and morse taper (MT) dental implant connections. Four photoelastic models were prepared (n=1): Model 1 - conventional EH cylindrical implant (Ø 4.0mm×11mm - Neodent®), Model 2 - modified EH cylindrical ...

Finite Element Analysis of Stress in Bone Adjacent to Dental Implants

Journal of Oral Implantology, 2008
Understanding 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.

Analysis of occupational stress, burnout, and job satisfaction among dental practitioners

Work, 2022
BACKGROUND: 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

Experimental stress analysis of dental restorations. Part VII. Structural design and stress analysis of fixed partial dentures

The Journal of Prosthetic Dentistry, 1970
lh e principles of engineering design should be used in the structural design of fixed partial dentures as well as the biologic, esthetic, and mechanical restrictions of the oral cavity.’ The conventional structural design is primarily concerned with the analysis of given structures, using the conventional equations of strength of materials.2z 3 ...
