ProFatigue

ProFatigue optimizes planning and evaluation of fatigue testing for implant-supported fixed dental prostheses to improve accuracy and efficiency in assessing mechanical endurance.

Key Features:

• Optimization of fatigue testing: Optimizes planning and testing protocols for fatigue assessment of dental implants, addressing limitations of ISO 14801.
• Reduction in test specimens: Reduces the number of test specimens required compared with current ISO 14801-based approaches.
• Probabilistic analysis: Provides probabilistic references to determine endurance limits and implant reliability under cyclic loading.
• Integration of S-N curves: Incorporates load, fatigue, and stress–number of cycles to failure (S-N) curves for fatigue life evaluation.
• ISO standards analysis: Critically analyzes methodologies of ISO recommendations (2008 and 2016) to identify inherent limitations.
• Improved accuracy of estimates: Enhances accuracy of fatigue life and endurance-limit estimates through optimized planning and probabilistic methods.

Scientific Applications:

• Implant mechanical research: Supports research and development on mechanical complications of dental implants by enabling efficient fatigue testing and analysis.
• Endurance and reliability assessment: Enables assessment of endurance limits and reliability of implant-supported fixed dental prostheses under cyclic loading.

Methodology:

Incorporates load, fatigue, and stress–number of cycles to failure (S-N) curve concepts; critically analyzes ISO recommendations (2008 and 2016) to identify limitations; applies a refined approach including probabilistic estimation of endurance limits and reduced-specimen testing strategies.
