Weibull Analysis to Evaluate the Lifetime of Dental Implants

Abstract

A product's lifespan can be predicted using Weibull analysis. Because it enables predictions based on a small sample of data from experiments or field trials, this statistic is helpful. Weibull analysis was used to fit the sample data to a Weibull distribution. The chance of survival can be calculated at any moment if the data are fitted to a Weibull distribution. In order to provide several solutions to the issues below, we apply this analysis to the lifetime assessment of dental implants in this study:

1. When do dental implants begin to deteriorate?


2. How long should a dental implant warranty last?

• Do dental implants demonstrate early failure (such as infant mortality)?

1. Are dental implants prone to failure at random over time, or are failure traits more closely linked to wear?


2. When do the majority of dental implants fail?
