Mature industrial sectors (e.g., aviation) collect their real world failures in incident databases to inform safety improvements. Intelligent systems currently cause harms without a collective memory of failings. As result, companies repeatedly make the same mistakes design, development, and deployment intelligent systems. A collection system experienced (i.e., incidents) is needed ensure benef...
statement of the problem in recent decades, immediate implant placement has been proposed to eliminate undesirable consequences of conventional methods of delayed placement. in addition, because of the nature of this treatment method, a higher risk of complications such as infection and also higher failures rates may be expected purpose the aim of this study was to compare clinical outcomes of ...
