Fig 2 Bar graphs for the Treovance (a), Zenith LP (b), Anaconda (c), Endurant (d), and Talent (e) of the change in pullout force for repeated pulls at each angle normalized by the force for the first pull. The values for the first three devices represent a new SG per angle; the values for the Endurant and Talent represent all of the tests at a given angle for all devices and one device, respectively.
