متن کاملTorque Removal Evaluation of Screw in One-Piece and Two-Piece Abutments Tightened with a Handheld screwdriver
Introduction: Some clinicians use a handheld screw driver instead of a torque wrench to definitively tighten abutment screws. The aim of this study was to compare the removal torque of one-piece and two-piece abutments tightened with a handheld driver and a torque control ratchet. Methods: 40 ITI implants were placed in acrylic blocks and divided into 4 groups. In groups one and two, 10 ITI one...
متن کاملNd:YAG capsulotomy rates after use of the AcrySof acrylic three piece and one piece intraocular lenses.

متن کاملStudy on implementation of one-piece lean line design using simulation techniques: A practical approach
This paper discusses the simulation study carried out for proposing one-piece lean line layout with features of Lean Manufacturing. The lean initiatives that can be addressed are, introducing Kanban replenishment sys-tem, better work-in-process, changing the layout, visual management techniques, standardized work for the re-duction of cycle time, number of workers, number of setups. To improve ...
