Sequential calculation of torque in procedure of twin screw extrusion
The drug making resreach has accentuated on extrusion technology for a long time. The advance of drug bioavailibility, bead manufacturing and granulation is assured by extrusion procedures. There are also diverse effects in resereches with respect to the use of process understanging as a tool in quality management. Many initiatives of FDA such as PAT and QBD are getting accepted. In this survey...
متن کاملA comparison of screw insertion torque and pullout strength.
PURPOSE Pullout strength of screws is a parameter used to evaluate plate screw fixation strength. However, screw fixation strength may be more closely related to its ability to generate sufficient insertion because stable nonlocked plate-screw fracture fixation requires sufficient compression between plate and bone such that no motion occurs between the plate and bone under physiological loads....
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 کاملThe effect of insertion angle on orthodontic mini-screw torque
BACKGROUND Primary stability is an important factor for the clinical success of orthodontic mini-screws. The present study made an attempt to evaluate the effect of insertion angle changes on the maximum insertion and removal torque of orthodontic mini-screws. MATERIALS AND METHODS In this experimental study, 72 mini-screws (Dual Top Anchor System, Jeil, 1.6 mm diameter, 8 mm length) were use...
متن کاملInsertion torque, pull-out strength and cortical bone thickness in contact with orthodontic mini-implants at different insertion angles.
This study aimed to evaluate biomechanical behaviour of inclined orthodontic mini-implants by analyzing its insertion torque (IT), axial pull-out strength (APS), and cortical bone thickness in contact with mini-implant (CBTC). A total of 102 mini-implants were inserted at 90 degree, 60 degree, and 45 degree to the surface of synthetic bone. Peak IT was measured, and the mini-implants were align...
