The effect of locked screw angulation on the biomechanical properties of the S.P.S. Free-Block plate
(2013-03-27)
Objectives: Among the locked internal fixators is one denominated S.P.S. (Synthesis Pengo System) Free-Block, which was designed with a locking ring that allows the screw to be locked and positioned obliquely. Due to the ...

Influence of Liquid Lubrication on the Screw-Joint Stability of Y-TZP Implant Abutment Systems
(2017-12-01)
Purpose: To evaluate the effectiveness of abutment screws coated with liquid Vaseline on the screw-joint stability of yttria-stabilized tetragonal zirconia (Y-TZP) abutment systems. Materials and Methods: Forty Y-TZP ...
NEW COUPLING SYSTEM FOR INTERFERENCE SCREWS: BIOMECHANICAL RESISTANCE TO TORSION
(ATHA COMUNICACAO & EDITORA, 2011)
Objective: To introduce a new coupling system between screw driver and interference screw, and biomechanical tests that validate the safety of its application. Methods: The new system was submitted to biomechanical torsion ...
The Effect of Repetitive Pilot-Hole Use on the Insertion Torque and Pullout Strength of Vertebral System Screws
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Study Design. In vitro biomechanical investigation of the screw-holding capacity. Objective. To evaluate the effect of repetitive screw-hole use on the insertional torque and retentive strength of vertebral system screws. ...
THE PHOTOELASTIC ANALISYS OF VERTEBRAL FIXATION SYSTEM SCREWS
(ATHA COMUNICACAO & EDITORA, 2009)
Introduction: The photoelasticity is used for assessing the tensions/deformations involved in photoelastic materials when submitted to a given load by the observation of optical effects. The screw performance and mechanical ...
Effect of implant connection and restoration design (screwed vs. cemented) in reliability and failure modes of anterior crowns
(Wiley-Blackwell, 2011-08-01)
The mechanical performance of cemented or screw-retained implant-supported crowns with an internal or external configuration is yet to be understood. This in vitro study evaluated the effect of screw-retained and cement-retained ...
