Fluoride Release, Recharge, And Re-Release From Four Orthodontic Bonding Systems, Amy Bouvier
Student Theses, Dissertations and Capstones
A thesis submitted to the College of Dental Medicine of Nova Southeastern University of the degree of Master of Science in Dentistry.
Objectives: To determine the amount of initial fluoride release from four orthodontic bonding systems over a period of four weeks, and then to subject these materials to an external source of fluoride for recharge in order to measure the amount of fluoride re-release over another four-week interval. Additionally the surface morphology of these materials was analyzed under the scanning electron microscope in order to identify microscopic changes in the materials that may have occurred during the experiment. Methods: …
Effects Of Synthetic Cortical Bone Thickness And Force Vector Application On Temporary Anchorage Device Pull-Out Strength As Related To Clinical Perspectives Of Practicing Orthodontists, Ira Rothstein
Student Theses, Dissertations and Capstones
December 2011.
A thesis submitted to the College of Dental Medicine of Nova Southeastern University of the degree of Master of Science in Dentistry.
Background: Temporary anchorage devices (TADs) provide a versatile means by which orthodontic anchorage can be established without the need for patient compliance and complex force systems. Their use is predicated on their ability to remain stable throughout the course of treatment in which they are needed. This has been shown to be the result of "primary stability" which is achieved through mechanical interlocking of the screw threads with the surrounding bone immediately upon placement. Therefore, evaluating …
