A STUDY OF THE RELATIONSHIP BETWEEN NASION PERPENDICULAR AND THE TRUE VERTICAL LINE JEFFREY ALBERT SHELLEY JR. DEPARTMENT OF ORTHODONTICS ABSTRACT The purpose of this study is to assess the relationship between Nasion perpendicular and the true vertical line between patient groups using cephalometric analysis. Materials and Methods: Ninety-six adolescent patients comprised the sample for this study. Subjects were between 10 and 18 years old, with no major craniofacial deformity. Three groups of patients were divided in to three groups (Class I, Class II and Class III) based on their skeletal antero-posterior relationship. Pre-treatment lateral cephalometric radiographs were taken with …


Retention Of Cad/Cam Crowns Luted With A Novel Biomimetic Cement, Nan Xiang Jan 2016

Retention Of Cad/Cam Crowns Luted With A Novel Biomimetic Cement, Nan Xiang

All ETDs from UAB

Objectives: To measure the tensile strength of e.max copings cemented with resin, calcium silicate and calcium phosphate cements following thermocycling. Methods: 40 extracted non-carious mandibular premolar teeth were examined and selected using Keyence microscope for no carious cracks etc.were mounted in acrylic. The teeth were placed in a lathe and prepared to uniform dimensions (22° total taper) using a flat-end tapered diamond bur (846.11.025HP, Brasseler) and a 3mm preparation height. The surface area of the prepared surface was calculated with digital microscopy. The teeth were scanned with a Cerec 3 (Sirona) digital scanner. E.max crowns were milled using Cerec 3 …
