Physical And Optical Properties Of Material Used For Injection Molding, Nadia Christine Farias Machado Jan 2024

Physical And Optical Properties Of Material Used For Injection Molding, Nadia Christine Farias Machado

All ETDs from UAB

Background: This project investigates the materials used in injection molding dental resin composites which involves injecting flowable composite into a clear mold. Understanding the physical and optical properties of both the resin composite and the clear mold material is crucial for successful clinical outcomes. For the clear mold material, its translucency, curing light transmission, and rigidity are vital factors. Correlations may be present between trans-lucency and curing light transmission. For the resin composite, comparing wear, hardness, translucency, radiopacity, shrinkage stress, flexural strength, and modulus will affect mate-rial performance. Finally, the depth of cure of the material will be dependent on …


Crown Fatigue Resistance And Enamel Wear Of 3d Printed Resin Compared To Lithium Disilicate, Pranit Vasant Bora Jan 2024

Crown Fatigue Resistance And Enamel Wear Of 3d Printed Resin Compared To Lithium Disilicate, Pranit Vasant Bora

All ETDs from UAB

Purpose: The purpose of this study is to compare the wear characteristics and fatigue resistance of two dental crown materials: SprintRay Ceramic Crown, a 3D-printed resin material, and IPS™ e.Max CAD, a lithium disilicate material. Methods: This study evaluates wear and fatigue characteristics of dental crowns made from Ceramic Crown (SprintRay) and IPS e.max CAD LT (Ivoclar). For fatigue testing, custom fatigue devices were utilized to subject the crowns to cyclic loading, simulating occlusal forces. The specimens underwent 100,000 cycle intervals until 1.5 million cycles at a load of 40N of fatigue loading, with inspections conducted for signs of debonding, …
