CRISTINA BORTUN, ANGHEL CERNESCU, NICOLAE GHIBAN, NICOLAE FAUR, BRANDUSA GHIBAN, OTILIA GOMBOS, ANGELA CODRUTA PODARIU Durability Evaluation of Complete Dentures Realized with “Eclipse Prosthetic Resin System”


Abstract:
The present study is focused on a multidisciplinary research, regarding the durability of complete dentures realised from light curing UDMA resins. Absence of methyl, ethyl, propyl or butyl monomers from their composition is responsible for their good utilization, because they do not generate contact allergies. For testing there was used Eclipse Prosthetic Resin System (DENTSPLY International Inc. - DeguDent GmbH, Hanau Germany), which consists of: Base Plate, Set-Up and Contour Resins. Using the technology recommended by the producer, there were realized nine samples, which were mechanically tested with Zwick Roel equipment. A pair of finite prostheses, realized with the help of this system, was used by finite elements method (3D scanning, software Pixform Pro Program, program CAD - Ansys Workbench (ANSYS Multiphysics) or ABACUS / CAE version 6.6.1). Static analyses for stress and strain were based on „reverse engineering” method. In the end, experiment certification took place also through fatigue tests (Walter-Bai Dynamic Testing Machine). The following mechanical parameters were determined after testing: Young’s modulus of elasticity: 2908.45 MPa, ultimate tensile strength Rm= 59.49 MPa; total elongation At= 4.582 %, at a medium force value of 1203N. Stress and strain analysis of the denture subjected to different loadings, was revealed through chromatic spectres on denture virtual models. The warm colours indicate the areas with problems. By finite elements method one can realize noninvasive numerical procedures, which reveal the risk areas that can lead to dentures’ fracture; thus, one can correct and improve the complete dentures quality. Following the fatigue tests, we may consider that mechanical properties of Eclipse allow a five years warranty for complete denture. Key words: complete dentures, light curing resins UDMA, finite elements analysis, fatigue
