Heat cure acrylic denture base material, thermosense denture base material, hardness, impact strength, transverse strengthAbstract
Background: Thermosense material is the innovative virtually unbreakable, new
monomer free rigid denture base material easy and quick to polish and available
in 10 colors, suitable to patients unable to accept denture made from materials
that could result in allergic reactions or other sensitivity problems. This type is
suitable for full and partial denture and can be used for rebase and reline jobs.
Also suitable for overdenture on implant and for repair.
Material and methods: sixty samples were prepared and divided in to two main
groups according to the type of material that used (thermosense denture base
material and heat cure acrylic denture base material). Each main group were
subdivided in to three subgroups according to the type of test that has used
(Hardness, impact strength, and transverse strength). Data were analyzed by oneway
analysis of t-test.
Results: for this study the result for three tests; hardness, transverse strength and
impact strength show high significant difference.
conclusion: This study showed Thermosense denture base material had higher impact
strength than Heat cure acrylic denture base material but this material had higher
transverse strength and hardness than Thermosense denture base material.
