Effect of microwave treatments on dimensional accuracy of maxillary acrylic resin denture base.
Microwave energy has been used as an alternative method for disinfection and sterilization of dental prostheses. This study evaluated the influence of microwave treatment on dimensional accuracy along the posterior palatal border of maxillary acrylic resin denture bases processed by water-bath curing. Thirty maxillary acrylic bases (3-mm-thick) were made on cast models with Clássico acrylic res...
متن کاملBasic studies on visible light-cured resin as a denture base. Part 17. Transverse and tensile strengths of repaired denture base resin using a trial repair resin.
Trial production of a visible light-cured repair resin (powder/liquid type, TPL) as a denture base resin was carried out using cyclophosphazene monomer, and then the transverse and tensile strengths of the repaired specimens were examined. As a control, Triad Gel (TRI) was used. In the transverse strength test, TPL showed values of 507-470 kgf/cm2, which were about double those of TRI. As for t...
متن کاملDimensional accuracy of acrylic resin maxillary denture base polymerized by a new injection pressing method.
The purpose of this study was to confirm the dimensional accuracy of a newly developed injection pressing method for resin polymerization by making use of the internal electric resistance of resin to determine the optimal timing for resin injection. A new injection pressing polymerization pot with a built-in system to measure the internal electric resistance of resin was used for resin polymeri...
متن کاملEffect of packing types on the dimensional accuracy of denture base resin cured by the conventional cycle in relation to post-pressing times.
This study investigated the dimensional stability of denture bases influenced by packing methods, in relation to post-pressing times, in the Clássico acrylic resin which was prepared according to manufacturer recommendations. Forty maxillary wax bases were made and randomly assigned into 2 groups of 20 specimens each according to the conventional and RS system packing methods. In each method, t...
متن کاملBonding of Acrylic Resin Teeth with Denture Base Resin
The debonding of acrylic resin teeth with the denture base resin has been related to several different factors of which contamination of the bonding surfaces with wax has been suggested as the major cause. The purpose of this study was to determine the efficient method of wax removal from denture teeth using hot water at different temperatures ranges. Acrylic rods were used as tooth analogues a...
