“…In the present study, we investigated the clinical application of thermoplastic resins with emphasis on the esthetic aspects relative to conventional denture resins. Black tea, green tea and red wine were considered as soaking solutions, but coffee and curry were selected because of their stainability and amount of consumption by the public [28][29][30][31][32][33][34][35] . L*, a*, and b* indicate lightness, red-green, and yellow-blue, respectively.…”

Characteristics of denture thermoplastic resins for non-metal clasp dentures

Six thermoplastic resins and conventional acrylic resin were examined to characterize their mechanical and physical properties, water sorption, solubility, flexural strength, modulus of elasticity, tensile strength and color stability. Thermoplastic resins for nonmetal clasp dentures exhibiting low water sorption and solubility offer hygienic advantages. Since they have a low modulus of elasticity and are easily manipulated, these materials make it possible for larger undercuts to be used for retention compared to acrylic resin. Not all of the thermoplastic resins tested fractured after the bending test in contrast to the conventional denture base resin, which fractured when tested beyond its proportional limit. It was also found that clinically noticeable staining may occur on the polyamide resins and polyethylene terephtalate resins.

“…An attempt to improve the aesthetic effect by the reduction of RCA ends up with weakening of the retention force of RPD 15 . Retentive clasp arms of RPD are one of the factors that dictate the durability and function benefits of dentures 16 . It has been found that the durability of RCA depends on the material used as well as its design 17,18 .…”

The BIOS concept should be used only for RCAs made of CoCrMo alloy and different wax profiles should be used for fabricating clasps of other investigated materials. The contribution of this study may be the improve ment of present systems for defining the clasps shapes made from (CoCrMo alloys. The more significant application is the possibility of creating new concepts in defining shapes of RCA made from CPTi and polyacetale.

“…The photogrammetric procedure for measuring the two‐dimensional damage area was based on high‐resolution digital images with a standard reference scale for image calibration and open‐source software for image processing. Similar procedures have been successfully applied in the assessment of dental prostheses with curved surfaces and eroded metallurgical samples 28, 29. The defined measurement criteria for the surface features and damage modes (Table III) aided repeatability among different observers, which is especially important for uniform detection and identification of damage boundaries during image segmentation.…”

Repeatable procedure for evaluating taper damage on femoral stems with modular necks

Understanding the performance of dual-taper modular femoral stems necessitates detailed quantitative assessment. This study reports a repeatable procedure to identify and measure damage on modular taper surfaces and determines whether damage area is a useful parameter for discerning modular femoral stem performance during in vitro corrosion and endurance tests. Twenty-four dual-taper modular necks representing a range of functional conditions were evaluated, including 15 necks previously subjected to in vitro testing and 9 necks explanted during revision hip arthroplasty. Objective identification of six surface features, including four unique damage modes, was accomplished using defined criteria combined with a standardized photogrammetric method for accurate and repeatable measurement of damage area and location. Damage area was a useful parameter for discerning the performance of modular femoral stems subjected to different in vitro tests. The sum of burnished smooth and textured damage areas was linearly correlated with the magnitude of material removed (weight loss) during in vitro testing, predicting ∼ 1.0 mg additional weight loss for every 10% increase in those combined damage areas. Modular necks tested with higher load magnitudes and those coupled with larger, stiffer femoral stems were readily distinguished and showed significantly larger areas of burnished smooth and textured damage.
