Acrylic resin is the most commonly used denture base material. However, it has a shortage of being easily broken. One way to resolve this problem is by adding polyethylene (PE) or glass fibers. The purpose of this research is to compare the transversal strength of PE and glass fibers from denture plate acrylic resin repair material. The experiment involved 32 plates of heat cure acrylic with the dimensions of 65 mm x 10 mm x 2.5 mm. The speciments were prepared to create a 3 mm gap and 45° bevel. Subjects were divided into 2 groups, each group containing 16 plates. Group I was reinforced with PE fiber and Group II was reinforced with glass fiber. All plates were soaked in distillation water for one day at 37 °C. Plates were tested for transverse strength with universal testing machine and all data were analyzed with independent t-tes at 95% confidence level. Macro photo analysis was used to observed the bond failure on fiber and resin. The mean of transverse strength (MPa) denture plate acrylic resin repair material reinforced with PE fiber was (67.38 ± 4.31) MPa, while glass fiber was (93.61 ± 6.14) MPa. Independent t-tes showed that type of fiber had a significant effect (p<0.05). Thus, it is possible to conclude that addition of glass fibers in denture plate acrylic resin repair material increased the transverse strength and made it stronger than those added with PE fibers.

The effect of e-glass fiber volumetric on transverse strength of an acrylic resin denture plate repair. Acrylic resin is the most commonly material for the denture base. A disadvantage of acrylic resin is that it is easily to be cracked. One of the ways to resolve this problem is by adding the E-glass fibers. The purpose of this research was to find out the effect of volumetric E-glass fiber on transverse strength of an acrylic resin denture plate repair. The experiment involved thirty plates of heat cured acrylic with the dimensions of 65 × 10 × 2.5 mm. The specimens were prepared to create a 3-mm gap and 45° bevel. Subjects were divided in to 3 groups, each of which contained 10. Group I (control) was with no fiber reinforcement, group II was reinforced with 3.7vol % E-glass fiber, and group III was reinforced with 7.4 volume % E-glass fiber. All plates were soaked in distillation water for one day at 37 °C. Plates were tested for transverse strength with Universal Testing Machine and all data obtained was analyzed with one way anova at 95% confidence level (α= 0.05). The significant difference was found between the transversal force of acrylic resin plat enforced with fiber and other group without being reinforced with fibers (p<0.05). Group reinforced with 7.4 vol % E-glass fibers showed a significant difference (higher) than the group reinforced with 3.7 volume % fibers. The addition of E-glass fibers in an acrylic resin plate repair material increased the transverse strength. The increase in volumetric fibers might improve the transverse strength of an acrylic resin plate repair material.ABSTRAKResin akrilik merupakan bahan yang sering digunakan dalam pembuatan basis gigi tiruan.

All plates were soaked in distilled water for one day at 37° C temperature. The plates were tested for transverse strength with Universal Testing Machine and all data obtained were analyzed with two way ANOVA at 95% confidence level. The mean of transverse strength (MPa) of the acrylic resin plate repair reinforced with fiber: 3.7% v/v PE fiber was (67.77±3.34); 7.4% v/v PE fiber (80.37±8.42); 3.7% v/v E-glass fiber (96.72±5.43); 7.4% v/v E-glass fiber (109.44±4.98); while the transverse strength of the acrylic resin plate with no fiber reinforced was 56.27±4.7 MPa. Two way ANOVA analysis shows that type and volumetric fiber had significant effect (p<0.05), while the interaction between type and volumetric fiber had no significant effect (p>0.05). Tukey post hoc test shows significant difference (p<0.05) for all groups. The addition of E-glass fibers in the acrylic resin plate repaired increased the transverse strength higher than that with PE fibers. The increase in volumetric fibers might improve the transverse strength of the acrylic resin plate repaired.

Heat-polymerized  acrylic  resins  is  the  most  used  denture  base  material  in  prosthodontics.  One  of  mechanical properties of acrylic resins is transverse strength. It represents the masticatory pressure that is applied to denture base. Black tea is the second largest consumed beverage in the world. The aim of this study was to investigate the effect of black tea beverage on transverse strength of heat-polymerized acrylic resins. A total of 24 heat-polymerized acrylic resin plates (65×10×2,5 mm) were immersed in black tea beverage for 1, 4, and 20 days as treatment group and in aquadest for 1, 4, and 20 days as control group. The transverse strength of  acrylic samples were measured by three–point bending test by universal testing machine. Data were statistically analyzed using Independent t test. The transverse strength values of acrylic resin immersed in black tea beverage had no significant differences to the transverse strength values of acrylic resin immersed in aquadest with similar immersion time (p>0,05). There was no effect of black tea beverage on transverse strength of heat-polymerized acrylic resins. Immersion time decrease the transverse strength of heat-polymerized acrylic resins due to water sorption. Keywords: Heat-polymerized acrylic resins, black tea, transverse strength

Background: In acrylic removable dentures, brokenness often occurs in the midline region of the maxilla. Resistance to fracture depends on the physical properties of the material namely the transverse strength. This can be prevented by the addition of glass fibers. Tea is consumed by many people, acrylic resin dipped in steeping tea will reduce the strength of acrylic resin. How the physical properties of acrylic resin are modified by the addition of glass fiber effect when immersed in a tea solution. Purpose: This study was to determine the strength of transverse acrylic resin with the addition of glass fibers soaked in tea. Method: Rectangular acrylic resin with a size of 10 x 65 x 2.5 mm. The number of samples is 24. divided into 4 groups. namely 2 groups without glass fiber and 2 groups with glass fiber. The sample is measured by transverse strength using an autograph (Shimadzu) tool, then data is analyzed using ANOVA. Result: Acrylic resin without glass fiber immersed in tea solution decreases its transverse strength. while the acrylic resin was given glass fiber the strength value of the transversion does not differ significantly either soaked or not. Conclusion: Acrylic resin which is given glass fiber and soaked in tea does not reduce the strength of the transversion. This is due to the glass fiber filling the cavity in the acrylic resin.

Objective.The aim of this study was to evaluate the effect of incorporation of glass fiber, zirconia, and nano-zirconia on the transverse strength of repaired denture base.Materials and Methods.Eighty specimens of heat polymerized acrylic resin were prepared and randomly divided into eight groups (n=10): one intact group (control) and seven repaired groups. One group was repaired with autopolymerized resin while the other six groups were repaired using autopolymerized resin reinforced with 2 wt% or 5 wt% glass fiber, zirconia, or nano-zirconia particles. A three-point bending test was used to measure the transverse strength. The results were analyzed using SPSS and repeated measure ANOVA and post hoc least significance (LSD) test (P≤0.05).Results.Among repaired groups it was found that autopolymerized resin reinforced with 2 or 5 wt% nano-zirconia showed the highest transverse strength (P≤0.05). Repairs with autopolymerized acrylic resin reinforced with 5 wt% zirconia showed the lowest transverse strength value. There was no significant difference between the groups repaired with repair resin without reinforcement, 2 wt% zirconia, and glass fiber reinforced resin.Conclusion.Reinforcing of repair material with nano-zirconia may significantly improve the transverse strength of some fractured denture base polymers.
