“…Fiberle güçlendirilmiş kompozit akrilik rezinlerin çekme ve basma kuvvetlerine karşı dayanıklılığı fiberle güçlendi-rilmeyen kompozit akrilik rezinlerden fazladır. [32][33][34] Ayrıca cam fiberlerin, rezin kompozite ilave edilmeden önce silan kaplama ajanlarıyla silanize edilmeleri adezyonu arttırır. [35][36][37] İstatiksel analizlere göre farklı silan uygulamaları adezyonda önemli farklılıklara neden olabilmektedir.…”

//dx.doi.org/10.4047/jkap.2013.51.4.284 Purpose: This study compared fracture strength and fracture modes between metal wire reinforcement and glass fiber reinforcement in repaired maxillary complete denture. Materials and methods: In this study, fracture was reproduced on center of maxillary complete dentures and the denture was repaired with auto-polymerizing resin. The experimental groups (n = 10) were subjected to the following condition: without reinforcing material (control group), reinforcing with metal wire (W group), reinforcing with glass fiber pre-impregnated with light-curing resin (SES MESH, INNO Dental Co., Yeoncheon, Korea, G group). The fracture strength and fracture modes of a maxillary complete denture were tested using Instron test machine (Instron Co., Canton, MA, USA) at a 5.0 mm/min crosshead speed. The flexure load was applied to center of denture with a 20 mm diameter ball attachment. When fracture occurred, the fracture mode was classified based on fracture lines. The Kruskal-wallis test and the Mann-whitney U test were performed to identify statistical differences at α =.05. Results: W group showed the highest value of fracture strength, there was no significant difference (P>.05) between control group and G group. Control group and W group showed anteroposterior fracture mainly, group W showed adhesive fracture of denture base and reinforcing material. Conclusion: In limitation of this study, the glass fiber did not improve the fracture strength of repaired maxillary complete denture, and adhesive failure was occurred along the lines of glass fiber.

“…However, an evaluation of the effect of long-term water immersion on the strengths using a denture base -shaped specimen is beneficial for clinical purposes. In some studies [10][11][12][13] strictly related to the flexural strengths of denture base-shaped specimens in vitro, the investigators estimated the reinforcement location in maxillary acrylic resin complete dentures. However, there is insufficient information to evaluate the effect of long-term water immersion on the strengths of denture base-shaped specimens.…”

“…Furthermore, denture base plastics typically exhibit considerable plastic deformation before fracture. The plastic deformation beyond its proportional limit permanently alters the dimensions of a denture and is not clinically acceptable; therefore, some studies 6,7,[11][12][13][14][15][16] evaluated the resistance of denture polymers to plastic deformation under a flexural load.…”

Fracture resistance of maxillary complete dentures subjected to long-term water immersionObjective: This study investigated the fracture resistance of maxillary acrylic resin complete dentures subjected to long-term water immersion. Materials and Methods: Maxillary acrylic resin complete dentures were fabricated from five denture base resins. Half of the dentures were stored in water for 50 h, and the other half were kept in water for 180 days before testing. Ten specimens were fabricated per group. The flexural load at the proportional limit (FL-PL) of the dentures was tested. Results: A two-way ANOVA revealed a significant difference in FL-PL because of the denture base material variable. There were no significant differences in FL-PL because of the effect of water immersion and the interaction between the effect of water immersion and the denture base material. The FL-PLs of the dentures fabricated with the two conventional heat-processed resins, the pour-type autopolymerizing resin and the microwave energy-processed resin were not significantly different from each other; they were significantly higher than the light-activated resin in regard to their FL-PL. Conclusion: The FL-PLs of the maxillary acrylic resin complete dentures did not change after long-tern water immersion, and the FL-PL of the denture fabricated from the light-activated resin was lower than those of the other materials.
