“…In the present study, in accordance with Usumez et al4 iBMA groups showed the highest bond strength and adhesive failure only. This result was not in accordance with those of Kulak-Ozkan et al7 and Hatamleh et al19 These findings are understandable and can be explained in that the molecular binding of the resilient liner was improved. According to the results of the present study, the iBMA immersion of soft liners significantly increased the tensile strength of the specimens, while all the specimens revealed adhesive failure.…”

“…Moreover, according to Kulak-Ozkan et al7 34 showed adhesive failures, 15 showed cohesive failures, and 23 showed mixed failures out of 72 specimens. In addition, Hatamleh et al19 reported that all specimens exhibited cohesive failure only because of net fibers. In the present study, in accordance with Usumez et al4 iBMA groups showed the highest bond strength and adhesive failure only.…”

“…In the dental literature, the difficulty of obtaining a reliable bond between soft relining materials and PMMA denture base polymers has often been discussed 17. Several studies have been conducted to increase bond strength between liners and acrylics by improving roughness at the acrylic interface using lasers,1,4,9,14 alumina abrading,4,9,10,15,18 chemical etching or primers, acrylic burs, and net woven glass fiber 19…”

PURPOSEThe purpose of this study was to investigate the bonding properties of denture bases to silicone-based soft denture liners immersed in isobutyl methacrylate (iBMA) and 2-hydroxyethyl methacrylate (HEMA) for various lengths of time.MATERIALS AND METHODSPolymethyl methacrylate (PMMA) test specimens were fabricated (75 mm in length, 12 mm in diameter at the thickest section, and 7 mm at the thinnest section) and then randomly assigned to five groups (n=15); untreated (Group 1), resilient liner immersed in iBMA for 1 minute (Group 2), resilient liner immersed in iBMA for 3 minutes (Group 3), resilient liner immersed in HEMA for 1 minute (Group 4), and resilient liner immersed in HEMA for 3 minutes (Group 5). The resilient liner specimens were processed between 2 PMMA blocks. Bonding strength of the liners to PMMA was compared by tensile test with a universal testing machine at a crosshead speed of 5 mm/min. Data were evaluated by 1-way ANOVA and post hoc Tukey-Kramer multiple comparisons tests (α=0.05).RESULTSThe highest mean value of force was observed in Group 3 specimens. The differences between groups were statistically significant (P<.05), except between Group 1 and Group 4 (P=.063).CONCLUSIONImmersion of silicone-based soft denture liners in iBMA for 3 minutes doubled the tensile bond strength between the silicone soft liner and PMMA denture base materials compared to the control group.

Ö ÖZ ZE ET T A Am ma aç ç: : Farklı içeceklerin, silikon esaslı yumuşak astar materyalinin bağlanma dayanımı üze-rine etkilerini değerlendirmektir. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Yüz yirmi adet ısı ile polimerize olan polimetilmetakrilat (PMMA) esaslı çekme gerilimi test örnekleri (75x12x7 mm), üretici firmaların talimatlarına göre hazırlandı. Örneklerin yarısına yumuşak astar materyali (Permaflex), kalan yarısına ise izobütilmetakrilat (iBMA) emdirilmiş yumuşak astar materyali uygulandı ve sonrasında su, kola, soda ve portakal suyu içerisinde 37 o C'deki su banyosunda bir ay süreyle bekletildi. Daha sonra örneklere üniversal test cihazında çekme gerilimi testleri uygulandı. Ayrıca, kopma tipleri sonuçları stereomikroskop altında değerlendirilerek kaydedildi. Verilerin değerlendiril-mesinde one-way ANOVA ve Tukey çoklu mukayese testleri (p=0,05) kullanıldı. B Bu ul lg gu ul la ar r: : Permaflex (Perma) grubunda ortamlar arasında istatistiksel olarak anlamlı fark görülmedi (p>0,05). |Perma+iBMA| grubunda ise ortamlar arasında istatistiksel olarak anlamlı fark görüldü (p<0,05). En yüksek bağlanmanın su içerisinde bekletilen Perma+iBMA grubunda olduğu belirlendi (2,00±0,07 MPa). Perma+iBMA grubu bağlanma kuvvetinin Perma grubuna göre, su ve soda ortamlarında daha yüksek olduğu görüldü (p<0,05). S So on nu uç ç: : iBMA'ın, yumuşak astar materyaline emdirilmesi, akrilikle yumuşak astar arasındaki bağlanma dayanımı üzerinde pozitif etki gösterdi. Ancak, Perma+iBMA astar materyalinin tüm ortamlarda bağlanma direnci suya göre azalırken, Perma grubunda önemli bir değişiklik görülmedi.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Protez astarları; polimetil metakrilat; poli(izobütil metakrilat) A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The purpose of this study was to investigate the effect of different kind of drinks on tensile bond strength of soft denture liner material.

“…However, some patients are not able to withstand the forces transmitted by denture bases because of sharp alveolar ridge, atrophied ridge, and thin atrophic mucosa. Resilient denture liners are used to cushion the inner surface of removable dentures, helping to evenly distribute mastication forces, preventing trauma of sensitive mucosa, enhancing denture retention by engaging undercuts [1,2]. The use of siliconebased resilient denture liner in mandibular complete dentures resulted in significant improvements in their satisfaction ratings compared with conventional heat-activated acrylic resin [3].…”

particles including electronically excited electrons, ionic and free radical species, and photons in the short-wave ultraviolet (UV) range [10]. Plasma treatment is a gentle method to change the characteristics of the topmost layer of polymers. Plasma irradiation does not cause environmental pollution and is a useful method to increase adhesive strength between heat-cured acrylic resin and self-curing acrylic resin [11]. Recent study indicated that plasma treatment appeared to increase the tensile-shear bond strength between post and composite [12]. The bond strength between silicone-based soft liner and fresh denture base has been investigated in previous studies [13,14]. However, there is no paper that discussed the adhesion between silicone-based soft liner and aged denture base, although the aged denture base is frequently used in clinical practice. In the present study, thermocycling (5-55°C) was used to simulate the aging process.The objective of this study was to evaluate the plasma treatment effect on the tensile bond strength between silicone-based soft liner and thermocycled denture base. The null hypothesis of the study was that the plasma treatment would improve the tensile bond strength between silicone-based soft liner and thermocycled denture base.

Abstract: Molloplast-B exhibited a stronger bond to StickTech Net fiber-reinforced surfaces when compared to smooth and rough acrylic interfaces after thermocycling. This may enhance prosthesis serviceability during clinical use.
