Wetting characteristics of denture lining materials indicate the degree of salivary lubricating effect, which promotes denture retention and patient comfort. This in vitro study investigated the wettability of ten commercially available visible light-cured denture lining materials.
Ten soft and hard visible light-curing materials, one autopolymerized hard lining material, and one autopolymerized denture base material were evaluated for wettability. Wettability was estimated by measuring the equilibrium and hysteresis contact angles using the dynamic contact angle analysis, or Wilhelmy, technique.
The equilibrium contact angle ranged from 59.9 to 77.3 degrees, and contact angle hysteresis ranged from 14.7 to 30.6 degrees.
Visible light-curing lining materials exhibit wetting properties similar to the conventional hard lining and denture base materials.
义齿衬里材料的湿润特性表明唾液润滑作用的程度,这有助于义齿固位和患者舒适度。本体外研究调查了十种市售可见光固化义齿衬里材料的润湿性。
对十种软硬可见光固化材料、一种自凝硬衬材料和一种自凝义齿基托材料的润湿性进行评估。使用动态接触角分析(即Wilhelmy技术)测量平衡接触角和滞后接触角来估计润湿性。
平衡接触角范围为59.9至77.3度,接触角滞后范围为14.7至30.6度。
可见光固化衬里材料表现出与传统硬衬里和义齿基托材料相似的湿润特性。
