简要总结

Resilient liners were introduced in the1950s and have been used since then as a gold standard material to increase the tolerance, retention and comfort of complete dentures. Due to drawbacks of conventional resilient liners, their longevity is questionable and they require replacement which is time consuming and costly for the dentist and patient respectively. Versacryl is a biocompatible intraoral thermo-elastic material. So versatile, it can be used to improve esthetics, retention and comfort for the patient. It softens with heat and when it is inserted to patient's mouth, it cools to body temperature providing desired rigidity. This process can be repeated many times to ensuring the comfort for the patient. Versacryl has a reported predictable long term performance, durable bonding to acrylic denture bases, high fatigue endurance, excellent wear characteristics and solvent resistance with almost no free monomer in the processed material .

The investigators' trial is done in order to improve the longevity and oral health related quality of life of soft liners in comparison to silicone-based soft liners.

研究组 & 干预措施

Versacyl soft liner

Experimental

Versacryl soft liner are flexible biocompatible materials with a reported predictable long term performance, durable bonding to acrylic denture bases, high fatigue endurance, excellent wear characteristics and solvent resistance with almost no free monomer in the processed material

干预措施: Versacryl soft liner (Other)

Silicone-based soft liner

Active Comparator

Resilient liners were introduced in the1950s and have been used since then as a gold standard material to increase the tolerance, retention and comfort of complete dentures. Resilient liners also known as 'soft liners' can be classified as temporary or permanent, cold-cured or heat-cured.Resilient liners can be divided into two main types: plasticized acrylic resins and silicone elastomers.

干预措施: Silicone-based soft liner (Other)
