“…The examinations were carried out in terms of the prosthetic basis conditions and the perception of pain [19]. The invaluable role of soft relining materials has also been demonstrated not only during the prosthetic rehabilitation of patients with difficult conditions of the prosthetic base, but also in the relief of alveolar processes after resection and implantation procedures, with clefts of the palate, during the treatment of inflammatory-fibrous hyperplasia, in patients suffering from scleroderma or in elderly people to accelerate the adaptation to new prostheses [17][18][19][20][21][22][23]. Currently, the most commonly used soft materials for long-term relining can be divided into two main groups due to their chemical composition: silicone and acrylic [16].…”

The main functional feature of elastomeric soft linings materials is the ability to discharge loads in the tissues of the mucosa. As a result, there are fewer injuries to the mucosa and chewing ability increases. In addition, these prostheses are more comfortable in the patient’s opinion. To obtain the equal distribution of forces on the muco-bone basis and to reduce the traumatizing effect of the denture plate for patients using full dentures, soft lining materials can be used. Aim of the study: the aim of the work was a comparative laboratory study of ten materials used for soft lining of acrylic complete dentures. Methodology: Materials based on acrylates (Vertex Soft, Villacryl Soft, Flexacryl Soft) and on silicones (Sofreliner Tough Medium, Sofreliner Tough Medium, Ufi Gel SC, GC Reline Soft, Elite Soft Relining, Molloplast) were compared. Laboratory tests include tests of changes in Shore’a A hardness of soft lining material. The tests were conducted taking into account 90 day term aging in the distilled water environment based on the methodology presented in the European Standard ISO 10139-2. Results: For most silicone materials, only small changes in hardness were found in the range of 0.7 (Ufi Gel SC) to 3.3 (Sofreliner Tough Medium) on the Shore A scale. The exception was GC Reline Soft, for which a marked increase in hardness was noted. All materials based on acrylates were characterized by successive increase in hardness over time. However, in the case of the Vertex Soft material, the increase in hardness was relatively small (5.5 ShA).
