Abstract
:1. Introduction
2. Materials and Methods
2.1. Laboratory Materials and Methods
- Sofreliner Tough M (Tokuyama, Taitou-ku Tokyo, Japan) is a soft material based on additional silicone. Binds AT room temperature. It is used in the indirect and direct method.
- Sofreliner Tough S (Tokuyama, Taitou-ku Tokyo, Japan) is an A-silicone material. The product is qualified as a super soft material. The Sofreliner set includes pastes applied using an automix cartridge system and a primer used to bond with acrylic surfaces. The material binds at room temperature both in the direct and indirect method.
- Mollosil Plus (Detax, Ettlingen, Germany) is a Type A silicone material that polymerizes at low temperature. It is available in automatic mixing containers when applied on a denture by direct and indirect methods.
- Ufi Gel SC (VOCO, Cuxhaven, Germany) is a soft A-silicone material. The material is cured at room temperature, which makes Ufi Gel SC simple and quick to use. Relining can be done directly in the patient’s mouth and in the laboratory. The kit includes an automix cartridge system.
- GC Reline Soft (GC, Tokyo, Japan) is a soft A-silicone-based relining material for long-term indirect and direct relining at room temperature. The material is available in automatic mixing cartridges.
- Elite Soft Relining (Zhermack, Badia Polesine, Italy) is an additional silicone material for use in the dental office using the direct method and in the technical laboratory using the indirect method. Cross-linking of the material occurs at room temperature [26].
- Molloplast B (Detax, Ettlingen, Germany) is a one-component silicone used in the indirect method. The material polymerizes at high temperature in a water bath or in the microwave.
- Vertex Soft (Vertex Dental, Soesterberg, The Netherlands) is a denture polymer that polymerizes under the influence of heat. Polymerization takes place by heating the material for 3 h at 70 °C, and then for 30 min at 100 °C.
- Villacryl Soft (Zhermack, Badia Polesine, Italy) is an acrylic material that polymerizes at a high temperature—at 65 degrees under a pressure of 2.2 Bar for 30 min.
- Flexacryl Soft (Lang Dental, Wheeling, IL, USA) is a flexible acrylic material used in the indirect method for relining denture plates.
