1.Aesthetics => Translucency of the material picks up underlying tissue tones, making it almost impossible to detect in the mouth. No clasping is visible on tooth surfaces (when used in manufacturing of clear clasps), improving aesthetics. No metal clasps are present.
2.Strength => Flexible denture material is so strong that it can be made very thin which makes it comfortable to wear and esthetically pleasing.
3.Accuracy => As the flexible dentures are fabricated using the injection molded technique, they exhibit better accuracy compared to conventional techniques.
4.Management of undercuts => Being flexible, the denture base adapts well in the undercut areas. The amount of adjustment required at time of denture insertion is greatly reduced. Also this reduces post insertion complaints of denture induced trauma (ulceration).
5.Bio compatibility => Complete bio-compatibility is achieved because the material is free of monomer and metal, these being the principle causes of allergic reactions in conventional denture materials.
6.Provisional dentures => Provisional dentures are advised by dentists during healing period. After surgical reconstruction of the edentulous maxilla either by alveolar augmentation or a distraction procedure and implant placement there is a need to accommodate the patient during the period between surgery and the fabrication of a definitive dental prosthesis. In this postoperative period during the consolidation phase of the reconstructed maxilla, a flexible denture offers an interim solution that allows the patient to resume daily activities. Dentures made of flexible materials prevent peak forces and, thereby, preserve more regenerated osseous tissue than hard acrylic resin dentures. Providing a flexible dental prosthesis during the consolidation phase of grafted bone and implants enables the patient to bridge the time needed for optimal osseo-integration of the dental implants and fabrication of a definitive prosthesis without jeopardizing the regenerated osseous tissue.
7.Better comfort of the patient => Flexible dentures form an excellent alternative to traditional hard fitting denture. Patients show excellent compliance as there is no metal display. Material being soft and strong can be made thinner and are light in weight compared to conventional dentures. This promotes better adaptation of the tongue and cheek to the denture base. Flexible dentures will not cause sore spots and have better comfort level which can be attribute to low modulus of elasticity. These dentures absorb small amounts of water to make the denture more soft tissue compatible.
8.The material has good flexibility like Titanium. Therefore, even if there is a little bit of bending, it comes back to the original shape and position.
9.In cases of undercut due to tilted teeth, flexibility of the material makes it possible to insert the prosthesis over the angulated teeth.
