Dentures are commonly fabricated using a metallic or plastic base, with the teeth either made from acrylic or porcelain. Some dentures, particularly flexible dentures, are constructed using a nylon-derived base material. Other materials, such as denture adhesives, provides support and secure the dentures in place, notes iDentalHub.
One primary restorative dental treatment option for the replacement of missing teeth is to wear dentures, which are customized dental prostheses designed to fit the individualized needs of patients. Dentures are mainly categorized into four types: partial, complete, immediate and over-dentures. The materials used for each type may vary.
Complete dentures are generally made from an acrylic resin, particularly polymethyl methacrylate. This type of material is most suitable for immediate dentures for the instant replacement of teeth that require removal.
Partial dentures fashioned from acrylic are low cost and simple to create. However, an ill-fitting design of these prostheses coupled with improper oral care may lead to periodontal disease. Another drawback in using acrylic removable plates is the lack of tensile strength of polymethyl methacrylate, which can result in fractured dentures, explains the United States National Library of Medicine.
Partial dentures made from a metallic base are more wear resistant compared to plastic incomplete dentures. This type of base material is also more manageable and hygienic for users, although the costs are significantly higher than acrylic-based partial dentures, notes DentalCareMatters.
