Materials and Methods: Eighty cylindrical shape specimens were fabricated from self-polymerized provisional Poly methyl methacrylate PMMA and they were randomly divided into eight groups. Poly methyl methacrylate PMMA was mixed and bonded onto the specimens as a positive control group. Resin composite was bonded to MMA-wetted surface without bonding agent as a negative control group. Shear bond strength testing was performed using a universal testing machine. Various shades of 0. Color differences between resin composite and — layered provisional Poly methyl methacrylate PMMA were measured using Spectrophotometer. The highest shear bond strength was achieved with the application of Scothbond Universal Adhesive regardless of MMA wetting. Article Information. Provisional Restorations
The therapeutic use of thermoplastic materials has increased drastically in the late decade. This new procedure, during which a fully polymerized basic material is softened by heat without chemical changes read article injected afterwards, has opened up a new chapter in making dentures. The excellent tissue-friendly and mechanical characteristics of these basic materials can only be made to last by an exactly executed and reproducible technology. Current dental applications of thermoplastic materials include: preformed partial denture clasp, flexible Provisional Restorations born partial denture framework, single cast partial dentures, temporary crowns and bridges, provisional crowns and bridges, occlusal appliances, implant abutments, orthodontic and sleep apnea appliances, many of which have Provisional Restorations described previously.
However, with the development of new elastomers and copolymer alloys, there are certain to be many new clinical applications for thermoplastic resins in dentistry. The differences between them are the materials used to support the denture teeth Provisional Restorations retain the RPD in the mouth. The application of nylon-like materials to the fabrication of dental appliances.
This material generally replaces the metal, and the pink acrylic denture material used to build the framework for standard removable partial dentures. Thermoplastic materials for dental prostheses, Valplast Valplast Int. Both materials were similar grades of Polyamides nylon plastics.

Since their introduction, there has been a continued interest in thermoplastic dental materials. Rapid Injection Systems currently known as The Flexite Company — USAoriginated inintroduced Provisoonal first Provisional Restorations thermoplastic which was a flouropolymer a Teflon-type of plastic. While the material was not strong enough to allow for conventional tooth born rest seat, the flexibility added to patient comfort in wearing the appliances. Flexite also was early into the dental market with flexible thermoplastic acrylic hybrid resin for removable appliances. Acetal Provisional Restorations first proposed as an Provisional Restorations thermoplastic resin removable partial denture material in It was during this period that Rapid Injection Systems developed the first tooth-colored clasps with a thermoplastic fluoropolymer.
The clasps were flexible, did not need periodic adjustment to keep them tight, and the tooth colored esthetics were appreciated by the patients. Pressing Dental followed in the early s with an Acetal resin, marketed in the U. InThe Flexite Company, developed and patented the first pre-formed tooth-color clasps known as Clasp-Eze. This product, made of a nylon material, is available in pink and clear color shades and currently sold worldwide. The FRS system utilizes a flexible tissue colored thermoplastic resin for flexible partial dentures. Currently Cosmetic Dental Materials, has introduced Aesthetic PerfectionT patent pendinga new line of thermoplastic Acetal, Acrylic, and Polycarbonate materials that Provjsional be used in most thermoplastic presses.
These materials offer excellent esthetics combined with favorable physical properties and easy processing characteristics. Thermoplastic resins tend to have predictable long-term performance.
They are stable and resist thermal polymer unzipping. They also exhibit high creep resistance and high fatigue endurance as well as excellent wear characteristics and solvent resistance. Thermoplastic resins Provisional Restorations have very little or almost no free monomer in the material. A significant percentage of the population is allergic to free monomer and these materials offer a new safe treatment alternative for these individuals. In addition, thermoplastic materials have almost no porosity, which reduces biologic material build up, odors, and stains and exhibit higher dimension and color stability. All of Provisional Restorations factors become important when producing long-term provisional prostheses during implant or complex restorative Provisional Restorations, or when used for permanent removable appliances.
Typically, the thermoplastic resins are more flexible and stronger than their traditional counterparts are. Elastomeric resins can be added to the resin polymer formulas to create greater flexibility, which reduces fracturing. Thermoplastic resins can also be reinforced with glass filler or fibers to further enhance their physical properties.

At the same time, these restorations can be relined and repaired, by Provisional Restorations the restoration. The thermoplastic resins can produce single cast or pressed restorations that are strong, lightweight, flexible appliances in tissue or tooth color matched materials that never need adjusting.
These restorations display excellent esthetics and provide long-term comfortable use for the patient. This provides excellent alternative cosmetic restorations for esthetic-conscious patients. Thermoplastic resins are used for a broad variety of applications from removable flexible partial dentures, preformed partial rPovisional clasps, fiber reinforced fixed partial dentures temporary Resstorations and bridges, provisional crowns and bridges, obturators and speech therapy appliances, orthodontic retainers and brackets, impression tray and Provisional Restorations molding materials, occlusal splints, sleep apnea appliances, and implant abutments.
Acetal resin is very strong, resists wear and fracturing, and is quite flexible. These characteristics make it an ideal material for pre-formed clasps for partial dentures, single pressed unilateral partial dentures, partial denture frameworks, Provisional Restorations more info, occlusal splints, and even implant abutments.]
