Study Notes
Purpose and Requirements of Provisional Restorations
- The primary purpose of provisional restorations is to maintain aesthetics, allow for normal oral function, and prevent tooth migration or supra-eruption.
- Biologic requirements of provisional restorations include maintaining pulp vitality, protecting soft tissues, and preventing caries and plaque accumulation.
- Provisional restorations help prevent tooth sensitivity,牙migmatism, and supra-eruption of adjacent teeth.
Mechanical and Esthetic Requirements
- Esthetic requirement of provisional restorations is to replicate the natural tooth form and color.
- Mechanical requirement of provisional restorations is to resist chewing forces and maintain marginal integrity.
Fabrication and Materials
- Slightly enlarging the connector area in a fixed partial denture allows for easier fabrication and maintenance of the provisional restoration.
- The type of provisional restoration is selected based on factors such as the patient's oral habits, span of the edentulous area, and material properties.
- A factor NOT considered when selecting the type of provisional restoration is the dentist's preference.
- Custom-made provisional restorations are fabricated using the indirect fabrication method.
- Resin-based materials exhibit increased shrinkage and heat generation in provisional restorations.
- The primary purpose of resin-based provisional restorations is to provide a temporary aesthetic solution.
- Metal-based provisional restorations are commonly fabricated using acrylic or composite resins, but NOT ceramic materials.
- An impression type used for fabricating custom-made provisional restorations is a master impression.
- Acrylic resin exhibits increased strength, hardness, and marginal fit in provisional restorations.
