Provisional Restorations Quiz

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.
