| 520 | _aFabrication of provisional restorations is an important step toward achieving a successful prosthetic treatment. A provisional restoration is used to protect and sedate the pulp of prepared abutments, promote periodontal healing and health, replace missing teeth, prevent migration of abutments and provide esthetics. Provisional restorations also assist in the development of occlusal schemes and evaluation of phonetics. In addition, they protect abutments from microleakage and chemical injuries and stabilize compromised teeth. This study was designed to investigate, in vitro, the effect of long term storage and thermo-cycling on the vertical marginal gap distance and microleakage of machinable acrylic blocks for provisional restoration (VITA CAD-Temp) in comparison to self-cured bis-acrylic composite provisional restoration material (Protemp 4). A total of twenty four provisional crowns were constructed and divided according to provisional materials into two main groups: Group A: 12 Provisional crowns were constructed from machinable acrylic blocks (VITA CAD-Temp). Group B:12 Provisional crowns were constructed from self-cured bis-acrylic composite (Protemp 4 ). 116 | ||
