Final answer:
A delay could result in decreased flow of the casting material, affecting the fit of the dental restoration. It's important to handle restorative materials promptly and according to instructions to prevent issues.
Step-by-step explanation:
A delay between the final mix and the actual seating of the restoration could result in decreased flow of the casting material and the possibility of the casting not fitting completely. Dental materials like casting materials must be seated promptly after mixing to ensure adequate flow and adaptability to the prepared tooth structure. As the material begins to set, its flow characteristics diminish, which may lead to problems with the fit of the dental restoration. It is crucial that restorative materials are handled according to the manufacturer's instructions to prevent any issues that may compromise the long-term success of the restoration and patient's oral health.
