When making adjustments to an interim restoration, which aspect is primarily considered?

The aspect primarily considered when making adjustments to an interim restoration is maximum intercuspation. Maximum intercuspation refers to the occlusal relationship that occurs when the cusps of the teeth interdigitate maximally, providing the most stable occlusal contact. This position is crucial for ensuring that the patient can function comfortably and effectively with the interim restoration during the healing or transitional phase.

Adjustments made to achieve or maintain maximum intercuspation focus on optimizing occlusal contacts to minimize discomfort or excessive wear on the restoration and the opposing teeth. It ensures that forces are appropriately distributed across the dental arch, which can help in preventing issues such as jaw pain or uneven wear.

In contrast, centric occlusion is a broader term that refers to the occlusion present when the jaw is in a closed position, while centric relation describes the maxillomandibular relationship when the jaw is in the most retruded position, independent of tooth contact. The incisal edge position is important in certain restorations, particularly anterior teeth, but it is not the primary focus when adjusting interim restorations. The emphasis on maximum intercuspation provides the best immediate reference for achieving proper occlusal relationships in temporary restorations, enhancing comfort and functionality.
