What is the required distance between occlusal contact and enamel restoration junction?

The correct distance between the occlusal contact and the enamel restoration junction is recognized as 1 mm. This measurement is important because it ensures that there is adequate space for the restoration material while maintaining the integrity of the tooth structure. Having this distance helps in achieving a proper occlusal relationship, minimizes the risk of wear on the restoration, and allows for effective function of the occlusion.

Maintaining this 1 mm distance is essential for several reasons, including providing sufficient thickness of the restorative material for durability and resistance to fracture, as well as allowing for proper gingival health around the restoration. If this distance is less than 1 mm, it could potentially lead to complications such as wear of the restoration or damage to the enamel, while too much distance could affect the overall esthetics and function of the restoration.
