Where should occlusal contacts be located on an implant crown?

The optimal location for occlusal contacts on an implant crown is indeed on the central fossa of the occlusal surface. This positioning is crucial for achieving a balanced and functional occlusion. Placing occlusal contacts in the central fossa allows for the distribution of occlusal forces evenly across the implant's surface, which is essential for maintaining the integrity of both the implant and the surrounding bone.

Occlusal contacts located in the central fossa also promote proper alignment with neighboring teeth, which is important for efficient chewing and overall oral function. Additionally, this central contact point minimizes the risk of uneven forces that could potentially lead to complications such as implant failure or bone resorption over time.

In contrast, occlusal contacts on the buccal or distal aspects are less ideal as they may create an uneven distribution of forces that could lead to dysfunction or increased stress on specific areas of the implant. Allowing contacts to be anywhere on the implant crown might lead to unpredictable stress distribution and could compromise the longevity and success of the implant. Therefore, focusing occlusal contacts in the central fossa provides the best foundation for long-term stability and health of the implant and supporting structures.
