What primarily contributes to the retention of ramus frame overdentures?

The primary contributor to the retention of ramus frame overdentures is the use of ERA attachments. ERA attachments are designed to create a precise connection between the denture and the underlying supporting structure, typically relying on friction and interlocking mechanisms that enhance stability and retention during function.

These attachments are particularly advantageous in situations where minimal available space exists, as they allow for a more compact design without compromising the overdenture's overall performance. Unlike conventional denture adhesives, which depend on suction or adhesive properties and can be susceptible to breakdown over time, ERA attachments provide a mechanical form of retention that is less influenced by saliva or wear.

In the context of ramus frame overdentures, the unique design of ERA attachments offers advantages such as adjustable retention levels, which can be modified according to the patient’s needs and preferences. This versatility and reliability in retention when using ERA attachments make them a preferred choice for optimizing the functionality and comfort of ramus frame overdentures.
