Dental Prosthesis Attachment System with Interlocking Retention

The single surface of interference is segmented into multiple surfaces of interference. The male member features multiple protrusions and the female member features corresponding recesses, creating multiple discrete contact points that distribute chewing forces and prevent detachment while maintaining reasonable structural complexity.

The attachment system employs asymmetric male and female members with complementary geometric features. The protrusions on the male member fit into corresponding recesses on the female member, creating an asymmetric interlocking mechanism that provides reliable retention under multidirectional chewing loads.

The attachment interface is segmented into multiple discrete protrusion-recess pairs distributed around the circumference of the male and female members. This segmentation provides multiple surfaces of interference that collectively enhance retention reliability while keeping each individual feature simple in geometry.

Multiple protrusions and recesses are merged into a single integrated attachment mechanism. The male member with multiple protrusions engages with the female member with corresponding recesses as one unified assembly, providing enhanced retention without requiring multiple separate attachment devices.

The attachment interface is divided into multiple protrusion-recess segments that can be manufactured using standard CNC machining or injection molding processes. Each segment is simple in geometry but collectively they provide the necessary retention strength to withstand high magnitude chewing forces.

The male and female members are made from materials with complementary properties - the male member from a harder material resistant to wear and the female member from a slightly softer material that provides frictional retention. This composite material approach enhances the strength of the attachment while maintaining ease of manufacture.
