| 摘要 |
The present invention is a dental structure for removably mounting a dental appliance, including a partial denture, bridge, or similar dental appliance in an oral cavity. The dental structure includes an improved male member comprising a substantially cup-shaped body, including a base, a cylindrical wall extending form the base, a projection extending from the base in the same direction as the wall, and a relatively large rectangular stop member that provides a positive contact with an upright wall of a female member. This new and improved feature provides an additional stabilizing contact surface and also serves as a stop surface to prevent the male member from pivoting toward the upright wall of the female member when the male member is fully seated on the female member.
