| 摘要 |
The invention relates to a device for support of a denture comprising sleeves (1), columns (2) and a bridge construction (3). The upper part of the columns (2) is cone-shaped, and the bridge construction (3) is divided in separate parts each comprising a sleeve (5) with an inner cone-shaped portion. The sleeve (5) is provided with two wing-formed extensions (6) whereby the bridge parts are attached on a respective cone-shaped column (2) and the wing-formed extensions (6) are overlappingly connected to each other to form a continuous bridge (3) attached to the columns (2), which in turn are arranged in the implant sleeves by fixing screws (7). The bridge construction (3) is attached without looseness, and its parts (3, 8) are connected to each other following the attachment in a way that allows for compensation of obliqueness of the implant sleeves and a great individual adaptability. |
