The objective of this paper is to compare the Nobelpharma implant system with that designed by Astra-Tech. The main difference between the two is in the design of the fixture-abutment linkage. With the Astra system, the abutment and screw form one unit, whilst with the Nobelpharma system there is a separate abutment screw. Both systems have been used to support overdentures. Linked bar retention between two implants has been used with the Nobelpharma implants, and individual magnetic or stud retention has been used with the Astra system. Each attachment mechanism has produced patient satisfaction.
本文的目的是比较诺贝尔制药公司的种植体系统与阿斯特拉-泰克公司设计的种植体系统。两者之间的主要区别在于基台-种植体连接的设计。在阿斯特拉系统中，基台和螺丝构成一个单元，而在诺贝尔制药公司的系统中有一个单独的基台螺丝。两种系统都已用于支持覆盖义齿。诺贝尔制药公司的种植体采用两个种植体之间的杆式连接固位，而阿斯特拉系统采用单个磁性或柱形固位。每种附着机制都让患者感到满意。
