摘要
A new dental implant system with positive abutment screw locking and retrieval mechanisms is provided. The abutment screw is positively locked by a keying pin to improve fatigue life. The abutment screw is also equipped with a special feature that greatly improves the retrievability of the broken screw from inside the implant. In addition, the keying pin is designed with a lock nut as a sub-assembly for ease of installation.
