Abstract EN

The prosthetic component of dental implant is attached on the abutment which is connected to the fixture with an abutment screw.

The abutment screw fracture is not frequent; however, the retrieval of the fractured screw is not easy, and it poses complications.

A retrieval kit was developed which utilizes screw removal drills to make a hole on the fractured screw that provides an engaging drill to unscrew it.

To minimize this process, the abutment screw is modified with a prefabricated access hole for easy retrieval.

This study aimed to introduce this modified design of the abutment screw, the concept of easy retrieval, and to compare the mechanical strengths of the conventional and hollow abutment screws by finite element analysis (FEA) and mechanical test.

In the FEA results, both types of abutment screws showed similar stress distribution in the single artificial tooth system.

A maximum load difference of about 2% occurred in the vertical load by a mechanical test.

This study showed that the hollow abutment screw may be an alternative to the conventional abutment screws because this is designed for easy retrieval and that both abutment screws showed no significant difference in the mechanical tests and in the FEA.
