What is it about?
The aim of this study was to investigate the mechanical influences of the implant-abutment connection type and inter-implant distance on the inter-implant bone by using three-dimensional finite element analysis.

Why is it important?
The maximum principal stress and microgap were evaluated. The stress values of the inter-implant bone decreased in the following order: IC, EC, and CC. The microgap decreased in the following order: EC, IC, and CC. Regardless of the type of implant-abutment connection, the stress of the inter-implant bone increased as the inter-implant distance decreased. The microgap barely changed as the inter-implant distance decreased.
Perspectives
A CC implant is a mechanically advantageous implant-abutment connection type for maintenance of the inter-implant bone. With an inter-implant distance of less than 3.0 mm, use of a CC implant might suppress absorption of the inter-implant bone.
