The response of bone between two implants may be influenced by a number of factors. Previous reports suggest that the distance between the implants is a critical factor toward optimal bone response. This article describes the effect of three different interimplant distances with implants using an internal conical connection and a reduced abutment diameter relative to the implant diameter. The results of the study demonstrate difficulty in provision of general guidelines regarding implant position realizing the myriad of possible configurations of platform, dimension, and connection.
