The tubular member has, at one end, a retention member for engaging a complementary retention member on the dental implant. The tubular member includes an internal passage adapted to receive a fastener for engaging a complementary fastener in the implant. The tubular member also includes an exterior sidewall portion adapted to form a positional transfer impression of the abutment in a dental cast.
