Abstract:
A method of replicating the relative position of an intra-osseous implant and abutment in a laboratory analog in an implant system having an implant for placement in an osteotomy of a patient, the implant having an inner end for placement in the inner part of the osteotomy and an outer end having a surface, an abutment receiving bore extending through the surface of the outer end of the implant, the bore being generally cylindrically shaped but formed with a locking taper for receipt of the post of an abutment having a generally matching locking taper, the abutment post and the bore having a longitudinal axis and the abutment being seated at a first axial position in the bore upon use of a first relatively low insertion force and a second further locked axial position in the bore upon use of a second relatively higher clinical insertion force, the bore extending beyond the post of the abutment in the second locked position,the method comprising the steps of taking an analog member formed with a generally cylindrical post having a longitudinal axis and being closely receivable in non-locking relationship in a bore of one of an implant and an implant analog, each having a generally cylindrical post receiving bore of a selected diameter, forming a stop surface on the post of the analog member extending radially outwardly therefrom and having a diameter greater than the selected diameter to limit insertion of the post of the analog member into the bore of said one of the implant and the implant analog, forming an index configuration on the analog member at a distance along the longitudinal axis from the stop surface essentially equal to the distance between an index configuration on an implant abutment and the surface of the outer end of the implant when the implant abutment is in the second locked position in the implant, and inserting the post of the analog member into the bore of said one of the implant and the implant analog until movement of the post of the ananlog member is limited by the stop surface on the post of the analog member engaging said one of the implant and the implant analog to obtain the replicated position of the implant abutment in the second locked position in said one of the implant and the implant analog as reflected by the axial position of the index configuration of the analog member.
